DOOR LOCK CONTROL (TMMK 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.

Door lock control (Lock and unlock) and panic control (Theft alarm and flash) is performed by remote control, without the
ignition key inserted in the door key cylinder, using low±power electrical waves emitted by a transmitter.
1. WIRELESS DOOR LOCK OR UNLOCK NORMAL OPERATION
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
when the lock or unlock button (Transmitter) is pushed, the wireless door lock ECU receives the electrical waves from the
transmitter, causing it to operate.
As a result, the ECU judges whether the door is locked or unlocked based on the signal from the door lock motor and door
unlock detection SW, and sends a signal to the theft deterrent ECU and integration relay to switch the condition from lock to
unlock or vice versa, causing the door lock motor to operate.
2. VISUAL CONFIRMATION OF LOCK OR UNLOCK
If all doors indicate that they are locked after the lock command, parking lights and taillight will flash once. If any door
indicates that it is open after the unlock command, parking lights and taillights will flash twice.
3. WIRELESS DOOR UNLOCK OPERATION
Pushing the unlock button (Transmitter) once, driver's door is unlocked. Furthermore, pushing the button again within 3
seconds, the other doors are unlocked.
4. AUTOMATIC LOCK OPERATION
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
after pushing the button (Transmitter) to unlock all the doors, if a door is not opened within 30 seconds, all the doors will be
automatically relocked.
5. WIRELESS CONTROL STOP FUNCTION
If a door is open (Door courtesy SW on), a signal is input from the door courtesy SW to the wireless door lock ECU, stopping
wireless door lock or unlock.
If the ignition key is in the ignition key cylinder (Unlock warning SW on), the unlock warning SW inputs a signal to the
wireless door lock ECU, stopping wireless door lock or unlock.
6. DOOR LOCK MOTOR PROTECTIVE FUNCTION
If the door lock or unlock condition does not change after wireless door lock or unlock operation, 2 seconds later, the
integration relay ECU sends current three times to the door lock motor. If the door lock condition still has not changed as a
result, the wireless door lock ECU stops reception and stops door lock and unlock function.
7. REMOTE PANIC OPERATION
Panic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once,
theft alarm sounds and headlights and taillight flash. Then, the panic or the unlock button (Transmitter) is pushed once more,
sounding and flashing will stop. Panic will not function when ignition key is in ignition key cylinder.
