they passed the scanner because it presents a fault that goes out minimal, courageous rise that indicated according to the technical problem with the computer, we sent it to review a workshop specialists in computers and the result is that the computer is good.
After the mechanic receives it, and nothing that turns on the car, we ask the favor of a man who has an equal car, he lent us his computer we put it to mine and nothing then exchanged them and nothing that lights mine. Then we call the workshop where the computer was checked and the technician commented that this computer does not work in another car unless the same wiring and swichera mount of the same car.
