Brake Pedal Position Sensor Calibration



Brake Pedal Position Sensor Calibration

Calibration Criteria

Important: Do not apply the brake pedal during the brake pedal position sensor calibration procedure. Any movement of the brake pedal during this procedure will cause the calibration procedure to fail. If this occurs, the brake pedal position sensor calibration must be repeated.

Brake pedal position sensor calibration must be preformed after the brake pedal position sensor or electronic brake control module (EBCM) have been serviced. The calibration procedure will set the brake pedal position sensor home value. This value is used by the EBCM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via the class 2 communication bus.

Calibration Procedure

1. Apply the parking brake.
2. Place the transmission in the PARK position for automatic transmission or NEUTRAL for manual transmission.
3. Install a scan tool.
4. Turn ON the ignition, with the engine OFF.
5. Select Chassis.
6. Select DRP/ABS/TCS/VSES.
7. Select Special Functions.
8. Select the BPP Sensor Calibration and follow the directions displayed on the screen.
