U057DInvalid Data Received From Off-Board Charger Control Module
- Generic OBD-II code · Network
- How the car detects it
- Despite its name, the off-board charger control module sits inside the vehicle: it conducts the dialogue with an external DC fast charger, which under CCS runs as power line communication on the control pilot contact (ISO 15118, DIN 70121) and under CHAdeMO over a CAN link in the connector. Ford calls this unit the off-board charger controller (OBCC) on the Mustang Mach-E and E-Transit; SSM 50923 had new OBCC software fix interrupted DC fast charging at some EVgo stations. U057D is stored when another module in the car receives frames from this controller but rejects them, for instance because of a wrong counter, a failed checksum or implausible values. No manufacturer documents U057D itself. DC fast charging is likely to stop or refuse to start, while AC charging normally still works.
