Ambient Light Sensor: The scan tool displays 0-255 counts. The counts vary based upon the ambient light level at the sensor. When the ambient light level is high the counts will increase. When the ambient light level is low the counts will decrease. The IPC uses this information for interior light dimming operation.
Switch Dimming: The scan tool displays 0-255 counts. The switch dimming counts vary based upon the dimming switch position and ambient light level information. When the dimming switch is rotated to bright, the switch dimming counts will increase. When the dimming switch is rotated to dim, the switch dimming counts will decrease. The headlamps or parklamps must be on to read this data.
