SYSTEM DESCRIPTION

1. LIGHTING SYSTEM
a. Illumination control system (Illuminated entry system):
When a door is unlocked through a key or transmitter operation, or if a door is opened or closed, the illuminated entry system turns on the interior light and the ignition key illumination.

1. The multiplex network body ECU receives the following (A).
- Door courtesy switch signal
- Door detection switch signal
- Ignition switch signal

2. The multiplex network body ECU controls the following based on the signals listed in "A".
- Illumination operation signal

3. The multiplex network body ECU controls the on/off and fade-in/fade-out operation of the following.
- Room light assembly No.1
- Ignition key cylinder light
- Map light assembly (convertible only)

b. Battery saver system:
When the ignition switch is turned off and the driver's door is open continuously for 30 minutes, the multiplex network body ECU will turn the illumination operation signal off. As a result, the room light assembly No.1, ignition key cylinder light, taillights, and the headlights will turn off.

1. The multiplex network body ECU receives the following (B).
- Door courtesy switch signal
- Ignition switch signal

2. The multiplex network body ECU controls the following based on the signals listed in "B" (C).
- Illumination operation signal
- HEAD relay operation signal
- TAIL relay operation signal

3. The multiplex network body ECU controls the illuminating period of the following based on the signals listed in "C".
- Room light assembly No.1
- - Ignition key cylinder light
- Headlight (Low)
- Position light (Front and rear)

c. Manual light control system:
This system functions if lights such as the headlights and taillights come on by manual operation of the light control switch.

1. The multiplex network body ECU receives the following (D).
- Light control switch signal
- Headlight dimmer switch signal
- Fog light switch signal

2. The multiplex network body ECU controls the following based on the signals listed in "D" (E).
- HEAD relay operation signal
- TAIL relay operation signal
- DRL relay operation signal
- FOG relay operation signal

3. The multiplex network body ECU controls the on/off operation of the following signals based on the signals listed in "E".
- Headlight (Low)
- Headlight (Hi)
- Position light (Front and Rear)
- Fog light

d. light auto turn off system:
When the headlights and taillights are on through the operation of the automatic light control switch, if the ignition switch is turned off and all doors are closed, this system continues to illuminate the headlights and taillights for approximately 30 seconds, and then turns off the headlights. However, with all the doors locked manually, using the door lock button or using the key or pressing the "LOCK" on the wireless remote will turn the headlights and taillights off immediately.

1. The multiplex network body ECU receives the following (F).
- Door courtesy switch signal
- Ignition switch signal

2. The multiplex network body ECU controls the following based on the signals listed in "F" (G).
- HEAD relay operation signal
- TAIL relay operation signal
- DRL relay operation signal
- FOG relay operation signal

3. The multiplex network body ECU controls the illuminating period of the following based on the signals listed in "G".
- Headlight (Low)
- Headlight (Hi)
- Position light (Front and Rear)
- Fog light

e. Automatic light control system:
When the light control switch is in the AUTO position, the automatic light control sensor detects ambient light and automatically turns the headlights and taillight on or off accordingly.

1. The multiplex network body ECU receives the following (H).
- Light control switch signal
- Automatic light control sensor signal

2. The multiplex network body ECU controls the following based on the signals listed in "H".
- HEAD relay operation signal
- TAIL relay operation signal

3. The multiplex network body ECU controls the on/off operation of the following.
- Headlight (Low)
- Tail light (Front and rear)

f. Daytime running light system:
This system is directly connected to the high-beam headlights and is designed to automatically activate the daytime running lights in order to remain highly visible to other vehicles.

1. The multiplex network body ECU receives the following (I).
- Ignition switch signal
- Generator signal
- Parking brake switch signal
- Light control switch signal

2. The multiplex network body ECU controls the following based on the signals listed in "I".
- DRL relay operation signal

3. The multiplex network body ECU controls the on/off operation of the following.
- Headlight (Hi)

g. High beam indicator on the combination meter is on:
When the light is HI-BEAM, the system turns on the indicator on the combination meter.

1. The multiplex network body ECU receives the following (J).
- Headlight dimmer switch signal

2. The multiplex network body ECU controls the following based on the signals listed in "J".
- High beam indicator signal

3. The multiplex network body ECU controls the on/off operation the following.
- High beam indicator
