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.
