Power Window Safety Switch: Description and Operation
ANTI-TRAP
The anti-trap function is enabled for the drivers window closing in both the inching and one-shot modes. If the anti-trap feature is activated while a window is closing, the window motor is reversed for 0.5 second.
A Hall sensor, located in the drivers window regulator, monitors the speed of the motor and if the speed decreases below a set threshold, indicating an obstruction, the power feed to the motor is reversed so the window goes back down.
In an emergency the anti-trap function can be overridden by holding the window switch in the one-shot closed position.
After the battery has been disconnected it is necessary to initialize the drivers door window motor to be able to operate the one-shot up function.
Driver's Door Window Motor Initialisation
^ Operate the drivers window switch until the window glass is in the fully closed position, continue to operate the window switch for a further two seconds
^ Release the window control switch.
^ Operate the drivers window switch in the closed position and continue to operate the window switch for a further two seconds.
^ Operate the drivers window switch until the window is in the fully open position (one-shot down).
NOTE: If the drivers window motor initialisation has been completed correctly, when the drivers window switch is operated, the window should move to the fully closed position (one-shot up) automatically. If the window does not fully close automatically (one-shot up), repeat the complete procedure.
^ Operate the drivers window switch once to the close position.
