DOOR LOCK CONTROL
The current is always sent from DOOR fuse to TERMINAL B of body ECU. When ignition SW is turned on, the current is sent
from GAUGE fuse to TERMINAL IG of the body ECU.
1. MANUAL LOCK OPERATION
When the door lock control SW (Power window master SW) is turned to LOCK position, the lock signal from TERMINAL
MPX1 of power window master SW is input to TERMINAL RX of body ECU to operate ECU. The current is sent from
TERMINAL ACT+ of ECU to each motor and the motor locks the doors by the current sent from TERMINAL ACT± of ECU to
GROUND.
2. MANUAL UNLOCK OPERATION
When the door lock control SW (Power window master SW) is turned to UNLOCK position, the unlock signal from
TERMINAL MPX1 of power window master SW is input to TERMINAL RX of body ECU to operate ECU. The current is sent
from TERMINAL ACT± of ECU to each motor and the motor unlocks the doors by the current sent from TERMINAL ACT+ of
ECU to GROUND.
3. DOOR KEY LOCK AND UNLOCK OPERATION
*Lock operation from the driver's side door
When the driver's side door is locked using the ignition key, all the doors are locked.

Because weak electric wave is used, when
there is strong wave or noise in the used
frequency ,operation distance might be
shortened.
NoYe s
Only wireless function (Remote control) will not operate.
(If a new transmitter or a transmitter of the same type that works properly with the vehicle is not available.)
