You can read WJdiag Pro user manual from

Many of our customers have a huge problem with reading out Jeep Grand Cherokee 2.7 CRD fault codes. It is possible to see engine fault codes with key on-off method, but you can not clear faults without correct OBD diagnostic tool. Also disconnecting battery will not clear fault codes on 2.7 CRD Jeep Grand Cherokee. Sometimes car will clear faults itself after replacing faulty part and driving couple of kilometers twice, but not always. Until today they were correctly read out and cleared only with DRB III and Bosch KTS diagnostic devices. Those devices are pretty expensive and not reasonable to buy for private use. So we decided to make a free diagnostics software that is compatible with 2002-2005 Jeep Grand Cherokee 2.7 CRD and that would work with a cheaper device. So we made our own diagnostic software and designed it to read/clear Jeep WJ CRD engine and transmission faults. Our Jeepdiag and WJdiag Free software is very basic and is not comparable with professional diagnostic equipment. Our goal is to help the car owner to quickly view and erase fault codes without the need to run to workshop and pay money for it. It is mainly for people who sometimes like to fix their car in their home garage. Our Jeep fault code reader / cleaner software will never be sold for money, It is free forever – to everyone.

If you need more serious diagnostic software, then WJdiag Pro is for you, it can access to every Jeep 2.7 CRD control module and have all options – fault codes, Live Data values, functions coding etc.

Viecar ELM327 diagnostic device J1850

For hardware we chose ELM327 diagnostic scanner as it supports all OBD protocols and is compatible with 99% of modern cars. ELM327 is also pretty cheap, genuine ELM327 that uses genuine ELM chip issued by ELM Electronics costs about 50 EUR, Chinese USB clone (non genuine) costs about 10 euros in ebay and every car owner can afford it.

Current version is Windows based and works with ELM327 adapter. This new software can read engine and transmission fault codes and also cleared them.  Other modules – ABS, Body, Instrument etc., are not supported. There is no explanation of the codes in the diagnostic program, it just shows what fault codes are stored in your car’s engine/gearbox. You can check explanations at or just google them, there are a lot of tutorials on the web. Be mentioned that diesel and gasoline Jeep fault codes are different, so if you look from the web, then only look 2.7 CRD codes. Since this is Mercedes engine, many codes are same that in MB. Be mentioned that diesel and gasoline Jeeps codes do not match – if you have 2.7 CRD, then do not look fault code explanations for gasoline models.

Our Jeep fault code scanner is Windows based and should work on Windows XP and greater. We tested it on 32-bit XP, 64-bit windows 7, Windows 8 with ELM327 USB versions and Windows 8.1 Tablet with genuine ELM327 BT version and it works perfectly. This software connects with ELM straight to COM port and if you use BT version, then you should pair ELM327 and connect it with your computer before using our program. Also be sure that you have BT drivers correctly installed on your computer.

You need to have Microsoft .NET Framework 3.5 or greater installed on your computer. Most computers already have it.

Android version working with Android 4.3 and up.

There are problems with Chinese BlueTooth ELM327 clones. It is true that the ELM is only as good as it’s user. Genuine ELM is well made and can communicate through all OBD II protocols and is only limited by its user’s wisdom to use all ELM options. Different case is with Chinese clones – there are nice labels on those devices “Supports all OBD II protocols”, but real life is different. Newer Chinese devices are different from what they used to be. They used to copy ELM chips, but now they made a new device with their own firmware for chips inside the device, added some major protocols and called it ELM327. Those devices do not support necessary commands for ELM configuration and some of them even does not support necessary protocols. Chinese devices are working with some diagnostic software like Scanmaster ELM or Torque PRO on many car models, but 2.7 CRD Jeep ECU and TCM data transfer is much more complex and newer clones are not supporting them. This is the reason why our diagnostic software does not work with many Chinese ELM327 devices. Older Chinese USB clones seem to be working well with our software, problem is with many newer devices. We cannot do anything about this. With problematic ELM327 device you will get answers: Fake ELM.

China is a country of surprises and you’ll never know what you get – working device or garbage. At the bottom of this page you can find some feedback and we are pretty sure that those who can not get our diagnostic software to work, are using fake ELM device. Avoid Chinese ELM327 clones, they are not working correctly! ELM327 BT and USB with original chip are working fine. If you want to be sure, buy a device with genuine ELM327 chip.

Configuration commands that ELM must support are:
You can ask about those commands from seller before buying Chinese ELM device.

Recently we find out that Chinese device called Viecar BT 4.0 working fine as well. It is cheap device, price in Aliexpress is about 10 eur, EU prices for same device are higher, 20...40 eur. Image of Viecar BT 4.0 is on up side of this page. If you decide to buy Viecar device, then get exact match with this image, because Viecar makes many ELM327 devices and other models will not work. You can get this device from our shop page as well.

    Hi, I contacted the guy in Australia who sells the ELM327 units you recommend on this website. He took 4 days to return my email, I think he wrote 4 words in totally. Refuses to answer his phone, and told me his unit WOULD NOT WORK with my 2004 WJ CRD. Honestly he came across as an arrogant A-Hole who was completely unhelpful. Maybe you could remove the link to his website as he has no interest in doing business with people and won't sell you an ELM327 module. Thanks

    Hi Juraj.
    Technically, firmware upgrades can be added to WJdiag, but we will not add it due to many poor ELM327 devices. Firmware upgrade requires data transfer without any mistakes and ELM327 is not so good device. Many WJdiag users are using poor ELM327 devices that may miss some data during upgrade and it will cause faulty control module.

    Hi, Kaido. Can I change the minimum battery voltage via WJdiag pro? P2602 occurs after a long car downtime. Or do I have to go to an official dealer to re-flash TCM?
    And I didn't understand how to count the correction difference. How do cylinders work? 1-2-4-5-3?
    1 injector -0.32
    2 injector 0.45 => 0.77

    2 injector 0.45
    4 injector -0.09 => 0.54

    4 injector -0.09
    5 injector 1.01 => 1.1

    5 injector 1.01
    3 injector -1.02 => 2.03
    Am I right?

    Pour Wrangler, vous devez utiliser wiTECH MicroPod ou obtenir OBD JScan sur Google Play.

    Engine and transmission are using for diagnostic ISO 14230-4 KWP and all other modules are using J1850 VPW data protocol. Seems your ELM327 does not support J1850 data transfer and you should replace it. For example those ELM327 devices are working fine with Jeep:

    Hi Kaido
    The engine of my Grand Cherokee 2.7CRD kept cutting out under power, but would always restart after coming to a stop and toggling the ignition, most frustrating and dangerous when over taking!!. To cut a long story short the problem was down to the fuel filter, once replaced no more cut-outs. I had obviously run the diesel low at some stage and the sediment in the tank had been sucked into the filter.
    Just another check to make before lining the dealers pocket with even more cash

    Hi Kaido
    PCB received and fitted very easy to do
    2 weeks now and the it's like a new vehicle
    So glad I replaced the unit after over a year of trying everything else, perseverance, deliberation and frustration the problem is fixed
    I'm so happy, thank you for everything
    I have confidence in the vehicle and its reliability
    Your website is a blessing for anyone seeking the only fix for the transmission fault.

    I buy an ELM327 on eBay. The same of the picture on your site. But I launch your software jeepdiag, it is written this fake elm. And I would buy a veritable elm on the site ELM327.en but it’s written the nos isn’t compatible whit your software.

    Which one should I buy?

    I have a default code P0702 and P0703.

    It’s very important please

    Thank you for all the info. It is a very well documented website. I had a problem because I installed a bad battery on my car and I started to have all sorts of issues. In the diagnostic process I found and fixed the o-ring problem. All good except for the TCU resetting procedure. It would be nice if you add some instructions about that. Found them on Youtube:

    All the best from Australia,


    17. December 2019 10:26
    Pro version excellent, however one question for transmission control: TCC locking, now it seems that TCC locks at 1650RPM transmission output speed regardless of the gear. Is it possible to change that RPM value via WJdiaG or is it coded in actual TCM SW? Would like to try reduce RPM setting, allowing TCC to lock earlier in order to reduce fuel consumption.

    Thank you for you helpful and informative web site.
    I am experiencing P2210 (TCM) with P0702 and P1242 (canbus message missing) (PCM)
    I am seriously considering buying your shifter module.
    In your experience what is the correlation P1242 with P2210 is there something else I’ve overlooked?

    Ciao D Ascoli.
    Di solito l'auto guida bene dopo aver sostituito la parte rotta, ma a volte è necessario cancellare i codici di errore del motore e della trasmissione per uscire dalla modalità Limp. Dipende da quanto hai guidato con la parte rotta. Hai sostituito la scheda del cambio, ma sembra che non hai cancellato i codici di errore e la macchina rimane in modalità Limp.
    Solo i dispositivi diagnostici compatibili per questa vettura sono Chrysler DRB 3 (dispositivo del rivenditore), Bosch KTS (dispositivo generico, molte officine ce l'hanno) ed ELM327 (dispositivo comune) con il nostro software WJdiag gratuito oa pagamento. Tutti gli altri dispositivi diagnostici non possono accedere correttamente a questa vettura o mostrare risultati errati. Se non si dispone di uno di questi dispositivi, chiedere all'officina locale se dispone di uno di questi dispositivi diagnostici, quindi l'officina può eliminarli. La cancellazione dei codici difetto richiede pochi minuti e non dovrebbe costare molto.

    Other issue is that Scantool have bug in their devices and STNxxxx devices will not work with Jeep. I talked about this bug with them, but they are unable/do not like to fix it.

    hello. yesterday I bought wjdiag pro. I have elm327 on the module stn1170. The program connects to elm, but I have the message no answer. Other applications such as piston or torque work without a problem. Jeep Diag also works.

    Ho acquistato e fatto montare in officina la Vostra scheda cambio automatico per Jeep Grand Cherokee 2,7 Crd wj anno 2002 , ma la centralina del motore non la riconosce , e la luce avaria motore nel quadro strumenti resta sempre accesa , che bisogna fare ,per farla riconoscere ? Grazie se mi risponderete

    15. November 2019 02:53
    I'm finding the JeepDiag Pro very useful.
    My ELM327 tool can read passenger door, but doesn't read Driver's Door. Would this be prob with my ELM327 tool or something else?
    Can't get any function to work from Drivers Door controls, yet the windows, for example, will work using Diag tests on passenger door - but can't access DD control. Any suggests?

    Hi Kaido,

    Thanks for the reply.

    All my numbers look correct but car cuts out at high revs under load. I have replaced low and high pressure pumps and injector leak back test all looks ok. Is there a test I can perform to narrow down the problem do you think?

    Thanks again

    28. October 2019 08:46
    Hi Simon.
    287 bar is fine. I made comparison tables with our test cars from engine Live Data values, they are located at WJdiag user manual page at

    28. October 2019 07:35
    Simon Skinner

    I purchased your pro software and its ace, for the small amount of money it costs I would recommend to everyone! I am constantly getting a P1130 error - small leakage detected. DO you know what a standard fuel rail pressure is on tick over? Mine is 287 bar....any ideas?

    Hi. I got 2.7 wj . P0700. I nead to scan the transmission. Ime in Middelburg mpumalanga. Where can i by this tool

    26. August 2019 21:37
    Great app, thank you Kaido. Injectors test is very helpful (now I know that my huge black smoke does not come from them...!).
    Does anybody knows how to check the good working of the EGR actuator with this app? Thank you for your answer(s)!

    Hey guy‘s
    I love your side, here i‘ve been found so many helpful tips and your PCB works gratefully.
    But there is only one thing i need to know.
    Is a WJdiag pro availabel on windows? I don‘t use android...

    14. August 2019 17:28
    Приветстаую! Купил версию про для андройда, установил, двигатель и акпп отлично кажет ошибки и текущие данные, но в другие блоки заходит,((( видно что пытается, но пишет "нет ответа от елм". Необходимо посмотреть ошибки в srs, и данные в "штифтере", как быть? Неужели версия про не читает остальные системы и разница с версией фри втом, что про кажет текущие параметры мотора? Спасибо.

    5. August 2019 21:03
    Hi. Will this work on a WJ 4.7?

    15. June 2019 19:39
    Hello Lothar.
    Android does not support OBD data transfer through USB and we can not add such option to Android.
    We will not make Windows version of WJdiag Pro, because it needs a lot of programming time. Instead of making new version, we are focusing on upgrading current Android version of WJdiag Pro.

    Ich habe das ELM327 mit USB des rumänischen Herstellers. Leider funktioniert es nur beim Windows Laptop, nicht aber bein Android Smartphone. Ist ein release für USB angedacht?

    habe ein android tablet (7.0), elm327 bluetooth v1.5 und wjdiag pro gekauft. immer wenn ich mein wg 2.7crd scannen möchte, reagiert das inteeface nicht oder baut keine verbindung auf. jetzt habe ich elm327 usb gekauft und wjdiag auf widows instaliert. und auch da wird kein interface erkannt. mit drb3 konnte der wg problemlos ausgelesen werden.

    Tell me, are there plans to update JeepDiag in Russian? The site itself could also attract a large audience of Russia if it were in Russian. Do you plan to expand the diagnostic program or not? Is it possible to use the purchased program on another medium, not on the phone, but suppose you transfer it to a tablet?

    28. May 2019 06:06
    Yes, WJdiag Pro can read BCM fault codes.

    28. May 2019 03:45
    Does your pro version read BCM codes? Me front passenger door is freaking out.

    27. May 2019 11:46
    Simon Skinner
    Right...I have a problem and wonder if you can help.

    Had the 'black death' with sever leaking injectors. Seats cleaned and re-cut. New washers and bolts. Car now cuts out when going over 2,000 rpm and get a p1130 error. I get no errors when ticking over or under very light load. It ran fine before so assume injectors are not faulty.however I have used your software and got the following readings:

    cyl 1 fuel - -0.40
    cyl 2 fuel - -1.01
    cyl 3 fuel - +1.50
    cyl 4 fuel - +0.93
    cyl 5 fuel - -1.03

    They are not spot on but not too far apart.

    Also I have the following:

    RPM - 750 rpm
    Fuel pressure regulator output - 88%
    Fuel rail pressure Actual - 236 bar
    Fuel pressure set point - 278 bar
    Mass airflow - 541 Mg/s
    Mass airflow voltage 2.18v

    Any thoughts?

    Thank you as always

    Hello ,
    I bought the WJ diag Pro software but cant find how to turn ON FULL HIDRAULIC FAN.
    Is there a option ?

    26. February 2019 07:49
    Hello, Włodzimierz
    If you can not read engine data, then probably issue is with your ELM327 device. Please try to connect again and after few attempts send log file to us for examining. Log file can be sent through settings page (3 dots on top right on the screen).

    25. February 2019 23:01
    I bought the WJdiag Pro app. In my 2.7, the CRD does not read the engine data. What should I do?

    23. February 2019 19:55
    Доброго времени суток!
    Скажите пожалуйста, возможно вы сталкивались с такой проблемой.
    При наборе скорости, в диапазоне оборотов двигателя 1800-2000 происходит вибрация двигателя похожая на пропуск зажигания на бензиновым двигателе. Ошибок нет. Особенно сильно вибрация ощущается на холодном двигателе. Не один специалист не может найти причину. И я заметил что очень много wj страдают этой проблемой.

    15. February 2019 00:28
    Hi.. when changing from bar to psi my boot pressure still reads the same figure..

    7. February 2019 16:42
    Hello Kai.
    You need to install USB drivers for COM port. Usually Windows will install drivers itself, but if not, then you need to install them manually. Check at CD disk you got with your ELM327 device, there should be a folder with drivers on the disk. After installing drivers correct COM port will appear to COM ports list in JeepDiag.

    6. February 2019 06:23

    I have a elm327 plug connected with usb. Your program is not able to find the com port my usb cable is connected to? I can use a usb connected ELM?


    1. February 2019 10:49
    I want to buy the bt elm you describe, but the web doesn't work. I've tried in ebay, but I haven´t found it neither. Could you tell me the correct link for buying?

    31. January 2019 08:49
    Hello Sergio
    If you buy program, then there is one time payment for purchase and after this you can use WJdiag on single device as much you want and no extra payments are required. If you change your Android device, then you can make backup from old phone through Google and WJdiag will be transferred to new device for free. You need to have Google Play account for this.

    30. January 2019 20:02
    Hello Kaido, Some time ago, I purchased the European elm327 and used the Diag free jeep successfully. I want to buy the Pro version. I would like to know if, when changing cell phones, I can maintain the program and not have to buy it again. Thank you

    10. January 2019 12:19
    Thanks a lot You Guys are great. I already have the shifter Modul from You and its working perfect.

    9. January 2019 21:11
    Engine and transmission are using ISO 9141-2, K-Line and all other modules are using J1850 VPW.

    9. January 2019 17:37

    Hi wonder if you can help, if I run the mass air flow test on my jeep at idle it reads it as 30 mg/s but on my dad's it's 233mg/s why is there such a big difference, is mine faulty, or what should it be

    2. January 2019 19:52
    WJdiag Free is good if you need to check or clear some fault codes in engine and transmission, WJdiag Pro is for more complicated diagnostic.
    With WJdiag Free you can read and clear engine and transmission fault codes, nothing else.
    With WJdiag Pro you have access to all modules your car has, like ABS, body, doors, parking sensors etc. Every module has different options like senor Live Data, Input-Output values make some coding etc.

    2. January 2019 09:05
    Hi Kaido,
    Thank you for developping this tool ?
    What is teh difference between basic WJdiag and Pro WJdiag ?

    My ELM327 device does not support wifi or bluetooth, so I can't use pro android software. Would you have a windows version for Pro WJdiag ?

    Have a good day.

    18. November 2018 13:58
    Injector test shows how good or bad injectors are. Perfect value for new injectors are near 0.00 and with time injectors will wear out. ECM is measuring RPM of each cylinder and if injector is worn out, then ECM will correct fuel quantity for each injector to keep engine running smooth.
    Measuring must be done with warm engine, injectors must be equal, few examples:
    Some injector has +2 and some has -2.3, total difference is 4.3, it is too much and injectors should be replaced.
    Some injector has +2, other +1,8 etc., total difference 0,2 is pretty good, no need to replace injectors.
    If injectors are not equal, then car can smoke, fuel consumption is high, engine is not running smoothly, in extreme situation car may not start.
    Total difference 2 or less is not a big problem and car can drive well.
    Injectors have codes 1, 2 or 3 stamped on case. To get best performance, same values should be coded into ECM, it can be done through Engine Tests, Injector Learn. Just place correct codes shown on right side and save.
    There is a little trick to optimize fuel consumption with old injectors through changing codes in ECM. With warm engine drive on flat road with cruise and check fuel consumption on ceiling console. Change code on injector you think is working incorrectly and compare fuel consumption again. To get correct results, fuel consumption must be reset from ceiling console every time you are measuring. With such playing fuel consumption can be reduced up to 2 L/100km (best result I know), depends on injector conditions. Of course results can be reversal if initial settings were most optimized, so better is to remember settings before coding.

    17. November 2018 11:25
    Great product thanks for taking the time to develope it.
    One question, can a injector relearn be performed to optimize the injectors in there current condition? If so does it give you step by step instructions on how to do this?
    Thanks again.

    15. November 2018 17:55

    Diagnostic software is made for WJ 2.7 CRD and it is working with your car.
    We are not making diagnostic compatible for MacBook, sorry.
    At the moment you can not use Android device with WiFi ELM327. You can use basic app with WiFi adapter if you have Windows computer and can use some additional port redirecting software like HW VSP.

    5. September 2018 19:20
    Those codes are stamped to injectors and to get best performance, ECM must know what are injector codes.
    If injectors are worn out, then playing with codes can make engine run smoother and save fuel economy.

    5. September 2018 06:31
    Hi Kaido,

    now You've added the fuel injection parameters. Great!
    Just wonder what is the logic (manual) for injectors learning option?

    Hi Kaido,

    I have used both versions with great success. Now the Pro version gives "free time over" despite reinstalling it.
    The only thing I missed in Pro was fuel injector parameters (fuel correction) - this option would give great value to Your program as would help to diagnose faulty injectors which sometimes is a case on these old machines. Other wise the program is great tool.

    Hello Gustavo.
    Jeep gasoline models are using Chrysler SCI data bus for Engine and Transmission diagnostic, but ELM327 does not support it. Unfortunately there is no other low price device in the market that is Chrysler SCI compatible and we should develop new device for it. Probably we will not do it.
    All other modules like ABS, body, doors, media, parking aid etc. should work with current app.

    Hello Andy.
    Our Jeep diagnostic software does not work with iPhone and WiFi ELM327 device. You can use Windows computer with WiFi ELM327 if you have some port redirecting software installed like HW VSP. It will redirect WiFi TCP/IP traffic to COM port.
    Clearing P0702 from Engine only does not have point, because if some fault remains in Transmission, then in next start TCM will report about it to ECM and P0702 will appear again. 'First clear Transmission faults and then clear Engine ones.

    Hi I have WJ Jeep 2.7 CRD 2002 year, with error code P0702.

    I bought a replacement PCB from a dealer in the UK (one of your boards) and fitted it, but the issue is still present (limp mode and engine managment light still on), I bought a Wi fi ELM 327 reader from the site recommended below and have used it with my I phone to try and clear the fault code (it immediately reappears) and read the error code using the Auro Doctor app.
    I am unable to get any fault codes using the ELM 327 reader and app. Do you have any ideas what can do please?

    Thank you

    Such an awesome app!
    The pro version has now expired.
    How can I purchase it?

    10. January 2018 07:40
    Kevin, you need to install USB ELM327 drivers first to your computer. Probably you got cd disk with your ELM327 device.
    Fabrizio, WiFi ELM327 will work only with Windows computer if you are using some Com port redirecting software.

    9. January 2018 09:42

    Hello Eduardo.
    You can use only Bluetooth ELM327.

    Andrew, OBD socket have +12 volts without ignition and you can hold ELM327-phone connection, but all car modules are switched off and you can not make any diagnosis.

    Hi There

    I have an ELMScan 5 with an ELM 327 Hardware Revision: 3.2 and Firmware Revision: 1.2a.

    It's original with RS232 output, but I have a cable from RS232 to USB to my pc.

    It communicates nicely, but comes with a mistake. FAKE ELM327 is that the Firmware that's too old?

    Will there be a software ver. for iPhone or iPad sometime?

    For anyone experiencing the same problem as me:

    For some reason this app was not able to communicate with my transmission. These guys are working on a new app which I was able to test. The new app communicates just fine with the TCM, and now my Jeep is on the road again.

    Don't be afraid to send them an email, and make shoure to give a donation. They're saving you a lot of money;)

    Just received the BT ELM327 v2.2 from Romania today( I want to access the gearbox, as i have the P0702 error code on my 2002 Jeep GC 2.7 CRD.

    I tried your software on Android and 2 different Windows 10 PCs, but none of them were able to read or clear the gearbox. It was able to read and clear the ECU on all devices though.

    Any ideas on how to solve this?

    I am very dissatisfied!
    I ordered and received usb elm 327 from Romania.
    to connect to your software is impossible!
    your software only offers one COM 3 port, and I can not connect to the PC.
    I have yet to download drivers usb on
    the software tells me that I am not connected to com 3.
    how to do.????
    it is a situation that costs me dear and that does not solve anything and that lasts in time !!!
    I tried with two pc (windows 7)
    and it's the same problem !!
    thank you for following up on my message.

    7. September 2017 13:14
    Fonctionne parfaitement en bluetooth sous Android, mais comme déjà précisé, uniquement avec un VRAI ELM327.

    Habib, Chrysler made their own data bus protocol that is used only in older Chrysler Group cars, including Grand Cherokee WJ 1999-2001. Unfortunately ELM327 does not support this protocol and we can not add older Jeep models.

    12. May 2017 21:44

    Est-ce qu'il y a un module de diagnostic pour G Cherokee WJ modèles 1999-2001? Si oui pourriez-vous m'aiguiller la dessus.

    Oh and if you download and use this diagnostic software, remember how frustrating it's been not being able to diagnose or clear the codes on your Grand Cherokee 2.7 CRD! Send these guys some money in appreciation for all the time they've spent on this (even if it's not a lot), they deserve it!

    5. May 2017 18:17

    Works great with the car.pulse cable -

    Tried a cheap Chinese cable but a waste of time, I recommend you buy one from these Romanian guys!

    Leider bekomme ich immer die Meldung: On this Com Port no correct ELM connected!
    Treiber i.O., ELM327-Clon, funktioniert bei anderen Marken mit ForScan, Carsoft demo, etc.....

    Was kann ich tun, damit JeepDiag mein Elm erkennt?

    Grüße Alex R

    14. April 2017 13:53
    Graziano, It is possible, because engine data transfer uses "Fast Initiation" (ELM command AT FI) and gearbox data transfer is working without this command. So your ELM327 does not support AT FI command.

    14. April 2017 10:45
    I bought an ELM327 USB. Is it possible that "read engine" function gives "fake elm" response while the "read gearbox" one works perfectly?

    25. March 2017 21:45
    Yes, Windows version is working with USB ELM327 as well.

    25. March 2017 21:30
    Hi! this software can work also with a USB ELM327 version? Thanks

    17. March 2017 19:17
    Bonjour, suivant vos conseils j'ai acheter l'ELM 327 que vous conseillez sur votre site et j'aurais deux réflexions à faire en effet, lorsque on commande sur le site roumain il y a 19€ de frais de port pour un tout petit objet qui coûte environ 48€ et l'objet n'arrive qu'après 4 jours de transport, ce qui semble très long pour ce prix de transport et surtout quand on est en panne, ensuite l'appareil fonctionne avec vos logiciels, mais malheureusement il est intégralement en Anglais et aucun moyen de changer de langue, ce qui est compliquer quand on parle mal cette langue, pouvez vous changer cela, afin que l'on puisse choisir sa langue pour mieux comprendre le fonctionnement de l'appareil ?
    Sinon il fonctionne, reste à voir si après réparation de ma panne il parviendra à rétablir le bon fonctionnement de ma voiture en effaçant les codes défauts.

    My 2002 2.7 Jeep started to go into temporary limp mode almost every second day. It had done that for the last year or two but until now, it would only happen like once a month so I wasn't really concerned. The check engine light would come on and the power would be limited. Restarting the car would instantly fix the problem until the next time. Doing the key trick I found out that I had quite a lot of codes with P0700 and P0702 being some of them. I managed to fix the limp mode problem just by cleaning the whole PCB board and the gear selector base that houses the magnets with cotton pads soaked in contact cleaner. I also sprayed contact cleaner on all of the connectors that where under the central console and had to be disconnected from the PCB board to remove it. Just in case cleaned the TCM connectors as well. I think that the magnets were too dirty for the PCB sensors to detect the correct position of the gear selected but I might be wrong. Been happily driving my Jeep for a month now without check engine light turning on or the car going to limp mode. Thank you Kaido for such a awesome website.

    For Helping give no code elm have no code.
    Thanks sale the car is better

    15. February 2017 08:32
    P1685 is SKIM SYSTEM INVALID SECRET KEY IN EEPROM. If you can start your car, then do not worry about this and focus on P0700 and P0702.
    If P0700 or P0702 is active and comes back after clearing, then there must be some other code stored in transmission that is causing P0700 and P0702.
    P0700 and P0702 are "Transmission generic electrical" faults and they are stored in ECM (Engine Control Module). They appear only if transmission has an active fault code. If transmission has some electrical problem, then fault will be stored in TCM (Transmission control Module) and also TCM will report about this to the ECM. By this report ECM will store P0700 or/and P0702.
    For this reason P0700 and P0702 can not be alone.

    First, thanks for the android version, it works just fine. I was able to use it with my generic obd2 BT adapter to reset the gear on my wj wg crd 2.7 2004.

    I would like to ask you guys to enable ratio setup - we the jeep owners would like to increase the tier diam and compensate with bigger gear ratio.
    Increasing the gear ratio require updates to the gear computer otherwise it got into limp due to "mismatching" speed report from the abs sensors.

    Works great with this ELM327:

    WIFI is not supported, but you can use some Virtual Serial Port driver like HW VSP with your WIFI device. It will redirect TCP/IP traffic to COM port. It is tested and will work fine with Jeepdiag.

    Have you the jeep diagnostic software in Wi-Fi version? Accidently I bought the Wi-Fi version from the website what you mentioned, from Romania.

    10. September 2016 10:15
    Where is the best place to buy an ELM327. I am in South Africa.

    31. August 2016 10:04

    Cleared all codes with none remaining.
    Tomorrow I take her for a drive and see.

    Samuel, at the moment Chrysler DRB 3 is the only device that can do everything you need.
    At the moment we are developing an app that is almost dealer level for WJ - supported will be all modules of those cars: keys, immo, ABS, body, doors, entertainment etc. Also live data and tests. It is huge work, it takes time and we are on time if we can release it by the end of this year.

    Rev Samuel MSE Kayuni
    My name is Samuel from Malawi Africa. I own a small business of renting and selling used 4x4s from UK market.
    Latterly have sold many Jeeps with Diesel engines
    CRDs. Right now I have 10 Jeeps parked at my yards have various issues like Keys not recognized,immobolizers, gears limp modes etc
    I bought various diagnostic scan machines like launch, dvatage and the last one called DG VSI2554 I need soft ware that I can install in the machine that can handle issues of my Jeeps. Any idea please help.
    I look so stupid to the people have supplied Jeeps of various models. I love these vehicles when running properly.

    Hi thanks
    I've encountered an issue with aux position on the Ignition where the radio is suppose to go on when the vehicle is of, immediately after clearing codes with your software. Got the same elm 327as in your pic connecting to usb. have you anny solution or help.

    5. May 2016 18:32
    We got USB version from car.pulse and yes, it has genuine ELM chip (ver 2.1) inside and it is working correctly. As it is using genuine ELM chip made by ELM Electronics, then all ELM commands are supported.
    Those Romanians are making good stuff for reasonable price and their devices are worth every penny.

    23. April 2016 12:14
    Are you sure elm327 USB (not BT) from car.pulse on ebay works ? because I've just buy one on ebay (from an other seller Diagscan) and it does'nt work, message : "communication error : fake elm" (I think it's a chinese version). My ELM is an usb V1.5a.

    14. April 2016 20:07
    Hi guys.
    I received the real ELM327 Bluetooth from Romania today.
    Your jeepswj software reported it as ELM version 2.1.

    I connected the Bluetooth ELM to a virtualized XP Pro SP3 running under Parallels Desktop 9 on my Apple laptop (OS 10.7.5).
    A little tricky to pair it but I get it working.
    I successfully erased a remaining default engine code on my 2.7CRD.

    I also paired the ELM with my smartphone (Galaxy S2) without any trouble.
    But I don't have appropriate app to communicate with the jeep TCU, I can just read engine codes (french OBDfacile app).

    Would you send me the (beta) Androïd app so I can try it ?

    Thanks for all your work !!!

    7. April 2016 11:36
    Edit from last post : still has BT units, it was a server error. I ordered one and I hope I can check the Android pre-relase software soon.

    7. April 2016 09:30
    Hi Kaido.
    Just to let people know that BT original ELM327 is out of stock from website above. I emailed the seller. Without BT unit I can't test the Android pre-release ...

    6. April 2016 06:23
    Thankyou, your advice got the job done, I am now enjoying driving at more than 30mph

    2. April 2016 21:55
    Just for the feedback, my elm 16bit branded ROH I'd with a previous software doesn't works. I will try an other later.

    Nice site, a lot of infos about WJ et some produts interesting.

    GB from France.

    2. April 2016 10:43
    Will you make a version for Android that can be used with WIFI conection any time soon?

    WOOHOO, we got our first donation today from a happy user for our diagnostic app:)
    It happened after 10 months and 3000 downloads. Thank you Fernand.

    18. March 2016 11:42
    We got first Android release to read/clear codes and it is in test stage now to figure out if everything is correct with connection and data transfer. It is not ready to publish, but I can give app link to those who would like to test it. All testers are welcome, just write us through contact form.

    18. March 2016 11:16
    Is it long time to the android app is finish? I have problems with using the pc.

    25. February 2016 16:51
    We did not have any WIFI ELM when we made our software and it will not work. Probably we will not upgrade it cause at the moment our goal is to make an Android version.

    15. February 2016 12:30
    Hi guys !!
    Does your software works with WiFi ELM module ?
    I got one from a friend before receiving the cabled unit from China (MartyVayne's link, thanks to him if it works for me !!).
    It may be tricky to connect the ELM from your software (I don't know which port WiFi could use).

    11. February 2016 07:35
    Ragazzi siete grandi grazie
    Il vostro programma funziona alla grande con Windows xp è Elm 327 usb Made in Cina
    Appena collegato porta com 3 legge e resetta tutti gli errori del motore e del cambio del mio GC WJ 2.7 crd del 2002.
    Sarebbe bello riuscire a controllare anche eventuali problemi del climatizzatore o altro
    Sono ansioso di provare anche la versione Android
    Complimenti e Buon lavoro.

    Elmscan 5 Update.
    Reads the gearbox codes but not the engine codes.

    7. February 2016 15:49
    Yes, this message means that your ELM327 does not support necessary commands that are required for Jeep diagnose. It is a common problem for many Chinese devices. With genuine ELM327 chip all commands are supported and it will do the job. Better is to get ELM327 with genuine chip, but you can try next Chinese device until you get working one, many Chinese devices are also working fine.

    For example Vgate iCar2 BT device worked well, but until manufacturer has not confirmed supported command list, we can not be sure that all Vgate devices work. Vgate is not very cooperative to answer to us, but we will keep on asking them.

    I bought a Chinese ELM327 cable connecting to your program, I appeared massage FAKE ELM.
    Does this mean that I have to buy original cable?
    Thank you .

    7. February 2016 15:08
    At the moment only Windows version is available. We are working with Android and will add it to site ASAP.

    cannot access the download via android or ipad..Is it still available?

    6. February 2016 16:04
    Anyone used this with an Elmscan 5 compact?

    5. February 2016 10:38
    can't wait for android version to be released!

    3. February 2016 14:38

    Tank you, my Jeep-Gearbox works again ! The software has worked perfectly with an ELM bougt for 15 € by ebay. It looks like this, you showed on your side.

    2. February 2016 21:25
    Hi this is great, does anyone have any UK links to working fake elm devices?
    Took a gamble on the Chinese fake but didn't work.

    2. February 2016 09:15
    We are working with Android at the moment and hope to finish it within some days. Just little more patience.

    2. February 2016 09:05
    Thank you! It works perfect, even with a Chinese fake and Windows 10. When will the Android version be available?

    1. February 2016 18:33
    Hi Kaido,

    when do you think the Andoid-Version is ready to use. We are already waiting impatiently for the app :-)


    1. February 2016 16:49
    It means that your ELM is Chinese fake and does not support basic ELM commands. Using Chinese ELM327 is like lottery - you never know if it works or not. Try to get other one, preferably with genuine ELM chip.

    1. February 2016 12:36
    hello with my usb elm 327 i have the message "fake elm"
    i use window vista.

    27. December 2015 17:08
    It means that your computer can not connect with ELM. Be sure ELM Com drivers are installed and choose correct com port where ELM is connected.

    27. December 2015 15:42
    Antonio Moreno
    On this Com Port no correct ELM connected!

    22. December 2015 17:16

    j'ai testé sur ma voiture et ça ne fonctionne pas, jeep wj 2003 2.7 crd

    le logiciel ce connecte au cable mais ensuite pas moyen de lire les code d'erreur, avec le conctac, sans contact et même moteur tournant rien ne se passe.


    22. December 2015 09:35
    We will work with android on mid January and hoping to finish within couple of weeks.

    22. December 2015 07:40
    Hello. When will the android app software come?

    19. December 2015 08:39

    Hi, software works fine with iParaAiluRy ELM327 USB Interface bought on amazon:
    It has the PL-2303 XA/HXA chip build in, which only works on windows XP and Windows7, myself I use an Eeepc with windows XP.
    Engine and transmission errorcodes reading and erasing perfectly!!!
    I´m looking forward for the android version.
    Many thanks to the developer, who made it possible to read and erase error codes on Jeep WJ/WG 2.7 crd!!!

    16. December 2015 20:00
    Hi, software works like a charm.
    Used USB ELM 327 v1.5 Chinese clone. Bit of a gamble, but worked first time!
    Costs about 7 euro's on ebay which includes international shipping!
    Slow on arrival (takes about 2 weeks), but quality seems ok on first glance. Comes with driver CD, but didn't need that. Plug and play on Windows 7.

    Able to read and clear two old codes from engine and reads transmission no problem.

    ebay link:

    seller's name is is eto666

    Order and use Chinese clones at your own risk, just sharing my personal experience with this particular product.

    Hi Kaido,
    Thank you so much for your help and advice on my Jeep issues.
    I downloaded your free software and bought a ELM from the site you
    suggested (
    All good, retrieved/cleared the fault codes.
    Can't thank you enough - you saved me a lot of cost at the Dealership.

    5. December 2015 13:41

    bought the ELM327 usb v1.5a OBDII protocols and when connected to 2002 grand cherokee 2.7crd I get error messages Not supported Engine & Not supported TCM when trying to get fault codes.... trying to find codes and clear (in limp home mode), cleaned all contacts on gear selector module and want to clear fault codes with no success :(

    2. November 2015 23:21
    Hi, I would like to thank you for your software, it is amazing!!!
    It works with my old Serial-USB ELM327 ver1.3a OBD interface on Windows7 32 bit.
    (first pluged in the ELM, let windows to install the driver to COM9, then start your Software. Choose COM9 and it worked first time!)
    Your software were able to read both Engine and transmission error codes and cleared them as well.
    Thanks again.

    29. October 2015 22:00
    Hi just to let you know your program worked fine on my 2002 grand cherokee. I had a list of fault codes resulting in limp home mode and it cleared the lot! fantastic!! thank you very much.Don't suppose you do one for the ABS system as I've had a speed sensor fail and need to clear the light after I've replaced it. Thanks again anyway.

    Windows 8.1 enterprise (USB type ELM327 adapter). Device manager named port:com3, no other ports present. Software found and connected to com3 but did not communicate With car. Renamed com3 to com1 in device manager and everything worked fine.

    7. September 2015 12:25
    (The same Tom like below)
    With the USB type of ELM adapter - it works like a charm!
    Great software - the Android version wuld be perfect add!


    29. August 2015 11:58

    So far with my BT ELM version on Win10 Dell laptop I was unable to read anything. I'm not sure if ita due to the PCELM connection or more to the ELM istelf. I can only say that with the same adapter and my cellphone I can connect to Jeep with some OBD2 apps and see basic parameters.

    I will try to oder the recommended usb version of adapter and gove it a try.
    But it would be great if this will work as Android APP with the BT adaper. It would be just perfect!


    23. August 2015 17:49
    Works like a charm with chinese ELM327-USB! Cleared 5 engine + 5 transmission fault codes just in minutes. Luckily it seems that all codes were based on temporarily weak battery. Thanks!!!

    18. August 2015 20:46
    Thank you guys, the program works fine! :-)

    14. August 2015 11:11
    Thank you guys, the program works fine !
