Before centering the Steering Angle Sensor technicians must first guide the vehicle wheel to direct straight ahead positioning. They should then use either a
Steering Column anti-rotation pin, a Steering Column lock, or a strap to keep the wheel steady before they begin work. Wheel rotation should be prevented to protect the sir system from damage. Steering column disconnection along with intermediate shaft(s) and steering gear operations must be performed without wheel rotation or tire movement to prevent sir coil assembly de-centering. Prior to sensor removal the technician must properly identify the Steering Angle Sensor type and place the connector to face right from their front view position. Reusing the existing sensor eliminates the requirement for centering procedures. Lift out both the adapter and the bearing assembly's sensor and its connector. Installation requires bringing the sensor into alignment with the
Steering Shaft and correctly connecting the connector. Prior to sensor installation you should perform alignment of marked surfaces on either the flush rotor flange cuff or on the raised rotor flange cuff then maintain this position until the sensor reaches its final position. When installing a new sensor you must wait until the installation is complete before removing the pin. The sensor requires careful installation where installers need to identify three features: pin holes for centering and alignment marks and foam rings. Maintain the exact operating sequence for every sensor type while keeping sensors aligned correctly from setup to deployment.
