WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
The power inverter motor, often referred to as the drive motor generator power inverter module, contains two motor control modules and the hybrid/EV powertrain control module 1. The two motor control modules operate their respective drive motor based upon power inverter module commands. The hybrid/EV powertrain control module 1 controls the auxiliary transmission fluid pump. The hybrid/EV powertrain control module 1 and the motor control modules share the power inverter module ignition voltage circuit, battery voltage circuits and chassis ground.
