Instrument Cluster and Panel Illumination: Notes

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The Instrument Cluster (IC) and panel illumination is used to provide backlighting to the dimmable and non-dimmable switches and control components.

For Edge, if the exterior lamps are activated during daytime sunload conditions by the autolamp system, the message center illumination remains at full intensity and does not dim from the instrument panel dimmer switch during this condition. If the vehicle travels under a bridge or a tunnel, the low level of ambient light causes the illumination level of the message center to change to the level set by the instrument panel dimmer switch. The message center illumination changes back to full intensity when the intense ambient light is restored.

For MKX, if the exterior lamps are activated during daytime sunload conditions by the autolamp system, the message center, the Audio Control Module (ACM), the HVAC module and switch illumination remain at full intensity and do not dim from the instrument panel dimmer switch during this condition. If the vehicle travels under a bridge or a tunnel, the low level of ambient light causes the illumination level of the message center, the ACM , the HVAC module and switches to change to the level set by the instrument panel dimmer switch. The message center, the ACM , the HVAC module and switch illumination change back to full intensity when the intense ambient light is restored.
