Great video, have a 2010 focus and had a problem where my auxiliary input & Bluetooth just stopped working. Ran the test and came up with DTC #00 None like yours and the Auxiliary appears to be working again maybe just needed a refresh or something... cheers

cant wait to try this out! handy tip, thanks!

sorry about the delay, still trying to find some free time

@TGmick i don't think you can intentionally change things, i know i accidentally changed things when driving the car in diagnostic mode managed to reset my mileage once which was genuinely amazing, but the next time i fired the car up it was back. that happened because i was running the car in diagnostics mode on engine temperature and i was stuck on ice with some serious wheel spin uphill. if you can find a way of repeating that see if you could save it? new way of clocking cars perhaps?

@cmagennis927 yes keep pushing the set-reset button to cycle thru all the tests

@acid987 no equipment or software required, just follow the steps in the video :)

@elboydo06 haha awesome. I saw 'chimer module On 750hz 50%'. Sounds like you could change though, maybe by flicking the menu up or down? 50% volume? When my focus went in for its recent service the warning sounds seemed louder, dont know if it was just me or Ringways run this test as I guess they would and changed it

took it down to the dealership and they wanted 70 quid to check it, so we said we'd bring it back when it dies then they can fix it on warranty :D, its been having a few rough starts tho recently :\

I used to get a clinking noise once or twice when driving my focus, i'd recommend posting about this in some owners clubs/forums see if anyone else has any better advice?

Cool, never thought i could do that to my focus, Can you change the level of volume for the warning sounds/indicator sound? and what else could you change for the car? Thanks. Going to try this mode out tomorrow, just thought i'd ask you what i could change before I messed something up by some random codes lol

Hi my aunt has a 09 SMax 2L TDCI Zetec and there was a problem with the boot lid and parking sensors, I tried dong this diagnostic test on the car but after the gauge sweep it never went on to do the LED test? Do you have to press a button so it can do the LED test? Thnx

Good Job & Thank you

Cheers for that buddy, I take it you were scrolling through the test stages yourself b pressing the button again?

recently noticed when driving the car in diagnostics mode that when the fuel warning light came on the light flashed constantly and the low fuel tone/noise kept repeating till i re-started the car :/

the s-max seems to have recently chewed apart its own air-box somehow :S, could be linked with this problem some time ago, just thought i'd mention it ;)

The negative cable should connect to the chassis (ground)

Please, how to manage self-diagnostics on the Ford C-Max r.v.2008 1,8tdi It would help me a lot There is a list of error code ford? thank you very much Paul J.

does it happen at 12mph? Mine does it too - ABS self check is what I've read too (happens to my 59 plate 1.6 ztec TDCI)

Nice! Is there a way to get the mileage data from Ford Focus?

gracias por la información

How do you do it on a Titanium S-Max with no key to ignition? Cheers

Hi bro...how to do that with my focus st 2009 if it has to start a button...not with key!!! Help Please. Thanks

i have tried on my smax 2009 zetec auto but it just end up on TEST word but it doesnt check the gauges

yeah, theres quite alot if you lack patience, i wouldn't reccomend you do this, first few times i did it, i passed the DTC code thing haha then had to keep going thru them till i got back to it

Parabéns obrigado pela ajuda information

I have a engine light on doing this will it give the code

Did you check what was the problem on the S-max ?

Don't suppose you know how to attach jumper cables to the smax battery to use it to jump start another car? Obviously the positive point is accessible but not the negative....

the only real noticeable changes is the facelift to be honest, ford did have a big change of all their engines in 2008, think it added a handful of horsepower but nothing amazing. i afforded my 09 1.6 zetec s on finance with a part time tesco wage ;P

Have you found out what C41668 was ? I have the same message appearing on my S max

Thank you

Hi mate need your help ... Just bought a 60 plate ford focus zetec 1.6 and every time I start up the car and travel bout 100 yards I here a small clunking noise .. I took it back to the dealer and was told this noise was a self test on the a.b.s ..... Is this right?? It only makes this sound once when I'm out and about ... But every time when I start the car..

@kilito12 sorry absolutely no idea how to do this with keyless tech!

ill get on it asap : ]

@elboydo06 lol but what can you change? :P

you get the mileage stats in KMH, if your like me and used to using miles i found it irritating lol

@TGmick i decided against messing if i'm honest with you haha for exactly the same reason ;)

I would be much more worried about why they put your steering wheel on the wrong side of the car.

Thank you
