BCM Outputs
Backup Lamps
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the backup lamps are turned ON.
Brake Applied Outputs
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the brake pedal is applied.
Front Fog Lamp Relay
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the fog lamps are turned ON.
Instrumentation Backlight
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the I/P lamps are commanded ON by the BCM.
Interior Lamp Output
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the interior lamps are turned ON.
LF Turn/DRL Lamp Status
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the left turn signal is turned ON or when the BCM turns ON the DRL lamps.
LR Stop/Turn Signal Lamp
- The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the left turn signal is turned ON or when the brakes are applied.
Low Beam Relay Command

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.
