SYSTEM DESCRIPTION
1. LIGHTING SYSTEM
(a) Illumination control system (Illuminated entry
system):
When the doors are unlocked by a key or
transmitter operation, or when a door is opened or
closed, the illuminated entry system turns on the
room light, map light, foot light and ignition key
cylinder light*1 or transponder key amplifier*2.
(1) The main body ECU receives the following
signals (A).
• Door courtesy switch signal
• Door detection switch signal
• Ignition switch signal
(2) The main body ECU controls the following signal
based on the signals listed in A.
• Illumination operation signal
(3) The main body ECU controls the on/off and
fade-in/fade-out operation of the following parts.
•Room light
• Map light
•Foot light
• Ignition key cylinder light*1 or transponder
key amplifier*2
HINT:
*1: w/o Engine immobiliser system
*2: w/ Engine immobiliser system
(b) Battery saver system:
When the ignition switch is turned off and any of the
doors is open continuously for 20 minutes, the main
body ECU turns the illumination operation signal off.
As a result, the room light, map light, foot light and
ignition key cylinder lights*1 or transponder key
amplifier*2 turn off.
HINT:
*1: w/o Engine immobiliser system
*2: w/ Engine immobiliser system
(1) The main body ECU receives the following
signals (B).
• Door courtesy switch signal
• Ignition switch signal
(2) The main body ECU controls the following signal
based on the signals listed in B (C).
• Illumination operation signal
(3) The main body ECU controls the illumination
period of the following parts based on the
signals listed in C.
•Room light
• Map light
•Foot light
• Ignition key cylinder light*1 or transponder
key amplifier*2
HINT:
*1: w/o Engine immobiliser system

*2: w/ Engine immobiliser system
(c) Manual light control system:
This system functions when lights such as the
headlights and taillights are illuminated by manual
operation of the light control switch.
(1) The main body ECU receives the following
signals (D).
• Light control switch signal
• Headlight dimmer switch signal
• Front fog light switch signal
(2) The main body ECU controls the following
signals based on the signals listed in D (E).
• Headlight relay operation signal
• Taillight relay operation signal
• Daytime running light No. 2 relay operation
signal
• Daytime running light No. 3 relay operation
signal
• Daytime running light No. 4 relay operation
signal
• Front fog light relay operation signal
(3) The main body ECU controls the on/off
operation of the following parts based on the
signals listed in E.
• Headlight (LOW)
• Headlight (HIGH)
• Side marker light (front and rear)
• Front fog light
(d) Light auto turn off system:
When the headlights and taillights are illuminated by
the operation of the light control switch, if the
ignition switch is turned OFF, this system continues
illuminating the headlights and taillights for
approximately 30 seconds, and then turns off the
lights. However, when all the doors are locked
manually, using the door lock button, using the key
or pressing LOCK on the transmitter turns the
headlights and taillights off immediately.
(1) The main body ECU receives the following
signals (F).
• Door courtesy switch signal
• Ignition switch signal
(2) The main body ECU controls the following
signals based on the signals listed in F (G).
• Headlight relay operation signal
• Taillight relay operation signal
• Daytime running light No. 2 relay operation
signal
• Daytime running light No. 3 relay operation
signal
• Daytime running light No. 4 relay operation
signal
• Front fog light relay operation signal

(3) The main body ECU controls the illumination
period of the following parts based on the
signals listed in G.
• Headlight (LOW)
• Headlight (HIGH)
• Side marker light (front and rear)
• Front fog light
(e) 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 increase the
visibility of the vehicle.
(1) The main body ECU receives the following (H).
• Ignition switch signal
• Engine speed
• Parking brake switch signal
• Light control switch signal
(2) The main body ECU controls the following signal
based on the signals listed in H (I).
• Daytime running light No. 2 relay operation
signal
(3) The main body ECU controls the on/off
operation of the following part based on the
signal listed in I.
• Headlight (HIGH)
