Malfunction Indicator Lamp: Description and Operation
Description
DESCRIPTION
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. This indicator is located near the lower edge of the instrument
cluster, between the tachometer and the speedometer.
The MIL consists of a stencil-like cutout of the International Control and Display Symbol icon for Engine 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.
The MIL is serviced as a unit with the instrument cluster.
