7. The Mercedes-Benz diagnostic computer shows an unknown communication failure?

1. The failure to establish a connection may be due to poor signal or server failure.

2. The smart network function of the car is in chaos and needs to be restarted to solve the problem.

The car's inability to connect to the Internet may be caused by signal interference around the vehicle or a failure of the Internet of Vehicles antenna. Because the actual car cannot be seen, the fault cannot be accurately judged. It is recommended to contact the local 4S store for detection and repair.

8. How to use the car fault diagnosis computer?

The operation method of the car computer tester is similar, and it is very easy to use. Connect the test computer and the car diagnostic interface. The method is: turn on the computer - select the car series to be tested - select the car model to be tested - select the system to be tested - —Read fault codes, data flow, component testing, matching. . . . In addition, if you still don't understand something, it is recommended to read the "operation guide" first, that is, the instruction manual! Comments to watch

9. A complete collection of computer motherboard fault diagnosis card codes?

Complete computer motherboard test card codes:

Generally speaking codes:

FF, 00, C0, D0, CF, F1 or nothing means the CPU failed

C1, C6, C3, D3, D4, D6, D8, B0, A7, E1 means that the memory is not enough

24, 25, 26, 01, 0A, 0B, 2A, 2B, 31 means that the graphics card is not enough

C1, C6, C3, 01, 02, this combination jumps in a loop Most of them are I/0 broken or BIOS refreshed

Extended information

Motherboard fault diagnosis card: It uses the detection results of the BIOS internal self-test program in the motherboard to display them one by one through the codes. Combined with the code meaning quick lookup table, it can be easily Quickly identify computer problems. Especially when the PC cannot boot the operating system, the screen is black, and the speaker does not beep, using this card can further reflect its convenience, allowing you to get twice the result with half the effort.

BIOS performs self-test on the system's circuit, memory, keyboard, video part, hard disk, floppy drive and other components every time it is turned on, analyzes the hard disk system configuration, and initializes the configured basic I/O settings. After normal operation, boot the operating system again. Its distinctive feature is that the critical components are tested first based on whether the monitor can display.

The failure of a key component forces the machine to shut down. If there is no cursor on the display, the screen will not respond. Then, test the non-critical components, continue to run the faulty machine, and insert the card into the expansion slot when the monitor has no display. According to the code displayed on the card, refer to which BIOS your machine belongs to, and then find out the cause and location of the fault represented by the code, you can clearly know where the fault is.
