PINPOINT TEST L: DTC P0A1F - BATTERY ENERGY CONTROL MODULE HAS INTERNAL ERRORS

Normal Operation

With the ignition switch in the ON position and the engine ON or OFF (the engine must have run at least once after the key was cycled to ON), the battery control module (BCM) monitors the current, voltage, temperature and leakage resistance of the 50 individual nickel metal hydride battery modules within the high-voltage traction battery (HVTB). The BCM also controls the contactors.
