Initialization After installing each component to the vehicle, follow the steps below.
1. Disconnect the battery negative c able 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 procedure if the
window is already fully opened).
4. Move the power window switch in the up direction (auto close position) and hold. Keep holding the switch
even when window is completely closed, and then release after 4 seconds have passed.
5. Inspection of the ant i-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.) near the fully closed position.
3. Carry out fully closing operation with auto up switch.
• Check that the glass reverses without pinching the w ooden 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 while it is reversing or lowering.
CAUTION:
• Use care to avoid being pinched du ring the inspection. Do not use a hand, etc. in place of the
wooden piece durin g the inspection.
• 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 bolts, guide rail
bolts, and the glass and guide rail bolts to correct the glass position.
• Make sure the system is normal with raising and lowering the glass.
