Code P1EBF Saturn Description

The hybrid/EV 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 hybrid/EV battery assembly. The 5 high voltage contactors consist of a main positive high voltage contactor, main negative high voltage contactor, charge positive high voltage contactor, charge negative high voltage contactor and multi-function high voltage contactor. 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 hybrid/EV powertrain control module 2. The hybrid/EV powertrain control module 2 supplies voltage to the control circuit for the high voltage contactors/transistors. Ground is provided through the case ground.
