The P1EC6 code refers to the performance of the hybridEV battery pack heater. The hybridEV battery contains 5 high-voltage contactors and 2 transistors.

The high-voltage contactors allow the high-voltage DC batteries to be connected to the vehicle or safely contain the high-voltage DC within the hybridEV battery assembly.

The hybridEV battery pack coolant heater is mounted to the coolant inlet on the back side of the hybridEV battery contactor assembly.

The hybridEV powertrain control module 2 monitors the temperature change at the hybridEV battery pack coolant temperature sensor 1 to determine if the hybridEV battery pack coolant heater is functioning properly.
