DTC codes / P2Bxx · Hybrid propulsion / P2BCE
P2BCE indicates that the battery charging system's negative contactor control circuit is open, meaning the powertrain control module (PCM) has detected an interruption in the electrical path that commands the negative-side contactor to close. This contactor is part of the high-voltage battery pack's safety system, and an open circuit prevents the PCM from properly controlling the connection between the battery's negative terminal and the rest of the high-voltage system.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
