120 km/h WARNING LIGHT

id092200034000


Purpose

•  The 120 km/h warning light notifies the driver that the current vehicle speed exceeds 120 km/h {74.6 mph}.

Function

•  When the instrument cluster receives a 120 km/h {74.6 mph} vehicle speed signal sent from the PCM via the CAN signal, it illuminates the 120 km/h warning light.

Construction

•  The instrument cluster microcomputer controls the illumination on/off of the 120 km/h warning light based on the 120 km/h {74.6 mph} vehicle speed signal from the PCM.
•  The 120 km/h warning light is set in the instrument cluster.

Operation

1.  The instrument cluster receives (1) the vehicle speed signal from the PCM.

2.  The instrument cluster microcomputer turns the transistor on (2) based on the 120 km/h {74.6 mph} vehicle speed signal.

3.  When the transistor turns on, a ground circuit with the 120 km/h warning light is established and the 120 km/h warning light illuminates (3).
