Set Condition
WARNING: This page is about a different car, the 2014 Fiat 500e. However, it is still accessible from the selected car via links, so may be relevant.
The Battery Pack Control Module (BPCM) compares the radiator coolant temperature and battery pack coolant inlet temperature to the battery pack coolant outlet temperature. If the radiator and battery pack inlet temperatures are changing (±2° C over 5 minutes) and the battery pack coolant outlet temperature is not changing, or a comparison of the inlet, outlet and radiator temperatures are not within a calibrated range of each other, a DTC will set. The EVS lamp does not illuminate for this fault.
