Battery Saver
WARNING: This page is about a different car, the 2015 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The battery saver time-out is 1 minute if the vehicle has less than 201 km (125 mi).
NOTE:
The battery saver does not control the parking lamps if the headlamp switch is in the PARKING LAMPS ON position.
To save battery voltage, the BCM provides automatic shut-off of the interior and exterior lamps after a time-out period when the ignition is off. The BCM monitors the ignition state and input from the RKE system to determine when to energize or de-energize the battery saver relay and to shut the power off to the lamps.
A timer in the BCM starts when:
- the ignition changes to OFF.
- any door or liftgate becomes ajar while the ignition is off.
- an UNLOCK button of the RKE transmitter is pressed while the ignition is off.
- a valid keypad code is entered while the ignition is off.
- the courtesy lamp switch (integrated into the main light 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:
- the ignition transitions out of OFF.
- any door or liftgate becomes ajar.
- the UNLOCK button of the RKE transmitter is pressed.
- a valid keypad code is entered.
- the courtesy lamp switch is pressed.
