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.
