Circuit/System Description
This is an internal fault detection of the drive motor generator power inverter module (PIM) assembly. This fault is handled inside the PIM and no external circuits are involved.
Conditions for Running the DTC
P0AEE, P0AF3, P0BD2, P0BD7, P0BDC, and P0BE1
• | Ignition ON after the ignition has been OFF for 6 hours. |
• | Temperature average of the inverter phase temperature sensors is greater than 12°C (10°F). |
• | Motor temperature sensor is greater than -40°C (-40°F). |
• | DTCs P0AEF, P0AF0, P0BD3, P0BD4, P0BDD, P0BDE, P0A2C, and P0A2D are not set. |
P0AEF, P0AF4, P0BD3, P0BD8, P0BDD, and P0BE2
Ignition ON.
P0AF0, P0AF5, P0BD4, P0BD9, P0BDE, and P0BE3
• | Motor temperature is greater than -40°C (-40°F). |
⇒ | If motor temperature is less than -40°C (-40°F) at Ignition ON, the drive motor must operate at greater than 20 N·m (14.75 lb ft) for a cumulative time of 1.5 minutes before the DTC will run. |
Conditions for Setting the DTC
P0AEE, P0AF3, P0BD2, P0BD7, P0BDC, and P0BE1
• | A 15°C ( 27°F) difference is observed between the individual inverter phase temperature sensor and the average of all the inverter phase temperatures. |
• | The above condition is present for 4 seconds. |
P0AEF, P0AF4, P0BD3, P0BD8, P0BDD, and P0BE2
The inverter phase temperature sensor is greater than 125°C (275°F) for 3 seconds.
P0AF0, P0AF5, P0BD4, P0BD9, P0BDE, and P0BE3
The inverter phase temperature sensor is less than -40°C (-40°F) for 3 seconds.
Action Taken When the DTC Sets
• | DTCs P0AEE, P0AEF, P0AF0, P0AF3, P0AF4, P0AF5, P0BD2, P0BD3, P0BD4, P0BD7, P0BD8, P0BD9, P0BDC, P0BDD, P0BDE, P0BE1, P0BE2 AND P0BE3 are Type B DTCs. |
• | The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays. |
Conditions for Clearing the DTC
DTCs P0AEE, P0AEF, P0AF0, P0AF3, P0AF4, P0AF5, P0BD2, P0BD3, P0BD4, P0BD7, P0BD8, P0BD9, P0BDC, P0BDD, P0BDE, P0BE1, P0BE2 AND P0BE3 are Type B DTCs.

Circuit/System Verification
- Clear the DTC information.
- Turn the ignition OFF for 1 minute.
- Operate the vehicle under the Conditions for Running the DTC.
- Retest for DTCs P0AEE, P0AEF, P0AF0, P0AF3, P0AF4, P0AF5, P0BD2, P0BD3, P0BD4, P0BD7, P0BD8, P0BD9, P0BDC, P0BDD, P0BDE, P0BE1, P0BE2 AND P0BE3.
Circuit/System Testing
Program the PIM with the latest software version and recheck for DTCs.
⇒ | If the DTC resets after programming or if the PIM already contains the latest software version, replace the PIM. |
