IMPORTANT:
Since there is no steering assist while performing this procedure, the procedure might be easier to accomplish if the vehicle is raised slightly off the ground using a hoist. Follow all on-screen instructions displayed on the scan tool in order of appearance.
- Install the scan tool.
- Engine ON.
- With the scan tool select Chassis, Power Steering Control Module and then Special Functions.
- Center the steering wheel.
- Turn the steering wheel 90 degrees from center to the right, and 90 degrees from center to the left, return the steering wheel to center.
- With the steering wheel centered, remove hands from the steering wheel and then press the calibrate key. The steering wheel may vibrate slightly for approximately 2-3 seconds.
- Wait until the scan tool screen displays "Calibration Complete". If the scan tool displays "Procedure Incomplete", repeat the calibration procedure.
- 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.
- Use the scan tool in order to clear any PSCM DTCs.
- Turn OFF the ignition.
IMPORTANT:
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.
IMPORTANT:
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.
