When the home position is set before the vehicle is handed over, the window glass position and direction of operation are stored in the control module in the power window master switch. Thus, home position adjustment is necessary if the cable is disconnected from the negative battery terminal, the main switch connector or the power window motor connector.
Note. If the home position has not been set, the functions of the automatic operation of the driver's side power window system, automatic window return and fine movement will not be available.
