Malfunction Lamp / Indicator: Description and Operation
Description
DESCRIPTION
An airbag (also known as Supplemental Restraint System/SRS) indicator is standard equipment on all instrument clusters. This indicator is located below
and to the right of the speedometer needle hub. On vehicles equipped with the optional steering wheel buttons, illumination of this indicator may also be
accompanied by the display of certain textual messages in the cluster multi-function display.
The airbag indicator consists of a stencil-like cutout of the text SRS 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. A red Light Emitting Diode (LED) behind the cutout in the opaque
layer of the overlay causes the indicator to appear in red 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 airbag indicator is serviced as a unit with the instrument cluster.
