Interior Lighting - Overview: Overview

The interior lighting system consists of:

• Courtesy lamps
• Demand lamps
• Ambient lighting (if equipped)

The courtesy lamps subsystem consists of:

• Interior lamps
• Puddle lamps (if equipped)
• Door ajar switches (integrated into the door latches)
• Liftgate ajar switch (manual liftgate)
• Courtesy lamp switch (integrated into the front/driver interior lamp)
• SCCM
• DDM
• PDM
• BCM
• RGTM (power liftgate)

The courtesy lamps provide illumination to the interior of the vehicle (and below the exterior mirrors if equipped with puddle lamps) when entering or exiting the vehicle or when requested using the courtesy lamp switch located on the interior lamp.

The demand lamps subsystem consists of:

• Interior lamps (map lamps)
• Vanity mirror lamps
• Glove compartment lamp
• BCM

The demand lamps provide illumination to specific areas within the vehicle when needed.

The BCM energizes the interior light relay to supply voltage to the demand lamps when the battery saver feature is not active.

The ambient lighting subsystem consists of:

• Ambient lighting Light Emitting Diodes (LEDs)
• FDIM (touchscreen)
• BCM

The ambient lighting is controlled using the FDIM (touchscreen) controls. The ambient lighting provides aesthetically colored illumination to the following locations for illuminated entry or when the ignition is in RUN with the parking lamps on:

• Floor console cup holders
• Floor console bin
• Front interior door release handles
• Front door map pockets
• Front footwells
• Rear footwells (rear of floor console)
