DOOR LOCK CONTROL
SYSTEM OUTLINE
Current always flows to TERMINAL POWER of the body ECU through the POWER fuse.
1. MANUAL LOCK OPERATION
To push door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to TERMINAL L1 or L2
of the body ECU and causes the body ECU to function. Current flows from TERMINAL POWER of the body ECU to
TERMINAL ACT+ to TERMINAL 2 of the door lock motors to TERMINAL 3 to TERMINAL ACT- and ACTD of the body ECU
to TERMINAL GND to GROUND and the door lock motor causes the door to lock.
2. MANUAL UNLOCK OPERATION
To push door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to TERMINAL
UL1, UL2 or UL3 of the body ECU and causes the body ECU to function. Current flows from TERMINAL POWER of the
body ECU to TERMINAL ACT- and ACTD to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL ACT+ of
the body ECU to TERMINAL GND to GROUND and the door lock motor causes the door to unlock.
3. IGNITION KEY REMINDER OPERATION
Operating door lock knob (in door lock motor operation)
With ignition key in cylinder (Unlock warning SW on), when the driver's door is opened (Door courtesy SW on) and
locked using the driver's door lock knob (Door lock motor), the driver's door is locked once but all door is unlocked soon
by the function of the body ECU. As a result, the current flows from TERMINAL POWER of the body ECU to TERMINAL
ACT- and ACTD to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL ACT+ of the body ECU to
TERMINAL GND to GROUND and causes all the door to unlock.
For front passenger's door, as driver's door lock knob operated, the door lock motor is operated.
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 (Door courtesy SW on) and locked using
door lock control SW or door key lock and unlock SW, all door lock is locked once but all door is unlocked by the
function of SW contained in motor, which inputs the signal to TERMINAL LSWD or LSWP of the body ECU. According to
this input signal, the current in the body ECU flows from TERMINAL POWER of the body ECU to TERMINAL ACT- and
ACTD to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL ACT+ of the body ECU to TERMINAL
GND to GROUND and causes all the doors to unlock.
4. 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 unlocked. Turning the
door key lock and unlock SW front LH to the unlock side causes a signal to be input to TERMINAL UL3 of the body ECU,
and if the signal input again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL
POWER of the body ECU to TERMINAL ACT- and ACTD to TERMINAL 3 of the door lock motors to TERMINAL 2 to
TERMINAL ACT+ of the body ECU to TERMINAL GND to GROUND and the door lock motor causes all the doors to unlock.
