Been using WJdiag Pro – Diagnostics for J for a couple months now. It’s basically an app that helps you diagnose issues with your Jeep Grand Cherokee from 2002-2004. Pretty solid if you’re into maintaining your Jeep.
Here’s what you can do – you connect the app to your car via a Bluetooth OBD2 adapter, and it’ll pull all kinds of diagnostic info. There’s also a tutorial page that shows you how to use the different features. It’s got stuff like reading error codes, checking sensor data, and even resetting certain modules. Took me a while to figure out some of the more advanced stuff, but it’s really handy once you get the hang of it.
Look, if you’ve got an older WJ/WG Jeep, you’ll probably find this app really useful. It’s not perfect – the UI could be a bit more polished and the Bluetooth connection can be finicky at times. But overall it does the job and helps you keep your Jeep running in tip-top shape.
