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.

The DTC sets when the PSCM receives invalid data from the FCIM. The data is likely invalid due to FCIM internal errors, damaged or inoperative sensors or components the FCIM uses to gather vehicle data. The invalid data DTC is not set due to the PSCM, PSCM wiring or connectors. Consult the DTC index for additional information if needed.
