@Beau Garrett instablaster ;)

[@beaugarrett6751]

@Hendrix Roger thanks so much for your reply. I found the site thru google and I'm in the hacking process atm. Seems to take quite some time so I will reply here later with my results.

[@Brenjdonn]

This guy is a genius, in some ford garages this problem could go on for months!

[@8power0]

NOW THAT'S WHAT I CALL USING A WIRE DIAGRAM TO THE FULLEST ,,,, GREAT JOB !!!!!!!!!!!

[@alanriddell2277]

Love the fact your videos are real time workshop floor videos making the best use of a given time to arrive at a conclusion. Thanks and keep them coming.

[@SYDiagnostics]

Thanks for the comments and support

[@rcmc88]

It is a shame more Techs and mechanics aren't as knowlegable and thourough as yourself. Keep the videos coming

[@SYDiagnostics]

Thanks for the comment, it makes it all worth while

[@richardthomas31]

I was very sceptical about this fix, the stop/start hadn't been working for quite a while which I thought was due to only doing short journeys and the battery maybe not being fully charged, however, I gave it a try and it worked, great, simple and not to mention a free tip. Thanks

[@SYDiagnostics]

Have you commented on the right video?

[@miguelferreira1051]

Your videos are excellent... Teach like a true teacher... Congratulations...

[@SYDiagnostics]

Thank you! 😃

[@davidsinclair5004]

Really methodical video in fault tracing, good job. It makes diagnostics so much more effective when having access to good wiring diagrams, topology, and locations. I think we struggle here in the uk so much more on available data as opposed to our friends across the pond ( as keith defazio would say). Thats where i lose so much time is behind a computer screen building a wiring layout, autodata then on to alldata then to haynes pro, it just gets so time consuming as well as information is not cheap. Anyway really enjoyed your thought process.

[@SYDiagnostics]

Thanks for the comments, yes, I feel nowadays its only dealer diagrams will get you the win

[@harhar4607]

Clear, concise & truly educational.

[@SYDiagnostics]

thanks for the feedback.

[@stevehayes7921]

Brilliant as always, so informative great to watch..

[@chrispoole4413]

Another great video SYD. Methodical process to investigate and diagnose. No guessing with the parts cannon! Learning all the time.

[@SYDiagnostics]

you're welcome, thanks for the support

[@jonstringer41]

Great video as always, excellent methodical approach with the help of first class diagrams and information system makes the process so much easier. I wish I had access to that level of information. Keep up the good work Steve 👍🏻

[@SYDiagnostics]

Forscan is free, the diagrams can be accessed for an hourly fee or through subscription to all data. The Process is just being methodical and understanding what is going on, info helps but isnt everything. Thanks for watching and for your valued comment. .

[@JBTaylor86]

Top work Steve, your logical process is 2nd to none. 🤜🏻🤛🏻

[@SYDiagnostics]

Cheers John

[@AbbottAutomotive]

Fantastic all round work Steve. Congratulations on your 5K subs, here's to the next 5K, and very well deserved 👍

[@SYDiagnostics]

Cheers Dave and thanks for the continued support. Lets hope the targets are achieved !!

[@roadsidediagnostics1017]

Another great video. Really valuable studying the wiring diagram and not jumping straight in and stripping out panels and modules. Had to be a common factor 👍

[@paulchester656]

Find your video’s really informative and interesting. Looking forward to your next one.

[@SYDiagnostics]

Thanks for the comments

[@sandyande]

Brilliant diagnostic Steve cheers sandy

[@SYDiagnostics]

[@karmagreenock7622]

Your videos are brilliant keep up the good work

[@SYDiagnostics]

Glad you like them!

[@romanosautomotive]

Great find SY! I just got FORScan set up and I'm hoping to make as good use of it as you do!

[@SYDiagnostics]

Have fun!

[@steveeastman481]

Yet another well made informative video.....thank you

[@Casavult]

Great video. Love this stuff.

[@SYDiagnostics]

thanks for the comments and support

[@willcarling343]

Fab video. Have you got any experience of TCM module errors. My 1.5 focus auto won't start and it seems to be a TCM communication loss. TCM error when trying to read it with forscan. Also can't get it out of park. Any help much appreciated. Thanks.

[@benjaminlevi7792]

All your videos are very useful thanks

[@SYDiagnostics]

Glad to hear that

[@chrismangan3250]

Once again logical evidence based diagnostics and great product knowledge. Excellent. You mentioned making a breakout lead, which video is that in please?

[@SYDiagnostics]

its in my transit can bus video, i dont show any details of it as im looking to get some made up

[@SYDiagnostics]

thanks too for the comments and support

[@sparkyindahouse]

Great video...was the wiring diagram on FDRS and is this only available to profesionals?

[@SYDiagnostics]

wiring diagram from ford etis which is subscription based

[@carlosf.2134]

Excellent video! Thank you very much for your hard work. I’ve got the same problem and your video has helped me to understand what may be wrong. How much would it cost now days to fix something like this? I just don’t want to get ripped off. Thank you

[@SYDiagnostics]

Diagnosis costs are a tough one. A decent garage would discuss it with you and outline an initial time scale they'd want to carry out any necessary checks etc, then any extra time will need to be negotiated. Fixing the issue is the easy part I'm afraid, finding the issue is the skill

[@MePeterNicholls]

The other week my start stop stopped working, SOS suddenly pinged inactive, and the parking sensors too! Restart all gone. Weird?

[@gusmacdonald5370]

great find mate. thanks for sharing

[@SYDiagnostics]

you're welcome, thanks for watching

[@ingejeppesen1358]

"Just a bendt pin" How many would have gone highwire stripping down miles with electric tape first. Nice job. Well done. Have a question, how much time do you get to troubleshoot something like this? Is it like work on it till it is fixed, or do you go between cars?

[@SYDiagnostics]

this was a pretty quick fix, so i was on it until diagnosed and fixed. Usually i'm given and initial 1hr and then im onto other cars

[@yvannm7762]

Hi ! i have the same problem, but it was after putting my new battery, it can be the same fix or not ? It was working with my old battery

[@newcybrown6352]

Great video . All that from a bent pin eh . Modern cars ...computers on wheels .

[@JoesAutoElectric]

Great job on this. Do you know what happened with the history of this car? Was someone in there for some reason?

[@SYDiagnostics]

From what i can gather its done this from new, but has been very intermittent, to the point it become daily. No previous work has been carried out according to its history. Thanks for watching

[@leso204]

Has this area got a reputation for water ingress , im losing cam hi/lo signal strength error' sometimes forscan will not read DTC's on any module but engine starts stops with all dash working ???

[@SYDiagnostics]

Im not aware of any known water leaks in this area

[@fliper1202]

Professional, at the highest level. Keep it up! I have focus 2012 and forscan, and playing with it a little. What is that softver that you use for network test, does it require special hardware or can it work with the same device used by forscan (Vgate vLinker fs)?

[@SYDiagnostics]

that would be FDRS the dealer tool

[@CARRJ142]

Another great video.

[@marenghi123]

Great video. Does the mk3 focus have the same plug in the same place ?

[@SYDiagnostics]

Its a different lay out on the Mk3. There are plugs in that area, but without looking at a diagram and knowing your concerns, it'd be hard to say

[@JamesPond-cd3tp]

I have a Ford Smax 2.2 tdci 2008, the instument cluster intermittently seems the loose comms and the radio flickers on and off. I've had it resoldered on the main pcb connector but it's still doing the same thing. Going back some time I had the alarm sounder disconnected as it had water ingress and caused window wipers to go on and off on their own. Would the alarm sounder disconnection cause issues with the cluster? Any ideas? Also where are you based, I'm a DIYer but this seems beyond my skill set..

[@SYDiagnostics]

I've known the harness rub down the side of the centre console near the radio etc. It's clipped to the metal frame and the can wires short

[@omarsawaftah325]

Where did you get this wiring diagram?!?

[@SYDiagnostics]

its the genuine ford diagram from ETIS

[@yankelecom]

Hi I also got a Ford focus MK4 with several electronic issues (from time to time). Front camera errors, batterij voltage error, also that pre-collision warning and then it goes into limpmode, sometime the addaptive suspension gets extremely firm settings while driving (car off/on then it's back to factory settings). The start/stop only works 1 day/year and that is why the garage recommends me to change the battery since it's capacity is below a threshold and why the start/stop function is not working. But I'm not convinced why that is a reason why the other errors are occuring. I also have troubles with main the drivers window not being shut automatically because it believes that halfway up there is an obstruction and it goes back down. Then they recommended me to disconnect the battery for >20min but that never worked to relearn the stop position. Yet I believe by disconnecting the battery, the sensor that is reading the voltage may be de-calibrated. Still I don't believe that is the only main issue even after having all the latest updates, it's still unsuccesful. What would you recommend as steps in a diagnose? I have the forscan app on a mobile phone with a bluetooth OBD2 connector, so I could read the errors myself, i believe.

[@MePeterNicholls]

Ooo. My vignale doesn’t tell me washer fluid low. Never has 😮 I need to ask about tgst

[@MrAaronD1]

Great video mate 👍🏼

[@SYDiagnostics]

hi i need wiring diagram module communication network of a ford ranger 2019 2.2 l diesel....... can you help me with that ... please bro ...

[@gigipurcescu]

Hei looking to buy a new ford, how many of these have you seen?

[@SYDiagnostics]

i'll be totally honest and say this is the first and only can issue on a mk4 focus ive seen

[@gigipurcescu]

@@SYDiagnostics thank you for the reply, what about other issues that came to your shop

[@SYDiagnostics]

@@gigipurcescu don't really see many issues on the mk4 focus, window motor issues, sync3 screen issues, oxygen sensor faults.... All covered under warranty

[@hansvarca3616]

Nice mate 👍

[@SYDiagnostics]
