STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Turn the ignition switch to the ON position. • Operate the power window switch in automatic mode. • Does the door glass move up and down in automatic mode? | Yes | Go to the next step.

No

• Door glass does not move up and down in automatic mode:

  - Go to Step 1 of NO. 1 DOOR GLASS DOES NOT MOVE UP AND DOWN IN AUTOMATIC MODE.

• Door glass moves up and down in automatic mode, but door glass reverses:

  - Go to Step 1 of NO. 3 DOOR GLASS REVERSES EVEN THOUGH THE GLASS DOES NOT ENCOUNTER A FOREIGN OBJECT WHILE IT IS MOVING UP IN AUTOMATIC MODE.

2 | • Gently pull the power window switch while the door glass is moving down in automatic mode. • Does the glass stop? | Yes | Go to the next step.
No | Replace the power window switch, then go to the automatic door glass return function inspection.
3 | • Gently press the power window switch while the door glass is moving up in automatic mode. • Does the glass stop? | Yes | • Automatic mode function is normal. • Go to the automatic door glass return function inspection.
No | Replace the power window switch, then go to the automatic door glass return function inspection.

## Automatic Door Glass Return Function Inspection

  Note

  • Perform the following inspection for the power window main switch and the power window subswitches for each window.
  • With the switch held at auto-up, the door glass does not automatically reverse even when a foreign object is encountered.

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Turn the ignition switch to the ON position. • Lower the door glass completely. • Use the power window switch to close the door glass in automatic mode. • Does the door glass automatically reverse even though the glass does not encounter a foreign object while it is moving up in automatic mode? | Yes | Go to Step 1 of NO. 3 DOOR GLASS REVERSES EVEN THOUGH THE GLASS DOES NOT ENCOUNTER A FOREIGN OBJECT WHILE IT IS MOVING UP IN AUTOMATIC MODE.
No | Go to the next step.
2 | • Lower the door glass completely. • Take a hammer and hold it against the inside of the top of the window frame so that the door glass will hit its handle when it is closed. • Raise the door glass using automatic mode. • When the door glass hits the hammer handle, does it immediately reverse and move down to approx. 200 mm {7.87 in} from the completely closed position? | Yes | • Automatic door glass return function inspection is normal. • Go to the IG OFF timer function inspection.
No | Go to Step 1 of NO. 2 DOOR GLASS DOES NOT REVERSE, EVEN WHEN ENCOUNTERING A FOREIGN OBJECT IN ITS PATH.

## IG OFF Timer Function Inspection

STEP | INSPECTION | ACTION
--- | --- | ---

1

• Close all doors.
• Turn the ignition switch to the ON position.
• In automatic mode, push down the power window main switch for the driver-side front door glass. The door glass should move down within approx. 42 s after ignition switch off.
• In manual mode (finger continuously depressing the power window main switch), the door glass should move down within approx. 42 s after ignition switch off.
• Does the driver-side front door glass move down?

Yes

Go to the next step.

No

• Perform the driver-side power window system initial setting procedure, and reinspect.(See POWER WINDOW SYSTEM INITIAL SETTING.)
• If it does not move up and down upon reinspection, inspect the following:

  - Wiring harness for the door open/close signal system
  - Latch switch

• Repair or replace the malfunctioning part, and reinspect.

  - If operation is not normal, replace the power window main switch, and then go to the next step.

2

• Turn the ignition switch to the ON position.
• In automatic mode, pull up the power window main switch for the driver-side front door glass. The door glass does not move up within approx. 42 s after ignition switch off.
• Verify that driver-side front door glass does not operate.
• Does the driver-side front door glass move up?

Yes

• Perform the driver-side power window system initial setting procedure, and reinspect.(See POWER WINDOW SYSTEM INITIAL SETTING.)

  - If operation is not normal, replace the power window main switch, then go to the next step.

No | Go to the next step.

3

• Turn the ignition switch to the ON position.
• Lower the driver-side front door glass completely.
• Take a hammer and hold it against the inside of the top of the door glass frame so that the door glass will hit its handle when it is closing.
• Raise the door glass using manual mode.
• When the door glass hits the hammer handle, does it immediately reverse and move down to approx. 200 mm {7.87 in} from the completely closed position?

Yes

Go to the next step.

No

• Perform the driver-side power window system initial setting procedure, and reinspect.(See POWER WINDOW SYSTEM INITIAL SETTING.)

  - If operation is not normal, replace the power window main switch, then go to the next step.

4 | • Open any door. • Turn the ignition switch to the ON position. • Push/pull the power window main switch for the door glass within approx. 42 s after ignition switch off. • Verify that the door glass does not move up or down. • Does the door glass move up or down? | Yes | • Inspect the door switch and related wiring harness. • If above parts are normal, replace the power window main switch, then go to the next step. • If the above parts have any malfunction, repair or replace the malfunction part, then go to the next step.
No | Go to the next step.

5

• Close all doors.
• Turn the ignition switch to the ON position.
• Push/pull the power window main switch for door glass after approx. 60 s after ignition switch off.
• Verify that the door glass does not move up or down.
• Does the door glass move up or down?

Yes

• Perform the driver-side power window system initial setting procedure, and reinspect.(See POWER WINDOW SYSTEM INITIAL SETTING.)

  - If operation is not normal, replace the power window main switch, then go to the two-step down function inspection.

No | • The IG OFF timer function is normal. • Go to the two-step down function inspection.

## Two-step Down Function Inspection

• The distance the door glass opens can be changed using the two-step down function (approx. 20-100 mm {0.79-3.93 in}).

• The two-step down function can be made inoperative. (The function is operative at the initial setting.)

• The two-step down function does not function during IG OFF timer.

  Note

  • Perform the following inspection for the power window main switch and the power window subswitches for each window.

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Turn the ignition switch to the ON position. • Raise door glass completely. • When the door glass is lowered using manual mode, does it move down to approx. 30 mm {1.2 in} from the completely closed position and stop for 1 s? (This inspection cannot be performed during IG OFF timer function operation.) | Yes | • Two-step down function is normal. • Reinspect malfunction symptoms.

No

• Perform the power window initial setting procedure and verify auto-up/down operation.(See POWER WINDOW SYSTEM INITIAL SETTING.)

  - If the automatic function does not operate, go to Automatic Door Glass Return Function Inspection.
  - If the automatic function operates but the two-step down function does not, replace the power window switch.
