24V to 12V Truck Adapter for Launch x431 easydiag 2,0ë 3.0 ectr

Hello to all

 

I bought this adapter but I have not put it to work yet, because I have read about this adapter, which has a problem with reading K-line in old vehicles (HD trucks), is it possible that the same adapter can be corrected with an additional PCB, inside, to read these vehicles without damage device, especially for HD trucks that ECU works with 24V, in order to protect the diagnostic device from burning?
