IP Dimmer Switch
The IP dimmer switch allows the operator to turn ON the courtesy lights from the inside of the vehicle. When the IP dimmer switch is in the DOME position the switch sends a ground signal to the BCM through circuit 156. This will cause the BCM to turn on the courtesy lights. When the IP dimmer switch is OFF, the BCM turns the courtesy lights OFF. The IP dimmer switch is protected by the inadvertent load (battery rundown) protection in case the ignition switch is left in the DOME position with the ignition switch OFF.The IP dimmer switch is also used in order to change the interior lighting modes during the feature customization. Refer to Body Control System Circuit Description in Body Control System. The IP dimmer switch is also used in order to enter the Input/Output test during the BCM diagnostics.
