SYSTEM INITIALIZATION

Description

INFOID:0000000009757228

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 replaced.

• Electric power supply to power window main switch or power window motor (driver 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 harness connector.

• Removal of power window motor (driver side) from regulator assembly.

• Operation of regulator assembly as an independent unit.

• Removal and installation of glass.

• 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

Work Procedure

INFOID:0000000009757229

1.

STEP 1

1. Turn ignition switch ON.

2. Operate power window switch to fully open the window. (This operation is unnecessary if the window is

already fully open)

3. Operate the power window switch in the UP position (AUTO-UP operation). Even after glass stops at fully

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

4. Release the switch and check that AUTO-UP function operates normally.

>> GO TO 2.

2.

STEP 2

Check anti-pinch function. Refer to 

PWC-30, "Work Procedure"

.

ANTI-PINCH INSPECTION

ANTI-PINCH INSPECTION

Description

INFOID:0000000009757230

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 replaced.

• Electric power supply to power window main switch or power window motor (driver 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 harness connector.

• Removal of power window motor (driver 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:0000000009757231

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 (5.91 in.) without pinching piece of wood and stops.

-

Check that glass does not rise not when operating the power window main switch 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.
