Fuel Filler Cap Warning Indicator: Description and Operation
Description
DESCRIPTION
A gas cap indicator is standard equipment on all instrument clusters. However, on vehicles equipped with the optional diesel engine, this indicator is
electronically disabled. The gas cap indication appears within the odometer Vacuum Fluorescent Display (VFD) unit. The gas cap indicator consists of a
textual gASCAP message which appears in place of the odometer information in the odometer display.
The odometer VFD is soldered onto the cluster electronic circuit board, and is visible through a window with a smoked clear lens located at the base of
the cluster overlay right gauge dial face (Dodge) or the tachometer dial face (Chrysler). The dark lens over the VFD prevents it from being clearly visible
when it is not illuminated. The gas cap textual message appears in the same blue-green 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 thumbwheel of the headlamp switch on
the instrument panel. However, a PARADE mode position of the thumbwheel allows the VFD unit to be illuminated at full brightness if the exterior
lamps are turned ON during daylight hours.
The gas cap indicator is serviced as a unit with the odometer VFD in the instrument cluster.
