Brake Pedal Assy: Adjustments

Brake Pedal Position Sensor Calibration

Calibration Criteria

The brake pedal position sensor (BPPS) receives a low reference signal and a 5-volt reference signal from the BCM. Whenever the brake pedal is
applied, the BPPS applies a variable voltage signal to the BCM through the stop lamp switch signal circuit. The BPPS calibration must be performed
after the BPPS or body control module (BCM) have been serviced. The calibration procedure will set BPPS 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 the class 2 communication
bus.

Calibration Procedure

1. Install a scan tool.
2. Select Diagnostics.
3. Turn ON the ignition, with the engine OFF.
4. Select the vehicle.
5. Select Body.
6. Select Radio.
7. Select Body Control Module.
8. Select Module Setup.
9. Select the BPPS calibration procedure and follow the directions displayed on the screen.
