The car decoder, also known as the car fault reader, is an instrument that effectively detects and diagnoses car faults. Since some vehicles require the use of special decoders, you should pay more attention to the vehicle's own information when using a car decoder. So what are the key features of using a top-notch car decoder?

1. Data flow display function

The car decoder can transmit the working status information stored in the computer during the operation of each system of the car, the instantaneous values ​​of various input and output signals, etc. to the decoder in a serial manner through the fault diagnosis socket, and can display it to the decoder. In the terminal screen, technicians can see the working status of the entire car control system at a glance.

2. Reading fault code function

After connecting the car decoder to the car computer through a data cable, the car decoder can clearly display the cause of the detected fault in the form of a code. As long as the technician understands the relevant meaning of the code, he can accurately find the cause of the fault in the machine. , instead of obtaining fault code information through the cumbersome method of flashing the fault indicator light, it not only reduces the diagnostic pressure, but also makes car fault diagnosis more accurate.

3. Use PCM with two-way communication function

The performance of the car decoder will also be affected by PCM. If a line error is found, PCM will most likely replace the value and change the real value. However, if a PCM with two-way communication function is used, the PCM can automatically replace these error values ​​when it receives an error message, and the replaced values ​​will also be displayed on the car decoder, thereby improving the use effect.

Through the above three methods, the use effect of the car decoder can be effectively improved. Of course, in addition to this, the most direct way to obtain the best use effect is to purchase reliable quality decoders from reputable car decoder dealers, and then use various better auxiliary facilities. Make the decoder diagnostic effect better and more accurate.
