汽车故障检测仪

Automobile fault detector

所谓汽车故障诊断是指在一定工作环境下查明导致系统某种功能失调的原因或性质，判断劣化状态发生的部位或零部件，以及预测状态劣化的发展趋势等，包括故障检测，故障定位和故障预测。如汽车解码器是汽车故障检测仪的一种。

The so-called automobile fault diagnosis means to find out the causes or properties that lead to some functional maladjustment in a certain working environment, determine the parts or parts of the deterioration state, and the trend of the deterioration of the predicted state, including fault detection, fault location and fault prediction. For example, the automobile decoder is a kind of automobile fault detector.

用途

purpose

用于检测汽车故障的便携式智能汽车故障自检仪 ，用户可以利用它迅速地读取汽车电控系统中的故障，并通过 128*64 的液晶显示屏显示故障信息，迅速查明发生故障的部位及原因。避免了传统的汽车故障自检仪需要查阅说明书中的故障码表的麻烦。包括重型卡车、轻型卡车、客车、工程机械都可以直接进行汽车故障检测。

The portable intelligent vehicle fault self inspection instrument used to detect automobile failures can be used to quickly read the faults in the electronic control system of the automobile and to display the fault information through the 128*64 LCD screen, and quickly find out the parts and causes of the failure. It avoids the trouble of the traditional auto fault self checking instrument needing to consult the fault code table in the instruction manual. Including heavy trucks, light trucks, buses and construction machinery can directly detect vehicle faults.

工作原理

Working principle

手动读取故障码和清除故障码，外型小巧便于携带，操作简单，性价比高。适合车主或司机使用，专车专用，准确无误。 使用者把本设备与汽车电脑诊断座相连，即可通过手动操作上面的按键来读取或清除汽车电控系统中的故障。汽车故障检测仪还可使保养灯归零。Automobile doctor For OBD-II可以[读取数据流]，读取对汽车产生重要影响的运行参数，包括：发动机转速、汽车车速、冷却液温度、进气温度、节气门开度、电瓶电压、点火角、氧传感器电压等。并且可以获得参数的详细情况，通过将该参数的实际数值与参考值比较可以判断该参数是否异常。

Manually read fault codes and erase fault codes. They are compact and portable, easy to operate, and cost-effective. Suitable for owners or drivers to use, special purpose vehicle, accurate. The user connects the device to the computer diagnostic stand and can read or remove the faults in the electric control system by manually operating the buttons above. The car fault detector can also make the maintenance light zero. Automobile doctor For OBD-II can [read the data stream] to read the operating parameters that have an important impact on the car, including engine speed, car speed, coolant temperature, intake temperature, throttle opening, battery voltage, ignition angle, oxygen sensor voltage and so on. And the details of the parameters can be obtained. By comparing the actual value of the parameter with the reference value, it is possible to determine whether the parameter is abnormal.

操作方法

Operation method

汽车故障检测仪要看对应什么车系，不同的车系对应不同的插头，目前市面多为OBD2和OBD2带CAN的插头，选对插头，找到车辆诊断插头（一般大部分在方向盘下面左右两侧）然后进入系统，里面如何操作需要看操作手册，并不是每一种检测仪器的操作都一样，而且不同车系在诊断仪器里面显示的操作也不一样，需要选对车型，和药所要进入的系统，有的比较直观一看就明白是什么比如ABS 气囊 发动机控制系统等，有的比较麻烦比如大众系列的需要记得通道号，当然手册里面也有注明，这些都需要对汽车的了解和对诊断仪器的了解才可以做到，并不是会用诊断仪器即可。

Car fault detection device to see what the corresponding car system, different car system corresponding to different plugs, the current market is more OBD2 and OBD2 CAN plug, select the plug, find the vehicle diagnosis plug (usually most of the side under the steering wheel on both sides) and then enter the system, what operation needs to see the operation manual, and not every one. The operation of a testing instrument is the same, and the operation of different vehicles in the diagnostic instrument is not the same. It needs to choose the model and the system that the medicine will enter. Some are more intuitionistic, such as the ABS air bag engine control system and so on. Some are more troublesome, such as the needs of the Volkswagen series. The number, of course, is also marked in the manual, which requires understanding of the car and understanding the diagnostic instrument, and it is not a diagnostic instrument.

注意事项

Matters needing attention

当汽车故障检测仪读取不了汽车电脑时：

When the car fault detector can not read the car computer:

检测仪的检测插头与车辆检测座接触不良，清除干净插头和检测座再试；

The detecting plug of the detector is not in good contact with the vehicle detection base, and the clean plug and the test block are retested.

仪器软件内部故障，对仪器进行升级后再测，仍无法检测可与厂家联系处理；

The internal fault of instrument software, after upgrading the instrument, it can not be detected and can be contacted with the manufacturer.

检测仪、数据线、检测插头、车辆检测座未正确连接，重新检查连接。

The tester, data line, test plug and vehicle detecting seat are not connected correctly, and the connection is rechecked.
