Each drive motor generator is controlled by a motor control module (MCM). The MCM constantly monitors the requested torque and the delivered torque of its respective drive motor generator.

The MCM has detected that drive motor generator torque is not being delivered as expected.

DTC P0C1A is a Type A DTC.

Because the drive axle and drive motor 2 are joined mechanically through a planetary gear set, a drive axle condition that requires drive motor generator 2 to utilize excessive current while trying to rotate the drive axle may cause this DTC to set.

2. Repair the following conditions if observed:

Important: If a seized or binding drive axle is observed, internal transmission damage may have occurred.

•	Seized or binding drive axle

•	Seized or binding transfer case (4 wheel drive option)

•	Seized or binding braking system

3. Drive the vehicle, retest for DTC P0C1A.
