Circuit/System Description

The power inverter module, often referred to as the drive motor generator power inverter module, contains three motor control modules and the hybrid powertrain control module. Two of the motor control modules operate their respective drive motor generator based upon power inverter module commands. The third motor control module controls the auxiliary transmission fluid pump motor. The hybrid powertrain control module and the motor control modules share the power inverter module ignition voltage circuit, battery voltage circuits and chassis ground.

Conditions for Running the DTC

The Vehicle is ON.

Conditions for Setting the DTC

Circuit/System Verification

1. Verify that DTC P0562 or P0563 is not set.

• If DTC P0562 or P0563 is set, refer to DTC B1325, B1330, B1517, C0800, C0899, C0900, C12E1, C12E2, P0562, P0563, P1A0C, P1A0D, or P1EFC B1325.

2. If the DTC is set, program the T6 power inverter module. If the DTC resets, replace the T6 power inverter module.
