failure aibag, the ecu went?

[tabs78]

hello, I need advice because I do not want to throw away money unnecessarily.
I have a fiat bravo 2009.
Months ago I was fitted with a aftermarket radio, without problems. A couple of months ago and added a small booster, taking the current from one of the cables of the radio. two days ago I saw that was not of the improvements was removed and the cable connected with a mammoth.
Facts 100km are outputs of the lights failure drivers, turned off the machine and restarting it is added to the flashing km.

carried by an authorized workshop have told me that they cannot get into the airbag control unit with the diagnostic.
I brought it from the best electricians in the area and he made me see that even he is able to enter. the rest of the diagnostics, not error but when I test with the drivers test the connection, and after a while says to connect the cable or push better cable.
He tested all the fuses. He tried to pull the battery. but nothing. You can't even align the flashing km(I think it's because he sees the lack of airbag control unit)
says that I have to leave a day and disassemble, and it attaches directly to the airbag control unit.

this last sentence made me doubt. I don't think that we will stick directly to the airbag control unit.

This morning I tried to check what read on the internet and that is when I turn the the lights on airbags are now fixed and it seems that it means that he doesn't see just the control unit.

operate on the plant without knowing where the problem is, it seems to me unlikely, and, anyway, if you are not communicating with the control unit I think it is them the problem.

advice?


I would add that we have tried by entering the radio serial

[leo_sg]

without the radio directly, have you tried?

[tabs78]

You, unfortunately.
I think the radio may have gotten the short but maybe that is a case, as I have done 100km.

I worry about the fact of not having access to the ecu

[leo_sg]

I would check if you get power and ground to the ecu and air bag systems, if everything is ok open the ecu and check if you see anything abnormal

[tabs78]

Thanks I hope that the electricians do it, I don't know how to do

[leo_sg]

Thanks I hope that the electricians do it, I don't know how to do

you do not have a wiring diagram? a data bank?

[tabs78]

No, they are a tapino any unfortunately

Hello, try to riprogrammarla the control unit at times when the voltage of the battery and download the file of the ecu airbag is imperishable...

[tabs78]

I don't know how to do that, I hope that the electricians try. For the purpose of information: as you reschedule if you cannot communicate?has an outlet dedicated to trying to connect to?that fuse is not successful, neither the electricians nor the officina Fiat

Hello, to program it you must remove the ecu and get it reprogram by someone competent...
