Light Auto Turn Off System

With the ignition SW turned ON, the current flows to TERMINAL 7 of the integration relay through GAUGE fuse.

Voltage is applied at all times to TERMINAL (A) 5 of the integration relay through the taillight relay (Coil side), and to TERMINAL (A) 6 through the HEAD relay (Coil side).

1. NORMAL LIGHTING OPERATION
Turn taillight ON
With light control SW turned to TAIL position, a signal is input into TERMINAL (A) 4 of the integration relay. Due to this signal, the current flowing to TERMINAL (A) 5 of the relay flows to TERMINAL (A) 4 to TERMINAL 3 of the light control SW to TERMINAL 4 to GROUND and taillight relay causes taillight to turn ON.

Turn headlight ON
With light control SW turned to HEAD position, a signal is input into TERMINALS (A) 4 and (A) 7 of the integration relay. Due to this signal, the current flowing to TERMINAL (A) 6 of the relay flows to TERMINAL (A) 7 to TERMINAL 13 of the light control SW to TERMINAL 4 to GROUND in the headlight circuit, and causes taillight and HEAD relay to turn ON. The taillight circuit is same as above.

2. LIGHT AUTO TURN OFF OPERATION
With lights ON and ignition SW turned OFF (Input signal goes to TERMINAL 7 of the relay), when door on driver's side is opened (Input signal goes to TERMINAL 6 of the relay), the relay operates and the current is cut off which flows from TERMINAL (A) 5 of the relay to TERMINAL (A) 4 in taillight circuit and from TERMINAL (A) 6 to TERMINAL (A) 7 in headlight circuit.

As a result, all lights are turned OFF automatically.
