DTC Trigger

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2019 Ford Expedition, 2018 Lincoln MKZ, 2018 Ford Transit-350 HD, 2018 Ford Transit-350, and 2018 Ford Transit-250. However, it is still accessible from the selected car via links, so may be relevant.

This DTC occurs when the PSCM does not receive the PCM messages within a certain time frame. This can occur if the PCM 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.
