Dimmer Switch: Description and Operation
DIMMER SWITCH
The dimmer switch allows the operator to activate the interior courtesy lights from inside the vehicle. When the dimmer switch is in the DOME position,
the switch sends a ground signal to the BCM through the interior lights ON request input circuit. This action causes the BCM to activate the interior
courtesy lights.
When the 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 dimmer switch is protected by the inadvertent load protection in case the dimmer switch is left in the DOME position.
The dimmer switch is also used to change the interior lighting modes during the feature customization. Refer toVehicle Personalization in
Personalization for more information. In addition, the dimmer switch is also utilized to enter the input/output test during BCM diagnostics.
