Scan Tool Data Definitions: Data
- Backlight Dimming
-
The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled I/P backlighting based on the position of the I/P dimmer switch, thumbwheel.
- Battery Voltage
-
The scan tool displays the battery system voltage received by the module.
- Dimming Input
-
The scan tool displays the voltage value indicating the position of the I/P dimmer switch, thumbwheel. The scan tool displays 4 volts when the I/P dimmer switch is in the FULL DIM position. The scan tool displays 0 volts when the I/P dimmer switch is in the FULL BRIGHT position.
- Dimming Potentiometer
-
The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled door switch backlighting based on the position of the I/P dimmer switch, thumbwheel.
- Indicator Dimming
-
The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled I/P backlighting based on the position of the I/P dimmer switch, thumbwheel.
- Light Sensor
-
The scan tool displays the output voltage of the ambient light sensor based on the intensity of light detected. As the light intensity increases, the sensor displayed voltage decreases. In the LIGHT state, a low voltage, not less than 1.75 volts, is present and the DRL will be ON. In the DARK state, a high voltage, up to 4.9 volts, is present and the headlamps will be ON.
- Memory Switch Backlight
-
The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled memory switch backlight based on the position of the I/P dimmer switch, thumbwheel.
- Window Switch Backlight
-
The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled window switch backlight based on the position of the I/P dimmer switch, thumbwheel.
