DTC P1E38

The power inverter motor, 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 earth.

Vehicle is ON or Charge Mode is active.

The control module does not detect voltage at the insulated gate bipolar transistor bias power supply.
