Trunk Lamp: Description and Operation



I/P COMPARTMENT LAMP

The inadvertent power supply voltage circuit of the body control module (BCM) provides battery positive voltage to the instrument panel (I/P) compartment lamp. When the I/P compartment is opened, a switch closes to provide a ground circuit and the I/P compartment lamp illuminates. In the event that any of these lamps were to remain illuminated for a period of more than 10 minutes with the ignition switch in the OFF position, the BCM will deactivate the inadvertent power supply voltage circuit to prevent a total battery discharge condition. Ground is provided to the I/P compartment lamp at G203.
