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 sets after the PSCM experiences a momentary loss of vehicle voltage. Prior to shutting down, the PSCM stores data in memory, when the ignition is set to ON, the PSCM reads this data and if it is missing or corrupted, this DTC sets. Therefore, the presence of DTC U3001 means the loss of vehicle voltage occurred prior to the DTC being set. Consult the DTC Index for additional information if needed.
