WJdiag Tutorial - Jeep Grand Cherokee P0702 FIX

Thank you for using WJdiag diagnostic application.
WJdiag is made for diagnosing issues on Jeep Grand Cherokee 2002-2004 year, WJ/WG models. On 2.7 CRD Jeep model are supported all electronic modules that car have. On gasoline and 3.1 diesel model are supported all electronic modules except Engine and Transmission.
In addition WJdiag can access to many Chrysler Group cars (officially untested) made between 1998 and 2005.

WJdiag is software application and for diagnosing Jeep Grand Cherokee 2002-2005, but it works fine with many Chrysler Group cars made between 1998-2005 as well. WJdiag needs Bluetooth ELM327 diagnostic device. There are many fake ELM327 devices on the market that costs 5…30 EUR, but you should be aware to buy fake ELM327 device, because they may not work correctly. Some of fake ELM327 devices are working, but if you buy fake device, then you never know, will it work or not. We recommend to use ELM327 with GENUINE CHIP made by ELM ELECTRONICS. With genuine ELM devices you can be sure that it is compatible as promised.

There are Basic and Pro versions of WJdiag available. Basic version is free and it have most important functions only: you can READ and CLEAR Engine and Transmission fault codes on 2.7 CRD model. You can also view generic data of other electronic modules like part number, software version, year released etc., but all other data is limited.
With Pro version you will have full opportunities that WJdiag offers – full access to every electronic module, fault codes reading/clearing, Live Data with logging, Input/output values and some coding options.

Before installing WJdiag be sure that you have uninstalled previous versions. Before you buy Pro version, please test your ELM327 device with Basic version. If you can access to engine, transmission and can see generic data of other modules, then your ELM327 is compatible with your Jeep Grand Cherokee. Engine and Transmission of the Jeep 2.7 CRD are using K-Line data bus for diagnostic device, all other electronic modules are using J1850 data bus.

If WJdiag is installed, then you must pair ELM327 diagnostic device through Bluetooth (if it is not already paired). Pairing code for ELM327 devices are usually 1234, you can get correct code from your ELM327 seller. Pairing must be done only once, after successful pairing ELM327 will be remembered by Android.
After opening WJdiag you should connect your ELM327 device. If you have several Bluetooth devices paired with your Android phone/tablet, then list of your paired devices will shown up. Choose correct device and connect it. Engine must be on idle or ignition key must be turned to ON (dashboard lights like battery, oil are lighting and gauges are up).
You will see list of modules that Jeep Grand Cherokees have. This list does not show modules your car exactly have, it is full list that Jeep GC can have. On this list WJdiag is connected with ELM327 device, but not connected with your car. Equipment of your car depends of modules your car have released by factory. Choose module with what you like to work and WJdiag will connect with your car.
If your car have current module, then you will see 4 lines: Fault codes, Sensor Live Data, Input / Output display, Misc / Tests.
By choosing Fault Codes you will see what fault codes or fault explanations are stored in current module and can clear them. Engine and Transmission have Freeze Frame information of every fault code, push to current fault and you will see more specific data about code: times occurred, active/stored etc.

Sensor Live Data will show actual values of current module. There is list of values, on right side select values you like to see and push “Show selected” on top of the screen.
Selected values will shown up on next screen. The more values you choose, the more slowly they are exchanged. Default time between requests is 500ms and it means that if you choose single value, then it will updated after every 500ms and if you choose 2 values, then total refresh time is 1000ms. You can choose this time from application settings, check at end of this tutorial.

Input / Output Display is very similar with Live Data, but it show positions and values of switches, relays etc.

Misc / Tests is for special functions like injector test and coding or speedometer correction coding. On this image is shown injector feedback values. For example injector test: if values are equal, then injectors are fine, if values are unequal, then injectors are not good. Perfect value is if all 5 injectors are on zero.
ABS Pinion Factor coding is made for speedometer correction. For example if you changed tires with larger ones, then speedometer will show incorrect speed. With Pinion Factor coding you can choose how many rotations your wheels are making per one mile.

Main menu.

Livedata records.
If Live Data logging is enabled, then here you can see log files. Log files are in table format and you can view them if you have excel viewer installed. Excel viewer is not included with WJdiag and you need to install it separately. You can also download log files to your computer and view them with Microsoft Excel, Mozilla OpenOffice or with some other table viewer. Log files location in your Android device is Internal shared storage/WJdiag folder.

Slider button NO LIVEDATE RECORDS / LIVEDATA RECORDS.
Here you can enable and disable Live Data logging.
Next 3 slider buttons are for Metric / Imperial system selecting. Application will convert Live Data values to choosed system.

Livedata and In/Out delay.
Depending on the diagnostic procedure you may need to see Live Data and Input / Output values with different refresh rate. 0 ms delay means that application will send next query as soon as answer for previous request is received. With increasing delay you can choose how much time application will wait until new request. Maximum delay can be 10 second. Be mentioned that some ELM327 devices can not handle with high speed and can jam. In such case increase delay until your ELM327 will stable. If you select several values on Live Data display, then every request will have delay.
If you need to monitor some values with minimum delay, then check them one by one.

Submenus.

After you choose some module from main menu, WJdiag will send some basic requests to current module and show results. On this tutorial is selected Engine.

On top side you can see some ECM basic data like engine model, VIN code, model year and part number. Depends of current module, part data may be more or less.

Bottom of the basic data is submenu of current module:
Fault codes
Sensor Live Data
Input / Output display
Misc / Tests
There are always 4 lines on all submenus and supported functions are white color. If some module does not support all functions, then unsupported function is grey and you can not choose it.

Fault codes: you can read and clear fault codes of current module. In addition to the error codes ECM (Engine Control Module) allows you check Freeze Frame as well.
Sensor Live Data: you can see actual values of each sensor and store values to file with delay 100ms to 10 seconds.
Input Output Display: you can see positions of different valves and chokes.

Misc / Tests: you can activate various processes, make tests and encode components.

Fault codes.

On top of fault codes page you can see module you are currently diagnosing, here in picture it is ECM.

On next line you can clear all fault codes. If some fault code can not be cleared, then it means that fault is active. WJdiag actually clears all faults, but active fault may appear back straight after clearing and for user seems that fault is not cleared. Some fault may appear back after some time. For example only with warm engine or cones back after the shock.Some fault codes may be old and inactive, for example broken part is already replaced, but fault code is not cleared. Those fault codes are not coming back after clearing as problem is fixed.We recommend clear fault codes, drive until problem appears back and check fault codes again. In this case you will see what is actually broken and will not waste your time and money for old fault.To see more information about fault, press to current fault and Freeze Frame, more specific data will appear.

Freeze Frame

Freeze Frame is available only for ECM module. Freeze Frame data will be stored on moment when DTC was detected.
After you press to specific fault from codes list, ECM will show Freeze Frame data. Freeze Frame data will help you to examine problem more deeply than just number and explanation.
On first line are Back button and module you are diagnosing.
Second line is current fault code and major explanation of the fault.
On third line is subfault, more specific explanation about problem.
Next lines are basic Freeze Frame data:
Defect – Problem can be Stored (old, inactive fault) or Active fault.
Freq – Total times fault appears
RPM – Engine RPM
Qty – Fault appears from last start
ECT – Engine temperature
Battery – Battery voltage

Live Data

With Live Data can checked values of the sensors and make log files for examining.
Logging can be activated on settings page move slider to “Livedata records” and choose log interval from Livedata and In/Out delay. Log files will be stored in table format and can be viewed with Microsoft Excel, Mozilla OpenOffice or with some other table viewer.

On Live Data menu are sensor names and on right side are check boxes for activating sensor value viewing.

After sensor(s) are selected, press “Show selected” from top of the screen and current values will be shown.
Default data request speed is 500ms and it can be changed from WJdiag settings page. 500ms delay means that WJdiag will wait 500 millisecond between requests. If there are more than one value selected, then WJdiag will wait 500ms between each request. For example checking single sensor with 500ms delay, then theoretically new value of current sensor will updated twice in every second. If checking 10 values simultaneously, then each sensor value will be updated after 5 seconds.
In addition to the user user-selected delay, there is also request sending and receiving time: WJdiag is sending request through phone to ELM327>ELM327 sending request to car>car sending answer to ELM327>ELM327 sending answer to phone/WJdiag. Depends of current ELM327 quality, this time may be about 30…200ms.
Some ELM327 may jam with short request delay, in this case longer delay should be used.

Input / Output

With Input / Output monitor can checked signals and controls of switches, relays, solenoids etc. and make log files for examining.

Logging can be activated on settings page move slider to “Livedata records” and choose log interval from Livedata and In/Out delay. Log files will be stored in table format and can be viewed with Microsoft Excel, Mozilla OpenOffice or with some other table viewer.

On Input / Output monitor menu are signals and controls names and on right side are check boxes for activating data viewing.

After checkbox(es) are selected, press “Show selected” from top of the screen and current values will be shown.

Misc / Tests

Miscellaneous functions are for coding procedures and adjustments like adding remotes and keys, injector coding, odometer correction, ABS bleeding etc.

Actuator tests provide the capability to activate vehicle system components to check electrical and mechanical operation. After they are started, the actuator tests continue until user cancel test or ignition is switched to OFF position.

Some test is simple “switch ON/OFF” based, some need specific sequence of actions, please follow all instructions during tests/codings. We highly recommend to use ELM327 devices with genuine chip, made by ELM Electronics from Canada and avoid devices with fake chip. If fake ELM327 fails during changing vehicle adjustments, then it may damage control unit.Here are shown possibilities of modules, one by one.

Engine Miscellaneous and Tests

ECM Tests	Test explanation
Fuel Correction Test	Fuel correction test shows how good or bad injectors are, it measuring RPM and fuel correction of each cylinder. 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. Please note that measuring can be made between 600...1800 RPM. With higher RPM, ECM will not send any information anymore.
Injector Learn	Injectors have numbers 1, 2 and 3 stamped from industry and engine should be coded by those numbers. If car is used already, then matching with stamped numbers does not have point anymore, because injectors are already worn out. For used injectors more important is to compare fuel consumption with different numbers and choose number that needs less correction for each injector (+ - values in injector test) and with what numbers fuel consumption is smallest. With changing those numbers and comparing fuel consumption from Overhead Console, you can make engine run smoother and reduce fuel consumption up to few liters per 100 km.
