LIFTGATE LIGHT
id091800706200
Purpose
• The liftgate lights are used to signal the following conditions to vehicles/people at the rear.
-
― Back-up lights: Signals that the vehicle is backing up.
― Taillights: Signals the presence of the vehicle during nighttime. (With taillight (liftgate light))
Function
• The back-up lights are illuminated in conjunction with the selector lever operation.
• The taillights are illuminated in conjunction with the light switch operation (TNS (parking lights)). (With taillight (liftgate light))
Structure/Construction
• The liftgate light is integrated with the following parts.
-
― Back-up light (LED)
― Taillight (LED) (with taillight (liftgate light))
-
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 has no effect on the light performance. Fogging or condensation will dissipate when the temperature inside the liftgate lights rises after the back-up light is illuminated and a period of time has elapsed.
Operation
Taillights (with taillight (liftgate light))
1. When the light switch is in the TNS (parking lights) position, the instrument cluster detects (1) a TNS (parking lights) signal.
2. The instrument cluster sends (2) the TNS (parking lights) signal to the body control module (BCM) via CAN communication.
3. When the body control module (BCM) receives the TNS (parking lights) signal, it sends (3) a TNS (parking lights) on request signal to the electrical supply unit (ESU) via CAN communication.
4. When the electrical supply unit (ESU) receives the TNS (parking lights) on request signal, it turns the taillights on (4).
Back-up lights
-
1. When the selector lever is in the R position, the selector lever sends (1) an R position signal to the PCM via CAN communication.
2. When the PCM receives the R position signal, it sends (2) the signal to the body control module (BCM) via CAN communication.
3. When the body control module (BCM) receives the R position signal with the main power switched ON (READY off or on), it sends (3) a back-up light on request signal to the electrical supply unit (ESU) via CAN communication.
4. When the electrical supply unit (ESU) receives the back-up light on request signal, it turns the back-up lights on (4).
