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. O1 : 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. CARRY OUT the steering angle sensor calibration procedure. REFER to PROGRAMMABLE PARAMETERS/STEERING WHEEL POSITION SENSOR CALIBRATION on the IDS and follow the calibration procedure.	CLEAR the DTCs. CARRY OUT the steering angle sensor calibration procedure.
