P1E38 – Auxiliary Transmission Fluid Pump Inverter Supply Voltage Circuit

P1E38 Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P1E38 Possible Causes

Program Power Inverter Module,Faulty Power Inverter Module,Power Inverter Module harness is open or shorted,Power Inverter Module circuit poor electrical connection

P1E38 Description

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.
