Technical Buy: CV-Joint with ABS ring

Hello everyone and thanks again for your help.

Bravo II 2007-2014 1.4 T-Jet (198)

Update
Since the ABS-pickup cable was broken and just by hand joined again, I decided to replace this first. (Remember that the car is not with me and 450km from me.) I sent it to me son and he replaced it yesterday.
Unfortunately this changed nothing. The ABS light remains lit. Does this mean that the error needs to be cleared first for the light to go out?

While he was at it, I asked my son to take a picture from the top. (Picture below.)
To me it looks like the ABS sensor "runs" on "whatever/bearing/abs ring" and not next to it.
The local Fiat dealer checked, according to the vehicles VIN, the ABS "pickup" is located in the bearing. Is this something that can be broken?

Is there anything else that can cause the ABS error?
(Thanks for your patience & help.)

I did add a link to a lovely video showing how the abs magnetic ring is buit into the wheel bearing and how lots of people fit the bearing the wrong way round causing abs faults. As pb suggested way back.

After initaly thinking there was possibility of missing abs ring, I also said that I had checked the fiat part number for wheel bearing for your car and it is for the abs type wheel bearing.

Anyway back to your current question.
If the fault has been rectified by fitting the new sensor then the abs light should go out by itself after driving the car a few meters.

the thread "abs - where do sensors pick up signal from" was started by Deonholt

That was where I originally posted the very helpful video link explaining about magnetic encoded wheel bearing seal.

For some reason my reply to you I made a few minutes ago, does not show.
This was in reply to you where you mentioned the previously shared video.

In short ... Our currency in SA is 20:1 Euro. This means everything here is 20 times more expensive than in Europe. I called Fiat SA last week about the bearing and it is available at Rand 1 800 which is a lot of money. This is why I had to try out all other options and then to make sure about the bearing.

My son is going to test the bearing's magnetism with a multimeter tomorrow. I saw the test on a video I watched last week. The magnetic field together with the ABS pickup generate a very low voltage AC. If there is a voltage, do the same with the other front wheel and compare.
Here is the video showing how its done:

So my hope is to establish tomorrow if I need to buy the bearing or look further.

Thanks again and please know that I REALLY appreciate your help & patience with all my questions ... but I am learning.

You don't have to buy the bearing from fiat if you can find the correct bearing with the encoded seal cheaper elsewhere.

I think in one of your threads you posted a picture of a bearing you intended to buy.

The bearing does have to be fitted the correct way round , please watch the video to see correct way round. Make sure if you change bearing to tell mechanic which way round to fit bearing .

Unfortunately removing a fitted bearing destroys it . so even if it is correct part but wrong way round it can't be removed and refitted.

Yes there are other ways the abs can be faulty for instance the wiring from the car loom to the abs sensor connector could be damaged. However it is sensible to start with the components that look like they have been messed with ie area around cv joint.


Good luck

Jack
 
Hi Deon,

just watched the video you linked.

Very good video explained his checks well.

Yes great idea for your son to check for a.c. volt output from abs sensors .

Fingers crossed you will get to root of the problem .

Best wishes

Jack

I will have to search far & wide. I don't think I will find it anywhere else but I will search for it.

So my son did the AC-voltage test. Could not find a reading on either of the two front wheels. The diagnostics only showed front-left. I think the multimeter I bought him can not read fine enough. It is one that can read down to 2 decimals, millivolts.

Probably can't react fast enough most of them have fairly slow polling time (I believe that the correct term)
 
Did you get to the bottom of this problem?
If yes What was the solution?
