BLIND SPOT MONITORING (BSM) WARNING BUZZER
2016 – MX-5 – i-ACTIVSENSE
BLIND SPOT MONITORING (BSM) WARNING BUZZER
Purpose
-
The blind spot monitoring (BSM) warning buzzer alerts the driver of a possible collision with an approaching vehicle when changing lanes or backing up.
Functions
-
When the instrument cluster receives a blind spot monitoring (BSM) warning request signal from the blind spot monitoring (BSM) control module (LH), the blind spot monitoring (BSM) warning buzzer in the instrument cluster is activated.
-
The blind spot monitoring (BSM) warning buzzer sound pattern is a shown in the figure.
Construction
-
The blind spot monitoring (BSM) warning buzzer is integrated with the instrument cluster, and it produces a buzzer sound.
Operation
-
The instrument cluster receives (1) the blind spot monitoring (BSM) warning request signal from the blind spot monitoring (BSM) control module (LH).
-
The instrument cluster turns the transistor on (2) based on the blind spot monitoring (BSM) warning request signal.
-
When the transistor turns on, a ground circuit with the blind spot monitoring (BSM) warning sound is established, and the blind spot monitoring (BSM) warning sound is activated (3).
Fail-safe
