P2BC7Battery Charging System Positive Contactor B Control Circuit/Open

P2BC7 indicates that the powertrain control module (PCM) has detected an open circuit or loss of control on the positive contactor control circuit for the battery charging system. The PCM commands the contactor to close or open, but the expected voltage or current feedback on the control wire does not match, so it sets this code and may disable charging or isolate the high-voltage battery.
