Just found this thread from the AusJeep site (have registered but awaiting admin permission to post).....
Starts off in different direction, but then...... it is almost identical issue to mine....same fault codes (they have a few more than ours) they go through same process.... get ECU (PCM) tested as okay but doesn't rectify faults.... end up buying new one....solves problem!!
Any thoughts? Appreciate its a long one to read
Theres no way I'll stick a new ECU on...just not worth it. Anyone here able to flash a second hand one /know a way around fitting one?
