The issue with this Jeep is that the alternator would not charge the battery. We tired a few junkyard alternators and they did not fix the issue. Traced the problem back to the PCM as it was not giving the signal to the alternator to start charging. We got a used PCM for it but it needed to be VIN matched to the vehicle for the red security light to go off and the rest of the modules to be able to communicate with it. This Launch scan tool worked great and was easy to flash the new VIN to the used PCM.
