DTC Trigger
WARNING: This page is about a different car, the 2019 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets when the PSCM internal self tests detect a software or hardware internal error. This can be due to internal faults in the PSCM or from water getting inside the PSCM from damaged or cracked housings, or torn bellows boots. For additional fault setting information, refer to the PSCM DTC Chart.
