ABS Processor fault/strange reference

[tzami]

Hello to everyone,
I have a Citroen C2, 1.4 HDi, which has a problem with ABS Processor (module).
I have found this part in market both in a new condition and in used (genuine in both cases).
To the Citroen Parts Application in the related figure it refers 2 part numbers (codes) for the same part........
The first is 4542F3 and the second is 4542F4. For the F3 one it refers "PART TO BE CONFIGURED"
For the F4 one refers "CONFIGURED PART And VEHICLE IDENT NO (VIN) TO BE SPECIFIED ON ORDER"
The same thing it refers as well in 2 part numbers for the whole ABS unit(assembly with module and pump together) and to some other citroen parts which i have found in the google........
Which is the difference of these 2 part numbers?the first module is empty(blank)?and the second is scheduled( ready to install without additional programming)?please reply if only you know the right answer. Thank you in advance. here is the related link

Your question isn't very easy to understand, so:

First, there are several types of ABS Blocks and ECUs for the C2 (even the 1.4 HDi) - so have you checked these parts against your VIN? If not, post up your VIN and I can check the correct one for you car.
Second - to answer you question any part that says 'To be Configured' means you it will need to be coded to your vehicle, usually with a Lexia before you can use it. The other part option is where you specify the VIN on order and they code it to your vehicle.

There are 2 separate parts - the ABS Hydraulic Block (Part 1 in the Diagram) and the ABS ECU (Part 2) and these are available separately. If you are buying these second hand from ebay or elsewhere, the seller may well be offering these 2 items together.

Before you go changing things though, have you had your car checked with a Lexia to determine whether it is the ECU at fault? ABS errors can be triggered by other problems too - so do not automatically assume it is the ABS ECU.

thank you very much for your reply......yes.....i checked the ABS figure with my VIN in a similar site and they are the same parts with the same part numbers same figure.....are the correct however......my electrician said "since you have normal braking the module is faulty...not the pump".
i have the codes of course of the processor,pump and whole unit after a visually check.....processor....10.0970-1109.3......pump.....10.0207.-0056.4
and whole the unit 9656493580 ATE
one more thing....the hydraulic block 4541G4 AND G4 refers to the whole unit....not only the pump-valve...1800 euro new.....and module 500 euro new approx.
the answer to my question is related about the "ORGA" or"RPO" or "RP" number?
in ebay i find this strange value for the module new!.....

4541G4 AND G5.....sorry

[tzami]

became 3 downloads with Lexia and the result refer to the ABS unit without clarifying processor or pump......the electrician said that I wrote above

Your RPO number is your build number usually found on the label in the door pillar. As I mentioned, there are more than one type for the C2. I cant tell you exactly without your VIN though. You may need to have this coded if buying used. I can check tomorrow for you.

[GiveMeABreak]

If one of the ABS sensors on the wheels is faulty, that will deactivate the system so you have only normal braking, so check these first.

[tzami]

you tell me that i have the RPO code to buy a used module or unit however?namely my RPO code must be the same with the crashed citroen car that was taken the used ABS module or unit?my VIN is VF7**************[VIN obfuscated, can be read by forum staff]
thank you very much for your interest

[GiveMeABreak]

No not quite. The RPO number is the build date of your car. It is used when buying replacement parts to determine the right ones because sometimes throughout a car's production run they change the design or make modifications to the parts. They may say that up to this RPO 12345 it is this part, but from RPO 12346 it will be a different part as an example. My PC is shut down now, but in the morning I'll check the correct part for you and tell you your RPO, ok.

that are you say I have encountered/met only related with the VIN numbers....."as of " VIN1......"up to" VIN2......
I will await for your reply.Being well

The VIN number is usually clearly indicated somewhere on the car. There is normally a small 'window' in the black border of the windscreen, lower left, with the VIN visible here, and another place it can be found is on one of the wings (normally right hand side) where it would covered by the bonnet. Normally 15 characters long, mixture of numbers and letters.

[tzami]

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.......

Ok, I have just checked all the parts for your car:
Your RPO is: 10270

4541 G4 is the complete Hydraulic Block and the combined ABS ECU
4542 F3 is just the ABS ECU on its own.

When you get one of these you will need to have it coded. Generally using a Lexia, you will need to input several bits of information such as Engine type, wheels, rear discs outside etc., as the ABS ECU needs to know all this to operate properly. I believe it can be coded using the new parts section of Lexia. The ABS System is a TEVES MK70. There should be several options shown on the screen when doing this that will ask you for the relevant information.

I am emailing you your specs, so that you can see the relevant info. You have Discs (TRW Lucas) at the front (Diameter 266 EP13) and Drum Brakes (Diameter 203x38) at the rear (either Bosch or TRW Lucas) as fitted at the factory.

I think the answer you are looking for is, if you buy 4542F4 you will need to tell the seller your VIN number. Then when the module arrives, you can fit it and it will already be coded to your car.

This would be the easiest option, since you should be able to just fit it and drive. (The F3 option is blank and would need Lexia to program it with your VIN after it is fitted.)

However, as GiveMeABreak said, do check all 4 wheel sensors and wiring (and fuses relating to the ABS system) before spending a large amount on the module because you may be lucky and find it's a cheaper solution.

@ 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?
