120 km/h WARNING ALARM

id092200033900


Purpose

•  The 120 km/h warning alarm alerts 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 sounds the 120 km/h warning alarm.
•  The 120 km/h warning alarm sounds in the pattern shown in the figure.

Construction

•  The 120 km/h warning alarm sounds using the buzzer built into 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 alarm is established and the 120 km/h warning alarm sounds (3).
