Battery Saver

Note. Time-out is 10 seconds if the vehicle is in factory mode or 0 seconds 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.
any door or liftgate/luggage compartment lid becomes ajar.
an UNLOCK button of the RKE transmitter is pressed.
a valid keypad code is entered while the ignition is OFF.
a door is unlocked using a key.
the door lock switch is pressed.

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) if

the ignition transitions out of OFF.
any door or liftgate/luggage compartment lid becomes ajar.
the UNLOCK button of the RKE transmitter is pressed.
a valid keypad code is entered.
a door is unlocked using a key.
the door lock switch is pressed.

Courtesy Lamps

The BCM controls the courtesy lighting functions and timing by monitoring inputs from the following

Door or liftgate ajar switches
Ignition state
Instrument panel dimmer switch
RKE system

For vehicles equipped with puddle lamps, the DDM and the PDM provide voltage to the left and right puddle lamps based on messaged input from the BCM over the MS-CAN .

The BCM sends a voltage signal to each door or liftgate ajar switch. When the doors or liftgate are closed, the circuit is switched to ground and the voltage is pulled low, indicating closed doors.

For vehicles equipped with door modules, the DDM and the PDM provides 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 light relay. When the interior light relay is energized, voltage is provided to the interior lamps. The BCM controls the ground side of the courtesy lamps for the illuminated entry and exit features.

For keyless entry, the BCM monitors input from the RKE transmitter (directly from the integrated keyhead transmitters (IKTs) on vehicles without push button start) or from the RFA module (on vehicles with push button start) to determine when to activate/deactivate the illuminated entry and exit functions.

The interior courtesy lamps can also be activated from the courtesy lamp switch mounted on the front/driver interior lamp. The front interior lamp (vehicles without a roof opening panel) or the driver interior lamp (vehicles with a roof opening panel) controls the courtesy lamp function of the remaining interior lamp(s). When the courtesy lamp button is pressed on the front/driver interior lamp, the courtesy lamp function for all the lamps is turned on/off. If any door is open, the BCM command overrides the function of the front/driver courtesy lamp switch and activates the courtesy lamps.

The courtesy lamps can be disabled when the doors are opened with the door function switch. When pressed, this switch will disable the interior lamps and will illuminate yellow to indicate the lamps are disabled. Pressing the switch again will re-enable the courtesy lamps and will illuminate blue to indicate that the lamps are enabled.

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 chart 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).

Action	Parking Lamps	Courtesy Lamps	Dimmable Backlighting	Ambient Lighting
RKE transmitter or mechanical unlocking of the doors	On for 25 seconds	On for 25 seconds	On for 25 seconds	Off
RKE transmitter or mechanical locking of the doors	Off	Off	Off	Off 3 seconds after courtesy lamps turned off
Open a closed door after previously unlocking (no ignition state change since unlock)	Off (on for remaining time if unlocked from transmitter or mechanical unlocking of the doors)	On	Off	On
Close all doors	Off	On for 25 seconds	On for 25 seconds	On for 25 seconds
Ignition changed to ON	Off	On for 25 seconds	Off	On
Ignition changed out of ON	Off	On for 25 seconds	On for 25 seconds	On for 25 seconds
Open a door after the ignition is changed to OFF	Off	On	Off	On (color is red on the open door)
Ignition is OFF and doors are unlocked from the door lock switch	Off	On for 25 seconds	Off	Off
Ignition is OFF and doors are locked from the door lock switch	Off	Off	Off	Off

Demand Lamps

When the BCM is in not in battery saver mode, the interior light relay is energized to provide voltage to the demand lamps.

Ambient Lighting

The ambient lighting subsystem consists of the ambient lighting switch, dimmer control and the ambient lighting module (all integrated into the overhead console), and the Light Emitting Diodes (LEDs) located within the floor console, front door panels and under the instrument panel footwell areas. The ambient lighting is operational when the ignition is in any state other than OFF (the exception is when it is used in conjunction with the illuminated entry/exit features), the headlamps are on and the outside ambient light level is low. The ambient lighting switch cycles the Light Emitting Diodes (LEDs) through 7 different color combinations. The brightness is changed using the dimmer control which allows the Light Emitting Diodes (LEDs) to be turned off as well.

The right search mode control switch activates all ambient light areas and all dome lamps. The search mode control switch needs to be pressed again to deactivate the dome lamps and return to the previously selected ambient light color.

The ambient lighting Light Emitting Diodes (LEDs) provide illumination to the

Cup holders (located in the center console)
Front footwells (located under the instrument panel)
Rear footwells (located in the rear of the center console)
Front inside pull handles (located in each door trim panel)
Front door map pockets (located in each door trim panel)

The ambient lighting control module controls the color and light intensity. The ambient lighting module receives information from the BCM through a LIN circuit for illuminated entry/exit functions. The ambient lighting module provides voltage to all of the Light Emitting Diodes (LEDs). A secondary LIN circuit is routed from the ambient lighting module to all of the Light Emitting Diodes (LEDs). Each LED changes color and intensity based on the input from the ambient lighting module.

As an additional function, the ambient lighting illuminates red on any open door.

Door Ajar Switch

The door ajar switches (ground switches) each receive a voltage signal from the BCM on independent circuits. When the door is closed, the door ajar switch is closed, routing the signal to ground. When the door is opened, the door ajar switch opens.

For vehicles equipped with one-touch up/down window function, ground is provided to the door ajar switches from the door modules.

Interior Lamp

All of the interior lamps receive voltage from the interior lamp relay (integrated into the BCM ) when the battery saver feature is not active. This is used by each interior lamp to power the LED within it.

The front/driver interior lamp receives voltage from the BCM when the courtesy lamps are activated and no voltage when deactivated. The front interior lamp uses a private communication protocol to command the rear lamps on or off.
