Oil Change Reminder Lamp: Description and Operation
Description
DESCRIPTION
A change oil indicator is standard equipment on all instrument clusters. However, on vehicles manufactured for export markets or vehicles equipped with
the optional diesel engine, this indicator is electronically disabled. The change oil indication appears within the odometer Vacuum Fluorescent Display
(VFD) unit. The change oil indicator consists of cycling textual CHAngE and OIL messages which appear 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 on the lower
edge of the speedometer 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 change oil textual messages appear in the same blue-green color and at the same lighting level as the odometer information when they
are illuminated by the instrument cluster electronic circuit board.
The change oil indicator is serviced as a unit with the VFD in the instrument cluster.
