The Blind Spot Monitoring (BSM) warning alarm warns the driver of a possible accident.
The BSM warning alarm sounds using the buzzer built into the instrument cluster.
The instrument cluster receives (1) the warning sound request signal from the BSM control module (LH).
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).
Function not equipped.
