Adaptive Headlight Warning on Dash

Recommended Posts

Had this warning come up on my dash about 4 times asking to check Adaptive Headlight ( see manual ) well checked manual and does not say much about any faults, car was at dealers for new wheels to be fitted so asked them to check it over, they said nothing showed up on diagonostic machine but it still happening ? Anyone else had this?.

Looks like one of the adaptive headlamps has gone into default get you home mode.

Turn everything off, disconnect the battery for 10mins and connect it back up.

Cures most things

I've had it a couple of times. I just ignored it, switched the ignition off and back on again and all was well. Remember the mantra: "It's not supposed to work properly, it's computer-controlled."

I have this problem with my Edge, has anyone found the cause, and the cure of the problem ?

 

Mine has been back to the dealers 3 times, and they are stumped !

They have contacted Ford direct, who say No-one else has had this problem, But after chatting to the dealer about the issue, they now say a Directors  also has the same problem ( Cant believe a Director has never reported the problem on his company car )

I had it occur on my previous Focus ST twice.
Dealership fitted a new headlamp and programmed it in.
I believe it was a faulty module that was part of the lamp unit.

Sent from my SM-G965F (S9+)

There will be diagnostic Trouble Codes (DTCs) stored in the adaptive headlight module which will tell the tech exactly what is wrong and their Service guide will tell them how to test, confirm the issue and what needs replacing.

Adaptive headlights take inputs primarily from the windscreen camera and steering wheel position (as well as lighting switches, etc). It will also monitor what its told the headlamp until and if that doesn't report back what it has been told to do, it too will raise a DTC. The logged DTC(s) will tell you which of these the module is not happy about.

Take it to another dealer that knows what they are doing!

When it happens, the only way to reset it, is by turning the ignition off and on, and this is clearing the warning, AND deleting any fault codes.

They have asked for me to return to the dealers with the Warning still displayed, so they can see it for their self, but unfortunatly, its only happens in the morning going to work, and they are not open that early, or in the evenings, and they are not open that late.

Ignition cycles and/or a period of time where the fault isn't still present (i.e. an intermittent sensor) will clear the 'Active' faults on some systems (the ones that show up errors on your dash and in the case of an engine, put it into limp home mode), but the fault will still be logged in the ECU as 'Freeze Frame' data and that can only be cleared by resetting the codes in the ECU via a diagnostic tool. There are some faults that clear after a number of ignition cycles without the fault re-occurring, but there aren't many that have that strategy and I would certainly not expect a system that has roadworthy or safety legislation doing that. I've never seen that and I've been involved in vehicle diagnostics (car, trucks and construction) for 15+ years.

If they want to see it, I suggest taking a photo of the dash when the fault pops up. that way you can just show it happens and then hand it over to them. The chances of you turning up with the fault still active sounds fairly remote! I would suggest getting yourself a cheap ()£5-£10) Wifi ODBII reader and FORScan (Free), then post any fault codes on here and we'll try and help you out.

Already taken a photo, and shown them (Look in my earlier messgaes )

 

If it still carries on after this round of inspections/ equiment changes ( Think they are going to replace both the headlamps ) will ask them for advice / help on the OBDII, see if the fault can be recorded that way, as it's getting silly now !!!

 

Thanks for the help

Good morning all,

Has this issue been resolved on your recent trips to the dealer with swapping headlights?

My Edge has just popped up with the same warning message this morning. No auto main beam or manual main beam with the stalk. No adapting of the lights either. 

Just spoken to my dealer to arrange a booking. 

Thanks

Owen

Had this happen over 10 times now, really annoying as most of my journey to and from work are along unlit B-roads, and the get me home beams are awful as sometimes they point down so low I can't see far at all, other times it's no so bad. And you can no longer use your high-beams to flash. What I don't understand is that they appear to be working absolutely fine until the message appears.

Some days I can get through the day fine, others, as soon as I pull off my drive or 20 mins into a journey. No rhyme or reason.

I've connected an ELM ODBII adapter and read my ECU via Torque(android app) and it shows no errors, this was whilst the check adaptive headlights message was showing and my engine running. I've taken photos of the message being displayed on my dash, I am due my 18K service shortly and will mention this when I book. But don't fancy playing dealer-ping-pong!

Well been to the dealer with lots of photo evidence during my 18K service, they cleared a low battery error from the ECU and told me the issue was now fixed. Following morning happened again! Booked in again towards the end of the month.. Cannot believe nothing regarding the issue is not stored in the ECU for interrogation, clearly a fault or condition triggers the display message?!?

I'll let you know how I get on....
