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掳C (10掳F).

* Motor temperature sensor is greater than -40掳C (-40掳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

* Ignition ON.

* Motor temperature is greater than -40掳C (-40掳F).

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.
