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.
