Low Tire Pressure Indicator: Description and Operation
Low Tire Pressure Indicator - Description
DESCRIPTION
A Tire Pressure Monitor (TPM) indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the TPM system, this
indicator is electronically disabled. This indicator is located within the odometer Vacuum Fluorescent Display (VFD) unit.
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 VFD unit.
The odometer VFD unit is soldered onto the instrument 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 VFD prevents it from being clearly visible when it is
not illuminated. The indicator appears in an amber color (domestic market vehicles) or in the same blue-green color as the odometer information (export
market vehicles) when it is illuminated by the cluster electronic circuit board. Once illuminated, the TPM indicator as well as all of the odometer VFD
information is illuminated at full (daytime) brightness and cannot be dimmed until the TPM indicator is extinguished.
The TPM indicator is serviced as a unit with the odometer VFD unit in the instrument cluster.
