DTC Descriptor
DTC P1E15
- Drive Motor 1 Control Module 5 Volt Reference 1 Circuit

DTC P1E16
- Drive Motor 1 Control Module 5 Volt Reference 2 Circuit

DTC P1E17
- Drive Motor 2 Control Module 5 Volt Reference 1 Circuit

DTC P1E18
- Auxiliary Transmission Fluid Pump Control Module 5 Volt Reference Circuit

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. Each motor control module utilizes a 5 V reference power supply for internal circuit needs. This fault is handled inside the power inverter module and no external circuits are involved. The motor control modules and the hybrid powertrain control module are part of the power inverter module and are not serviced separately.

Conditions for Running the DTC

* The vehicle is ON.
* The system voltage is at least 7 V.

Conditions for Setting the DTC

The control module has detected an internal malfunction.
