Inadvertent Power Timer

Range: 0-1216 seconds
The BCM uses this feature in order to protect the battery against inadvertent battery rundown caused by devices that attach to the courtesy lamp circuit. If the following lights remain ON, the BCM will turn the lights OFF after 20 minutes:
^ The dome/courtesy lamp
^ The vanity lamp
^ The overhead reading lamp
^ The underhood or the glove box lamp

The lights are turned OFF by the inadvertent power relay. The inadvertent power relay supplies power to the courtesy lamp circuit when the ignition is in the OFF position. The number of seconds displayed refers to the amount of time left before the BCM will turn the relay OFF.
