Automatic light control is designed for turning taillights and headlights on/off automatically according to the surroundings
brightness when the light control SW is on AUTO position under the condition that the ignition SW is on.
Automatic Light Control Operation
When the surrounding darkens (Darker than the value set for taillight lightning), taillight is automatically turned on under the
condition that the ignition SW is on with the light control SW being on AUTO position. When further darkens (Darker than the
value set for headlight lightning), the headlight is automatically turned on.
In addition, if the brightness reaches the value set for turning the each light off, each light is turned off.

With the ignition SW turned on, the current flows to TERMINAL (A) 5 of the body ECU through IG1 fuse.
Voltage is applied at all times to TERMINAL (A) 7 of the body ECU through the TAILLIGHT relay. Coil side, and to
TERMINAL (C) 3 through the HEAD LAMP relay coil side (w/o daytime running light) or through the DRL NO.2 relay (w/
daytime running light).
1. Normal Lighting Operation

With the light control SW turned to TAIL position, a signal is input into TERMINAL (B) 18 of the body ECU. Due to this signal,
the current flowing to TERMINAL (A) 7 of the body ECU flows to TERMINAL (B) 18 to TERMINAL 14 of the light control SW
to TERMINAL 16 to GROUND, and TAILLIGHT relay causes taillights to turn on.

With the light control SW turned to HEAD position, a signal is input into TERMINALS (B) 17 and (B) 18 of the body ECU. Due
to this signal, the current flowing to TERMINAL (C) 3 of the body ECU flows to TERMINAL (B) 17 to TERMINAL 13 of the
light control SW to TERMINAL 16 to GROUND in the headlight circuit, and causes TAILLIGHT and HEAD LAMP (w/o
daytime running light) or DRL NO.2 relay (w/ daytime running light) to turn the lights on. The taillight circuit is same as above.
2. Light Auto Turn Off Operation
With light on and ignition SW turned off (Input signal goes to TERMINAL (A) 5 of the body ECU), when the driver's door is
opened (Input signal goes to TERMINAL (C) 11 of the body ECU), the ECU operates and the current is cut off which flows
from TERMINAL (A) 7 of the body ECU to TERMINAL (B) 18 in taillight circuit and from TERMINAL (C) 3 to TERMINAL (B)
17 in headlight circuit.
As a result, all lights are turned off automatically.
