Normal Operation

The PSCM continually monitors and adjusts steering efforts based on the torque sensor inputs to enhance feel of the steering system. Compensation is made to reduce the effect of pull or drift that may be experienced when driving on roads with a high degree of camber. If the level of compensation required to keep the vehicle driving straight ahead exceeds a pre set level a DTC will be set.

1. T1: VISUAL INSPECTION 

   Carry out a visual inspection.

   • Check for even tire sizes and pressures as per the manufacturer's specification.
   • Check for uneven tire wear.
   • Check the outer tie rod ends and suspension ball joints for impeded movement.
   • Verify that the steering column shaft rotates freely and is not grounded against other vehicle components.
   • Check the steering gear for correct installation, tight spots and uneven operation.
   • Check the steering and suspension for bent or damaged components.
   • Check the steering and suspension geometry.

   Has a concern been identified? 

   Yes	No
   REPAIR the concern identified during the visual inspection. CLEAR the DTCs. Using a diagnostic scan tool, RESET the compensation value for the pull/drift compensation function and the compensation value for the steering straight ahead position. TEST the system for normal operation.	CLEAR the DTCs.
