Description

INFOID:0000000009176195

If any of the following operations are performed, the initialization is necessary for normal operation of power

window system.

• When control unit replaced.

• Electric power supply to power window switch or motor is interrupted by blown fuse or disconnection and

connection of the negative battery terminal.

• Removal and installation of regulator assembly.

• 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 door glass.

• Removal and installation of door glass run.

The following specified operations can not be performed under the non-initialized condition.

• Anti-pinch function

Work Procedure

INFOID:0000000009176196

1.

STEP 1

1. Disconnect battery negative terminal or power main switch connector. Reconnect it after a minute or

more. 

2. Turn ignition switch ON.

3. Operate the power window switch to fully open the window. (This operation is not necessary if the window

is already fully open).

4. Continue pulling the power window switch UP (AUTO-UP operation). Even after the glass stops at fully

closed position, keep pulling the switch for 4 seconds or more. 

5. Retest the AUTO-UP function operation.

• Removal and installation of regulator assembly.

• 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 door 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

Work Procedure

INFOID:0000000009176198

1.

CHECK ANTI-PINCH FUNCTION

• Fully open the door window.

• Place a piece of wood near fully closed position.

• Close door glass completely with AUTO-UP.

• 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 normally.

• 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.
