Interior Lighting: Overview

WARNING: This page is about a different car, the 2013 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

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
LTM (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
Vanity mirror lamps
Glove compartment lamp
BCM

The demand lamps are used to 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 LEDs
Ambient lighting module (integrated into the overhead console)
Ambient lighting switches (integrated into the overhead console)

The ambient lighting provides aesthetically colored illumination to the center console storage bin and cup holders, the door map pockets, the door pull handles, the door release handles, and the front and rear footwells for illuminated entry or when the ignition is in RUN with the parking lamps on. The ambient lighting is controlled using the buttons and knob on the overhead console.
