Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) — 2016 workshop reference 3554

Reconnect all FCIM 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 FCIM. Refer to the appropriate section in Group 415 for the procedure.
No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.

G18 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

Disconnect and inspect all PCM connectors. Repair:

corrosion (replace connector or terminals – clean module pins) damaged or bent pins – replace terminals/pins pushed-out pins – replace pins as necessary

Reconnect all PCM connectors. Make sure they seat and latch correctly. Operate the system and verify 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). For 3.7L, REFER to: Powertrain Control Module (PCM) (303-14B Electronic Engine Controls - 3.7L Duratec (227kW/301PS), Removal and Installation). For 5.0L, REFER to: Powertrain Control Module (PCM) (303-14C Electronic Engine Controls - 5.0L 32V Ti-VCT/5.0L Ti-VCT V8 (308kW/418PS), Removal and Installation). For 5.2L, REFER to: Powertrain Control Module (PCM) (303-14D Electronic Engine Controls - 5.2L 32V Ti-VCT, Removal and Installation).
No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
