Xhorsestore engineer replied:

Is the line connected to the tablet abnormal? Try to check. The device shows that the self-test is successful, and the chip cannot be connected.


User Feedback and follow up: I has tried both cable. And for sure, correct connected. I worked with the key tool plus over months without any problems and I have here more than 10 additional Tools (from Autohex, Hexprog via BMW Explorer to Kess, Ktag and so on). So you can believe that I know what I’m doing.

Xhorsestore engineer reply:

Can these lines not read the chip? All the same error message?

Has the DB15 of Key Tool Plus ever been connected to the wrong cable, has it ever been shorted? If the connection is normal, there may be a problem with the IO port of the Key Tool Plus, and you need to contact the seller for repair.
