Light Auto Turn Off

This system automatically turns off the taillights and/or headlights when the driver door is opened and closed to prevent the lights from remaining lit.

• Taillights ON -  If the ignition switch is turned from ON to OFF with the taillights turn on (the light control switch is set at TAIL), the signal is input to terminal IG of the anti-theft ECU. See WIRING DIAGRAMS . At this time, if the driver door is opened, the signal is input from the front LH door courtesy switch to terminal DCTY of the body ECU. After that, terminal TAIL of the anti-theft ECU is controlled through communication control of the body ECU etc. to turn off the TAIL relay. As a result, the current flowing into the taillights is cut off to turn off the taillights.
• Taillights and Headlights ON -  If the ignition switch is turned from ON to OFF with the taillights and headlights turned on (the light control switch is set at HEAD or AUTO), the signal is input to terminal IG of the anti-theft ECU. See WIRING DIAGRAMS . At this time, if any door is opened, the signal is input from the door courtesy switch to the body ECU. During this operation, the taillights and headlights remain lit. When all doors and the luggage door (sedan) or back door (wagon) are closed, the taillights and headlights are turned on for 30 seconds, through communication control of the body ECU etc. After the set time has elapsed, a signal is input to terminal TAIL and HEAD of the anti-theft ECU, to turn off the TAIL relay and HEAD LP relay. As a result, the current flowing into the taillights and headlights is cut off to turn off the taillights and headlights.

If any door is opened during above operation, the taillights and headlights light up for 30 seconds again, and then go off after all the doors have been closed. Additionally, if the vehicle is locked using the wireless door lock operation (lock operation) while the taillights and headlights are being turned on for 30 seconds, the taillights and headlights go off immediately.
