Go with JScan. Can't go wrong.What is the recommended code reader for the JL. I just had a check engine light come up a couple of days ago. Jeep is running fine though.
If you go the the JScan website they go into detail regarding the best OBD Bluetooth adapters for their product. More importantly also the ones that do not work well.The benefits of JSCAN are enormous compared to other "read only" scanners. JSCAN is an app for your phone and you'll need a way to wirelessly connect to your vehicle. Apparently, I have an outdated method. So, others can share the latest methods.
As mentioned in post 5, a BT OBD-II module is required when using JScan.Can I use it through my Bluetooth connection or do I still need a dongle or something else to plug in. The instructions seem to say that I can use Bluetooth. No wires needed. However, I tried connecting it and it doesn't seem to connect
