Oil Change Reminder Lamp: Description and Operation
Description
DESCRIPTION
A change oil indicator is standard equipment on all instrument clusters. The change oil indication appears within the reconfigurable dot matrix Organic
Light Emitting Diode (OLED) display unit. The change oil indicator consists of a textual OIL CHANGE REQUIRED message which appears in place
of the compass/trip computer information in the reconfigurable dot matrix display.
The dot matrix OLED 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 tachometer gauge dial face of the cluster overlay. The dark lens over the OLED prevents it from being clearly visible when it is not
illuminated. The change oil textual message appears in the same white color and at the same lighting level as the compass/trip computer information
when it is illuminated by the instrument cluster electronic circuit board.
The change oil indicator is serviced as a unit with the OLED in the instrument cluster.
