Hi
This car came to me from another garage, no crank, no start with the immobilizer light flashing and a message on the dash saying engine systems fault...
When scanning, no communication with the PCM...
Follow me on this video to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!
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 👍
So far so good...
Thank you for watching and for your comment!
I have done about 30 of them over the last couple of years. The solder joints literally crack around the plug. The other common one is the wire that goes from the engine ECU to the bonet fuse box, that fires the efi relay, it corrodes right on the bend in the big T junction where the harness is all taped together below those 2 ground points.
@@threepotMR2 Yeah. It amazes me how many different cars we get in and the wire that seems to corrode the most is the wire the ECU switches to GND to switch the EC relay on. Doesn't matter what make.
@@timmehlittleloud2251 Maybe its to do with electrolysis as it's a continuously loaded wire?? Or maybe someone in the factory is paid to stab a hole in the insulation just so the cars last about 7 years in the British weather :D
Hi I have exactly this problem. AA can’t find the issue. All grounds have been replaced. When you say cluster you mean the dash display cluster? How can I find out if this is the problem? Thanks
Nothing more satisfying than finding that broken wire. Great find and repair . Thanks for the vid
Yes it was...
Thank you for watching and for your comment!
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.
That's great!

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!

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
Hole you get back and running...
Clusters on these are also known to fail at the solder points... and need re-solder...
For most likely will not do that, and will just replace the entire cluster...
Thank you for watching and for your comment!
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.

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. 🙏

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!

And when erasing the faults, the cluster shows no faults..
But I think I know what you mean... I should have entered into the IPC and show that there was no faults...
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
Possibly...

Hopefully...🤞

@@LMAutoRepairs hi nr fon ? Pleazz
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.
Absolutely...

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.

Had cluster checked and ecu and key now checking terminals bcm I had new starter all ok so must be wiring fault reads d900 e510 on cluster
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.
Hi
It is in some cars... But to be honest so is the IDS...
Overall is a great tool...
Thank you for watching and for your comment, appreciated!
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)
I've just swapped LS 2 liter. And all connectors in right place and tight..but still same problem engine system fault .no communication .anti theft alarm .
Another interesting video, Luis.
Thanks!

What happens on your dashboard the temperature gauge soon and see start is goes halfway what causes that
thanks for video, great job.
Thank you for watching and for your comment!
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.
Hello have you fix your car I have the same problem which you explained
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
Which computer are you referring to?
I have the windscreen been broken and water come through, later on the horn won’t stop, the same day they fit the new windscreen car didn’t work when they connect the computer it’s happen same you have problems every where they check the BCM it’s nothing with it
Do you this it’s the cluster
If not can you help with some one in Livetpool he can help me thanks
Good work.
Thanks!

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.🍻
Check power and grounds to the PCM...
If ok, check CAN lines...
👍👍👍
Thanks same problem or ford focus 1.6 dtci 2005 year.No brocken wire bat corosion probmem.thanks
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
Hi
That's a good point about the scanners...
There is cheaper ones out there that can be really good for DIYers...

thank You for that, i got same problem with smax 1.8 125km, do you know where i can find information, which pins are for plus and minus in my case, or they are just the same?thank

HIE sir i have a 2008 ford fiesta TDCI duratorq 1.6 , it doesnt start it cranks till the battery runs flat ,this all started when they poured petrol instead of diesel at a gas station , i had the whole engine checked and flashed but never came right when i use EASY start the car starts and idles properly ,driving a few K's it flashes a engine faulty message , can you kindly help me on this i would really appreciate your help
I'm sitting with focus now it shows no faults but don't crank. We checked all fuses and realays had to replace some still not cranking.
You need start to check the starter motor circuit...
👍👍👍
We are buzy with that thks
When you bridge the starter at relay it cranks and it looks if the inj don't response
If there is an issue affecting the starting circuit, it might be that it is also affecting the injection... carry on checking further back...

Scan the car first... you can have this symptoms, caused by a different problem... if that makes sense...😉
@@pedromesquita6309
I understand that... but without scanning, you will be chasing ghosts... is a guess game...
Plus, as I said, you can have the same symptoms caused by a different root cause.. the engine fault message, is a generic message...
Find someone to scan it for you, and go from there...
Or check what I have done on this video, you might be lucky that actually is the exact same problem... as you believe it is...👍
