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.

Functions

•  When the instrument cluster receives a direction indicator/hazard warning indicator signal sent from the BCM via the CAN communication, it activates the turn and hazard indicator alarm simultaneously with the turning on/off of the direction indicator/hazard warning indicator lights.
•  The turn and hazard indicator alarm is activated in the pattern shown in the figure.

Sound frequency (Hz)
Direction indicator/hazard warning indicator lights turn off to on: 1,400
Direction indicator/hazard warning indicator lights turn on to off: 1,300
Wave pattern


Construction

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

Operation

1.  The instrument cluster receives (1) a direction indicator/hazard warning indicator signal via CAN communication from the BCM.

2.  The instrument cluster turns the transistor on (2) based on the direction indicator/hazard warning indicator signal.

3.  When the transistor turns on, a ground circuit with the turn and hazard indicator alarm is established and the turn and hazard indicator alarm is activated (3).
