Steering Angle Sensor Module (SASM): Installation

For vehicles with Active Park Assist 

  1. 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:
    1. Orient the front wheels in the straight-ahead position.
    2. Connect the SASM electrical connector.
    3. Carefully rotate the sensor clockwise until it stops.
    4. Rotate the sensor counterclockwise two and one-half turns.
    5. Using the scan tool, read the SASM position PID (SWA POS). The PID should read approximately 0 degrees. If not, repeat the procedure.
    6. Disconnect the SASM electrical connector.

    For vehicles without Active Park Assist
