TURN SIGNAL/HAZARD WARNING INDICATOR LIGHTS

id091800013500

Purpose

• Notifies the user that a turn lights are flashing.

Function

• When the instrument cluster receives a turn signal or hazard warning indicator signal sent from the front body control module (FBCM) via CAN communication, it flashes the turn signal/hazard warning indicator lights.

Note

• If a turn light bulb is burned out, the turn signal/hazard warning indicator lights flashing speed increases.

Construction

• Displayed in the instrument cluster.

Operation

Turn light system

1. When the turn switch is moved to the LH or RH position with the ignition switched ON (engine off or on), the start stop unit sends (1) a turn switch LH or RH signal to the front body control module (FBCM) via CAN communication.

2. The front body control module (FBCM) sends (2) the turn switch LH or RH signal to the instrument cluster as a turn signal.

3. The instrument cluster turns the transistor on (3) intermittently based on the turn signal.

4. When the transistor is turned on intermittently, the turn signal indicator light flashes (4).

Hazard warning system

1. When the hazard warning switch is turned on, the start stop unit sends (1) a hazard warning switch on signal to the front body control module (FBCM) via CAN communication.

2. The front body control module (FBCM) sends (2) the hazard warning switch on signal to the instrument cluster as a hazard warning indicator signal.

3. The instrument cluster turns the transistor on (3) intermittently based on the hazard warning indicator signal.

4. When the transistor is turned on intermittently, the hazard warning indicator lights flash (4).
