WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

CARRY OUT a self-test of the PCM. If the scan tool indicates that the module is not responding, REFER to COMMUNICATIONS NETWORK to diagnose the network communication concern. If PCM DTCs are present, REFER to the ENGINE CONTROLS - POWERTRAIN DTC CHARTS & DESCRIPTIONS (EXCEPT DIESEL & HYBRID) or for Hybrid, refer to ENGINE CONTROLS - POWERTRAIN DTC CHARTS AND DESCRIPTIONS (HYBRID) to diagnose the PCM.
