When the negative terminal of battery is disconnected, the initialization is necessary.
If any of the following operations are performed, the initialization is necessary as well as when the negative
terminal of battery is disconnected.
 Power supply to the power window main switch or power window motor is cut off by the removal
of battery terminal or if the battery fuse is blown.
 Disconnection and connection of power window main switch harness connector.
 Removal and installation of motor from regulator assembly.
 Operation of regulator assembly as an independent unit.
 Removal and installation of glass.
 Removal and installation of door glass run.
The following specified operations can not be performed under the non-initialized condition.
 Auto-up operation
 Anti-pinch function

INFOID:0000000003825990
INITIALIZATION PROCEDURE
1. Disconnect battery negative terminal or power window main switch connector. Reconnect it after a minute
or more.
2. Turn ignition switch ON.
3. Operate power window switch to fully open the window. (This operation is unnecessary if the window is
already fully open)
4. Continue pulling the power window switch UP (AUTO-UP operation). Even after glass stops at the fully
closed position, keep pulling the switch for 2 seconds or more.
5. Initializing procedure is completed.
6. Inspect anti-pinch function.
CHECK ANTI-PINCH FUNCTION
1. Fully open the door window.
2. Place a piece of wood near fully closed position.
3. Close door glass completely with AUTO-UP.
 Check that glass lowers for approximately 150 mm (5.9 in) or for 2 seconds without pinching piece of wood
and stops.
 Check that glass does not rise when operating the power window main switch while lowering.
CAUTION:
• Perform initial setting when auto-up operation or anti-pinch function does not operate normally.
 Check that AUTO-UP operates before inspection when system initialization is performed.
 Never check with hands or other body parts because they may be pinched. Never get pinched.
 It may switch to fail-safe mode if open/close operation is performed continuously without fully clos-
ing. Perform initial setting in that situation. Refer to PWC-72, "
Fail-safe"
 Finish initial setting. Otherwise, next operation cannot be done.
1. Auto-up operation
2. Anti-pinch function

When the control unit is replaced, the initialization is necessary.
If any of the following operations are performed, the initialization is necessary as well as when the control unit
is disconnected.
 Power supply to the power window main switch or power window motor is cut off by the removal
of battery terminal or if the battery fuse is blown.

POWER WINDOW SYSTEM
System DiagramINFOID:0000000003825993
System DescriptionINFOID:0000000003825994
POWER WINDOW OPERATION
 Power window main switch (driver side) can open/close all windows.
 Front & rear power window switch can open/close the corresponding windows.
 Power window system is operable while the retained power operation timer is active after turning ignition
switch ON and OFF.
POWER WINDOW AUTO-OPERATION (DRIVER SIDE)
 AUTO UP/DOWN operation can be performed when power window main switch is turned to AUTO.
 Encoder continues detecting the movement of power window motor and transmits the encoder pulse signal
to power window main switch while power window motor is operating.
 Power window main switch reads the changes of encoder signal and stops AUTO operation when door glass
is at the fully opened/closed position.
 Auto function is inoperable if encoder is malfunctioning.
RETAINED POWER OPERATION
Retained power operation is an additional power supply function that enables power window system to oper-
ate for 45 seconds even when ignition switch is turned OFF.
RETAINED POWER FUNCTION CANCEL CONDITIONS
 Front door CLOSE (door switch OFF) → OPEN (door switch ON).
 When ignition switch is ON again.
 When timer time passes. (45 seconds)
POWER WINDOW LOCK
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits
power window switch operation except with the power window main switch.

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
