Hi all

I have browsed the forum but cannot find anything which sort of fits my issue with my wifes Fiesta.

The problem is as follows:

The ABS light comes on intermittently, can be on from the start of driving or can come on after 30 mins or so. It may go off during the journey or it may not. It may happen daily or may stay off for days. (very intermittent)

Sometimes the Engine management light may accompany the ABS light, other times not.

Occasionally the Speedo will not work.

I have done the dashboard diagnostic test but this throws up the following

Speedo does not sweep to conpletely - just jumps a little then rests back
all appears ok with everything else except I get DTC codes E200 E197 and D262
RPM appears to be about right even with warning lights on
other than that everything else seems OK

I had a Diagnostic done by a garage. They got an ABS communication error but said this could mean a few things and not necessarily a faulty module, i.e. bad earth, damaged wiring.


I have spoken to many garages and there are lots of ideas obviously which does not help. I have narrowed it down to a few things I think are likely based on my own knowledge and what people have suggested.

1 Ford just want to replace the Instrument cluster. Nice one Ford. 200+ for the cluster then a couple of hours fitting. (I can remove the instrument cluster in less than a minute - therefore I do not trust them) Focus had an issue where moisture would get in the cluster, i have checked this scenario. The PCB's are clean and moisture free, no evident damage, loose components etc.

2 Vehicle speed sensor fault which may give ABS warning and speedo issues.

3 Faulty ABS module - but where does this fit in with the speedo issue and engine management light coming on? Ford also wanted to replace this!!!!

4 ABS sensor at the wheels.

5 Bad earth or faulty/damaged wiring.


The only other thing which may have been a contributing factor was the problems arose since a recent service. ordinarily I would not expect a garage to service brakes on a normal service. This garage does, and from experience they always do a good complete job. Better than a dealer service from experience. Would this fit in with any scenario I have given above?

Once when I was driving the car to get the problem to occur there was a strange noise from the Drivers front brake as if the ABS had actuated. The ABS light then came on.

I am in a quandry, I have not got thousands of pounds to throw at it to just replace ABS systems and clusters. I do not trust dealers, they just want to grab your money and performthe biggest jobs they can fool you into. I am not as green as I am cabbage looking and I have had a number of experiences where dealers have tried to stiff me. i.e. Your catalytic converter has gone sir - Errm i dont think so, the noise is there, the cat is there I just dont have the tools to repair the problem. Thanks but no thanks.

I would be able to complete a good range of work myself along with my fitter friend, but I don't have the Fords diagnostic computer. They want 80 which I find astonishing. The only problem is unless the car is showing errors it may not even indicate any errors during the diagnostics. The car has driven for two days now with no problem.

Could it be to do with the weather and moisture.

I may need to keep it in my garage for now which means parking my scooby outside!!!!!!!!!not sure about that one LOL!

Hopefully someone may be able to say Yeah check this or check that. If I dont ask I will never know.


Kind Regards

start with the basics first m8 check the brake pads and the wires one of them could be damaged i had a similar problem on my escort gti and it turned out to be the pads i could be wrong but its easier to start with the easy stuff also when the light is on slam the brakes on to see if the abs kicks in then u may find it could be the clock panel im no pro mechanic but i do know a thing or three

Thanks for the replies guys, your input is appreciated. I will start with the basics as you suggest starting with the wheels and brakes. I think I will also get a Haynes manual so I can locate the ABS components and inspect them and trace the wiring where possible.

It is annoying where symptoms are not necessarily caused by the system throwing up the problem.

Thx again for your replies, I will start this project tomorrow and keep you up to date should I come across anything.

I drove the car around on occasion to try and replicate the problems, typically all was fine.

My wife got in the car today and almost instantaneously the problems started.

Speedometer does not work.
Mileometer does not work ------- Displayed
ABS light on and ABS does not work.
Handbrake light on ??????
Engine management light on but was not straight away.
The car drives perfectly normal

Nothing adds up.....where has the handbrake light come from and the engine management? If it was the ABS system, would these come on?

Are ABS and Engine management on separate systems or could one trigger another.

If it was the cluster, why would the ABS not work?

Can anyone shed some light and help ascertain where I should look next.

Cannot find any evidence of anything broken corroded without stripping stuff out now.

Vehicle Speed Sensor or Wheel Sensor???????(Hand Brake light I think might be the key here)

Interested to see AndyTownys message .........

My wife suffered EXACTLY the same symptoms on her 1.4 today. No previous problems, started up this afternoon and found ABS & handbrake lights on, no odometer '------' and a speedo that bounced across to 8000rpm before settling back almost immediately to zero. Then 10 seconds later the engine management light came on too.

The car seems to run fine, with no obvious brake issues (although haven't road tested ABS!!).

Did you ever get your problem resolved as I'm not looking forward to a long drawn out saga of repairs/investigations by Ford.

PS - Interesting that you are in Lincs - our car was sourced new from Evans Halshaw in Lincs in July 06 (is this a batch problem??).

Hi - It would be good to know what fault caused the problem - similar to my mothers Fiesta 1.6 auto 55 reg. Started with ABS indication then brake warning and No speedo - all intermittent.

Any diagnosis appreciated.

Thanks

Phil

Hi Mate,
A about your problem below, i have EXACTLY the same problem with my '05 Fiesta zetec. It has been goin on for a while now, the only time it was ok for weeks was during the recent very cold spell we had which makes me think it could be moisture somewhere.....just wondering if u ever got the problem sorted?? Cheers...

Hi,

Having looked at a number of forums this looks to be a regular problem as I'm also finding out. My car is an 06 Fiesta Studio an as per previous posts the speedo has stopped working, the ABS, Engine Management and Handbrake lights stay on all the time and the central digitals display (Trip meter etc.) just displays -----.

Looks to be an underlying design problem but Ford won't accept it!!

Analaysis by the Ford dealer (cost 99) is that it is the ABS sensor and will cost 500 to replace - Gulp!!

Had faith in Ford but losing it rapidly now - may just replace car but with what make?

hi all , i have had exactly the same problems, if you are experiencing handbrake light, abs and warning lights and no speedo working its an abs module failure, mine stopped working 3 months ago took to ford which cost 70 pound and they said i had an abs module failure said it would cost me 700 pound to fix. i dont have that sort of money lying around and am in dispute with ford at present as i lease the car from them also. they will not accept that it is an underlying problem and said i am liable for all costs and repair. am going to be obtaining legal advice as this seems to be a common problem with fiestas which ford will not accept.

would love to hear from other people experiencing same problems!

Right folks ive been reading through your posts and its nothing to do with moisture in the cluster and the year of fiesta your all descripting they dont have vehicle speed sensors its all done through the abs module.

Fords not just on the fiesta but the new mondeo also have major faults with water ingress in the electronic abs module which you can replace seprately to the HCU (Hydraulic control unit) which is the mechanical part of the abs module.

The abs module will cause communcation problems between the PCM (Powertrain control module) which puts the engine management light on.

Causes the speedo not to work as it cant register the signals from the wheel speed sensors.

Handbrake light, abs and traction control lights on as the electric module has or is storing a fault code in the memory.

the led display will not work as there no signal from the abs module so cant register mileage and has communcation problems.

dont drive the vehicles and slam your foot on the brake as the abs WILL NOT work and could be dangerous.

I have had many of these and that is differently the faults you all are describing.

Fords will be very un helpful, your only chance is asking for goodwill which means fords will pay a certain percentage of the overall cost of the repair and is based on a sliding scale. the more miles and older the car the less fords will be willing to pay.

I hope this helps and please contact me if i can be of further help

Thankyou LS Auto Repair that has helped as you have said you have dealt with many. ford will not accept its a problem so i am gathering proof. yes have been to fords very unhelpful and have only offered 10 percent! 70 pound in vouchers which does not solve the problem.. will probably be taking legal action as in my rights under sales good act i believe i am not liable for the repair. thankyou for your help x

Well i hope you get it all sorted.

Fords know about it but they dont consider it a big problem as they dont have thousands come in with that fault but unless they want a thing like toyota i feel car dealers should take charge of faults like these

Hi LS auto,
Thanks for the great post. U seem to know exactly what the problem is.
I noticed my faults when we had very heavy rain, and the car was fine for a
few weeks during the really cold spell last year. I'm convinced water was the
cause but has probably done permanent damage. So can I just ask do u think
I should first replace the hydrolic control module or just the whole ABS module?
Someone also advised me to clean the ABS sensors as this could cause the same symptoms?
Ford need to accept this as a design or manufacturing fault.
Thnks again...
