Instrument Cluster and Panel Illumination

INSTRUMENT CLUSTER AND PANEL ILLUMINATION

The instrument cluster and panel illumination is used to provide backlighting to the instrument panel, switches and control components when the headlamp switch is in either the parking lamps ON or headlamps ON position. The level of intensity is adjustable by pushing the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.

Principles of Operation
The instrument cluster and panel lighting system is powered through the smart junction box (SJB). The instrument cluster illumination is controlled by the output of the instrument panel dimmer switch. The dimmable backlighting components are:
- hazard switch
- rear defroster switch
- message center switches
- parking aid switch
- transaxle range select
- fog lamp switch

The non-dimmable backlighting components are:
- driver-side front door lock and power window control switch
- passenger-side front door lock and power window control switch
- driver-side rear door power window control switch
- passenger-side rear door power window control switch
