Power Steering Control Module (PSCM) Setup

2006 Pontiac G6 GTP, 2D Coupe, StandardSECTION 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
IMPORTANT: The power steering control module (PSCM) must be setup using the service programming system (SPS). There are 8 different tuning profile calibrations stored in the PSCM. The SPS will select the correct tuning profile calibration for this vehicle. Setup the PSCM to use that profile. If the PSCM has not been setup, the scan tool will display the Tuning Profile is 0 in the EPS data list, and DTC C0551 will set.
