the cock v54 give me a hand

hi, I have tried to read the ecu of a ford fiesta 2007....SID804 7S61.....I read id, to the met? reading I feel a smell of burning and a little smoke comes out from the chicken, taken from the panic out all the cables from the cock, I open the cock.... the integrated U-20, MAX485 ES, and literally roasted.
I ask for help to an expert and he tells me....try to read the ecu that works the same ? happened to me and it works the same for both reading and writing,

I try again to read, heck it works............ id ok, ori ok ...but then this built-in that serves...............? involved in DBM? or another method ?
viringrazio in advance of your responses, it would be very helpful to understand what is the use of this integrated circuit, without the master ? a bit difficult, I entrust myself to you experts in the field.

a dear greeting
Nico

certainly not'? a security component,but being logical ports has to do with the management of signals definitely of type binary.

maybe x your luck and only burned, but not stopped, and then still working

I bet that you have not used that adapter where c'? written minigender yellow...

no I have not used the adapter yellow, and he is the cause of the damage ?

it would be useful to understand the function of the integrated....and when it does its function...... you find a wiring diagram would not be bad.
hello

and Transceivers.

Sure that function the same but now you can not pi? do the renesas,that the adapter you have to use it always in serial like ? well specified in the program

excuse my ignorance, and from the little that I have taken this passion, what are the renesas....

are a model of the ecu... usually used on car asian

ok thanks, I need of the lesson.

but when you use a sw read what is said in the video? this time, are you ? jumped a component in the cock, but you could jump the ecu, you can have a flashing warning on that adapter, and I have read, mhaaa!!!

gi?,with the ecu not to be trifled with...

thank you to all of the questions.
greetings
Nico
