Driver assist issues

Recommended Posts

So we just bought a 2012 focus titanium x with the driver assist package. In fact it has almost every option as far as I can tell apart from stop start. Can you add stop start?

Anyway on the way home I tried everything out and it all seemed to work fine. I noticed that the lane assist would only pick up 1 of the white lines most of the time and it only seemed to pick up 1 traffic sign at a time but thought maybe thats just how it is.

The next day though the  lane assist will not turn on. You press the button on the end of the stalk, the dotted lines appear on the display and then they disappear. In addition to that it now picks up no traffic signs at all. Im guessing the problem is related as they share the same forward facing camera. There are no warnings or messages and the screen is clean. I got a message saying the screen was dirty on the way home when we picked it up but once the screen was cleaned the message was gone.

 

Does anyone have any ideas what could be up with it? I am a mechanic and have a snap on diagnostics machine but not even tried plugging it in yet. I am guessing there is specialised software for the driver assists but I could be wrong. Any help would be much appreciated.

Thanks, Dan

Anyone? There must be some guru's on here...

I read about forscan. Would that show any issues with the driver assists?

Forscan is an ongoing project, being added to all the time. It is a Wiki style collaboration of enthusiasts.

I have not heard of driver assist features being included yet, a visit to the download page which lists the main mods & additions might give the latest info. Or just try it. It will probably be useful anyway.

If you have a Windows laptop, you can get Forscan for £15. bit more for wireless iOS or android.

For Stop-Start, I am not sure if it needs a beefed up alternator or other bits. Possibly Focccus software can do it. This uses the same adapter (ELM327) as Forscan.

Forscan works best on a Windows laptop, with a USB ELM. The Tunnelrat one (below) has been reported to work well by several people. Forscan is also available for iOS & Android for some tablets & phones.

For a USB ELM327 adapter, see
http://www.spanglefish.com/TunnelratElectronics/index.asp?pageid

Wireless ELMs are also available (bluetooth & WiFi), but are often not as reliable as the wired ones. Also they are rare in the "modified" form which is needed to access the 2nd Ford bus system. This 2nd bus is the MS-CAN bus, and links all the car interior electronics like door modules, and the BCM (aka GEM). But a standard ELM will still work with all the Underbonnet Modules (PCM, ABS etc) and with the IC (Instrument Cluster).

For an bluetooth wireless ELM, which one user at least says works with Forscan, see the KW902: http://www.ebay.co.uk/itm/ELM327-KW902-Bluetooth-Scaner-OBD-Link-OBD2-Diagnose-Interface-Tester-white-UK-/281631334205

The Forscan programme is free (in Windows format) and you can get it from:
http://forscan.org/download.html

Sorry, but I am no expert on the workings of the driver assist similar facilities!

You'll need a different starter and battery for stop start. I wouldn't try adding it to a car that doesn't come with it from the factory.

Forscan definitely the best thing to try and diagnose a fault outside of IDS.

thanks for the reply. much appreciated. I will look into that. I have ordered an ELM327 adaptor that I can use with my laptop/tablet/phone and will give forscan a go and see if I can see anything. I will also have a look into the  focccus software and see what thats all about.

take it back to dealer where you got it, it should still have warranty b4 you have a go at it otherwise you may invalidate the warranty

it was a small dealer and having some experience in that area form the past i know dealing with them could be a nightmare. They are also a few hours away as at the time there were only 2 white 2.0 titanium x's for sale in the country and this was the best one.

 

pluging into diagnostics wont validate any warranty anyway. They wouldn't even know. 

 

I will diagnose it and go from there. the car has a 3rd party warranty but I doubt a camera would be covered if it is that.

I understand plugging in diag m/c wont invalidate anything but if you start messing with things it'll be there excuse not to pay out

it may be worth asking the 3rd party people though

yea i wont be messing around with anything. Just diagnose the problem and then i can see if there is any cover from either the seller or the 3rd party insurance.

My completely amateur guess. Condensation in the shroud/cover obscuring the camera/sensor lens?

dirty screen then playing up next day would have me guessing that.

Just a thought but at what speed are you switching the system on? Below 40mph it doesn't work. Traffic sign recognition is accessed via a menu using the buttons on the left hand side of the steering wheel. 8ad8a768f131ec475a91c0aa4abe2741.jpg

You sure your car doesn't have stop start ? I've got a 2012 Titanium and mine does 62 plate. 

Stop start doesn't always work, but you can tell if you got it by the button on the front console in front of the gear stick. Next to the front and rear window demist button.

Have you got an original Ford winscreen in there? Do you know if that's ever been replaced if it is a Ford one?

A non OE glass windscreen can cause any number of issues if they've not put the right stuff in there in the first place. I read somewhere else about Ford genuine having a special coating for the sensors, and that non-OE glass doesn't have this causing issues.

Sounds like you need to have your Lane Guidance and Traffic Sign camera re calibrated. I've just had a second new OE windscreen on mine and Autoglass now have the ability to do this otherwise it's back to Ford to get them to do it.

it does have signs of the window being changed...

also noticed that the auto high beam no longer works... I used it the first night we got it and it was going a bit mental turning on when cars were coming the other way but since then it has never worked.

Does anyone know if the cameras and stuff are part of the screen or separate? 

pretty sure no stop start. Will have a look and see if there is a button. Its the other halfs car and I dont drive it much.

If you want to check what specs your car came with, then use Ford ETis. It will list everything your car came with when it was built. Stop start will be listed as Starter - Stop/Start System

https://www.etis.ford.com/vehicleRegSelector.do

Enter your cars registration into the box on the left or VIN in the box to the right.

The camera is NOT part of the wind screen. It is all contained in the central cluster behind your rear view mirror.

There does not seem to be a box for the VRN. Just VIN.

 

Shame the camera is not part of the screen... will pull the covers off the central cluster and see if there is anything obvious.

This could be your problem then. If its not OE/Ford glass this could be causing issues.

also noticed that the auto high beam no longer works... I used it the first night we got it and it was going a bit mental turning on when cars were coming the other way but since then it has never worked.

The system needs to be calibrated then. The alignment is completely off by the sounds of it.

Does anyone know if the cameras and stuff are part of the screen or separate? 

They are separate from the screen. In the event of replacement the trim in the centre is removed, and they will unclip. If they haven't been clipped back properly then even without a calibrating they shouldn't be this bad.

pretty sure no stop start. Will have a look and see if there is a button. Its the other halfs car and I dont drive it much.

Still having the same issues... is there a way to check for fault codes with the system to see why it is not working? 

There is a lane departure light on the dash in amber but I assume that indicates that the system is not active. Being a mechanic I really dont want to take it to ford for diagnosis but if i need to do that then i suppose I will have to lol

Can you take a picture of this because this could be the low temperature light. When the lane departure is turned on you will see lines either side of the car which will go green, yellow, red or grey depending on if you are within the lanes, getting too close or if you stray over etc. 

Do you have the picture of two cars between a lane symbol on your left stalk? Do you have a button on the end of the stalk to turn it on?

Yea it has lane departure.. I used it on the way home when we bought it.when you turn it on though the lines appear and then go straight off.

will get a pic for you of the symbol. it is to the left of where the car with the lines either side would be. small orange symbol showing the 2 lines and the car crossing the lines.
