I've fixed literally 100s of these. 99% of time it's the cluster. Odd time it is that earth. Usually the earth if it's constant no-comms and when customer says it's intermittent (or problem started intermittently) it's the cluster. First job is always to resolder the connector on the cluster. It still could bounce on you as the cluster has been out and this helps crack the solder anyway. Focus, CMax, Transit etc. all the same from about 05 to 11 (maybe more). Don't worry if you get U1900 code from cluster after a fix as that's just the cluster not liking the added traffic from the scanner. Also, you were right about the ABS thing. A lot of stuff now has high speed CAN for comms and a different line for diag. Good vid 👍

Nothing more satisfying than finding that broken wire. Great find and repair . Thanks for the vid

Thank you Sir for this video it was really helpful, at the beginning I thought that it was the PCM you did the right diag to determine the issue. This channel is one of the best channel I am following. 👍👍👍

Exactly my problem. Had the air box out as I was doing a couple of jobs and must of knocked a bad earth connector. Sporadically lost comm's with multiple systems at once and knew it was a loom issue. Video sent me straight to the root of the problem.

Hi my Ford Focus 2008 is doing the same thing I had locksmiths here and moble mechanics Finally it's at ford and they just got to it and he is saying the INSTRUMENT CLUSTER may be the problem wow I wish it was just a ground wire like what you found awesome!!I seriously enjoyed watching you Thank you Joanne

What an odd place ford placed the ECU. Looks vulnerable to me. By the way, your fault findings and rectifying is really good. Learnt a lot from your videos. Keep us updated with your new videos!

Just to say a big thanks for this video. I've had the same problem on my 2008 MK2.5 Focus 1.8 diesel. I had reflowed the instructment cluster solder joints a couple of times and replaced the the main earth cable but didn't know there was other earth cables underneath the air intake. Three connections all intact but in a bad need of clean. Once cleaned engined started first time. Codes cleared and hasn't popped up again. 🙏

Finally I had the time to watch it mate, busy weekend away with the girls and internet wasn’t brilliant ☺️😊... top job as always and great find 👍👍👍👍

Thank you, I have a very similar fault on my 10 mondeo mk4, this video gives me something to look for and check! Hopefully I’ll find a bad ground and not a corroded loom

Well done! Helpful video, hope i can go to your shop one day for my car electronic issue. Thank you & more power....

Thanks I have the same car in shop, similar problem but intermittent. Allready checked battery grounds but not these ones. Not knowing the pcm was in the wheel arch. Will check tomorrow and reply back!

Great job! always I have come to learn from you. Thanks very much!

That was a great fault find to watch ... well done ... very satisfying

This is another great fix. (No parts cannon) And a good video.

Excellent work and very informative. Well.done.

Fantastic content every time 👍

Fantastic detective work.

Great video, had the same problem but with mine it was relay 13

good video, some very useful information here including from other posters, just shows don't be blaze' about the grounds they're usually a fairly easy check, thank you.

Tanks voor het werk en voor video's 👍

Absolutely lovely... Great job mate.

Thank you very much, perfect as always...

Thank you for another great video!!!

Got to love some of the faults of Ford vehicles. Just found your channel, nice work

Good job. 90% of problems in electronics are their critical contacts.The hardest thing to find is where is this bad contact. Greetings from Ukraine

Great investigative work.

You forgot to tell us if you still have no comm with ABS in IC live data. Thank`s for videos! Keep it up!

Another interesting video, Luis.

Great stuff as always, top man

BCM is new (build date 2018 and VDO didn't own Siemens in 2007) so I'm guessing by new snap bolts on the BCM cover that Ford already replaced the BCM to cure this problem. Snap bolts can be drilled to hammer a torx bit into the hole to unscrew. Looks neater

Great content as always . Sometimes the little things do big trouble , like a bad ground

THANKS MAN, NEW KNOWLEDGE FOR MYSELF.

excellent work partner Alex de Uruguay

Loved your video 👍👍

thanks for video, great job.

Brilliant as usual

Great search for the rootcause hope to find something similar on my 1.8 TDCI 2005 Super

Good job men!

Good work.

Hi great video very in formative .I have this problem of engine system fault that only occurs when the ambient air temp is above 33 - 40 deg c in our summer time.This has happened now three times from 2019.Has not happened since,as we do not use this focus when its hot. Any ideas on this particular senerio.

Clever boy good job!

good work ,keep it up.

Thank you so much for the video massive help thanks

Good job. Perfect.

Et voila!!!!! super recherche, i love ford for this😇

Great stuff mate...

A very generous gift from a good friend thank you very much for the video

Big work. I hate ford system 1600 1800 and 2000tdci bosch or Siemens system have a lots of fail IC gem and abs.

Great job freind. ☺

keep the hard work :)

I have ford smax mk1 2008 2.0 tdci and have this same problem any suggestions where to look and where ecu is located? what color wires are for ground or if you have link to diagram all help appreciated as ive just been stripping all the tape off the wiring loom in engine bay looking for breakages.

Thanks ,very good.

Ciao grazie tanto per il video ho riparato la mia auto grazie a te mi sono iscritto al tuo canale.

That's a job well done. I was pretty sure that fault would've been at cluster as they have bad solder joints. Well at least I had mine fixed when dash occasionally died on my Mondeo (then again it didn't do anything with immobilizer, it ran just fine). Btw it's kinda irony that wiring loom connector was in quite angle and wire was short. Connected to shaking engine it just wore out. I'd bet that it would've never happened if loom would've been connected straight at factory. Little things that can kill modern car.

Bravo bravo tank voor video

Good work littel problem but made big issue

Bravo !

Thanks same problem or ford focus 1.6 dtci 2005 year.No brocken wire bat corosion probmem.thanks

Thank You!

Interesting. I have same issues on an 09 1.6 TDCI focus. Appears that PCM is dead. Can't scan it. Car wont start. U2150 DTC. Checked grounds and +12v at PCM. Seems ok. Can see CANBUS at PCM too. I will check earths anyway, but maybe my PCM has died... (Checked IC soldering first but made no difference)

Great thank you

I absolutely love when you say absolutely lovely ahaha

Bravo! Stable adherence to the methodology led to the result. It seems to me that the AUTEL is slower than other scanners. Is this the way it seems? I look with interest! Denis.

thanks for your valuable video! never thought about checking with the other keys! if anyone can tell me, does a power steering failure message and the car not starting on a ford focus 2006 2L TDCI could be the same issue as here, lack of ground? (if I understood the whole video correctly, hey I did watch it twice lol) my car just started doing that, when you put the key in,nothing all dashboard lights turn on and it doesn't start, however if i move the very hard steering wheel around and it clicks as if locked and try to start, it does start sometimes. it was running just fine a few days back though.

Super!

My instrument cluster on my 2010 focus completely lost canbus comms even after resoldering the board and sending it away 2 times to supposedly get 'fixed'. Eventually just changed the instrument cluster from a scrap car and programed it using elmconfig

GREAT JOB SIR! It is same with fiesta 2012 pin out for the ground? My fiesta had same problem,no data,no connection ecu,blinking imobilizer,do you have pin out diagram? Or wich pin out for the ground and positif on the socket should I check sir? Thanks sir!

Hello.I also have a Ford Focus C-max from 2006 with a 1.8 engine.I have a problem with the on-board computer and I think you know what the cause is. please help me with some advice.

O known its an old video bit still a Great video and insight into troubleshooting. I have a galaxy mk3 2.0 diesel with a non start issue. Has been looked at but no one has an answer. Lights come on but it does not fire. I only hear a click from the rear boot area. I don't know where to start. Over the weekend i will look at the fuses and connections. Any advice is appreciated. Thanks

What happens on your dashboard the temperature gauge soon and see start is goes halfway what causes that

Thanks another great video if you could use diagostic that's cheaper ie for scan so d I y e r s can attack the problem without buying a expensive tool love these type of videos was fairly easy but how did u know which where the powers on the ecm if you had not seen wiring diagram thanks

Thank u

Merci beaucoup

Hi sir, what is the problem of the ford focus 2010, headlight always on, ac not notworking, remote not working

Sorry to bother ye can get pinouts or digram ford focus mk2 2009 1.6tdci I see that you have power at g4 brown plug can bus and ground and on bottom plug are the same on mine do you where or if in mine thanks

Very good very good very good😎

👍

where do you get the diagram?

Hi what scope are you using in the video thanks

I would like to ask for some help please . I'm having wome problem with my w211 e270 . its imported from UK but it has been converted to LHD . Mechanical , engine and trasmision is is fine . But i'm having some trouble with some modules like , door modules , seat adjustment , etc .i guess the electric shop guy messed up the wiring . Looking at WIS/ASRA its hard and not that much easy to undestand . Do you know some trusty source for the wire diagram of this car? . Autodata3.24 , vivid workshop has nothing that helps,Hellagutman is super but not accesable from my country

did you see the simplydiag vid the outer day . the tip tipm unit growing via the rear wiper motor

Hi I have the same issue but with no power to any of the ECU plugs. All fuses are fine any ideas what it could be? Thank you

I have high pressure fuel rail sensor problem coming up on my cmax 2.0 titanium. Starts after 3 tries , how reliable is this computer diagnosis ? Thanks

I have same fault one reading 4v at key

love your work,,how do you price your jobs cause I know you probably had a bit of time in these fault finding and time is money especialy cost of equipment

Hi, I have a p060c permanent and a p1000 intermittent on my ford focus c-max 1.6 petrol 2004. It's a big headache. No one could sort it. If you have any hints please, please let me know . Before this issue, drove perfect *, parked for 10 minutes and after won't start. Sometimes it starts but after 10 seconds the engine stopped without rattle. Thank you in advance.

Sir what kind of software that you use for wiring diagram and ecu read

Bonjour quelle son les numéro de pin pour le 12volts

Sir I have bmw E60 5series the problem is I replace the instrument cluster and the services lights (brake pads...engine oil.... and others coming yellow Triangle in dashboard how can program it???i am using icom 2

Good day, I see you know each other. I have a Mondeo mk4 2.2 tdci. I replaced the battery with a new one and since then the car won't start. On the converse, the immobilizer is active and the engine malfunctions. Forscan won't connect to pcm. Could you help me? Where is the problem.🍻

Hi what is the model number of the reader you are using on the ford?
