Purpose
The Blind Spot Monitoring (BSM) warning alarm warns the driver of a possible accident.
Function
If the instrument cluster receives a warning sound request signal from the BSM control module (RH), it sounds the BSM warning alarm using the buzzer in the instrument cluster.
The BSM warning alarm sound pattern is as shown in the figure.
Construction
The BSM warning alarm sounds using the buzzer built into the instrument cluster.
Operation
The instrument cluster receives (1) the warning sound request signal from the BSM control module (RH).
The instrument cluster turns the transistor on (2) based on the warning sound request signal.
When the transistor turns on, a ground circuit with the alarm is established and the alarm sounds (3).
Fail-safe
Function not equipped.
