Battery Saver

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Time-out is 10 seconds if the vehicle is in factory mode or 1 minute if the vehicle is in transport mode.

The BCM provides automatic shut-off of the courtesy and demand lamps after a time-out period when the ignition is OFF. When 10 minutes (30 minutes for demand lamps) have elapsed, the BCM automatically shuts off voltage to the lamps. A timer in the BCM starts/restarts (voltage is restored if the BCM is in battery save mode) when:

the ignition transitions to OFF.
the front or rear interior lamp was switched ON.
any door becomes ajar.
any button of a RKE transmitter is pressed.
a door is unlocked using the passive entry feature.
a valid code was entered on the keyless entry keypad.
