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.

LIGHT AUTO TURN OFF OPERATION
* Taillights ON
If the ignition SW is turned from ON to OFF with the taillights turned on the light control SW is set at TAIL), the signal is input to TERMINAL SIG of the body ECU. At this time, if the driver door is opened, the signal is input from the front door open detection SW LH to TERMINAL CTY of the driver door ECU. After that, TERMINAL TRLY of the body ECU is controlled through communication control of the body ECU and door ECU etc. to turn off the taillight control 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 SW is turned from ON to OFF with the taillights and headlights turned on the light control SW is set at HEAD), the signal is input to TERMINAL SIG of the body ECU. At this time, if any door is opened, the signal is input from the door open detection SW to TERMINAL CTY of the driver door ECU. During this operation, the taillights and headlights are remained lit. When all doors and the luggage door are closed, the taillights and headlights are turned on for 30 sec., through communication control of the body ECU and door ECU etc. After the set time has elapsed, a signal is input to TERMINAL TRLY and HRLY of the body ECU, to turn off the taillight control 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 sec. again, and then go off after all the doors have been closed.
Additionally, if the vehicle is locked using the wireless door lock operation while the taillights and headlights are being turned on for 30 sec., the taillights and headlights go off immediately.
