Low Tire Pressure Indicator: Description and Operation
Description
DESCRIPTION
A Tire Pressure Monitor (TPM) indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the optional TPM,
this indicator is electronically disabled. This indicator is located above the engine coolant temperature gauge on the cluster overlay, to the right of the
tachometer.
The TPM indicator consists of a stencil-like cutout of an icon that represents a cross-section of a tire with a centered exclamation point 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 TPM indicator is serviced as a unit with the instrument cluster.
