Ambient Lighting
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The ambient lighting subsystem consists of the BCM, and the Light Emitting Diodes (LEDs) located within the floor console, front and rear door panels, instrument panel and front and rear 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 BCM provides the voltage to the ambient lighting system, while the touchscreen (FDIM) is used to turn the ambient lighting feature on or off. A LIN circuit is routed from the BCM to all of the Light Emitting Diodes (LEDs).
