Light Auto Turn Off

This system automatically turns OFF the taillight or headlight by the opening/closing Of the driver door, to prevent the lights from remaining lit.

LIGHT AUTO TURN OFF OPERATION
* When headlights are ON
When the ignition SW turned from ON to OFF with the headlights ON (Light control SW at HEAD position), a signal is input to instrument ECU TERMINAL SIG. When the driver door is opened at this time, a signal is input from the door courtesy SW front LH to the instrument ECU TERMINAL DCY. The instrument ECU TERMINAL HRY is controlled to turn OFF the HEAD relay. As a result, the current to the headlight is cut OFF and the light is turned OFF.
* When taillights are ON
When the ignition SW turned from ON to OFF with the taillights ON (Light control SW at TAIL position), a signal is input to instrument ECU TERMINAL SIG. When the driver door is opened at this time, a signal is input from the door courtesy SW front LH to the instrument ECU TERMINAL DCY.
