Re: Abs trouble

I replaced the whole bearing hub with a new one as the old one had a perished ring on it with bits out of it. I couldnít get the ring separately as the bearing was fine.
I changed the bearing last week and Iím sure the abs light has been on for a few months before I decided to do anything about it.

The answer could be in the above statement.

Here's a theory.
The perished ring gave unusual signals, so the ABS light illuninated.
You replaced the bearing with a non-ABS one, so the light stays illuminated.

Next step is to recheck the part you bought. Check part number/spec to see if it was ABS or not.

Re: Abs trouble

Just checked the hub and it is abs. Checked the hub listing / no. and it is the correct hub for my vehicle with abs.
Got the Multiecuscan and cables with modified elm327 and serial port does not exist, so weíve spent all morning trying to sort out Multiecuscan with no luck.. been trawling the internet and still have no luck.. I seem to be stuck now until I can sort out the Multiecuscan.

Re: Abs trouble

screenshot of the device manager might help


is it hiding in the USB tab


I take it we are talking about the USB type cable and not a Bluetooth or wireless type

Re: Abs trouble

Meanwhile I borrowed my sons panda, swapped the key barrel, ecu and body ecu and the abs light still came on.
I put my components onto the other panda and everything worked fine, no abs lamp.
So at least the ecu is good.
Iíll check the sensors on the other panda tomorrow and compare them.

It seems you've been swapping bits and not really looked at the cause of the problem.

The U error codes you say it showed have nothing to do with the ABS they are network errors, may have been wating on the ECU for years to be cleared, the fact that they have not come back means they are not a problem u1600 is a key issue u500 should not exist as it does not have 4 numbers. The thing is it looks like you have been reading the engine ECU and not the ABS ecu.

You will need a program like MultiECUScan to connect to the ABS ECU to see what fault codes that module is recording. If the ABS light is on then the ABS unit will be recording its own errors.

You could well find you've been swapping wheel sensors and there is nothing wrong with them and the ABS ECU has recorded some intermittant fault that needs clearing, or you have a broken wire up from the wheel sensor, who knows but the only way to tell for sure is to get it plugged in and read the ABS errors.

Re: Abs trouble

Have a look at this thread:
https://www.fiatforum.com/panda/352156-fiatecuscan.html
Particularly post #5 . Follow the instructions carefully to set up the computer to talk to MES.
It took me a long time to get it working initially, some time ago now, but since using that sequence it is reliable every time.
(Does need the drivers installed and working of course)

Re: Abs trouble

It really is time that MES was made to run on Apple MacOS. It's more work for the developer, because Apple wont let them supply stuff that wont work without a degree in computer science.

There is however the rented version that runs on iPhone iOS, but MES website is not clear if that version has the full function set.

Re: Abs trouble

Finally got this sorted... the brand new elm 327 cable turned out to be faulty, the seller sent me a replacement and I plugged it in and it worked straight away.
Fault was rear right sensor. It already had new sensor and I changed the hub for the new one Iíd put on the left and still had fault. I tried continuity from rear sensor cable to the abs unit and it showed that both wires were touching. I removed the trim inside the rear seats area and pulled the wire up. Their was an airline crack in it so I fixed the wires and voila.. abs is working.
I did try the sensor test with and without spinning the wheel on the other panda and it showed no reading as well. I think these sensors are different than all the internet blogs and YouTube folks have been saying.could anyone shine a light on this querie?
Thanks for all the assistance and yes multiecuscan would have saved a lot of time and money in the long run.
