Chevrolet Sonic Repair Manual: 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.
