Purpose

― Rear turn lights: Signals a left or right turn of the vehicle.

― Brake lights: Signals a vehicle deceleration or stop.

― Taillights: Signals the presence of the vehicle to vehicles/people at the rear during nighttime.

― Rear side marker lights: Signals the presence of the vehicle to vehicles/people at the adjacent rear during nighttime.

Function

Structure/Construction

― Rear turn light (LED)

― Brake light/taillight (LED)

― Taillight (LED)

― Rear side marker light (LED)

Note

• Fogging or condensation on the inside of the rear combination lights may occur, however, it is a natural phenomenon occurring as a result of a temperature difference between the interior and exterior of the combination lights and has no effect on the light performance. Fogging or condensation will dissipate when the temperature inside the rear combination lights rises after the rear turn lights are illuminated and a period of time has elapsed.

Operation

Rear turn light

Turn light system

1. When the turn switch is in the LH or RH position, the instrument cluster detects (1) a turn switch LH signal or turn switch RH signal.

2. The instrument cluster sends (2) the turn switch LH signal or turn switch RH signal to the body control module (BCM) via CAN communication.

3. When the body control module (BCM) receives the turn switch LH signal or turn switch RH signal with the ignition switched ON (engine off or on), it sends (3) a turn switch LH flash request signal or turn switch RH flash request signal to the electrical supply unit (ESU) via CAN communication.

4. When the electrical supply unit (ESU) receives a rear turn light (LH) flash request signal or rear turn light (RH) flash request signal, it flashes (4) the rear turn light (LH) or rear turn light (RH).

Hazard warning system

1. When the hazard warning switch turns on, the instrument cluster detects (1) a hazard warning switch on signal.

2. The instrument cluster sends (2) the hazard warning switch on signal to the body control module (BCM) via CAN communication as a turn switch LH signal and turn switch RH signal.

3. When the body control module (BCM) receives the turn switch LH signal and turn switch RH signal, it sends (3) a rear turn light (LH) flash request signal and rear turn light (RH) flash request signal to the electrical supply unit (ESU) via CAN communication.

4. When the electrical supply unit (ESU) receives the rear turn light (LH) flash request signal and rear turn light (RH) flash request signal, it flashes (4) the rear turn light (LH) or rear turn light (RH).

Brake light

Operation due to brake pedal operation

1. When the brake pedal is depressed, the brake switch (No.1 signal) turns on (1).

2. When the brake switch (No.1 signal) turns on, the electrical supply unit (ESU) detects (2) a brake switch (No.1 signal) on signal.

3. When the electrical supply unit (ESU) detects the brake switch (No.1 signal) on signal, it turns the brake lights on (3).

Operation due to operation request signal from BCM

1. When the operation conditions are met, the body control module (BCM) turns on (1) the transistor inside the body control module (BCM).

Note

• For the operation conditions, refer to the followings:

― Smart brake support (SBS) (See SMART BRAKE SUPPORT (SBS).)

― Smart brake support [Rear] (SBS-R) (See SMART BRAKE SUPPORT [REAR] (SBS-R).)

― Smart brake support [Rear Crossing] (SBS-RC) (See SMART BRAKE SUPPORT [REAR CROSSING] (SBS-RC).)

2. When the transistor inside the body control module (BCM) turns on, the electrical supply unit (ESU) turns on (2) transistor A inside the electrical supply unit (ESU).

3. When transistor A turns on, the electrical supply unit (ESU) turns transistor B on (3).

4. When transistor B inside the electrical supply unit (ESU) turns on, the brake lights turn on (4).

Taillight

1. When the light switch is in the TNS (parking lights) position with the ignition switched ON (engine off or on), the instrument cluster detects (1) a TNS (parking lights) signal.

2. The instrument cluster sends (2) the TNS signal to the body control module (BCM) via CAN communication.

3. When the BCM receives the TNS signal, the BCM sends (3) the TNS signal to the electrical supply unit (ESU) via CAN communication.

4. When the electrical supply unit (ESU) receives the TNS request signal, it turns the taillights on (4).

Rear side marker light

1. When the light switch is moved to the TNS (parking lights) or HEAD position, the instrument cluster detects (1) a TNS (parking lights) signal.

2. The instrument cluster sends (2) the TNS (parking lights) signal to the BCM via CAN communication.

3. When the BCM receives the TNS (parking lights) signal, the BCM sends (3) the TNS (parking lights) signal to the electrical supply unit (ESU) via CAN communication.

4. When the electrical supply unit (ESU) receives the TNS (parking lights) request signal, the rear side marker light is illuminated (4).
