TURN AND HAZARD INDICATOR ALARM

id092200020800


Purpose

•  The turn and hazard indicator alarm notifies the driver that a turn light or the hazard warning lights are flashing.

Function

•  When the instrument cluster receives the turn signal/hazard warning indicator light illumination request signal sent from the front body control module (FBCM) via the CAN signal, the turn and hazard indicator alarm sounds simultaneously with illumination on/off of the direction/hazard warning indicator lights.
•  The turn and hazard indicator alarm sound pattern is as follows:

Sound frequency (Hz)
Alarm when turn signal/hazard warning indicator lights illumination off → on: 1,400
Alarm when turn signal/hazard warning indicator lights illumination on → off: 1,300
Sound frequency
Continuously
Wave pattern


Construction

•  The turn and hazard indicator alarm sounds using the buzzer built into the instrument cluster.

Construction, Operation

1.  The instrument cluster receives (1) the turn signal/hazard warning indicator light request signal from the front body control module (FBCM).

2.  The instrument cluster microcomputer turns the transistor on (2) based on the turn signal/hazard warning indicator light request signal.

3.  When the transistor turns on, a ground circuit with the alarm is established and the alarm sounds (3).
