Demand Lamps

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

When the BCM is in not in battery saver mode, the interior light output is energized to provide voltage to the demand lamps. The demand lamp relay is integrated into the BCM and is not serviced separately.
