DTC Trigger
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets when the PSCM does not receive the RCM messages within a certain time frame. This can occur if the RCM wiring harness or electrical connectors are loose or damaged, or if the vehicle battery state of charge levels are low. Consult the DTC Index for additional information if needed.
