Power Steering Control Module (PSCM) Setup

After replacing the power steering motor and module assembly the following 3 procedures must be performed. After replacing the steering column assembly only the steering position sensor and the torque sensor calibration procedures must be performed. The steering position sensor and torque sensor calibration procedures should also be performed after a suspension alignment. Certain steering symptoms can be corrected by performing the steering position sensor and torque sensor calibration procedures such as:

* Poor, or uneven return to center
* Poor, or uneven on center feel
