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 at TAIL position), the signal is input to TERMINAL IG of the body ECU. At this time, if the driver door is opened, the signal is input from the door courtesy SW front LH to TERMINAL CTY of the driver door ECU. After that, TERMINAL TAIL of the body ECU is controlled through communication control of the body ECU and door ECU etc. to turn Off the taillight relay. As a result, the current flowing into the taillights is cut Off to turn Off the taillights.

At this time, if the driver door is opened, the signal is input from the door courtesy SW front LH to TERMINAL CTY of the driver door ECU. After that, TERMINALS TAIL and HEAD of the body ECU is controlled through communication control of the body ECU and door ECU etc. to turn Off the taillight relay and HEAD LAMP relay.
