SYSTEM OUTLINE
Current always flows to TERMINAL (A) 15 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) 24 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 is operated to LOCK position, a lock signal is input to
TERMINAL (A) 3 or (A) 5 of the integration relay and activates the relay. Current flows from TERMINAL (A) 15 of the
integration relay to TERMINAL (A) 1 to TERMINAL 2 of the door lock motors (Front LH, RH and back door) and (A) 2 or (A)
1 of the slide door junction connectors (LH and RH) to TERMINAL 3 (Front LH and RH), 1 (Back door) and (A) 1 or (A) 3
(Slide door LH and RH) to TERMINAL (A) 2 or (A) 14 of the integration relay to TERMINAL 10 to GROUND and the door lock
motors lock all doors.
2. MANUAL UNLOCK OPERATION
When the door lock control SW or door key lock and unlock SW is operated to UNLOCK position, an unlock signal is input to
TERMINAL (A) 4, (A) 6 or (A) 7 of the integration relay and activates the relay. Current flows from TERMINAL (A) 15 of the
integration relay to TERMINAL (A) 2 or (A) 14 to TERMINAL 3 of the front door motors (LH and RH), 1 of the back door
motor and (A) 1 or (A) 3 of the slide door junction connectors (LH and RH) to TERMINAL 2 of the door motors (Front LH, RH
and back door) and (A) 2 or (A) 1 (Slide door LH and RH) to TERMINAL (A) 1 of the integration relay to TERMINAL 10 to
GROUND and door lock motors unlock all doors.
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.
By turning the door key lock and unlock SW front LH to the unlock side, a signal is input to TERMINAL (A) 6 of the
integration relay. If the signal is input to TERMINAL (A) 6 again within 3 seconds by turning the SW to the unlock side again,
current flows from TERMINAL (A) 2 or (A) 14 to TERMINAL 3 of the front door motors (LH and RH), 1 of the back door motor
and (A) 1 or (A) 3 of the slide door junction connectors (LH and RH) to TERMINAL 2 of the door motors (Front LH, RH and
back door) and (A) 2 or (A) 1 (Slide door LH and RH) to TERMINAL (A) 1 of the integration relay to TERMINAL 10 to
GROUND, operating the door lock motors to unlock all doors.
4. IGNITION KEY REMINDER OPERATION
Operating door lock knob (Operation of door lock motors)
In the case that the door is opened and locked using the door lock knob (door lock motor), with the ignition key
remaining in the cylinder, this relay unlocks the doors within a few seconds. Accordingly, the current flows from
TERMINAL (A) 15 of the integration relay to TERMINAL (A) 2 or (A) 14 to TERMINAL 3 of the front door motors (LH and
RH), 1 of the back door motor and (A) 1 or (A) 3 of the slide door junction connectors (LH and RH) to TERMINAL 2 of
the door motors (Front LH, RH and back door) and (A) 2 or (A) 1 (Slide door LH and RH) to TERMINAL (A) 1 of the
integration relay to TERMINAL 10 to GROUND and unlocks all the doors.
Operating door lock control SW or door key SW
In the case that the door is opened and locked using door lock control SW or key SW, with the ignition key remaining in
the cylinder, the SW in the motors unlock the doors within a few seconds, and a signal is input to TERMINAL (A) 10 or
(C) 10 of the integration relay. According to this input signal, the current flows from TERMINAL (A) 15 of the integration
relay to TERMINAL (A) 2 or (A) 14 to TERMINAL 3 of the front door motors (LH and RH), 1 of the back door motor and
(A) 1 of or (A) 3 the slide door junction connectors (LH and RH) to TERMINAL 2 of the door motors (Front LH, RH and
back door) and (A) 2 or (A) 1 (Slide door LH and RH) to TERMINAL (A) 1 of the integration relay to TERMINAL 10 to
GROUND and unlocks all the doors.
In case of key less lock
When the unlock function is disturbed more than 0.2 seconds, with ignition key in cylinder (Unlock warning SW on), 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 4 or 6 of the integration relay. By this input signal, the integration relay works and the
current flows from TERMINAL (A) 15 of the integration relay to TERMINAL (A) 2 or (A) 14 to TERMINAL 3 of the front
door motors (LH and RH), 1 of the back door motor and (A) 1 or (A) 3 of the slide door junction connectors (LH and RH)
to TERMINAL 2 of the door motors (Front LH, RH and back door) and (A) 2 or (A) 1 (Slide door LH and RH) to
TERMINAL (A) 1 of the integration relay to TERMINAL 10 to GROUND and unlocks all the doors.
5. SIDE DOOR AUTOMATIC LOCK OPERATION
This is the function to lock the sliding door automatically if you lock the driver side door is locked with a key or manual SW
and close the sliding door when the sliding door is open.
