Steering Angle Sensor Module (SASM): Installation
- If the arrow on the SASM ring and the arrow on the sensor housing are misaligned and/or the straight-ahead position of the sensor is not known, follow these steps to align the sensor prior to installing the sensor:
- Orient the front wheels in the straight-ahead position.
- Connect the SASM electrical connector.
- Carefully rotate the sensor clockwise until it stops.
- Rotate the sensor counterclockwise two and one-half turns.
- Using the scan tool, read the SASM position PID (STEER_ANGL). The PID should read approximately 0 degrees. If not, repeat the procedure.
- Disconnect the SASM electrical connector.
- Make sure the sensor ring arrow is lined up with the SASM housing arrow as shown in illustration and position the sensor into the multifunction switch housing.
- Connect the SASM electrical connector.
- Install the SASM to the clockspring. Make sure that the tabs on the inner ring of the SASM align with the notches on the clockspring and that the locking tabs on the clockspring hold the SASM to the clockspring securely.
- Install the clockspring. For additional information, refer to
SUPPLEMENTAL RESTRAINT SYSTEM
.
- If the SASM was aligned using the scan tool, DTCs may be present in the Restraints Control Module (RCM). Using the scan tool, clear the DTCs in the RCM.
- Calibrate the ABS module.
- Carry out the IVD Initialization sequence for the steering angle sensor. Follow the scan tool directions.
NOTE:
Slight rotation of the SASM ring is allowed to align the 2 arrows.
