LEAVING HOME LIGHT SYSTEM

id091800006400

Outline

• When the door unlock operation is performed using the remote transmitter with the ignition switched off and the light switch in the HEAD or TNS position^*1, the leaving home light system turns on the headlights LO and TNS for a specified time.

• When approaching 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 and TNS on.

*1 :For the headlight LO and TNS illumination conditions with the ignition switched off, refer to the [EXTERIOR LIGHTING SYSTEM]. (See EXTERIOR LIGHTING SYSTEM.)

Function

Leaving home light off timer function

• When the front body control module (FBCM) receives a door unlock request signal from the remote transmitter with the light switch in the TNS or HEAD position and the ignition switched off, it turns the headlights LO and the TNS on and operates the leaving home light off timer.

• When the time on the leaving home light off timer (30 s) has elapsed, the front body control module (FBCM) turns the headlights LO and the TNS off.^*2

• When the front body control module (FBCM) receives a door lock request signal from the remote transmitter during leaving home light off timer operation, it turns the headlights LO and the TNS off.^*2

*2 :If the light switch is in the TNS position, the TNS is not turned off.

Personalization features

• The leaving home light system can be switched between operable and inoperable (initial setting is ON). For details on the personalization features, refer to the [LIGHTING SYSTEM PERSONALIZATION]. (See LIGHTING SYSTEM PERSONALIZATION.)

Operation

• The leaving home light function operates when all of the following conditions are met.

Leaving home light operation conditions

― IG1 relay is off (ignition is switched off)

― Light switch at TNS or HEAD position

― Door unlock request signal is received by remote transmitter

Light switch at HEAD position

1. When the unlock button on the remote transmitter is pressed, the start stop unit detects (1) a door unlock request signal. For details on the door lock/unlock operation using the remote transmitter, refer to the [KEYLESS ENTRY SYSTEM]/[ADVANCED KEYLESS ENTRY SYSTEM]. (See KEYLESS ENTRY SYSTEM.) (See ADVANCED KEYLESS ENTRY SYSTEM.))

2. The start stop unit sends (2) the light switch signal to the front body control module (FBCM) via CAN communication. In addition, it sends (2) the door unlock signal to the front body control module (FBCM) via the rear body control module (RBCM) and instrument cluster.

3. When the front body control module (FBCM) receives the light switch signal with all operation conditions met, it turns the transistor and headlight LO relay on (3) and illuminates the TNS, parking lights, signature wing illumination (with signature wing illumination), and headlights (4).

4. After the leaving home light off timer has elapsed, the front body control module (FBCM) turns the transistor and headlight LO relay off (5) and turns the TNS, parking lights, signature wing illumination (with signature wing illumination), and headlights off (6).

Light switch at TNS position

3. When the front body control module receives the light switch position signal with all operation conditions met, it turns the headlight LO relay on (3) and turns the headlights LO on (4).

4. After the leaving home light off timer has elapsed, the front body control module (FBCM) turns the headlight LO relay off (5) and turns the headlights LO off (6).
