TURN AND HAZARD INDICATOR ALARM

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 turn signal/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 turn signal/hazard warning indicator lights.

• The turn and hazard indicator alarm is activated in the pattern shown in the figure.

Sound frequency (Hz)	Turn signal/hazard warning indicator lights turn off to on: 1,400 Turn signal/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 turn signal/hazard warning indicator signal via CAN communication from the BCM.

2. The instrument cluster turns the transistor on (2) based on the turn signal/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).

Fail-safe

• Not applicable
