Circuit/System Description

The power steering control module monitors the steering angle sensor signal via the GMLAN serial data circuit. The power steering control module utilizes this signal to determine a center point for Active Return and Soft End Stops. Upon detecting an invalid steering angle sensor signal, the power steering control module will disable Active Return and Soft End Stops, then set a DTC.

NOTE:

To most drivers the loss of Active Return and Soft End Stops may not be noticeable as there is no visual indicator activated on the instrument cluster or driver information display.

There is no diagnosable cause with the power steering control module when this DTC is set, DO NOT REPLACE POWER STEERING CONTROL MODULE OR STEERING GEAR DUE TO THIS DTC.

For diagnosis of an invalid steering angle sensor signal, refer to DTC C0710 also diagnosis in Antilock Brake System.
