4WD Low Indicator - Description
4WD LOW INDICATOR
A 4WD low indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the optional four-wheel drive system and
electronically shifted transfer case, this indicator is electronically disabled. This indicator is located near the bottom of the cluster overlay, between the
speedometer and the tachometer. Illumination of this indicator may also be accompanied by the display of certain textual messages in the cluster
reconfigurable dot matrix display.
The 4WD low indicator consists of a stencil-like cutout of the text 4WD LOW in the opaque layer of the instrument cluster overlay. The dark outer layer
of the overlay prevents the indicator from being clearly visible when it is not illuminated. An amber Light Emitting Diode (LED) behind the cutout in the
opaque layer of the overlay causes the indicator to appear in amber through the translucent outer layer of the overlay when it is illuminated from behind
by the LED, which is soldered onto the instrument cluster electronic circuit board.
When the exterior lighting is turned ON, the illumination intensity of the 4WD low indicator is dimmable, which is adjusted along with the cluster
general illumination lighting using the panel lamps dimmer control sleeve on the left multi-function switch control stalk.
The 4WD low indicator is serviced as a unit with the instrument cluster.
