COMING HOME LIGHT SYSTEM
id091800006300
Outline
• When the FLASH-TO-PASS operation is performed with the ignition switched off or ACC, the coming home light system turns on the headlights LO for a specified time after leaving the vehicle.
• When leaving the vehicle in a parking lot where the area surrounding the vehicle is dark, the system is used for assuring visibility at the front of the vehicle by turning the headlights LO on.
Function
• The coming home light system controls the headlights LO using the following two functions:
-
― Coming home light stand-by function: Turns on the headlights LO until the user gets out of the vehicle after operating the FLASH-TO-PASS.
― Coming home light off timer function: Operates when the user gets out of the vehicle and closes all of the doors while the coming-home-light stand-by function is operating.
Coming home light stand-by function
-
• When the front body control module (FBCM) receives a FLASH-TO-PASS signal with the ignition switched off or ACC, it turns the headlights LO on. After 3 min have elapsed since going on coming home light stand-by or a FLASH-TO-PASS signal is received during stand-by, the front body control module (FBCM) turns the headlights LO off.
Coming home light off timer function
-
• The front body control module (FBCM) operates the coming home light off timer at the point in time the following conditions occur:
-
― Off signals for all door latch switches (doors closed) are detected after detecting any on signal for the door latch switches (door open) while on coming home light stand-by.
― When any on signal for the door latch switches (door open) is detected, it goes on coming home light stand-by, and then off signals for all door latch switches (doors closed) are detected.
• After the coming home light off timer has elapsed, the front body control module (FBCM) turns the headlights LO off.
Personalization features
-
• The coming home light off timer setting for the coming home light system can be changed (initial setting is
30 s). For details on the personalization features, refer to the [LIGHTING SYSTEM PERSONALIZATION]. (See
LIGHTING SYSTEM PERSONALIZATION.)

Operation
Coming home light stand-by operation
-
• When a FLASH-TO-PASS signal (dimmer switch position signal) is received with all of the following conditions met, it goes on coming home light stand-by.
Coming home light stand-by operation conditions
-
― IG1 relay is off (ignition is switched off or ACC)
― Coming home light off timer (personalization setting) not set at 0 s (OFF)
1. When the dimmer switch position is moved to the FLASH-TO-PASS position, the start stop unit detects (1) a FLASH-TO-PASS signal.
2. The start stop unit sends (2) the FLASH-TO-PASS signal to the front body control module (FBCM) via CAN communication.
3. When the front body control module (FBCM) receives the flash-to-pass signal with all operation conditions met, it turns the headlight LO relay on (3).
4. When the headlight LO relay turns on, the headlights LO turns on (4) and it goes on coming-home-light stand-by.
Coming home light off timer operation
-
• When the following condition is met while on coming home light stand-by, the coming home light off timer operates.
Coming home light off timer operation condition
-
― All off signals for the door latch switches (doors closed) are detected after detecting any on signal for the door latch switches (door open).
1. When the rear body control module (RBCM) detects (1) all off signals for the door latch switches (doors closed) after detecting any on signal for the door latch switches (door open) during coming home light stand-by, the front body control module (FBCM) operates (2) the coming home light off timer.
2. After the coming home light off timer has elapsed, the front body control module (FBCM) turns the headlight LO relay off (3) and turns the headlights LO off (4).
