Chevrolet Sonic Repair Manual: Brake Pedal Position Sensor Calibration

Chevrolet Sonic Repair Manual / Chassis / Brakes / Hydraulic Brakes / Brake Pedal Position Sensor Calibration

Calibration Criteria

Note:

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 performed after the brake pedal position sensor, body control module (BCM), or engine control module (ECM) have been serviced. The calibration procedure will set the brake pedal position sensor home value. This value is used by the BCM and ECM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via serial data.

Calibration Procedure
  1. Apply the parking brake.
  2. Ignition ON, engine OFF, place the transmission in the PARK position for automatic transmission or NEUTRAL position for manual transmission.
  3. Install a scan tool.
  4. Clear all DTCs before proceeding.
  5. Navigate to the Configuration/Reset Functions menu of the BCM.
  6. Select the Brake Pedal Position Sensor Learn procedure and follow the directions displayed on the screen.
  7. Navigate to the Configuration/Reset Functions menu of the ECM.
  8. Select the Learn Functions menu.
  9. Select the Brake Pedal Position Sensor Learn procedure and follow the directions displayed on the screen.
