P2BCCBattery Charging System Negative Contactor B Stuck Closed

P2BCC indicates that the battery charging system's negative contactor B is stuck in the closed position, meaning the control module has commanded the contactor to open but the circuit remains continuous. The computer detects this by monitoring the contactor's feedback circuit and seeing voltage or current that should not be present when the contactor is supposed to be open.
