DTC Trigger

WARNING: This page is about a different car, the 2020 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

This DTC sets in other modules when those modules do not receive messages from the PSCM within a certain time limit. This can occur if the vehicle wiring harness wires or connections, connectors or pins between the PSCM and other modules are loose or damaged. This DTC also sets if the PSCM is not communicating on the vehicle CAN due to an internal fault condition or a low battery state of charge. Consult the DTC Chart for additional information.
