SYSTEM INITIALIZATION
If any of the following work has been done, initialize the system.

Electric power supply to power window switch or motor is interrupted by blown fuse or disconnecting bat-
tery 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.

Operate the regulator assembly as a unit.

Removal and installation of the door glass.

Removal and installation of the door glass run.
Initialization
After installing each component to the vehicle, follow the steps below.
1. Disconnect the minus terminal of battery or disconnect power window switch's harness connector tempo-
rarily, then reconnect after at least 1 minute.
2. Turn ignition switch ON.
3. Open the window to its full width by operating the power window switch. (Exclude this pocedure if the win-
dow is already fully opened)
4. Fully draw the power window switch in up direction (auto close position) and hold, keep holding the switch
even when window is completely closed and then release afeter 3 second has passed.
5. Inspection of 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. Carry out fully closing operation with auto up switch.

Check that the glass reverses without pinching the wooden piece, is lowered approx.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.

Check that the glass reverses without pinching the wooden piece, is lowered approx.150mm (5.91in) 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:

Do not inspect with pinching a part of worker's body, a hand etc. Work carefully not to be pinched.

Check that auto up function is normal before inspection following the system initialization.
FITTING INSPECTION

Make sure the glass is securely fit into the glass run groove.

Lower the glass slightly [approx. 10 to 20 mm (0.39 to 0.79 in)], and make sure the clearance to the sash
is parallel. If the clearance between the glass and sash is not parallel, loosen the regulator mounting bolts,
guide rail mounting bolts, and glass and carrier plate mounting bolts to correct the glass position.
