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 Jeep diagnostic 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 diagnostic software will never be sold for money, It is free forever – to everyone.
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 http://www.jeepswj.com/tips/ 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 Chinese BT and newer USB 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:
AT SP 5
You can ask about those commands from seller before buying Chinese ELM device. Chinese Vgate iCar2 iV350 BT and Vgate iCar3 BT devices were working in our tests, but we got feedback from customers that not all Vgate devices work. We asked about supported commands from Vgate, but they have really good skills of ignoring everyone who is asking something more specific. We will keep trying.
There are only a few places in EU where you can buy genuine ELM327 device. We found one from Romania and we bought one BT ELM327 device for testing. Now we can confirm that this device supports all necessary ELM commands and works fine with our software. Here is an image of this ELM327.
Same seller is also selling in ebay and his seller name is car.pulse

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.

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 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(www.elm-327.eu). 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?
8. septembre 2017 16:36

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.

15. February 2017 10:32
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.

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 !!!

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).

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.

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

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.

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!
