DTC Trigger

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2021 Lincoln Corsair, 2021 Lincoln Aviator, 2021 Ford Transit-350 HD, 2021 Ford Transit-350, and 2021 Ford Transit-250. However, it is still accessible from the selected car via links, so may be relevant.

This DTC occurs when other modules do not receive the PSCM messages within a certain time frame. This can occur if the PSCM wiring harness or electrical connectors are loose or damaged, or if the vehicle battery state of charge levels are too low for the PSCM to initialize and power up in time to communicate with the other modules. Consult the DTC Index for additional information if needed.
