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. To avoid the traditional automobile fault detection instrument needs to consult the fault in the specification table of trouble. Including heavy trucks, light trucks, buses and construction machinery, they 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, portable, easy to operate, and cost-effective. It is suitable for owners or drivers to use cars exclusively and accurately. The user connects the device to the computer diagnostic stand, and can read or remove the faults in the automotive electronic 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, we can determine whether the parameter is abnormal.
