BASS Data List
BASS High During Learn
- The scan tool displays NO/YES. If a short to battery positive voltage is detected in the stop lamp switch signal circuit during calibration, then the scan tool will display YES.

BASS Learned
- The scan tool displays NO/YES. When the brake pedal position sensor has been calibrated correctly, the scan tool will display YES.

BASS Low During Learn
- The scan tool displays NO/YES. If a short to ground is detected in the stop lamp switch signal circuit during calibration, then the scan tool will display YES.

BASS Moved During Learn
- If the brake pedal is moved during calibration, the scan tool will display YES.

BASS Valid
- The scan tool displays NO/YES. When the brake pedal position sensor has been calibrated correctly, the scan tool will display YES.

Brake Lamp
- The scan tool displays ON/OFF. When the brake is applied the scan tool will display ON.

Current Position
- The scan tool displays COUNTS. The brake pedal position sensor applies a varying voltage to the BCM. The BCM then calculates the current position of the brake pedal.

Learned Home Position
- The scan tool displays COUNTS. The BCM displays the home position of the brake pedal position sensor.

Learn in Progress
- The scan tool displays NO/YES. When the brake pedal position sensor is being calibrated, the scan tool will display YES.
