  讲解一下奔驰C230中控门锁工作不良的原因:奔驰C230
  Explain the reasons for poor control of the Mercedes Benz C230 lock:
  故障现象:一辆奔驰C230双门掀背轿跑车进厂维修,车主描述为该车中控门锁在远距离时不起作用,只有把钥匙对着门把手时才能进行锁门或开门的控制,同时收音机搜索不到任何频道。
  Fault phenomenon: a Mercedes C230 coupe hatchback coupe into the factory maintenance, owners describe for the car door lock control does not work in the distance, only to control to open or lock the door key to the door handle, and not search any radio channel.
  故障诊断:根据车主描述的故障现象分析.应该是车辆上安装的无线电接收装置有问题.在该款车型上装备的奔驰DAS3防盗系统,在车辆解锁过程中是通过无线电和红外线两个路径控制的,查询奔驰资料WlS,确认无线电接收装置的大概位置。打开后备箱盖.拆掉内饰板。将2、4拆掉后就可以看到天线放大器模块.在拆出后发现,有非常严重的腐蚀痕迹。询问车主后得知.一个月前,该车在某汽车装潢店贴过车膜,贴膜是打开后备箱盖,呈半直立状态时从内部贴上去的.为了减少气泡并容易处理.多数情况下工作人员会在贴膜时使用少量的水.正是这些残留的水流到了安装天线放大器的缝隙里。打开天线放大器的外壳,内部已经严重腐蚀.用清洁剂清洗干净后安装好再试验,没有任何变化,天线放大器已经彻底损坏.只能更换一个新的。
  Fault diagnosis: according to the analysis of fault phenomenon owners describe. Should be installed in the vehicle radio reception device. Benz DAS3 anti-theft system equipment in the car on the vehicle in the unlocking process through the radio and infrared two path control, Benz WlS query data, confirm the approximate location of the radio receiving device. Open the trunk lid trim down. 2, 4 will be removed after you can see the antenna amplifier module. Found in the demolition, there are traces of corrosion is very serious. Asked the owner after that. A month ago, the car had posted a car in a car decoration shop, the film is to open the trunk lid, a semi erect state posted up from within. In order to reduce air bubbles and easy to handle. The staff in most cases will use a small amount of water in the film. It is these residues the water flow to the slot antenna amplifier in installation. Open the housing of the antenna amplifier, the interior has been severely corroded. After cleaning with a cleaning agent to install the test again, without any changes, the antenna amplifier has been completely damaged.
  更换上新的天线放大器,检查工作状况,效果有所改善.但是遥控距离只有五六米,超过五六米的时候.还是不能遥控开锁.收音机也是稍有好转.检查实际值.基本正常,没有故障存储.检查接头时发现在新的天线放大器上有几块胶布粘在接收点上.怀疑可能是他影响了无线电的接收效果(常规来说无线电的接收应该不受其影响)。将胶布撕掉按照正确的位置安装好后再试,正常.收音机搜索频道也没问题。
  The replacement of the new antenna amplifier, check the working condition, the effect is improved. But the remote distance is only five or six meters, when more than five or six meters. Still can not unlock. Remote radio is also slightly improved. Check the actual value. The basic normal, no fault stored. When the joint inspection is now the new antenna amplifier have a few pieces of cloth stick at the receiving point. Suspected he influenced the reception radio (conventional radio receiver should not be affected). The tear tape in the correct position after installation of the normal radio channel search. Try again, no problem.
