View The Full Version : 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

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

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...

leo_sg

you need to read the component with the programmer

I left the car to car electrician. Now around the web I see that some unit for my car is(about 150€), from what I understand if I had a controller for my own then I should still get it to reprogram and assemble. More or less these two transactions, how much they can cost?they are in the north then I already know higher prices. I would like to have a clear idea when I called the car electrician so I know if you give him the ok to find him this ecu or not.

Last thing: but it is true that the control units can support a maximum of three accidents and then can not restore?

tabs78

The electricians called me, said that, according to him, it is the control unit but not sure. Damn

tabs78

Update. Put on an ecu used. Finally you can not enter into the diagnosis, but the car electrician says that he has already a crash, says he does not know reset it and called Fiat and they do not. In my area of Liguria can not find anyone

Today, I try to get a photo of the errors.
Him on the phone told me that finally you can not enter into the diagnosis but is also an ecu already crashed and should be acknowledged.

tabs78

Is there a way to see if you can reset it?

you sure you can reset

tranky

You are virgin and you can also upgrade to the latest release sw if available.
Let us know news

Alessio93

you could benissimamente recover your taking a e2p new , writing a file, clear the memory is all returned to normal

tabs78

Thank you for the answers.
Then, remembering that I am a layman, I ask for clarification:
1 the fact that the old do not enter into the diagnosis and this provides a datum that will almost certainly exclude the possibility that the problem was of another nature? (I ask, because knowing that you're not magicians, and seers I would like to make the right choice and continue the path that I have taken, that is, not to put the unit new. However, if I solve, then I'm going to spend a lot more).

2) you say that my can you recover, but then what might be successful for having impallata while I was walking, and make inaccessible the control unit to the diagnosis?

3) at this point, assuming you have both restored what on earth?I remember the one that crashed is the model that damage now in Fiat for my.

4) can be repaired by sending it only the ecu?in case anyone here is doing it?

Thanks

Data crash stored

I found a very prepared that the phone has created me another doubt.
He says that the ecu that I found could have more airbags or less my and then I would always have the problem.
Can?the model that damage now to my frame is to

tabs78

resolved, clear the ecu that I have found and installation failed.

you investireste 50 euro on the old for a reprogramming?

tranky

For 50 euros we comprereil a cock and I would do bdm personally.
