Lexia Connection Problem Help

Hello everyone, regards friends, I am having a connection problem with my Lexia device, the computer sees the device, it sees it in the Diagbox program, when I try to connect, it reads and recognizes the VIN number but it does not connect, it gives a warning as seen in the picture.

If you have an illegal version (AliExpress), don't try to login, put the internet connection off.

Yes, I bought it from aliexpress. But when I try to connect, I don't have an internet connection, but it still doesn't connect, it reads the VIN code but doesn't proceed any further and gives the warning seen in the picture.

You did not specify the version of the Diagbox. Otherwise, during each installation, the Interface Checker program is also installed in addition to the Diagbox. With this program, you can test the probe.

By the way, when reading the VIN number, the relay sound is heard, after reading the VIN number, it does not proceed any further.

You can also try to put the vin number manual instead of scanning

I even tried connecting by selecting the VIN number and vehicle model but unfortunately it doesn't work, I don't think the problem is due to the way I connect.

Just a thought (and I am NOT saying this is the cause of your problem), but have you checked the fuse that 'manages' the diagnostic port? These can fail, and once it has you cannot connect to the ECUs until it is replaced. I do not know which fuse it is; you will have to check the owners' manual.

I also use 9.85. If your Diagbox can read the VIN, then the OBD port is correct.
Have you tried to start the interface checker? It is essential that the rest can work.

When I connect my Lexia device with psa interface checker v3, it does not see any problems and even updates it. Currently, Lexia version is 4.3.7

It seems that Lexia and Obd port are fine. I would try another version or even the same 9.85 but from a different source.

Tried on 9.85 and other versions and on other computers and different devices, the result is the same, it does not connect.
