REAR COMBINATION LIGHT

id091800011800


Purpose

•  The rear combination lights are used to signal the following conditions to vehicles/people at the rear.
―  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.

Function

•  The related light turns on or flashes according to the operation of each switch.

Construction

•  A bulb type or LED type is available for the rear combination light.

Bulb type

•  The rear combination light groups the following parts.
―  Rear turn light bulb
―  Brake light/taillight bulb
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 light bulbs are illuminated and a period of time has elapsed.

LED type

•  The rear combination light groups the rear turn light bulb.
•  The rear combination light is integrated with brake light/taillight (LED).

Operation


Taillights

1.  When the light switch is operated to the TNS position, a light switch TNS signal is input to the start stop unit.

2.  The start stop unit sends the light switch TNS signal to the front body control module (FBCM).

3.  When the front body control module (FBCM) receives the light switch TNS signal, it turns the TNS relay on.

4.  When the TNS relay turns on, the taillights are illuminated.

Brake lights

Operation due to brake pedal operation
Without smart brake support (SBS) and smart city brake support (SCBS)
1.  When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
2.  When the brake switch (No.1 signal) turns on, current flows from the battery to the brake lights.
3.  The brake lights turn on.

Without smart brake support (SBS) and with smart city brake support (SCBS)
1.  When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
2.  When the brake switch (No.1 signal) turns on, current flows from the battery to the brake lights.
3.  The brake lights turn on.
ac5wzn00002942
With smart brake support (SBS)
1.  When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
2.  When the brake switch (No.1 signal) turns on, a brake switch (No.1 signal) on signal is input to the brake light unit.
3.  When the brake light unit receives a brake switch (No.1 signal) on signal, it supplies current to the brake lights.
4.  The brake lights turn on.

Operation due to operation request signal from rear body control module (RBCM)
Note
•  Refer to [SMART BRAKE SUPPORT (SBS)] and [SMART CITY BRAKE SUPPORT (SCBS)] for details. (See SMART BRAKE SUPPORT (SBS).) (See SMART CITY BRAKE SUPPORT [FORWARD] (SCBS F).) (See SMART CITY BRAKE SUPPORT [REVERSE] (SCBS R).)
Without smart brake support (SBS) and with smart city brake support (SCBS)
1.  When the operation conditions are met, the rear body control module (RBCM) turns on the transistor inside the rear body control module (RBCM).
2.  When the transistor inside the rear body control module (RBCM) turns on, the brake light relay turns on.
3.  When the brake light relay turns on, current flows from the battery to the brake lights.
4.  The brake lights turn on.
ac5wzn00002944
With smart brake support (SBS)
1.  When the operation conditions are met, the rear body control module (RBCM) turns on the transistor inside the rear body control module (RBCM).
2.  When the transistor inside the rear body control module (RBCM) turns on, the transistor inside the brake light unit turns on.
3.  When the transistor inside the brake light unit turns on, current flows to the brake lights.
4.  The brake lights turn on.

Rear turn light

Turn light system
1.  When the turn switch is operated to the LH or RH position, a turn LH or RH signal is input to the start stop unit.
2.  The start stop unit sends the turn LH or RH signal to the front body control module (FBCM) via CAN communication.
3.  When the front body control module (FBCM) receives the turn LH or RH signal, the rear turn light (LH) or (RH) is illuminated.
ac5wzn00002946
Hazard warning system
1.  When the hazard warning switch is turned on, a hazard warning signal is input to the start stop unit.
2.  The start stop unit sends a hazard warning signal to the front body control module (FBCM).
3.  When the front body control module (FBCM) receives the hazard warning signal, the rear turn lights (RH) and (LH) flash.
