Circuit/System Description

The power inverter module, 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 inverter temperature sensor is part of the power inverter module and is not serviced separately.
