Instrument Cluster and Panel Illumination

Instrument Cluster and Panel Illumination

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, 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.

Dimmable Backlighting

NOTE: If the battery is disconnected or discharged, or the instrument panel dimmer switch is disconnected, the instrument panel dimmer switch requires re-calibration. Rotate the instrument panel dimmer switch from the full dim position to the DOME LAMP position. This makes sure that all displays are visible under all lighting conditions.

The dimmable switches and components are illuminated when the parking lamps are on. The level of intensity is adjustable by rotating the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.

The dimmable switches and components consist of:

- HVAC module
- Floor shifter
- Heated driver seat switch (if equipped)
- Heated passenger seat switch (if equipped)
- LH rear heated seat switch (if equipped)
- RH rear heated seat switch (if equipped)
- Message center switch (if equipped)
- Memory set switch (MKX)
- Window control switches (MKX)
- Door lock control switches (MKX)
- Headlamp switch
- Instrument panel dimmer switch
- IC
- Smart Junction Box (SJB)
- Steering wheel switches
- Hazard/passenger air bag disable/traction control switch
- ACM
- Power liftgate release switch
- Roof opening panel switch (if equipped)
- Rear Entertainment Module (RETM) (if equipped)

Non-Dimmable Backlighting

The non-dimmable (fixed) lighting switches and components are illuminated when the delayed accessory relay is energized. The non-dimmable switches and components are illuminated at full lamp intensity.

The non-dimmable lighting switches and components consist of:

- Door lock control switches (Edge)
- Window control switches (Edge)
