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

I1:

I2 - I3:

Normal Operation
With the key 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 traction battery control module (TBCM) monitors the current, voltage, temperature and leakage resistance of the 25 individual nickel metal hydride battery modules within the high voltage traction battery (HVTB). The TBCM also controls the contactors. DTC P0A1F is flagged if there are any internal errors of the HVTB caused by sensor failure, control module failure, or other severe related faults internal to the HVTB.

Possible Causes
- Service disconnect plug
- HVTB
