DTC Descriptors
DTC P150D
- Supply Voltage Circuit 2 Low Voltage

DTC P150E
- Supply Voltage Circuit 1 Low Voltage

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 drive motor generator 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 drive motor generator 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

P150D

Battery voltage on circuit 2 is less than 8.0 V for more than 2.5 seconds.

P150E

Battery voltage on circuit 1 is less than 8.0 V for more than 2.5 seconds.

Action Taken When the DTC Sets

DTC P150D and P150E are Type C DTCs.

Conditions for Clearing the DTC

DTC P150D and P150E are Type C DTCs.

Circuit/System Verification

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.

DTC P150D
1. Vehicle OFF, disconnect the X1 harness connector at the T6 power inverter module.
2. Vehicle ON, verify greater than 12.0 V at terminal 24.

• If less than the specified range, test the circuit for a short to ground or an open/high resistance.

3. If the circuit tests normal, program the T6 power inverter module. If the DTC resets, replace the T6 power inverter module.

DTC P150E
1. Vehicle OFF, disconnect the X2 harness connector at the T6 power inverter module.
2. Vehicle ON, verify greater than 12.0 V at terminal 35.

• If less than the specified range, test the circuit for a short to ground or an open/high resistance.

3. If the circuit tests normal, program the T6 power inverter module. If the DTC resets, replace the T6 power inverter module.
