Re: ABS Processor fault/strange reference
If you have established without doubt that the problem is a defective ECU, why not try to repair it.
Normally a case of cutting the top off the unit and soldering the pins, got to be worth a try if the unit is faulty and needs replaced, you have nothing to loose and may save yourself a lot of euro's.

Re: ABS Processor fault/strange reference
Yes, they are just the part numbers - one that is ordered blank and needs coding or one where the VIN is supplied and coded prior to order. (That site is just replicating Citroen's service information).ekjdm14 wrote:@ Givemeabreak, I'm looking at the first link given by the OP and (from what I gather from that site) the 2 options F3 and F4 are either blank or pre-coded to a supplied VIN number?
There are not many second hand suppliers that code these - they just tend to supply the used unit and it's down to you to code it on fitting.

Sorry, missed that post.tzami wrote:I know my VIN number...i wrote it above....and where it located on my car......the hot-main question is what programming/schedule (with lexia maybe....) procedure must be followed to install on my car the ABS module 4542F3 or 4542F4 (new both).........???the reference/notification for each part number i wrote them in the first reply.......

Re: ABS Processor fault/strange reference
Therefore/consequently.....If i buy ABS module 4542F3 (blank) it must be coded from my technician after install on my vehicle with Lexia by using my VIN vehicle specs which send me Marc in my email......as also a second hand ABS module or ABS complete Unit which comes from another citroen car which have at least one different specification.....even if it is the same car with different VIN......For the option of module 4542F4 must the seller to ask me my VIN to coded the ABS processor and send it to me ready to use........do i have a mistake so far?
The RPO number it will be needed in the procedure of coded/programming the module or unit?

Re: ABS Processor fault/strange reference
Most, if not all second hand used units will already have been coded to the original cars they were on, so you will need to re-code them when fitting to your car - and yes, you will need a Lexia to do this. Unless you are buying a part where the supplier will code it for you (using your VIN), then assume that you will have to do this yourself. You are correct - even if you have an ABS module from an identical car, there may be some differences in the specification / options, so you will need to make sure it is coded to match the kit on your car.
The specs I sent you contain the basic components fitted to your car as it left the factory.
When you come to code the unit using a Lexia it may ask you for your RPO number, which you enter into the system (this is so it knows what components should be there according to your build date). If using Diagbox (the newer software that includes Lexia) it probably won't ask you for the RPO number. I have just included it in case you need it.

Re: ABS Processor fault/strange reference
I take it no one though my idea of trying to fix the ECU was a good one
Failure of the ABS ECU is a common problem on a lot of cars and in most cases it's nothing more than a loose connector pin, it seems to be a lot more common since the use of compliant pin technology on the ECU's.
Cheers.

Re: ABS Processor fault/strange reference
It's a good suggestion , but TBH I wouldn't want to be bothered with all the faff as my soldering skills were ok, but not so much anymore. It's a plug and play world we live in now! I would just want to get the old one out and the new one in and be done with it.uncle buck wrote:I take it no one though my idea of trying to fix the ECU was a good one

Re: ABS Processor fault/strange reference
I would guess that what some people are doing is to get a replacement module, swap it with the defective one (so they can get the vehicle back on the road ASAP), and then see if the original can be repaired (if it can, they do so and then flog it on).

Re: ABS Processor fault/strange reference
Quite possible James, but you'd still have to test the one you repaired before flogging it - otherwise you'd have all the hassle of buyer returns - and more faffingHell Razor5543 wrote:I would guess that what some people are doing is to get a replacement module, swap it with the defective one (so they can get the vehicle back on the road ASAP), and then see if the original can be repaired (if it can, they do so and then flog it on).

Re: ABS Processor fault/strange reference
Well....so....let's try to strain at a gnat.....pins on connector at the ABS unit (jack....steady/stable) are male.....pins on movable connector are female....
Of course at the procedure of removal the ABS unit from the car will become visually check on the pins.....both sides.....Suppose that we find a broken pin on its base.....and after?and then what?we soldering to create the pin of the zero/beginning?fortunately the most pins on the aircrafts are replacement without soldering....and the few which need to solder to replace them are cut and solder.....nevertheless on the automotive industry the manufacture doesnt care/prevents about cheap clever solutions to fix simply the fault.....they tell you....buy whole the component!!!!!!other solutions are patents not for many years.....maybe it is possible......what else can I say?In greece/athens repair level.........ATE/TEVES ABS Units not repair.....i ask and the answer is negative.....only repair BOSCH ABS units.......

As far as I can make out the OP is looking at having to spend in the region of 500 Euro's on a new configured ECU, so you would think anyone would be more than eager to give fixing the defective unit a go, especially as there is nothing to lose.
Pllug & play world....exactly....with the internet, and forums like this one, we have never been in a better more informed position, there's even videos on you tube with people fixing similar ECU's.
I'm of the mind that if you dismiss all of that and would still rather hand over 500 euros then you must have more money than sense.
Maybe I've just been watching too many Russian youtube videos, those blokes will have a go at fixing anything and they make a good job of it.

Re: ABS Processor fault/strange reference
Fair enough, but I was looking at second hand ones that are about 80 Euros or so, not a new one as such, which is why I personally wouldn't bother if it was me.

Re: ABS Processor fault/strange reference
A similar ABS ECU being repaired.
Notice the pins are not soldered to the circuit board but are a push fit, this is compliant pin technology and is used on most ABS ECU's these days.
In the video they guy just tweeks the pins to remake the connection, personally I would favour soldering each pin.
Cheers.
