The Punto evo 8F2 - inertial switch

[emilground]

Hi, guys, on a Punto evo 8F2 75hp has occasionally an error on the inertial switch that turns off the car. Trying to start the bike part and maybe you will not have the problem for days.
The car does not ? accident-free and the error ? pi status? times deleted with the examiner.
It is possible that the problem is due to a write is not successful in jtag for? then ? been completed successfully error ? Monday? the afternoon andr? where is the drive to realize the person of the problem, for now I just wrote as much as I ? been reported!
Thank you and good day to All

hoping that in the opening it is damaged!!!

the problem presents itself from time to time in the engine diagnosis does not result in any defect. Only the body is shown, the relative error of the inertial switch. Could be a problem due to the first failed write to? the car ? game without any problem after the writing was good and I immediately presented the problem.
Let? as a first test on Monday? a realignment with the examiner, and if it doesn't give results prover? to make the procedure of replacing the ecu on a myth I ruled out? the problem that always left the fans as soon as it was put in motion.
Well, the things more? strange...
as a last test I can upload flash to e2p original, but it annoys me open those ECU

for me, the engine control unit, it has nothing to do, the signal block inertial part of the control unit, air-bag, via can feel the body which in turn tells the ecu the engine to shut down and not go in motion, then I would check also in the control unit air bag if you have errors.

I think I also that there is to come in, to? the strange thing ? the problem of the inertia switch ? had after that ? opened the ecu for mapping. It is a problem that occurs occasionally and not in the same condition, type full acceleration, turbo pressure, high or low etc

hi if you have not solved try to make the steps to disable the fps and see what results you get ? a test you never.......

[emilground]

I have done various tests with the examiner, and now is not pi? no error in diagnosis, not even that of the inertial switch, to? the problem also occurs only once in a month and leaves no trace of the error.
The drive d? a twitch as if he wanted to shut down but not shut off and resumes immediately to walk regularly.
The car they bought used not long before it was mapped, then you will not know if you already? was this problem present or not. Could have sold it for this defect is not resolved. It could also be a false contact somewhere, but it seems strange to me that there is no error stored.
It being happening to several of the punto evo with troubles... type a, which via the control unit of the glow plugs ? burned, in turn, burned the engine control unit ! absurd things

It would be worthwhile to put it back ori to see if you still have the defect?

[emilground]

if ref? the defect prover? to put it back original? I do not think depends on the file. Via serial not it has made me write the V53, then I would have to reopen it and get her in the Jtag, or maybe wait a little to take the I/O Terminal

you with I the terminal can do it safely, but I would check the pin in the ecu of the airbag maybe there is one that does not touch well
