EXCESSIVE SPEED WARNING SOUND


id151400001800


Purpose

•  The excessive speed warning sound alerts the driver that the vehicle speed exceeds the speed of the speed limit sign.

Functions

•  If the instrument cluster receives an excessive speed warning request signal from the forward sensing camera (FSC), it activates the excessive speed warning sound using the buzzer in the instrument cluster.
•  The excessive speed warning sound is activated in the pattern shown in the figure.

Construction

•  The excessive speed warning sound is activated using the buzzer built into the instrument cluster.

Operation

1.  The instrument cluster turns on (1) the transistor if the vehicle speed, according to the speed limit set in the personalization features, exceeds the speed limit of the speed limit sign display signal received from the FSC by 1 km/h {0.6 mph}.
2.  When the transistor turns on, a ground circuit for the buzzer is established and the excessive speed warning sound is activated (2).
