Battery Saver
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. A timer in the BCM starts when:
the ignition transitions to OFF. the front or rear interior lamp was switched ON. any door or the luggage compartment lid 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.
When 10 minutes (30 minutes for demand lamps) 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) when:
the ignition transitions out of OFF. the front or rear interior lamp was switched ON. any door or the luggage compartment lid 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.
Courtesy Lamps
The BCM controls the courtesy lighting functions and timing by monitoring inputs from the following:
Ignition state Door ajar switches RKE system
The BCM sends a voltage signal to each door ajar switch. When the doors are closed, the circuit is switched to ground and the voltage is pulled low, indicating closed doors.
For vehicles with a memory seat, the DDM and the PDM provide ground for the door ajar switch.
The BCM monitors the ignition state and inputs from the RKE system to determine when to energize the interior lighting output. When the interior lighting output is energized, voltage is provided to the interior overhead lamps.
Illuminated Entry and Exit
The illuminated entry and exit features provide temporary illumination of the parking lamps, the dimmable backlighting, the ambient backlighting and the courtesy lamps. Refer to the table for additional information.
NOTE: An arbitrator (software programming) within the BCM determines which actions take precedence over others (for example, an open door keeps the courtesy lamps on even when a command to lock the doors is received).
