Brake Pedal Position Sensor Calibration
Calibration Criteria
The brake pedal position (BPP) sensor receives a low reference signal and a 5 volt reference signal from the electro hydraulic power steering (EHPS) module. Whenever the brake pedal is pressed, the brake pedal position sensor applies a variable voltage signal to the EHPS module through the BPP sensor signal circuit. Brake pedal position sensor calibration must be performed after the brake pedal position sensor or EHPS system have been serviced. The calibration procedure will set brake pedal position sensor home value. This value is used by the EHPS module to determine the brake pedal position and the brake pedal rate. These two outputs are provided to the hybrid control module (HCM) via GMLAN.
Calibration Procedure
1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Important:
Make sure the brake pedal is not pressed before sending the BPP sensor calibration command.
Navigate to the Special Functions screen on the scan tool and select BPP Sensor Calibration in order to perform the brake pedal position sensor calibration.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
