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.

Structure/Construction

•  Type A or Type B is available for the rear combination light.

Type A

•  The rear combination light groups the rear turn light bulb.
•  The rear combination light is integrated with the following parts.
―  Brake light (LED)
―  Brake light/taillight (LED)
―  Taillight (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 it does not affect the light performance.
•  Fogging or condensation occurring as a natural phenomenon will dissipate when the temperature inside the rear combination lights rises after the rear turn lights are turned on and a period of time has elapsed.

Operation


Taillights

1.  When the light switch is moved to the TNS (parking lights) or HEAD position, the start stop unit detects (1) a TNS (parking lights) signal.
2.  The start stop unit sends (2) the TNS (parking lights) signal to the front body control module (FBCM) via CAN communication.
3.  When the front body control module (FBCM) receives the TNS (parking lights) signal, it turns the taillights on (3).

Brake lights

Operation due to brake pedal operation
Without smart city brake support (SCBS)
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 brake lights are turned on (2)
ac9uun00001853
With smart city brake support (SCBS) and without 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 while the smart city brake support (SCBS) is not operating, the brake light turns on (2).
ac9uun00001854
With smart brake support (SBS)
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, a brake switch (No.1 signal) on signal is input (2) to the brake light unit.
3.  When the brake light unit receives a brake switch (No.1 signal) on signal, it supplies (3) current to the brake lights.
4.  The brake lights turn on (4).

Operation due to operation request signal from rear body control module (RBCM)
Note
•  For the operation conditions, refer to the [SMART CITY BRAKE SUPPORT [FORWARD] (SCBS F)], [SMART CITY BRAKE SUPPORT [REVERSE] (SCBS R)], and [SMART BRAKE SUPPORT (SBS)]. (See SMART CITY BRAKE SUPPORT [FORWARD] (SCBS F).) (See SMART CITY BRAKE SUPPORT [REVERSE] (SCBS R).) (See SMART BRAKE SUPPORT (SBS).)
With smart city brake support (SCBS) and without smart brake support (SBS)
1.  When all the operation conditions are met, the rear body control module (RBCM) turns the transistor on (1) in the rear body control module (RBCM).
2.  When the transistor in the rear body control module (RBCM) turns on, the brake light relay turns on (2).
3.  When the brake light relay turns on, the brake lights turns on (3).
ac9uun00001856
With smart brake support (SBS)
1.  When all the operation conditions are met, the rear body control module (RBCM) turns the transistor on (1) in the rear body control module (RBCM).
2.  When the transistor in the rear body control module (RBCM) turns on, the transistor A in the brake light unit turns on (2).
3.  When the transistor A in the brake light unit turns on, the transistor B in the brake light unit turns on (3).
4.  When the transistor B in the brake light unit turns on, current flows (4) to the brake lights.
5.  The brake lights turn on (5).

Rear turn light

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 detects (1) a turn switch LH or RH signal.
2.  The start stop unit sends (2) the turn switch LH or RH signal to the front body control module (FBCM) via CAN communication as a turn light LH or RH signal.
3.  When the front body control module (FBCM) receives the turn light LH or RH signal, it flashes (3) the rear turn light (LH) or (RH).

Hazard warning system
1.  When the hazard warning switch is on (1), the start stop unit detects (2) a hazard warning switch on signal.
2.  The start stop unit sends (3) the hazard warning switch on signal to the front body control module (FBCM) via CAN communication as a turn light LH and RH signals.
3.  When the front body control module (FBCM) receives the turn light LH and RH signals, it flashes (4) the rear turn lights (LH) and (RH).
