P1Ec4: Your Car’s Battery Is In Trouble
The P1EC4 code refers to a problem with the hybridEV battery pack heater transistor. The hybridEV battery contains 5 high voltage contactors and 2 transistors.
The high voltage contactors and transistors 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 2 transistors consist of the precharge transistor and heater transistor. The contactors and transistors close and open in a specific sequence controlled by the hybridEV powertrain control module 2. The hybridEV powertrain control module 2 supplies voltage to the control circuit for the high voltage contactorstransistors.
Ground is provided through the case ground.
