Ford Focus MK3... Multiple electric faults; one root cause! Fault finding and repair! 

That was a challenge Luis. The toughest jobs can be the hardest to earn money on, it doesn’t make sense. Well done for your determination 👏👏👏👍

Original mechanic bypassed BCM to get that car out of his shop. The way he chopped up those wires might clue us into how frustrated he too must have been. Great video

Just a tip; when you do an autoscan, instead of then manually going into every module to read the actual codes, just push REPORT in the bottom left after the autoscan is complete. It saves time;). Love your videos, learn't a great deal of them, keep up the good work! Greetings from Sweden

Great job! It must be satisfying after correcting all that crap from the previous 'technician' and deliver the car to the owner while you can tell him that you solved all these issues.

What a professional you are. Shame there's not more like you in everything in life 👍

Watched the entire ideo video . How could you not ! What a mess but your persistence and intuition paid off . What a mess , but hey amazing job . Keep them coming.

Note to self: dont complain about your job; others have a much more difficult job! Well done for unravelling that mess!

You did really well to sort that out. Pity you couldn't sort the BCM as I noticed your enthusiasm when you were working on it I could tell you wanted to sort that that's what I love about your videos fix rather than buy.

That “oh dear me” at 48 minutes killed me 😂😂. Such a familiar feeling

Thank you for this video, everytime you make one of these is a blessing as a learning mechanic myself, i hope you continue making these as long as you can :). Suggestion: put all the dtc codes you encountered or at least the most important in the description or title, so if someone searches (like i do) for the codes this video will come up as suggested because im sure with a video of yours the code can be 100% repaired with the way you test and search for faults, thank you.

You did really well Luis!! Always a pleasure to watch you work. Thanks Mike

Always amazes me the lengths some people will go to bodge something rather than fix the problem. Seen some jaw dropping workmanship myself that probably took more effort than getting to the bottom of the original fault.

Hi ! I thought you couldn't surprise me anymore, but you push the limits every time. Thanks

OMG what a journey! I admire your perseverance, I would have given up after seeing all that dodgy wiring 🙈👍🏻👏🏻

Very well done, I admire your tenacity. I did watch it all the way through.

I watch all your Ford Focus blogs. Had a "No communication" fault on mine for 4 years ago. Nobody's seems interested in taking a look. Every summer I have a fiddle with it! Hoping one day you'll produce a blog to give me a eureka moment 🤞

Well done 👏I watched it to the end ,I just hope the guy who messed it up in the first place appreciate what you did. 🙌

I watched the whole video Luis! Trust me it was thoroughly enjoyed!

Man.. that other guy created a complete mess. But it was great to see you did finally fix it after all that effort.

I smashed through the whole video. Nice work matey. What a disaster it was to start with!

This was the worst/best example of bodgery on any of your videos, absolutely gobsmacked how someone could get themselves into that mess!

Thanks for the video. We, that like your work, do watched untill the end. This could be an easier original fix but was transformed into a nightmare.. crossing Wires in the main box... Really !!! Regards.

That was unbelievable. A spaghetti mess of wires below the power distribution.... This is like asking the most talented chef to unscramble an egg...

The phrase; I am up to my eyeballs in Electrical problems comes to mind. Nice one Luis, I hope you charge the owner an Arm and al Leg. At least for the time that the car stood on your property. Looking forward to the follow-up. greetings from the Netherlands Akko

OMG !!!! you sounds Just like me and the begining of the video !! I admire your courage !!! Stupid stuff all over and the programing seems to be à pain in the ass !!! Thank you very much for this video !!! Keep up the good work !!!

Nice video. Watched every minute, good diagnosis and repair.

I watched it all Good thing's don't come cheap Your knowledge help alot educating us upgrade our skills

What a challenge that was , well done for sticking with it your knowledge got it sorted in the end.. when's the next focus ha ha

Realmente não há dúvida que o teu trabalho é realmente de qualidade. Ambos sabemos que mecânicos de renome não nos chegam aos calcanhares porque quando chega à parte electrica e electrónica, muitos deles apesar de terem bons scanners, o problema é não saberem interpretar os erros que são mostrados. Enfim. Vai daqui de Portugal, mais concretamente dos Olivais em Lisboa, um forte abraço para ti. Continuação de um bom trabalho. Fica bem e tudo de bom para ti e família. Abraço.

You deserve a medal for that bro.... I'd have reported the car as stolen, and they would have found it on some roadside engulfed in flames!! Hat's off to ya mate.

You sir deserve a medal 🏅 for that effort !

Well done for sticking with it buddy👍🏻

Great video 👍 When in doubt check eBay for how common part's are listed this is usually an indication of fault's on particular cars,hope the owner appreciates you saved his motor😮

Top job again Luis. Some dudebro backyard "mechanic" muppet must have thought smart ground signals from the BCM were the devil's work but he was clever enough to "fix" it :D He should present his invention to Ford/Visteon, those guys there don't know shite....

You must have patience to do this kind of crap job , so many punters do not understand the modern complexity of vehicle electrics , as you found out on this one , glad you got it sorted , I hope your invoice covered your time

Good video, very good. I like it alot. Complete evening movie. Thank you Luis.

grande paciência, competência apesar da duvida,video visto até ao fim,👍👍

Very nice job!!! Please continue to do it !

Well done again what a mess to sort out 👌

brilliant vid lui lots of good info

methodical and thorough as usual well done louis like i say if you dont know what it is dont f**k with it

Hi thanks for the video. You definitely very patient

Thank you for another great video!!!

That one was an absolute whopper Luis !! I was glued watching for the full video. Possibly one of the most impressive so far. I honestly believe without your intervention that car would have been written off pretty shortly after this. That wiring job on the under bonnet fuse box was absolutely grim !! Sincerely hope you gave a decent sized bill out for that one !!

We’ll done m8, you have the patience of a saint 👏👏👏👏👏👏

Fair play to Sir, if that had come to our workshop and i had seen that lot in the fuse box it would of got fucked off out the door hats off

Great work!!!

Great work again I looked at all of it it’s like looking at a movie lol

superb video , you are a genius

You are awesome no give up patience of a saint 🙏

oh my god that really was a fire trap i have never seen anything like this in over 50 years.last comment my friend i will now watch it all but waal

I got this far did enjoy the video,you can here the frustration,

I got to the end very impressive what you do

Great video, I watched it all the way through. There's not many people like you any more. Every garage I go to they just throw parts at it. What part of the country do you work from?

Great job 👍

I watched it all ...cool fix again

Good work

You are Fantastic, Great video,thank you man! Hvl

Hi nice informative video if i have virginised ecu can i get all data using forscan uploaded

its really dangerous what this guy done with the wire ,if anyone has ever been in a car when even just one wire burns itself out the fumes and smoke are immense ,if while driving it happens good chance u crash the car ,i havent even watched the whole vid yet lol ohhh boy well done sir i take my hat of to you ;)

If you dont do it then who will do??? Great work man I love you bro Thnx

That engine junction box 🥴 You do like a challenge, well done for sticking at it. Out of curiosity how much were the chips you purchased?

bom dia e bom trabalho doutor luis

HELLO LUIS,ONE QUESTION PLZ,WITCH COMPONENT SHOULT I READ MANUALLY FOR CP COMPONENT PROTECTION BECOUSE I WANT TO CHANGE MEDIAPLAYER 1 on audi q7 2006

Great job

Great job as usual Luis, but this is a mega job, what do you charge the client ;-)) aaaw ....

Did you check all the relays on the original module ? Cheers for the video too

Fantastic. Did you try to code the first eBay module? Many used part numbers are never sold as new parts counter parts so used is a gamble as it may or may not program. New can have all its own issues like being too new for your software.

WOW 😲....a GREAT video.... Thanks for that.. 😴😴 i sleep 2 times during de video and backwards ...this video for mi dont have 1h 21m 06....but 2h28m.....😂😂 but i loved this video.....

Respect brother RESPECT ✊🤟 I watched it all the way through I know your pain and all I can say is respect Your one of the first mechanical technicians I have found who don’t cut corners and always double and triple checks shit before being the usual good old parts changer or hack the shit out of things until they finally pass it onto the next person aka dumb arse me who can’t seem to stay away from the cars and trucks and all the other things that go into every one else’s too hard basket and me being me who just can’t quit lol figures out the fix and pull my hair out and swear my head off and smash up my body climbing all round the vehicles or whatever lol you know what I’m saying I frign hate seeing people who have no idea and I mean there is no idea and learning along the way but then there is the no idea and no god damn clue they need to throw away the toolbox and give the job to someone who figures shit out and fixes things rather then make everything ten times worse lol Respect bro From Australia

tulsie from the usa great job

I just wondering about the key programing did ur frend send u a file to program the keys not sure how u done it great stuff by the way

where do you get the schematic over the boards ?

Good job well done

Hi ive got tourneo 2017 same as focus blowing f33 fuse body control no start ...no communication with bcm how do i check bcm issue

Great Job! I have an airbag fault on my BMW E60, can I book my car in with you to repair it??

Where can i get the electrical drawings?

Hi luis, out of curiosity how do you charge for jobs like this? By the hour? I always struggle to know how to appropriately charge for diag work

You did well, how long was the diagnostic time?

Awesome 👍

Hello, good morning, I am a follower of your channel and I am contacting you, to be able to comment on the following situation that occurs in my vehicle, Ford mondeo mk2 2.5 v6, one morning the battery was discharged, without knowing how to change the battery, when month or so, the car stopped in full operation, it was as if the electricity had died, stop, giving it and giving it until it started, again as if the battery was without charge, it was only a month old, I changed the alternator regulator , and well, I bought it, it charges over 14.5V, and I considered the fault finished, one day cleaning the interior, I left the radio on, while I cleaned, and nothing a few minutes later, the voltage began to drop, less to less, until the battery was discharged at that moment, I was surprised because that had never happened to him, I did another test, with the battery charged again, I gave the contact, after a short time, equal to less to less , that in a moment the battery goes away, I recharge it, install it, and leave it and connected approximately 2 months, until I realized that the red light of the alarm did not blink, I checked it and discharged, that did not happen in the past either, it carried out the current leakage test with the multimeter, because I told myself that this would have to be a current leak, it is the logical thing to think, and what was my surprise, that the value it gave is 0.02 amps, with the battery just charged, so there is no current leak, I have also performed the voltage drop test and it gives 000v both positive and negative, and then what happens to it? I don't even know what else to do, regarding what I am explaining to you, I await your prompt clarification, please, greetings.

It was an interesting video Luis. I know that you like to dig deep into repairs but sometimes this can turn into frustration. Most self employed mechanics have been there. I have been there with a Kia Sportage and a Nissan Navara. In the end I got sick of looking at them. It is a source of learning, these repairs, but they are also the ones that make you question yourself " why did I accept "? and give you some extra grey hairs.

Honestly you are a great school

That took a bit of sorting, hope his bill wasn’t more than the car is worth🤣 and yes I did make it all the way through 😬 Don’t you think it’s about time you gave up on that worn out protective cover on your meter🤔 have you thought about sticking a mobile phone screen protector on instead as they’re not expensive😉

Can you code abs or fuel pump with vcm2 ford

Hi whats best way to check the circuit

Boss I have question who to find ic pinout diagram

the (algo) Rythm is gonna get you....

How do you deal with having to buy and return several modules and repair other people's mess

Chapeau,

Just seen this video mate , i have had this stuff presented to me and in the trade it gets booted. often its taxi's

So bad idea to use parallel wire by that other "mechanic". 14:15 send it back, this is mess

talk about a dogs dinner, some people shouldn't be allowed to touch cars..

can you tell me how many hours of labour did you put in to this car?

Where do you get wiring diagram please

165.553 miles on the clock?! The steering wheel is in "like new" shape...who's driving this car?

👏👏👏

Customers think if they lie it would only cost the price of a bulb,wup it up em they deserve all they get and more.

well you stuck at it .. and it got done .. .. another one bites the dust.

Well I watched the video to the end,You could of ended this issue faster by trying another BCM from a donor car,and check if the fault is gone,like you did with the one that have the wrong number,also why you searched for the exact number while the guy at the dealer gave you the new part number for newer version that have a better circuit or a better software,If I were you I would not use the same part number.
