Feature Customization - IP Dimmer Switch

The IP dimmer switch allows the operator to activate the interior courtesy lights from inside the vehicle. When the IP dimmer switch is in the DOME position, the switch sends a ground signal to the BCM through CKT 156. This action causes the BCM to activate the interior courtesy lights. When the IP dimmer switch is in the OFF position, the BCM deactivates the interior courtesy lights. With the ignition switch in the LOCK or OFF position, the IP dimmer switch is protected by the inadvertent load (battery rundown) protection in case the IP dimmer switch is left in the DOME position.

The IP dimmer switch is also used to change the interior lighting modes during the feature customization. Refer to Feature Customization for more information. In addition, the IP dimmer switch is also utilized to enter the input/output test during BCM diagnostics.
