DTC Trigger

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2022 Lincoln Navigator, 2022 Lincoln Nautilus, 2022 Lincoln Corsair, 2022 Lincoln Aviator, and 2022 Ford Transit-350 HD. 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 TCCM. The data is likely invalid due to TCCM internal errors, damaged or inoperative sensors or components the TCCM 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.
