B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

POWER WINDOW
Communication between power window master SW and body ECU is controlled and body ECU recognizes the conditions of
each SW to control the operation of windows.
1. MANUAL UP OR DOWN OPERATION (DRIVER'S WINDOW, PASSENGER'S WINDOW)
During you are pushing power window master SW (Driver side) halfway down, the motor operates and the window on the
driver's side opens. During you are pulling power window master SW (Driver side) halfway up, the motor operates and the
windows on the driver's side closes. The window on the passenger's side opens or closes by pushing down or pulling up
power window master SW (Front passenger, rear passenger) or power window SW front RH, rear LH, RH.
2. AUTO UP OR DOWN OPERATION (DRIVER'S WINDOW)
When the power window master SW (Driver side) is fully pushed down, the motor operates and the window on the driver's
side automatically opens. When the power window master SW (Driver side) is fully pulled up, the motor operates and the
window on the driver's side automatically closes.
3. STOPPING AUTOMATIC WINDOW OPERATION
If you push the power window master SW (Driver side) halfway down during the window on the driver's side is raising
automatically, the motor's operation stops. And if you pull the power window master SW (Driver side) halfway up during the
window on the driver's side is lowering automatically, the motor's operation stops.
4. KEY OFF POWER WINDOW OPERATION
After the Ignition SW is turned off, the windows can be operated for about 43 seconds. However, the window operation stops
when either front doors opens.
5. JAM PROTECTION FUNCTION (DRIVER'S WINDOW)
When any foreign object gets caught during power window UP operation, the motor rotates in the opposite direction to open
the window.

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.
*Unlock operation from the driver's side door
When the driver's side door is unlocked once using the ignition key, only the driver's side door is unlocked. If this operation
is repeated within 3 seconds, all the other doors are unlocked.
*Lock operation from the front passenger's side door
When the front passenger's side door is locked using the ignition key, all the doors are locked.
*Unlock operation from the front passenger's side door
When the front passenger's side door is unlocked using the ignition key, all the doors are unlocked

WIRELESS DOOR LOCK CONTROL
The current is always sent from DOOR fuse to TERMINAL B of body ECU. At the same time, the current is always sent from
DOME fuse to TERMINAL CPUB of power window master SW, and from ECU±B fuse to wireless door lock receiver. When
ignition SW is turned on, the current is sent from GAUGE fuse to TERMINAL IG of body ECU.
1. WIRELESS DOOR LOCK OR UNLOCK NORMAL OPERATION
*Lock operation
When the LOCK SW of the transmitter is pushed, all the doors are locked.
*Unlock operation
When the UNLOCK SW of the transmitter is pushed, all the doors are unlocked.
2. AUTOMATIC LOCK OPERATION
After all the doors are unlocked by pushing the UNLOCK SW of the transmitter, unless each of the doors is opened or the
ignition key is inserted, all the doors are locked again.
3. VISUAL CONFIRMATION OF LOCK OR UNLOCK FUNCTION
When doors are locked by using the transmitter, the taillight and parking lights blink once. When doors are unlocked by using
the transmitter, the taillights and parking lights blink twice. If UNLOCK SW of the transmitter is pushed while all the doors are
locked, doors are unlocked and the room lights are turned on simultaneously.
4. WIRELESS CONTROL STOP FUNCTION
If the following situations occur, wireless door lock function does not operate.
*When each of the doors opens. (Door courtesy SW is on)
*When ignition key is inserted to ignition SW. (Unlock warning SW is on)
*When ignition SW is on.
5. REPEAT FUNCTION
If the doors are not locked after the lock signal is out put from transmitter by pushing LOCK SW, the lock signal is sent again
to lock the doors.
6. PANIC MODE FUNCTION
When the panic SW of the transmitter is pushed, the horn comes on, and the headlight and taillight flashes.
