Glove Box Lamp: Description and Operation

I/P COMPARTMENT LAMP

The inadvertent power supply voltage circuit of the BCM provides battery positive voltage to the instrument panel compartment lamp. When the IP compartment is opened, a switch closes to provide a ground circuit and the IP 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 IP compartment lamp at G203.
