VBFs have passwords to view them. I haven't looked through the 7zip archives yet to see if they need passwords. I can't open the 7zips on my phone, and I'm not near a computer right now.

rar. for you

Thank you, it seems to me that I already installed it everywhere and nothing changes

Of course, I don’t understand much, but I already admit the option that the program allows you to read a 256kb processor, and in my case a 320kb processor M30855FW

and according to the table it turns out to change only the starting address, the volume remains unchanged

Take the 120ῼ resistors off the CAN transceivers you don't need them and they change the impedance to 40ῼ. It should be 60ῼ total. The car already has the two 120ῼ terminating resistors ( 60ῼ in parallel ). 120ῼ / 3 = 40ῼ. ( 121 = 12 x 10^1 ῼ = 120ῼ. ).

Add a common ground and connect it to PIN #5 ( Signal Ground ) of the OBD2 connector.

I changed it, and there's no point. I noticed that when reading, the program always shifts all addresses by one bit.
