1、Service DepartmentService.193Convenience SystemConstruction and OperationSelf-Study ProgrammeThe customer gauges the level of comfort of a vehicle not only by its handling and the level of comfort afforded by the passenger cabin.The ease of operation of the various components, such as central lockin

2、g, mirror adjustment, electric windows or interior light, are also major factors in the customers appraisal of a vehicle.We therefore collectively refer to these functions as the “Convenience System”.The rapid development of microelectronicsand micromechanics hasit possible tooptimise and simplify t

5、bout the convenience systemThe first generation of the convenience system was featured on the Passat 97.Door control unitsAs of myear 1998 the Golf and Passat willbe equipped with the second generation ofconvenience system. The distinguishing fea- tures of the new system are the two-touch switches i

6、n the door control panel on the drivers side.The sub-functions of the convenience system, such as central locking, mirror adjustment and-theft warning system, have basically remained unchanged.However, the design and the layout of the convenience system are new.Compared with the previous system, the

7、 new system now has a decentralised layout. This means that the tasks of the convenience system are shared by several control units.193_081Door control unitsCentral control unitl Advantage of the decentralised system:if a fault occurs in one control unit, only a small part of the overall system fail

8、s.Central control unitThe convenience system is installed in combination with electric windows.The functions of the convenience system are controlled by a central control unit and also by two or four door control units.Door control unit,drivers sideDoor control unit, front passenger side193_029Two v

16、sSleep modeWake-updTo reduce no-load power consumption, the control units go into a sleep mode. This occurs when the ignition is switched off and the doors are locked or when the function hold period (e.g. electric windows) has elapsed.When a control unit detects a wake-upd which is initiated by an

17、action such as opening the vehicle, it transfersthe wake-upd to the othercontrol units via the CAN databus so that they, too, are activated.d: wake-upIgnition OffIgnition Off andwindow function hold period expired7Wait150 mANormal operation 150 mASleep mode6 mAIn sleep mode, the- theft warning syste

26、stem control units are interconnected by two lines, known as the CAN databus.Switching signals, lock states and additional information are transmitted via the CANbus.Advantage of the databuswithout databusThe data interchange procedure is as follows:193_104If the databus is not installed, a large nu

31、unit is located below the floor covering in front of the drivers seat.On the Golf 98 you will find the central control unit in the dash panel insert.If the central control unit fails, the convenience system goes into emergency mode.The functions of the central control unit are disabled.In this case,

32、 functions which require information from the central control unit can only be executed partially, if at all.When you renew a central control unit, the new control unit must be encoded.13The door control unitsThe door control units monitor and control the convenience system functions shown in the di
