Volvo S40 of 2005 2006

For the car was going and suddenly stopped and not buelbe to start. We put the computer of a friend and the only thing that comes out is that ai a conjected module and failure in the line can 3. And I do not let the computer into the car.

Hello, it sounds to me that there was a collision or clash of messages in the Can3 line, similar to when the Windows is "paste" there is a conjected module or in a cyclic activity ... Test disconnecting battery several hours, then connects everything and igniting it, returns to scan. If it behaves the same, what I would do would be to reprogram the conjected module, perhaps the software is damaged or ancient, if you solve the problem stories, so we all learn. Greetings.
