Automatic Light Control

With the Ignition SW turned ON, Current flows to TERMINAL 1 of Automatic Light Control Sensor through ECU-IG fuse. Voltage is applied at all times to TERMINAL 6 of Automatic Light Control Sensor through the Taillight Relay Coil, and to TERMINAL 5 of the Sensor through the Headlight relay coil.

AUTOMATIC LIGHT CONTROL
When the Light Control SW is in Auto Position. If the Automatic Light Sensor detects a decrease in the Ambient Light (To Between 80 And 450 Lux), the Automatic Light Sensor is activated. About 5 seconds after it is activated, Current flows from TERMINAL 4 of the Sensor to TERMINAL 12 of the Light Control SW to TERMINAL 4 to GROUND, Lighting up the Headlight and Taillight.

If the Ambient Light drop below 80 Lux, the Automatic Light Sensor is activated and about 3 seconds later Current flows from TERMINAL 4 of the Sensor to TERMINAL 12 of the Light Control SW --> TERMINAL 4 --> GROUND, Lighting up the Headlight and Taillight.

When the Light Control SW is at Auto position and activation of the Automatic Light Sensor has turned ON the Headlights and Taillights, if the Automatic Light Sensor detects ambient Light above 950 Lux, the Sensor is turned OFF after about 5 seconds. So the Current from TERMINAL 4 of the Sensor to TERMINAL 12 of Light Control SW stop, And the Headlight and Taillight turn OFF.
