SYSTEM INITIALIZATION

SYSTEM INITIALIZATION

Description

INFOID:0000000007563136

If any of the following operations are performed, the initialization is necessary for normal operation of power
window system.
• Disconnection and connection of battery cable from negative terminal.
• When power window main switch or front power window switch (passenger side) replaced.
• Electric power supply to power window main switch or front power window switch (passenger side) or power

window motor (driver side/passenger side) is interrupted by blown fuse or disconnection and connection of
the negative terminal of battery, etc.

• Disconnection and connection of power window main switch or front power window switch (passenger side)

harness connector.

• Removal of power window motor (driver side/passenger side) from module assembly.
• Operation of module assembly as an independent unit.
• Removal of regulator assembly from module assembly.
• Removal and installation of glass.
• Removal and installation of weather-strip.
• Removal and installation of door glass run.

CAUTION:

The following specified operations can not be performed under the non-initialized condition.
• Auto-up operation
• Anti-pinch function
• Automatic window adjusting function

Work Procedure

INFOID:0000000007563137

1.

STEP 1

1.

Turn ignition switch ON.

2.

Close roof.

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 fully closed
position, keep pulling the switch for 2 seconds or more.

5.

Check that AUTO-UP function operates normally.

>> GO TO 2.

2.

STEP 2

Check anti-pinch function. Refer to

PWC-27, "Work Procedure"

.

CHECK ANTI-PINCH FUNCTION

Description

INFOID:0000000007563138

If any of the following operations are performed, the initialization is necessary for normal operation of anti-
pinch function.
• Disconnection and connection of battery cable from negative terminal.
• When power window main switch or front power window switch (passenger side) replaced.
• Electric power supply to power window main switch or front power window switch (passenger side) or power

window motor (driver side/passenger side) is interrupted by blown fuse or disconnection and connection of
the negative terminal of battery, etc.

• Disconnection and connection of power window main switch or front power window switch (passenger side)

harness connector.

• Removal of power window motor (driver side/passenger side) from regulator assembly.
• Operation of regulator assembly as an independent unit.
• Removal and installation of glass.
• Removal and installation of door glass run.

Work Procedure

INFOID:0000000007563139

1.

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.

4.

Check the following conditions.

-

Check that glass lowers for approximately 150 mm (5.9 in) without pinching piece of wood and stops.

-

Check that glass does not rise not when operating the power window main switch or front power window
switch (passenger side) while lowering.

CAUTION:

•

Perform initial setting when AUTO-UP operation or anti-pinch function does not operate nor-
mally.

•

Check that AUTO-UP operates before inspection when system initialization is performed.

•

Do not check with hands and other body parts because they may be pinched. Do not get
pinched.
