I/P Dimmer Switch

The IP dimmer switch allows the operator to turn on the courtesy lights from inside the vehicle. When the IP dimmer switch is in the DOME position, the switch sends a voltage signal to the Body Control Module (BCM) through circuit 1495. This action causes the BCM to turn on the courtesy lights. When the IP dimmer switch is off, the BCM turns off the courtesy lights. 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 with the ignition switch in the LOCK or OFF position.
