Note: The power steering control module is serviced separately from the steering column assembly.

If the Power Steering Control Module is replaced, the following procedures must be performed in the following order:

1. 1. PSCM reprogramming, refer to Service Programming System (SPS)
2. 2. Steering Position/Torque Sensor Calibration

Note: The power steering motor is serviced separately from the steering column assembly. However, the torque sensor is serviced as part of the steering column assembly.

After replacing either the steering column assembly or the power steering motor only the Steering Position/Torque Sensor Calibration procedure must be performed. Certain steering symptoms can be corrected by performing the Steering Position/Torque Sensor Calibration procedure such as:

1. Install the scan tool.
2. Turn ON the ignition, with the engine ON
3. With the scan tool select Special Functions
4. Select Steering Position/Torque Sensor Calibration and press the Enter key
5. Center the steering wheel
6. Turn OFF the ignition and remove the key from the ignition cylinder
7. Wait 20 seconds and turn ON the ignition, with the engine OFF
8. Turn the steering wheel 180 degrees to the left and hold
9. Turn the steering wheel 180 degrees past center to the right and hold

Note: After centering the steering wheel, remove hands and other objects from the steering wheel and ensure the suspension is relaxed and no bias, or uneven force is being applied to the steering system

10. Center the steering wheel
11. Wait until the scan tool screen displays ‘Calibration Complete’. If the scan tool displays ‘Procedure Failed’, repeat the calibration procedure
12. Press the exit key. Verify there is no uneven steering feel by turning the steering wheel from left to right. If the steering feel seems uneven as the steering wheel is turned in either direction, repeat the calibration procedure
13. Use the scan tool in order to clear any PSCM DTCs

Note: After turning OFF the ignition, allow 25 seconds of wait time before performing any procedures that require the vehicles battery to be disconnected, or module memory loss may occur

14. Turn OFF the ignition
