Fiat Ducato 2008 ABS light ON. How I was wrong!... Fault finding and repair.

[@Luzt.]

I have just repaired my ABS, Ducato, 2012. One of the wires of rear right sensor was broken. The place of fault was on a more or less stright section, ca. 40 cm from the plug. The wire was somehow crushed and probably broke from vibration. Having many backgrounds I decided to use 3M Scotchlok to restore continuity. It is fast, water-proof and reliable. Thank you for your video. I appreciate the time and effort you put to make the knowledge accessible for others.

[@LMAutoRepairs]

That's great! Well done! Thank you for watching, for your comment and feedback! 👍👍👍

[@binarybox.binarybox]

It's gr8 how you make sure we can see everything by correctly positioning the camera. I was impressed by how far you go to diagnose the problem. The RR sensor was changed without even checking the wiring. The fault in the wiring looked as though it had been on for quite some time. The fuse box was another unknown and your approach of checking everything pays off. I thoroughly enjoyed watching your detective work.

[@LMAutoRepairs]

binarybox Wow... great that you enjoyed it! Thank you for watching and for your kind comment!

[@lr5037]

Hello Luis, thanks for the video. Regarding the burned wire inside unit, it might be due to the programing in the factory. It is common with the eprom memory that after programin the chip higher current is applied to one of the legs of the IC which causes inside connection to burn, which prevents the content of the memory to be overwritten. It might be similiar sort of protection. I assume that these types of ABS are used on different types of vehicles, so I assume that the units are the same but software that they contain is different (ABS works with different parameters). Therefore after the units were programmed in factory I think that they burn the programming connection to the chip in orver to prevent either accidental overwritting or copying of the software.

[@LMAutoRepairs]

Hi That makes sense... never thought about it! Thank you for watching and for sharing that info!

[@WereReallyRelayCamping]

I was going to suggest the same thing, fuseable link to terminate programming and to stop it being read/cloned etc

[@LMAutoRepairs]

Thank you for watching and for your comment...

[@peeptopeep9277]

I was just about to ask/wrote the same thing, I can remember when I studied electronics that you can get a FPGA which is a chip with multiple circuits on it and the useful circuit is kept and the others burned away(like miniature fuses burned)... I think it’s a cost saving thing so the same FOGA can be used in multiple circuits but just configured differently and no need for a custom chip.

[@sebastiangache2260]

Thank you for the video. I had similar problem. My cable was broken near exhaust pipe. Boxer 2016 Euro 6. You inspired me to solve my problem. Thank you.

[@LMAutoRepairs]

Well done! 👍👍👍

[@richbrett7268]

Thanks i will check mine. Same issues.

[@richbrett7268]

Thanks so much.. Citroen relay in nz with the same abs code - no one here will touch it.. about to send the abs module back to the uk but thanks to this video i will check out the options your show.. i reckon in my case front right wires as a couple of years ago the pad wear sensor wire ripped out and left loosly taped up at the advise of my mechanic. Thanks very much for this video. i learned alot.

[@LMAutoRepairs]

☺️ Thanks, hope you get it sorted! 👍👍👍

[@LI3TOM3]

yea lots of mechanics take the fuse out so the pump dosent work as causes crunching on brakes ,i have removed the fuse myself untill i have fixed the abs problem on many a car ,just so u can actually drive it without brakes not working properly ,it means all four wheel cylinder s work at same time ,,great vid mate enjoyed it have found many faults same way ,,hahaha yea pity u never started from rear haha :) take care

😊 Thanks! For watching and for your comment! 👍👍👍

[@sashamiller288]

OK so I followed your video instructions but I made a small mistake somewhere not sure what I did but now the driver side taillights don't work. So I fixed the problem but created another one .. what do u suggest I do now??

[@LMAutoRepairs]

Check what you have done... Perhaps, check fuses first, just in case... 👍👍

[@Bartezz]

Excellent work. Wish there were mechanics like you over here 👍🏻

[@LMAutoRepairs]

[@Bartezz]

@@LMAutoRepairs ever had esc and hill hold warnings come up (no limping) and disappear after two restarts? Reading it could be brake light switch beneath the brake pedal?

[@LMAutoRepairs]

@@Bartezz Never had that on a Fiat... But had weird things on others due to the brake switch... It might worth for you to investigate it further... Scan it it first, and check live data, that will help you giving some guidance... 👍👍👍

[@georgedart1]

Great video i think this is now going to help me lots with my problem i have the same van with electrical problem. Abs light comes on know again speedo stops working. But noticed a couple of times there has been a smell and smoke coming from the battery straight after the brakes are used im thinking now there is a damaged wire to do with the ABS last night had to take battery out of van because it was smoking so bad will be investing after the weekend. Thanks for the help 👍

[@LMAutoRepairs]

Hope you get it sorted! Thank you for watching and for your comment!

[@richbrett7268]

Did you find the problem? I have a Citroen relay- the last time i drove it with this abs issue - i reversed back in my drive saw and smelt smoke- i thought it was coming from the rear left wheel somewhere.

What is that yellow screw probe you use for continuity testing? Does it splice into the cable or is it non contact?

[@LMAutoRepairs]

Yes... pierces the insulation of the wire... Thank you for watching!

[@alangaudry724]

Great video. Enjoyed how you narrowed down the open

[@LMAutoRepairs]

😊 Thanks!

[@rhiantaylor3446]

I enjoyed your work so thanks again. With the fuse missing I suspect an unintended path was available between the control unit power feed to the solenoids (which are the only things drawing significant current) i.e. from the remaining processor power feed via the small wire that clearly was overloaded. In the case of Module B that wire looked burned but still worked so perhaps it wasn't abused for very long.

[@LMAutoRepairs]

[@nadeemahmed640]

Good job sir but how possible this cause of no fuse and open or short of speed sensor?Both units are at place burnout ?can you tell which pin number?

[@gouveiaclassicos]

Exelent job I teatch new tec and one of my way is ask them to check the integretie of the wiring from the plug to the ecu all the time before replace any component but as we know this is the resault of just replace a sensor because we have a fault code keep up the good work Forte abraco da Colombia

[@LMAutoRepairs]

Gouveia Classicos Indeed... it is a lesson for me to... to start diagnose without taking into account what someone else did... if I would have ignored the fact that the module was changed, that's where I would have started...😋 Thank you for watching! Grande abraço!

LM Auto Repairs Been there got the t shirt to we learn with are mistakes Lol

[@tommyt4062]

I just wanted to say that I only found you channel today but I've already watched tons of you videos and subscribed. Also I not a mechanic but I'm pretty good at soldering, fixing computers, phones and anything electrical really so a friend of mine who is a mechanic sometimes brings me ecu's and other modules to repair. Anyway not to long ago he brought me one of these abs controllers to look at and it had exactly the same burned wires and even though I have very nice soldering equipment and a very expensive microscope I thought the same as you, that is a whole other level, in fact I don't think there are many people alive who could soldering those wires? I actually thought it was alien technology when I first opened it :-O

[@LMAutoRepairs]

Tommy T Indeed... very tricky to solder those... there is special microscopes/soldering stations for this sort of jobs... Thank you for watching!

[@tommyt4062]

LM Auto Repairs yeah my microscope is more than good enough but I doubt that my smallest soldering tip would be small enough and I know my hands certainly wouldn't be steady enough lol. And thank you for the videos, for someone who isn't a native English speaker you explain thing very clearly and in a way that even I can understand, this isn't always an easy thing for people to do :-/

[@allrock1238]

Grasping at straws .. had a break in sensor wiring to the rear wheel speed sensor , if one of those signal wires was either shorted to ground or managed to chafe itself in contact with a wire in the harness carrying 12 volts. The damaged ABS signal lines do they lead to that burnt wire input on the chip ? Someone trying to probe the rear ABS sensor loop with an old low impedance multimeter or 12 volt test light that was capable of flowing too much current into the circuit (less likely) , A Bad ground can also cause current to back flow back through components never designed to handle that much current , I have seen a bad engine to frame ground force high starting current to try find a grounding path back through the sensor circuits , this destroys the fine circuitry in the module it manages to try and find a return path through .

[@LMAutoRepairs]

I would assume that the modules are designed to detect this, either a short to ground or to positive, without causing any damage... but you never know... it is possible! Thank you for watching!
