P2BC8Battery Charging System Positive Contactor B Control Circuit Range/Performance

P2BC8 indicates that the battery charging system's positive contactor control circuit, specifically the 'B' circuit, is reporting a range or performance error to the powertrain control module. The computer has detected that the voltage or current on the control circuit for the positive contactor is outside the expected range during commanded operation, which can prevent the high-voltage battery from charging or discharging properly.
