Automatic Light Control
System OutlineWhen the light control SW is set at AUTO, the automatic light control system automatically turns on or off the taillights and headlights depending on the brightness around the vehicle.
Automatic Light Control Operation
The automatic light control sensor converts the intensity of the illumination into frequency and inputs it to the theft deterrent ECU. When the light control SW is set at AUTO, the signal is input to TERMINAL A of the theft deterrent ECU. Through communication control of the body ECU etc., the taillights and headlights are automatically turned on or off.
- Turn on operation
When the theft deterrent ECU receives the frequency signal from the automatic light control sensor and determines that the brightness around the vehicle has decreased below a specified level, TERMINAL TAIL and HEAD of the theft deterrent ECU are controlled through communication control of the body ECU etc. As a result, the taillights and/or headlights light up as the TAIL relay and/or HEAD LP relay are turned on.
- Turn off operation
When the theft deterrent ECU receives the frequency signal from the automatic light control sensor and determines that the brightness around the vehicle has exceeded a specified level, TERMINAL TAIL and HEAD of the theft deterrent ECU are controlled through communication control of the body ECU etc. As a result, the taillights and/or headlights go off as the TAIL relay and/or HEAD LP relay are turned off.
