Failure of ABS, ASR, EBD Alfa Romeo 147 1.9 Jtd 16v 140 HP

[mcjtd]

on some of the new fiat bravo and croma there was a problem similar to yours that the problem was a defect in the brake pedal, which in some cases was still braking the car and sent them to tilt at all the abs,now? I don't know if it can? be the same defect is also on the 147,strange for? that alpha is not sapppiano nothing sometimes parent companies, sent out a circular on the defects of their products in their own workshops,at least to me every so often they send these circulars

hello McJTD,
You know, is there a software that can eliminate these errors in a definitive way, or a wiring diagram that might explain where is the rel? of the ecu?
watch now as now my priority? ? only operate this damn abs why? The car the usa my girlfriend to go to work, and since this goes 120 miles per day until I get fixed anxious and worried. I hope can understand me!

[mcjtd]

the problem ? that if you do not eliminate the source of the error is no software in the world can? delete perpetually the dtc error for the rel? and electric diagram and I believe that almost all the workshops are equipped with a good datasheet c'? it should have
for the rest, I understand and I tell you that I would entrust a car without any safety control is functioning in the hands of someone let alone a person that I care about.
unless it is strictly necessary and obvious.

[Ivyxeddu83]

The problem is that c'? my parts ? all of the workshops except the houses of the mothers, do not update.
you think that my mechanic still uses a self-diagnosis of 2003, as he says, "so that works use this!!!"
? obvious that the software and the hardware, go ahead and you also know that they make them more and more? modern and sophisticated, therefore he is the one who trade ? a mechanic electricians, Ca--OR up to date! I don't want to tell tales, but these days I'm reading the hard discussions that there are in the forums, and I can say that here in comparison to my parts, they are 10 years more? next!!

When you have problems of the genre, and diagnosis errors of the genre, rel?, pump and strawberry variety, excluding the sensors in the wheels, normally I lose very little time and I go to some of my demolition of confidence and I buy another group/the abs pump, of course with the same code and with small sums of money to solve the problem. Needless to stra them to try on a broken piece that in the majority of the time, don't repair anyway. Or if you want to do things well, there are companies who review these components and the prices are decidedly inferior to the new one, in the order of 1/3 of the cost.

PS: your not update with the instrumentation, but caxo for? you will pay well... will be? well as dumb, but I from my clients, I have never taken money for only the diagnosis, if not after having adjusted the car.

[Ivyxeddu83]

here, however, just the fact of entering in the workshop and disturb 10 minutes are 50 € of course the pi? the repair, if not then we can combine anything as in my case, the price remains the same, the cio? 50
tell me one thing you seem to thieves?

[mcjtd]

nooo....it doesn't seem like much thieves......are just mariuoli licensed!! apart from the fact that a diagnosis is 50 euro and a theft because by us the maximum that I have heard for these things are 25-30 euro and speaking of workshops, where they work "with the white gloves" but then, with what courage and with that face you ask for money-just because of you and attached to a tool,which, among other adessso you pull behind 2 money,and even you cannot solve anything??but if you f? an oil change from your party to pay then you have to take out a mortgage?? don't talk about it if you need to replace a motor, maybe a truck....you have to sell a kidney and half a liver?
and anyway back to talk about the problem of your car I thought you saw that ? the second component that fails in the same way as the first problem, perhaps due to some failure in the brake system that is "superlavorare" the abs-asr, and therefore, the relay of this if he goes for a little easy...among other things, reading the almost accident that you made me think that there is a greater braking force at the rear of what must be to the contrary in any situation....but not ? if you have any brake caliper on the rear that tends to hang maybe when you heat up a p? the brakes??
or do you have the hand brake on a p? the most "pulled" of the usual recording?
and, especially, in which brake fluid do you use??

Check the brake booster IMHO!
Before you have the problem you had to case mounted on the wheel? I ask you, why? when I was working in a factory authorized Alfa-Romeo (I'm not a repair technician, I was involved in emc?, order management, etc.etc.) I remember that they were resolved 4 or 5 cases similar to yours with the replacement of the sensor number of revolutions that could not ritararsi following reassembly of the wheel of the standard diameter.

hello Mcjtd and hi V. V.
first of all, I wanted to thank Mcjtd why? with the history of the bodies made me smile a lot
for? here in my part ? cos?...however, with regard to the registry of the brakes, I can say that since I purchased the car, I never touched about it. The only thing that I have done to you ? the spurgarle the brakes since? I replaced the entire abs pump. To do this I helped my father, not a mechanical one of the old school, where in order to calibrate the carbs you used a glass of water about the oil I'm currently using The Arexons DOT4 for? I can not say if is good or not good at all.
About the wheel I can tell you that when I have the machine not me ? happened to still have openings, consequently, V. V. I could not answer you. however, that cos'? the brake booster IMHO?
Thank you for the attention you are paying to my case.

if you open the hood of your car you will notice behind the pump the brakes a kind of "ball" circular quite big..what ? the brake booster,within this there ? a large rubber diaphragm of the diameter of the "lung" the same,the ball that I said to you before that ? connected with a pipe equipped with a valve to a vacuum pump in the case of diesel, which is called the pump to the brake booster or pump "depression" by the fact that this pump creates a vacuum,a strong absorption in the lung, brake booster, and this means that as you press the brake pedal this, "auxiliary power" the vacuum created by the pump within the lung makes it light on the brake pedal but at the same time apply a large braking force on the pump..to realize that the strength we are talking about tries to push the brake pedal while the car is stopped repeatedly for several times, you'll see that after a p? the pedal will become so "hard" by crush that will seem, crashing the system in a position that is then put in motion and you'll see that, like magic, everything will return to the norm...that is all...I doubt it for? that is the brake booster to create these "burns the abs-ecu"...did you check the masses of the same more of course all the other masses??
