Battery positive voltage is applied at all times to the MONITORED LD relay 37 coil and switch side. The BCM applies a ground to the MONITORED LD relay 37 coil side, energizes the relay and closes the switch contacts, The BCM then allows battery positive voltage to the MONITORED LD fuse 2 and then the IP compartment lamp. When the IP compartment is opened, its switch closes providing a ground circuit, and the IP compartment lamp illuminates.
