Hi hope this reaches the right place, 

I'm having some issues with my ford focus 2011. Both Headlights work but won't adjust up or down. New headlights and switch not sorted the issue. Another point to note is there is an intermittent fault with the right indicator cutting out which may or may not be related? There was water in the front right headlight male and female connectors both have signs of corrosion. Not obvious sign of water travelling to bcm as connectors that end were fine, however, bcm fuse had popped but since has been fine. Anyone have any idea on possible cause or fix would be greatly appreciated tia! 

Xenon's or halogens?

There is a fuse for headlight adjustment if halogens.

Front and rear or is it just the front ?

Check these fuses:

Thank you for your replies, they are halogen. All the fuses have been checked and replaced all seem okay. The traction light is on the dashboard intermittently aswell only just starting occurring today not sure if it's related. No faults showing on the snap on either as mechanic plugged it in friday. Indicator works at the rear. Funny as it sounds if you give the car a thump on the mirror Indicator it fixes the fault on the front Indicator it's very strange!

Ah !!

There's your first problem. 'Snap-On' are good and very expensive but unfortunately often do not read all of the Ford specific DTC's. To ensure you get all the codes (other than going to a Ford dealer) you need to use the software FORScan and the connecting cable 'vLinker FS'

Not so strange on a 2011 Focus. There is a known issue with dry/cracked solder joints on the back of the instrument cluster that causes all kinds of random faults. The standard test to check for this is to thump the top of the dashboard just above the IC.

There are many companies online that offer a repair and refurbishment of the IC for about £85 just do a quick search with Google or look on eBay. @rd457 also offers a repair service on these with a quick turnaround.

Thank you for the links very helpful, yes agreed about snap on. He said  I would need an auto electrician as snap on wouldn't pick up anything of use. I will download that programme and buy the adapter. Oh thats interesting about the ic that sounds like that could well be the fault. As the car does cut out at times and maintaining revs especially in reverse aswell but that has been ongoing a long time. Would the instrument cluster cause the headlight adjustment to not work aswell?

Yes/No/Maybe 🤣

The list of very odd faults that has been caused by the broken solder joints on the instrument cluster is so wide and varied that just about anything is possible. I would recommend getting the IC professionally refurbished for the sake of £85 and I'm sure it will sort out many of your problems.

If you use FORScan before you get the IC refurbished I expect you will find a lot of DTC's that begin 'U......' which often points at a communication error with the IC.

Cars hey 😂, fords fantastic when they work but when they go wrong they know how to do it proper 😂. Yes I will do that first, a friend has offered to come around with a autel scanner never heard of, could that potentially show me faults the snap on wouldn't? Or should I just wait for the adapter ans use FORscan

with a autel scanner

Nice bit of kit, even used one once, but it is the case that the only two devices/systems known to read all of the Ford DTC's is obviously the 'Ford main dealers diagnostic equipment' and the other is 'FORScan'.

Ford vehicles have two Canbus systems. A High Speed and a Medium speed. Many generic scan tools will only read the high speed and some of the codes on the medium speed canbus.

My cluster repair links, if you're considering my service: cheap one, standard one, premium one

Geez, so to summarise...

• Headlight leveling is not working for either unit, though illumination is
• Both headlight units were replaced along with "switches" and this made no difference to leveling feature
• Old right hand headlight unit had water in it, male and female parts of connector corroded [Both sides or just right? Is/are the wiring loom part(s) of the connector(s) still corroded after headlight replacement?]
• Intermittently the 'right indicator' is 'cutting out', thumping the indicator on the right hand mirror fixes this
• BCM fuse was found to be blown, was replaced, all fuses checked and now good
• Intermittently traction control light is illuminating, as of today
• Car cuts out at times, also something about 'maintaining revs, especially in reverse', which is a long term problem
• Has halogen bulbs, unknown whether has 'adaptive headlight' system

The note about the right indicator cutting out isn't very clear, there are four lights for each direction, the one in the instrument cluster, the one that's part of the headlight unit, the one on the mirror (side light), and the one that's part of the rear light (tail light) unit. You've said that the rear light works, but which of the rest are not working? Your mention of bashing the mirror indicator makes that one work, so is it just that one that's faulty?

I think the fact that bashing the mirror indicator fixes it is a huge clue that this problem (assuming its only the side light that's not working) lies with the wiring within the mirror.

The indicator system is pretty simple. The indicator part of the stalk is connected directly to the GEM/BCM, and upon selecting right/left the GEM/BCM does two things in response, it sends a message to the instrument cluster (IC) via CAN bus to get the IC to flash the light and emit the ticking noise, and it provides power to the three simple bulb power circuits (front, rear, side) to illuminate them.

Headlight leveling, with halogen bulbs and without (?) adaptive headlights (lights move side to side with steering), also appears to be fairly simple circuitry. Each leveling motor has three wires (1) power via fuse F124 or F125 (left/right), which appears to be shared with the parking lights, (2) a ground wire which in both cases goes to ground point G20 via an intermediate connector C111, and (3) a connection to the leveling control, via a join to a single wire within C111. The leveling control is a potentiometer, also with three wires, (1) power via fuse F115, (2) a ground connection to ground point G20, and (3) the potentiometer connection to the levelers, which splits to each of them within C111.

Is this control part of the "switch" component you said was replaced? With both leveling units not working, we should look for something they share... If the level control was replaced, and you say all fuses are good, then that would leave the power and ground wires for the control, the shared connection from the control to the levelers, which notably splits into two within C111, and the ground connection to G20 from the levelers from where their ground wires get spliced together (somewhere between G20 and C111). It is interesting that you said that the headlight unit wiring plug/socket was corroded, did you mean for both headlight units, and is the one side of each plug still corroded after headlight replacement? Could this corrosion really be causing identical failure of leveling only on both units? I'm a little sceptical on that... This all really needs to be investigated with a multimeter.

(I'm taking these component reference numbers from an old leaked 2008 Focus wiring document).

I'm also not quite clear on the cutting out and maintaining revs comment. There could be any number of things causing this type of problem, it could be a wiring issue, as seems to be the case with the above, it could be something mechanically wrong with the engine, or a sensor issue, or I suppose it's possible that the common cracked solder joint issue with the cluster (that I repair) could somehow have something to do with it in terms of how it can interfere with CAN bus communication...

Unexpected warning lights coming up on the instrument cluster is one common symptom of the cracked solder joint issue. So maybe the traction control light is a symptom of this.

Being a Mk2.5 (Mk2 with facelift) Focus, this is the type of cluster I repair by far the most for the cracked solder joint issue. It's very likely yours has cracked joints, though there's no certainty that it's responsible for any symptoms. (My own was cracked but symptomless).

Given the simple circuitry of the leveling mechanism, I'm sceptical.

Hi, thank you for your comprehensive reply @rd457! I should clarify my car is MK3 as far as im aware its an 61 plate. Sorry I've not been clear, the indicator is only the front right. All other indicator work as should. All fog, parking,high beam lights also work, however the parking light had actually blown interestingly enough. Yes if I bash the above the front light, dash and below the mirror ring. 

Regarding headlights from what I can tell it doesn't have an adaptive. As suggested by @unofix  I have ordered the vlinker and downloaded FORscan on the laptop. Yes it seems to point towards a wiring issue as you say I've brought an Haynes manual so I'll see if I can see the wiring on there. My friend come over with an autel again as advised it didn't register any faults. Would an wiring issue not show up on these plug ins? Just the switch face was replaced let me link the part https://www.ebay.co.uk/itm/362433048161?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=FSbuHVuwSru&sssrc=4429486&ssuid=tC-mvOxBQLq&var=&widget_ver=artemis&media=COPY. Headlights replaced too. Left one no damage. BCM no damage, but there is some minor corrosion on the right loom connector to the headlight. (May not be the right name?)When I plug in tomorrow I'll upload a picture of damage. This the problem it's very unusual for them both to go and not be resolved by new headlights which like you say suggests wiring. A few garages have said it most likely needs a new BCM but I'm just very sceptical that's the case as surely there would be faults like unable to open the key use wipers etc.... its just a very expensive "could be the issue". Yes i have an multimeter but to be honest I'm not quite sure how to use it!! I will plug it in tomorrow and see what flags if anything!

Battery DTC  of some sort? 

Park brakes 

Oxygen sensor. I'm sure this has been caused by an previous oil leak.

Heated window & Ignition relay 

 

Do these faults point to anything significant? Thanks again.
