corrosion (install new connector or terminals – clean module pins) damaged or bent pins – install new terminals/pins pushed-out pins – install new pins as necessary
Reconnect the PCM connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
Is the concern still present?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new PCM. For 2.3L, REFER to: Powertrain Control Module (PCM) (303-14A Electronic Engine Controls - 2.3L EcoBoost (231kW/314PS), Removal and Installation). | |
