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 does not receive the TCCM messages within a certain time frame.

This can occur if the TCCM wiring harness or electrical connectors are loose or damaged, or if the vehicle battery state of charge levels are low. Consult the DTC Index for additional information if needed.
