Turn Signal/Hazard Warning Indicator Lights

Purpose

• The turn signal/hazard warning indicator lights notify the driver that the turn lights are flashing.

Function

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

Note

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

Structure/Construction

• The turn signal/hazard warning indicator lights are built into the instrument cluster.

Operation

Turn signal indicator light

1. When the turn switch is in the LH or RH position, the instrument cluster sends (1) a turn switch LH signal or turn switch RH signal to the body control module (BCM) via CAN communication.

2. When the body control module (BCM) receives the turn switch LH signal or turn switch RH signal with the main power switched ON (READY off or on), it sends (2) the signal to the instrument cluster as a turn signal/hazard warning indicator lights on signal.

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

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

Hazard warning indicator light

1. When the hazard warning switch turns on, the climate control unit sends (1) a hazard warning switch on signal to the body control module (BCM) via CAN communication.

2. When the body control module (BCM) receives the hazard warning switch on signal, it sends (2) the signal to the instrument cluster as a turn signal/hazard warning indicator lights on signal.

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

4. When the transistor turns on intermittently, the hazard warning indicator light flashes (4).
