Car Access System 4

The Car Access System 4 is the central control unit for opening and closing the windows. Therefore, it issues the enable to operate the power windows.

"Terminal 50 ON" status is sent while starting the engine. The junction box electronics and the footwell module prevent operation of the power windows during the start procedure or interrupt current operation of the power windows. This means more energy from the battery is available for the starter during engine start-up.
