Steering Angle Sensor Centering

WARNING: An inaccurate or not centered steering angle sensor could limit the operation of the electric power steering and may result in personal injury.

NOTE: The GDS2 calibration software must be updated to the latest diagnostic package for the scan tool Reset and Learn functions to work correctly.

The external, column mounted, steering angle sensor does not require a centering often. Centering of the external steering angle sensor might be required after certain service procedures are performed. Some of these procedures are as follows:

Wheel alignment
Steering gear replacement
Steering column replacement
Steering angle sensor replacement
Collision or other physical damage
Electronic brake control module (EBCM) replacement

The external steering angle sensor centering procedure can be completed with a scan tool using the following steps:

Using the steering wheel, align the front wheels forward.
Apply the parking brake or set the transmission in the Park.
Install the scan tool to the data link connector.
Ignition ON, engine OFF
Select Steering Wheel Angle Sensor Reset in the Steering Wheel Angle Sensor Module Configuration/Reset Functions list.
NOTE: If installing a new steering angle sensor, the Reset function is not required. Proceed to step 7. Reset function only needs to be performed when using a vehicles existing steering angle sensor.
Follow the scan tool directions to complete the reset procedure.
Select Steering Wheel Angle Sensor Learn in the Steering Wheel Angle Sensor Module Configuration/Reset Functions list.
Follow the scan tool directions to complete the learn procedure.
Select Steering Wheel Angle Sensor Learn in the Electronic Brake Control Module Configuration/Reset Functions list.
Follow the scan tool directions to complete the learn procedure.
If the vehicle is equipped with RPO NJ1 electronic power steering, perform the Software Endstop Learning procedure. Refer to Power Steering Control Module Calibration .
Clear any DTCs that may be set.
