WARNING: This page is about a different car, the 2009 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
The power steering control module (PSCM) is serviced separately from the steering column assembly. If the power steering control module (PSCM) is replaced, the Steering Position/Torque Sensor Calibration must be performed.
