The sir system must be disabled before attempting to service or repair the Steering Angle Sensor. Disabling the sir system begins by checking that both front wheels face forward and the
Steering Column lock engages then you can detach the steering components to protect the sir coil assembly. Theehicles should have a Steering Column anti-rotation pin (J 42640) installed to lock the Steering Column. When using the sensor again install a 1.0 to 2.0 mm diameter pin to its center before sensor removal. Sensor replacement becomes necessary when the sensor is removed without this pin. Extract the Steering Column from the vehicle to expose the sensor connection for more efficient working conditions. First remove the
Steering Shaft retainer before drawing the sensor out of the bearing adapter using installed pin retention. When replacing a sensor pull it directly out from the bearing adapter while still attached to the Steering Shaft. After positioning the sensor onto the Steering Shaft and the bearing adapter you should keep the pin installed. During installation position the sensor with a gap of about 3.00 mm from the bearing adapter. Return the sensor connector first then eliminate the pin before placing the sensor retainer onto the Steering Shaft. The installation ends when you return the Steering Column to the vehicle after removing the Steering Column anti-rotation pin (J 42640) and enabling the sir system.
