Four Wheel Drive Indicator Lamp: Description and Operation
4WD Indicator - Description
DESCRIPTION
A four-wheel drive indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the optional Non-Trail Rated
four-wheel drive system, this indicator is electronically disabled. This indicator is located within the odometer Vacuum Fluorescent Display (VFD) unit.
The four-wheel drive indicator consists of the text 4WD in the VFD display. The odometer VFD unit is soldered onto the instrument cluster electronic
circuit board, and is visible through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial face of the cluster
overlay. The dark lens over the VFD prevents it from being clearly visible when it is not illuminated. The four-wheel drive indicator text appears in an
amber color and at the same lighting level as the odometer information when it is illuminated by the instrument cluster electronic circuit board.
During daylight hours (exterior lamps are OFF) the odometer VFD unit is illuminated at full brightness for clear visibility. At night (exterior lamps are
ON), the VFD lighting level is adjusted with the other cluster illumination lamps using the panel lamps dimmer function of the interior lighting control
sleeve on the left multi-function switch control stalk. However, a PARADE mode position of the control sleeve allows the VFD unit to be illuminated at
full brightness if the exterior lamps are turned ON during daylight hours.
The four-wheel drive indicator is serviced as a unit with the odometer VFD unit in the instrument cluster.
