COMING HOME LIGHT

COMING HOME LIGHT

id091800015700



Outline

• When the FLASH-TO-PASS operation is performed with the ignition switched off or ACC, the coming home light 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 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 BCM 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 BCM turns the headlights LO off.


Coming home light off timer function

• The BCM 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 BCM turns the headlights LO off.


Personalization features

• The coming home light off timer setting for the coming home light can be changed (initial setting is [30 seconds.]/[30 seconds]). For details on the personalization features, refer to the [LIGHTING SYSTEM PERSONALIZATION].

Note
• The BCM disables the coming home light control during the auto light off timer illumination time count.



Operation


Coming home light stand-by operation

• When a FLASH-TO-PASS signal (light switch 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
― Ignition is switched off or ACC
― Coming home light off timer (personalization setting) not set at [0 seconds.]/[Off]
― Not during auto light off timer illumination time count

1.When the dimmer switch is in the passing position, the instrument cluster detects (1) a flash-to-pass signal.

2.The instrument cluster sends (2) the flash-to-pass signal to the body control module (BCM) via CAN communication.

3.When the body control module (BCM) receives the flash-to-pass signal with the operation conditions met, it turns the headlights LO on (3) and the system 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 body control module (BCM) 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, it operates (2) the coming home light off timer.

2.After the coming home light off timer has elapsed, the body control module (BCM) sends (3) a headlight LO off signal to the light control module.

3.When the light control module receives a headlight LO off signal from the body control module (BCM), it turns the headlights LO off (4).
