Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also
flows through the rear lights warning light to TERMINAL 4 of the light failure sensor.
STOP LIGHT DISCONNECTION WARNING
When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the
current flowing from TERMINAL 7 of the light failure sensor to TERMINAL 2 and 1 changes, so the light failure sensor
detects the disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear
lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the
warning circuit on holding and the warning light on until the ignition SW is turned off.

TAILLIGHT
When the light control SW is turned to TAIL or HEAD position. The current flows to TERMINAL 3 of the light failure sensor
through the TAIL fuse.
When the ignition SW is turned on, the current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and
also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor.
TAILLIGHT DISCONNECTION WARNING
With the ignition SW on and the light control SW turned to TAIL or HEAD position, if the taillight circuit is open, the light failure
sensor detects the failure by the change in current flowing from TERMINAL 3 of the light failure sensor to TERMINAL 9, and
the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear
lights warning light on, which remains on until the light control SW is turned off

DOOR LOCK CONTROL (TMC MADE)
Current always flows to TERMINAL (A) 13 (w/o theft deterrent system), (B) 1 (w/ theft deterrent system) of the integration
relay through the DOOR fuse.
When the ignition SW is turned on, the current flowing through the GAUGE Fuse flows to TERMINAL 7 of the integration
relay to TERMINAL (A) 12 (w/o theft deterrent system), (B) 3 (w/ theft deterrent system) to the power relay (Coil side) to
GROUND.
1. MANUAL LOCK OPERATION
When the door lock control SW or door key lock and unlock SW are operated to LOCK position, a lock signal is input to
TERMINAL (A) 1 or (A) 3 (w/o theft deterrent system), (B) 16 or (B) 18 (w/ theft deterrent system) of the integration relay and
causes the relay to function. Current flows from TERMINAL (A) 13 (w/o theft deterrent system), (B) 1 (w/ theft deterrent
system) of the relay to (A) 6 (w/o theft deterrent system), (B) 12 (w/ theft deterrent system) to TERMINAL 2 of the door lock
motors to TERMINAL 3 to TERMINAL (A) 7 (w/o theft deterrent system), (B) 11 and (B) 25 (w/ theft deterrent system) of the
relay to TERMINAL 10 to GROUND and the door lock motor causes the door to lock.
2. MANUAL UNLOCK OPERATION
When the door lock control SW or door key lock and unlock SW are operated to UNLOCK position, an unlock signal is input
to TERMINAL (A) 2, (A) 4 or (A) 5 (w/o theft deterrent system), (B) 17, (B) 19 or (B) 20 (w/ theft deterrent system) of the
integration relay and causes the relay to function. Current flows from TERMINAL (A) 13 (w/o theft deterrent system), (B) 1 (w/
theft deterrent system) of the relay to TERMINAL (A) 7 (w/o theft deterrent system), (B) 11 and (B) 25 (w/ theft deterrent
system) to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL (A) 6 (w/o theft Deterrent system), (B) 12 (w/
theft deterrent system) of the relay to TERMINAL 10 to GROUND and door lock motors causes door to unlock.
3. DOUBLE OPERATION UNLOCK OPERATION
When the door key lock and unlock SW front LH is turned to the unlock side, only the driver's door is mechanically unlocked.
Turning the door key lock and unlock SW front LH to the unlock side causes a signal to be input to TERMINAL (A) 4 (w/o
theft deterrent system), (B) 19 (w/ theft deterrent system) of the relay, and if the signal is input again within 3 seconds by
turning the SW to the unlock side again, current flows from TERMINAL (A) 7 (w/o theft deterrent system), (B) 11 and (B) 25
(w/ theft deterrent system) of the integration relay to TERMINAL 3 of the door lock motors to TERMINAL 2 of the door lock
motors to TERMINAL (A) 6 (w/o theft deterrent system), (B) 12 (w/ theft deterrent system) of the relay to TERMINAL 10 to
GROUND, causing the door lock motors to operate and unlock the doors.
4. IGNITION KEY REMINDER OPERATION
*Operating door lock knob (Operation of door lock motors)
With ignition key in cylinder (Unlock warning SW on), when the door is opened and locked using door lock knob (Door
lock motor), the door is locked once but each door is unlocked soon by the function of the relay. As a result, the current
flows from TERMINAL (A) 13 (w/o theft deterrent system), (B) 1 (w/ theft deterrent system) of the integration relay to
TERMINAL (A) 7 (w/o theft deterrent system),(B) 11 and (B) 25 (w/ theft deterrent system) to TERMINAL 3 of the door
lock motors to TERMINAL 2 of the door lock motors to TERMINAL (A) 6 (w/o theft deterrent system), (B) 12 (w/ theft
deterrent system) of the relay to TERMINAL 10 to GROUND and causes all the doors to unlock.
*Operating door lock control SW or door key lock and unlock SW
With ignition key in cylinder (Unlock warning SW on), when the door is opened and locked using door lock control SW or
key SW, the door is locked once but each door is unlock by the function of SW contained in motors, which the signal is
input to TERMINAL (A) 9 or (A) 10 (w/o theft deterrent system), (B) 5 or (B) 7 (w/ theft deterrent system) of the relay.
According to this input signal, the current in ECU flows from TERMINAL (A) 13 (w/o theft deterrent system), (B) 1 (w/
theft deterrent system) of the relay to TERMINAL (A) 7 (w/o theft deterrent system), (B) 11 and (B) 25 (w/ theft deterrent
system) to TERMINAL 3 of the door lock motors to TERMINAL 2 of the door lock motors to TERMINAL (A) 6 (w/o theft
deterrent system), (B) 12 (w/ theft deterrent system) of the relay to TERMINAL 10 to GROUND and causes all the doors
to unlock.
*In case of key less lock
With ignition key in cylinder (Unlock warning SW on), when the unlock function is disturbed more than 0.2 seconds, for
example pushing the door lock knob etc., the door holds on lock condition. Closing the door after, door courtesy SW
inputs the signal into TERMINAL 6 or (A) 8 (w/o theft deterrent system), (B) 6 (w/ theft deterrent system) of the
integration relay. By this input signal, the ECU works and current flows from TERMINAL (A) 13 (w/o theft deterrent
system), (B) 1 (w/ theft deterrent system) of the relay to TERMINAL (A) 7 (w/o theft deterrent system), (B) 11 and (B) 25
(w/ theft deterrent system) to TERMINAL 3 of the door lock motors to TERMINAL 2 of the door lock motors to
TERMINAL (A) 6 (w/o theft deterrent system), (B) 12 (w/ theft deterrent system) of the relay to TERMINAL 10 to
GROUND and causes all the doors to unlock.
