Code P1E08 Saturn Description

The hybrid powertrain control module monitors the hybrid/EV battery high voltage contactor status and requests contactor function primarily via serial data. In the event of a serial data fault there is a redundant discreet circuit between the two controllers that transmits the hybrid powertrain control module contactor requests to the hybrid powertrain control module 2 via a pulse width modulated (PWM) signal. The hybrid powertrain control module is internal to the power inverter module, often referred to as the drive motor generator power inverter module, and is not serviced separately.
