H4 RETRIEVE ANY DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST
Using a diagnostic scan tool, carry out the PCM self-test.
Are any Diagnostic Trouble Codes (DTCs) present in the PCM?
Yes | DIAGNOSE all PCM Diagnostic Trouble Codes (DTCs). REFER to: Electronic Engine Controls (303-14A Electronic Engine Controls - 2.3L EcoBoost (231kW/314PS), Diagnosis and Testing). REFER to: Electronic Engine Controls (303-14B Electronic Engine Controls - 3.7L Duratec (227kW/301PS), Diagnosis and Testing).

H5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0294:XX SET IN OTHER MODULES
Using the diagnostic scan tool, carry out the self-test for all modules. Retrieve and record the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0294:xx set in 1 or more modules in addition to the Moveable Roof Control Module A (MRCMA)?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new PCM.

H6 CHECK THE ELECTRICAL CONNECTORS
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
Ignition OFF. Disconnect Moveable Roof Control Module A (MRCMA) C4830. Disconnect GWM C2431. For 2.3L engine equipped vehicles, disconnect PCM C1551B. For 3.7L engine equipped vehicles, disconnect PCM C1381B. For 5.0L engine equipped vehicles, disconnect PCM C175B. Using a good light source, inspect each connector for the following:
corrosion - install new connector or terminal and clean the module pins damaged or bent pins - install new terminals or pins pushed-out pins - install new pins as necessary
Using a suitable mating terminal, check the following connector terminals for deformed or enlarged
