Traction Control Indicator Lamp: Description and Operation
ESP With BAS Indicator - Description
DESCRIPTION
An ESP/BAS indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the optional Electronic Stability
Program (ESP)/Brake Assist System (BAS), this indicator is electronically disabled. This indicator is located near the bottom of the cluster overlay,
between the speedometer and the tachometer. Illumination of this indicator may also be accompanied by the display of certain textual messages in the
cluster reconfigurable dot matrix display.
The ESP/BAS indicator consists of a stencil-like cutout of the text ESP BAS 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 ESP/BAS indicator is serviced as a unit with the instrument cluster.
