Park Brake Switch.: The scan tool display ON/OFF. When the park brake is applied, the scan tool will display ON.

Park Lamp Switch.: The scan tool displays ON/OFF. When the headlamp switch is in the PARK position, the scan tool will display ON.

RF Door Lock Switch.: The scan tool displays ON/OFF. When the RF door is open, the scan tool will display ON.

RR Door Open Switch.: The scan tool displays ON/OFF. When the RR door is open, the scan tool will display ON.

Right Turn Signal.: The scan tool displays ON/OFF. When the turn signal switch is placed in the right turn position, the scan tool will display ON.

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.: The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the low beam headlamps are turned ON.

Park Lamp Relay.: The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the park lamps are turned ON.

RF Turn/DRL lamp Status.: The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the right turn signal is turned ON or when the BCM turns ON the DRL lamps.

RR Stop/Turn Signal Lamp.: The scan tool displays ON/OFF. This output of the BCM is displayed as ON when the right turn signal is turned ON or when the brakes are applied.

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.
