ESP Not working

[Dantis]

Hi, I am assuming this has something to do with the upgrade steering wheel I have just had fitted, it is the Focus MK2 wheel with cruise control.

I haven't wired in the cruise control wires yet so it has not been activated, but I noticed that the ESP light does not come on at all nor does the ESP switch do anything.

I have read that after fitting a Focus wheel the SAS has to be reset, when I get the cruise control activated and SAS reset will that cure it?

Many tnanks.

Did you change your bcm?

[Dantis]

No, I have changed the steering wheel to Focus Mk2 with cruise, plus upgraded to high level clocks/trip.

ESP was working so has to be something to do with the steering wheel?

Clocks need configured using ids

[Dantis]

Clocks? I read that only the temperature sensor needs to be activated via IDS.

If you have a 08 on bcm and apre 07 set of clocks (green band between 1500 and 3000 rpm) the esp wont work properly this happened on my van the later van bcm is set up for hill start and up shift and the earlier clocks arnt This happened with my van I fitted matching clocks an bcm I got all back least ways thats my experience but I could be wrong

[Dantis]

No I have the red line clocks the same as what I had.

Hill start works fine.

[Dantis]

When I turn on the ignition the esp light doesn't come on if that helps?

My 2007 2.2 tdci swb failed MOT on ESP switch! The MOT guy reckons it is most probable that the switch is faulty- It behaves like this: at ignition, the switch lights up like the rest of the warning lights on the clock ( it is green banded by the way), and then goes out with the rest of warning lights after the PCM system check is completed (is it bcm or pcm? better still 'ecu', same thing like 2 halves of Twix). Then when engine is running, pressing the esp switch doesn't do anything ( at least anything that can be seen visually), no warning light on the clock/ dash/ or even the switch light itself. The MOT guy says the diagnostic does show up any code ( I am not sure if he checked it or not) but my Delphi diagnostic doesn't show any fault code either. So I ordered a second hand from ebay, the seller swears by it working perfectly. But, same result.
My first reaction to MOT failure was that it cant be the switch. So if not, then where to look for fault considering no fault code! Please don't let be pcm (bcm/ecu?)!

Looking for some inspirations- Many thanks

So here it goes! As no new inspiration is forthcoming via forum, I shall continue my rant to myself:
Tried a new esp switch- same thing! Puzzelling over no cluster warning light, took out cluster and stripped it. Found out esp LED covered by black electrical tape!!!!! Some clever boy in the past! Now at least I know esp is faulty. Still puzzled by why my Delphi diagnostic sees no code! Disconnecting esp, abs, or removing fuse to do with these, does show dtcs. Is it the cluster? Is it the yaw? Is it the steering sensor? Which? What? When? How? Help! Help! Help!
Ordered a yaw and pondering if should order cluster! What to do next. Come on forum gurus; some sensible input for a change- not break in cct fuse 26 to some unknown point or map sensor! The first one to suggest a working solution will get 2 pints worth transferred into his account!
And why is there no circuit diagrams of esp abs yaw steering angle, abs sensors etc in Haynes manual? What a waste of £25!

Esp has 2 modes.
1. Hard fault occurring which will likely store a fault code that can be read.
Fault sensor/wiring/reluctor ring,abs module/yaw sensor/strong sensor etc.
Usually these will indicate a fault and possibly leave the esp light flashing or whatever but in the case of esp you'll drive off and the van will judder and the esp light flash which indicates a fault and limited operation of esp in effect, may also be other things or even not.


2. Soft fault occurring only when vehicle is in motion, this indicates either of the sensors or modules is working but it's out of range and will not store a permanent fault which can be read but will throw a warming lamp to indicate that something isn't right, usually it is getting the wrong information back and activating the system believing the vehicle to be in danger.
This can be mud on the reluctor ring blinding the sensor/steering angle sensor not calibrated (new steering wheel that isn't the same angle) also changing squib and some don't have the sensor in i did that one lol wtf? , incorrect tyre size also changes the rolling speed of the wheel sensors,yaw sensor calibration, although I've not had any problems with that tbh.


If you have no fault codes then your reader either can't read Ford Abs faults or you have a soft fault.

You need to establish if you can read live data.

Does the esp light come on now you've removed the tape from the speedo? I'm thinking it must be on when driving but not when parked although i believe that if it comes and goes regularly then it may stay on permanently in the end and will need clearing.


If you have ids then read codes, read data logger and check the 4 wheel sensors are similar readings, calibrate sas and yaw sensors.

Hi loot thanks for excellent description- since my last input, I have found more crimes: the cluster pcb had been modified ( cut track and wire soldered) to feed abs light such that it would go off after initial test; showing no fault of abs possible for mot purposes! I ve turned it back to the way it was before as original. As expected now both esp and abs light are on which points to abs fault. This explains a lot and now I know where to look: abs. As you said, my diag doesn't do brakes at all so first I need to get it idsed. But the wheel sensors I think are the first port of call. Just to confirm, both lights are on from engine start and driving-wise, I haven't noticed any issues and in fact on hard brake, the pedal pulses as abs kicks in!
I will report when the codes are read next week. I m guessing hard faults all the way.
Many thanks

Remove switch, fit blank in its place. Job done

Only Ford ids will show all relevant codes.

It appears my previous to Ake was not published!
It went like this: its too late now as it now shows in mot history!

I have been looking on ebay for a good abs pump assembly. The exact part number 6c11-2c405-BD , is priced a bit more than the AA to BC (last two characters). I wonder if fitting any for the years 2006-2013 mk7 production years would be ok but needing programming after installation.

Can I do that?

Thanks for advice.

My 07 van had abs and esp but i upgraded to the later red band speedo and i couldn't get hill launch assist to work, i had to buy later abs pump and yaw sensor.

Abs and esp will work but hla won't.

I did a thread about it somewhere I'll have a look but it may be in my clocks thread
