DTC Trigger

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.
