奔驰轿车座椅按摩功能不能使用

来源:http://www.jnrunao.com/ 日期:2021-05-06 发布人:runao
故障现象:
Fault phenomenon:
一辆行驶里程约17.2万km的奔驰S600轿车。客户反映:该车座椅的按 摩功能不能用。
A Benz S600 with a mileage of about 172000 km. The customer said: the massage function of the car seat is not available.
故障诊断:
Fault diagnosis:
接到车辆后,根据客户的描述进行车辆检查,欣车汇技师查看发现多仿形座椅功能失效,座椅的按 摩功能不能用,确认客户反映的故障。然后技师将座椅的按摩级数调至任何数值,数值会自动跳至。位置,座椅的按 摩功能无法启用。技师深入检查发现,整个多仿形座椅系统功能失效,主驾驶座椅、副驾驶座椅以及后排乘客座椅都无法使用该按 摩功能。
After receiving the vehicle, the vehicle was checked according to the customer's description. Xinchehui technician found that the function of multi profiling seat was invalid, and the massage function of the seat was not available. The fault reflected by the customer was confirmed. Then the technician will adjust the massage level of the seat to any value, and the value will automatically jump to. Position, seat massage function cannot be activated. Technicians in-depth inspection found that the entire multi profiling seat system function failure, the main driver's seat, CO driver's seat and rear passenger's seat can not use the massage function.
故障分析排查:
Troubleshooting:
用奔驰诊断仪进入控制单元对压缩机进行促动,工作正常,说明压缩机的供电搭铁正常。
Use Benz diagnostic instrument to enter the control unit to actuate the compressor, which works normally, indicating that the power supply and grounding of the compressor are normal.
诊断仪查看压力传感器实际值,发现压力达到200kPa之后,压力不能保持住,会慢慢下降,说明管路有泄漏的地方。
The diagnostic instrument checks the actual value of the pressure sensor, and finds that the pressure can not be maintained after the pressure reaches 200KPa, and it will slowly drop, indicating that there is leakage in the pipeline.
手动打气泵,对管路进行打 压,从空气压缩机旁边的分配阀到前排座椅管路分别加压,压力不变,保压正常。
The manual air pump pressurizes the pipeline, pressurizes the pipeline from the distribution valve beside the air compressor to the front seat, the pressure remains unchanged, and the pressure is maintained normally.
对储气罐进行密封加压,保压也正常。
Seal and pressurize the air tank, and the pressure is normal.
给系统打 压后仔细在后备箱观察多仿形座椅泵周围,听到有轻微的漏气声音。于是对后备箱内管路进行检查,发现在压缩机上有个分配阀。
After pressurizing the system, carefully observe around the multi profiling seat pump in the trunk and hear a slight air leakage sound. So the trunk of the pipeline inspection, found that there is a distribution valve on the compressor.
对分配阀进行加压,发现压力慢慢下降,仔细观察分配阀,并未发现有异常现象。但靠近气泵分配阀时,感到有气体吹出,能感觉到有轻微的漏气。多仿形座椅气泵出现轻微的泄漏。
After pressurizing the distribution valve, it was found that the pressure decreased slowly. After careful observation of the distribution valve, no abnormal phenomenon was found. But close to the air pump distribution valve, I feel that there is gas blowing out, and I can feel that there is a slight air leakage. Slight leakage of multi profiling seat air pump.
对打气泵分配阀进行涂抹胶水修 复。等胶干后再次对分配阀加压测试,还是泄压。再次仔细检查,发现压力传感器旁边也有泄压地方,接着进行再次涂抹胶水修 复,再次加压,没有了泄压现象。然后对动态座椅系统执行按 摩功能测试,功能一切正常。
Apply glue to the distribution valve of air pump for repair. When the glue is dry, pressurize and test the distribution valve again, or relieve the pressure. After careful inspection again, it was found that there was a pressure relief place beside the pressure sensor, and then it was repaired by applying glue again. After pressurization again, there was no pressure relief phenomenon. Then the massage function test is performed on the dynamic seat system, and all functions are normal.
解决方案:
Solution:
更换 新的行驶动态座椅调节气动泵,反复测试后没有再出现过以前的故障现象,故障排除。
Replace the driving dynamic seat adjustment pneumatic pump with a new one. After repeated tests, the previous fault phenomenon does not appear again. Troubleshooting.
