WJdiag Pro - Diagnostics for Jeep Grand Cherokee
WJdiag is working with Bluetooth ELM327 device through OBD2.
Supported functions of WJdiag Pro are listed on our website tutorial page at https://jeepswj.com/wjdiag-tutorial
We highly recommend to use good ELM327 and avoid fake Chinese devices.
Most of 10 EUR Chinese ELM327 devices do not support ISO 9141-2 and J1850 data protocols that are needed for Jeep WJ diagnostic and will display connection error even if some other generic diagnostic app can connect to some module.
WJdiag is customized app for Jeep WJ/WG, it can not connect with your car if your ELM327 can not handle data that Jeep needs. There are no problems with good ELM327 devices and they can connect to car correctly. Your ELM327 compatibility can be checked with WJdiag Free.
WJdiag has all options of professional car diagnostic - Fault Codes, Sensor Live Data, Tests and Coding. All electronic modules that 2.7 CRD Jeep has are supported. All electronic modules except Engine, Transmission and Shifter are supported on gasoline and 3.1 diesel model.

Hello! I have alredy purchased this app, it's a really great thing. Just have some questions - is it possible with the app to learn new keys (immo) and remote? And I can't found the option "brake bleeding". Where us it in menu? Maybe I have not the original ELM.
The only real alternative to a DRB III for the Jeep GC 2.7 CRD. Developer support is first class. Thank you for continued improvements. App has paid for itself many times already.
Excellent, got the car out of limp mode which the RAC couldnt! Life saver, saved big cost as guy said it needed new transmission, All it turned out to be is a low battery put it into limp
great app perfect for the 2.7 crd gives me access to all the information I needed on the gearbox and being able to reset the codes after installing my new conductor plate as other apps do not connect to the jeep
Free version tells you you need pro version. Pro version then tells you can't connect.
Worked really well then I had to get a new phone.cloned the app to new phone now won't connect and I'm not going to pay for another one.so please fix this problem.
It's an amazing tool to have, the actuator tests update is another big leap forward
Hi there it didnt seem to work and yet it does on other apps for my wj I wish it did work but it wouldnt hook up to elm 327
It doesn't work with a gas engine. Bummer because this would be a great app!!!
The apps is for only Jeep Grand Cherokee 2.7 crd, WG, 2001-2004! It may not work for jeeps wj!
Fantastic App! Thank you so much for creating it 👍🏼
Bought too fast no engine support for 4.7 Some free app do so ?? My bad its clearly stated in info of app
Great app, easy to use. One question, is it possible to program the RKE with the app?
Saved me a few times now great app!
Excelent. app, very helpfull for WJ 2.7crd. When will next release with RKE programming be available?
Great app. Big money saver.
Great app, helped me a lot.
used as beta now bought. its a must have for wj owners
Good app for Jeep WJ CRD owners
Be lost without it
If you have a WJ 2.7 you NEED this app. Only runs on android which is a bit of a pain being an Apple user, but you can get cheap android devices/phones to run it. After five years of pulling my hair out at not being able to diagnose issues, beyond doing the "old three key dash routine" (which tells you very little). And very few workshops (in Australia at least) have software to diagnose 2.7's. Get it! You won't regret it. Faults, live data across every key function you are likely to need. And great support.
