Check the regulator assembly for the following items. Replace or
grease it if a malfunction is detected.
• Wire wear
• Regulator deformation
The arrows in the figure show the application points of the multi-pur-
pose grease.

SYSTEM INITIALIZATION

Initialize the system if any of the following work has been done.
• Electric power supply to power window switch or motor is interrupted by blown fuse or disconnecting battery

cable, etc.

• Removal and installation of the regulator assembly.
• Removal and installation of the motor from the regulator assembly.
• Removal and installation of the harness connector of the power window switch.
• Operation of the regulator assembly as a unit.
• Removal and installation of the door glass.
• Removal and installation of the body side weatherstrip and door weatherstrip.
• Disconnection and connection of the minus terminal of battery.

Initialization

Follow the steps below after installing each component to the vehicle.
1.

Disconnect the minus terminal of battery or disconnect power window switch harness connector tempo-
rarily. Then reconnect after at least 1 minute.

2.

Close the door.

3.

Turn ignition switch ON.

4.

Operate power window switch to make over a half of the window open area.

5.

Draw fully the power window switch in the up direction (auto close position) and hold. Continue holding
the switch even when window is completely closed and then release after 3 seconds.

6.

Inspect the anti-pinch system function.
NOTE:
Initialization may be cancelled with continuous opening and closing operation. In this case, initialize the
system.

INSPECT THE FUNCTION OF THE ANTI-PINCH SYSTEM

1.

Fully open the door glass.

2.

Place a wooden piece (wooden hammer handle, etc.) at near fully closed position.

3.

Perform fully closing operation with auto up switch.

• Check that the glass reverses without pinching the wooden piece, is lowered approximately 150 mm (5.91

in) or for 2 seconds and then stops.

• The glass should not be raised with power window main switch operated while it is reversing or lowering.

CAUTION:

• Be careful not to be pinched.
• Check that the auto up function is normal before the inspection following the system initialization.

FITTING INSPECTION

• Check that the glass is fit securely into the sash groove.
• Lower slightly the glass [approximately 10 to 20 mm (0.39 to 0.79 in)] and check that the clearance to the

body side weatherstrip is parallel. Loosen the regulator mounting bolts, guide rail mounting bolts, and glass
and guide rail mounting bolts to correct the glass position if the clearance between the glass and body side
weatherstrip is not parallel.
