Inadvertent Power Feature

Inadvertent power feature provides a similar function for the interior lamps as a retained accessory power feature. The BCM will energize the courtesy lamp high control circuit and the inadvertent power courtesy lamp circuits when the BCM is in the active state (awake). When these circuits are energized, voltage is to all the interior lights, including the courtesy, cargo, reading and vanity lamps. Any time a switch is activated to the ON position the BCM will wake up and apply voltage to the lamps after the ignition is turned OFF so that the interior lamps may be operated. The inadvertent power feature will also act as battery run down protection by deactivating the circuits after 20 minutes once the BCM becomes inactive (ignition OFF and no BCM input activity.)
