Instrument Cluster and Panel Illumination

Instrument Cluster and Panel Illumination

Overview

The backlighting system consist of dimmable components and non-dimmable components.

Dimmable Components

The functional dimmable components are:

- Driver heated seat switch

- Floor shifter

- Instrument panel dimmer switch

- Front Controls Interface Module (FCIM)

- Headlamp switch

- HVAC module

- Passenger heated seat/ambient lighting switch

- Start/stop switch

- Steering wheel switches

- Instrument Panel Cluster (IPC) (via network message)

- Front Control/Display Interface Module (FCDIM) (via network message)

- Body Control Module (BCM)

The dimmable backlighting is controlled by the BCM (Body Control Module). The dimmable switches and components are illuminated when the parking lamps are on. The instrument panel dimmer switch is a single detent rocker switch used to control all dimmable interior illuminated components. The up detent increases dimmable backlighting intensity and the down detent decreases dimmable backlighting intensity. When the parking lamps are off, the Instrument Panel Cluster (IPC) is illuminated to full brightness.

Non-Dimmable Components

The functional non-dimmable components are:

- Window control switches

The non-dimmable illumination provides backlighting to the window switches when the ignition relay is energized.
