Door Lock Control
The current always flows to TERMINAL 1 of the integration relay through the DOOR fuse.
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) 9 or (A) 7 of the integration relay and causes the relay to function. The current flows from TERMINAL 1 of the
relay to TERMINAL 2 to the door lock motors to TERMINALS (A) 1 and 3 of the relay to TERMINAL 9 to GROUND and the
door lock motors locks the door.
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) 8, (A) 6 or (A) 5 of the integration relay and causes the relay to function. The current flows from TERMINAL 1
of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND
and the door lock motors unlocks the door.
3. Double Operation Unlock Operation
When the door key lock and unlock SW LH is turned to the unlock side, only the driver’s door is unlocked. By turning the
door key lock and unlock SW LH to the unlock side, a signal is input to TERMINAL (A) 6 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 3 of the integration relay to
the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 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 the ignition key in the 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 1 of the integration relay to TERMINALS (A) 1 and 3 to the door lock motors to
TERMINAL 2 of the relay to TERMINAL 9 to GROUND and unlocks all the doors.
∗
Operating door lock control SW or door key lock and unlock SW
With the ignition key in the 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 unlocked by the function of SW contained in motors,
and the signal is input to TERMINAL (A) 19 of the relay. According to this input signal, the current flows from TERMINAL
1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to
GROUND and unlocks all the doors.
∗
In case of key less lock
With the ignition the key in the cylinder (Unlock warning SW on), when the unlock function is disturbed, for example
pushing the door lock knob etc., the door holds on lock condition. After closing the door after, door courtesy SW inputs
the signal into TERMINAL 5 or 6 or (A) 13 of the integration relay. By this input signal, the relay works and current flows
from TERMINAL 1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to
TERMINAL 9 to GROUND and unlocks all the doors.
