LIFTGATE LIGHT

id091800011900


Purpose

•  The liftgate lights are used to signal the following conditions to vehicles/people at the rear.
―  Back-up light: Signals that the vehicle is backing up.
―  Taillight: Signals the presence of the vehicle to vehicles/people at the rear during nighttime.

Function

•  The related light turns on according to the operation of each part.

Operation part

Related light
TCM (selector lever)
Back-up light
Light switch (TNS (parking lights))
Taillight


Structure/Construction

•  The liftgate light groups the back-up light bulb.
•  The liftgate light is integrated with the taillight (LED).
Note
•  Fogging or condensation may occur inside the liftgate lights, however, it is a natural phenomenon occurring as a result of a temperature difference between the interior and exterior of the liftgate lights and it does not affect the light performance.
•  Fogging or condensation occurring as a natural phenomenon will dissipate when the temperature inside the liftgate light rises after the back-up light is turned on and a period of time has elapsed.

Operation


Back-up light

1.  When the selector lever is in the R position with the ignition switched ON (engine off or on), the TCM sends (1) an R position signal to the instrument cluster via CAN communication.
2.  When the instrument cluster receives the R position signal, it sends (2) a back-up light on request signal to the rear body control module (RBCM).
3.  When the rear body control module (RBCM) receives the back-up light on request signal, it turns the back-up light on (3).

Taillight

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 (3) the TNS relay on.
4.  When the TNS relay turns on, the taillight is illuminated (4).
