DRIVER SIDE POWER WINDOW SYSTEM OUTLINE

id091200684200

• On the basis of the pulse signals from the Hall effect switches in the power window motor, the power window control module in the power window main switch determines the window position and the operation direction. Accordingly, the power window main switch controls the driver-side power window system.
• When the initial position is set before vehicle delivery, the window position and the operation direction are stored in the power window control module in the power window main switch. Thus resetting the initial position is necessary if the battery negative cable, power window main switch connector, or power window motor connector is disconnected.
Note
• If the initial position has not been set, the driver-side power window system's auto function, the auto window return function and the precise motion function will not function.
• See the workshop manual for more information about setting the initial position. (Mazda6 Workshop Manual 3365-1*-02G)
