Service Procedure

  1. Remove the brake apply sensor (BAS).
    3.1. Disconnect the electrical wiring harness from the switch. While holding the connector, on the harness, press the connector down. Pull on the harness to remove it from the vehicle.​





    Note: Do NOT loosen the screw to remove the BAS. Tighten the screw to a torque greater than 8 N·m(71 lb in). The screw head will break off. Discard the screw head.

    3.2. Remove the BAS screw.
    3.3. Slide the BAS to the left to remove it from anti rotation pin.
    3.4. Discard the BAS.​


    Note: The new BAS, P/N 22769186, is white.




    Install a new BAS.
    4.1. Slide the BAS from the left to right position on the brake pedal assembly.​






    4.2. Make sure that the fork (1) is aligned with the pin on the brake assembly.
    4.3. Line up the screw (2) to the BAS hole and then fasten. Tighten the screw to 3 N·m(27 lb in).​
    Perform a Brake Pedal Position Sensor Calibration.
    Note: Do not apply the brake pedal during the brake pedal position (BPP) sensor calibration procedure. Any movement of the brake pedal during this procedure will cause the calibration procedure to fail. If this occurs, the sensor calibration must be repeated. Brake pedal position (BPP) sensor calibration must be performed after the BAS switch or body control module (BCM) have been serviced. The calibration procedure will set the sensor home value. This value is used by the BCM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via serial data.

    5.1. Apply and slowly release the brake pedal two times.
    5.2. Apply the parking brake.
    5.3. Place the transmission gear selector in the "P" PARK position.
    5.4. Connect MDI and GDS.
    5.5. Clear all BCM diagnostic trouble codes (DTCs).
    5.6. Navigate to the Vehicle Control Systems menu.
    5.7. Select Module Setup menu item.
    5.8. Select BCM menu item.​

    5.9. Select the BPP Sensor Calibration procedure and follow the directions displayed on the screen
  2. Perform ECM BAS Home Learn Procedure.
    6.1. Put the ignition key in the RUN position (no crank).​




    6.2. Apply and slowly release the brake pedal two times and then wait 2 seconds.​

    6.3. Repeat Step 6.2 eight times.​
