Battery Saver

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Time-out is 1 minute if the vehicle has less than 80 km (50 miles).

To save battery voltage, the BCM provides automatic shut-off of the courtesy and demand lamps after a time-out period when the ignition is OFF. A timer in the BCM starts when any of the following occur:

the ignition changes to OFF
any door becomes ajar while the ignition is OFF
an UNLOCK button of the Remote Keyless Entry (RKE) transmitter is pressed while the ignition is OFF
a valid keypad code is entered while the ignition is OFF
the instrument panel dimmer switch is used to turn the courtesy lamps on while the ignition is OFF

When 10 minutes have elapsed, the BCM automatically shuts off voltage to the lamps. The timer restarts (voltage is restored if the BCM is in battery saver mode) if any of the following occurs:

the ignition changes out of OFF
any door becomes ajar
the UNLOCK button of the RKE transmitter is pressed
a valid keypad code is entered
the instrument panel dimmer switch is pressed
