瀚慖f motor temperature is less than -40掳C (-40掳F) at Ignition ON, the drive motor must operate at greater than 20 Nm (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掳C ( 27掳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

Circuit/System Verification
1. Clear the DTC information.
2. Ignition OFF for 1 minute.
3. Operate the vehicle under the Conditions for Running the DTC.
4. Retest for DTCs P0AEE, P0AEF, P0AF0, P0AF3, P0AF4, P0AF5, P0BD2, P0BD3, P0BD4, P0BD7, P0BD8, P0BD9, P0BDC, P0BDD,
