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.
The DTC sets when the PSCM receives invalid data from the SUMA. The data is likely invalid due to SUMA internal errors, damaged or inoperative sensors or components the SUMA 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.
