I have just needed a replacement ABS controller which has sorted my ABS issue.
For future reference I am wondering if the until was used in other makes of car. E.g I have seen one from an Audi 80 at a tenth of the price it has the ATE number 10.0935-0094.4, whereas the XJ-S one is 10.0935-0030.4
Are they interchangeable?

 

What do you mean by controller? ECU? Valve block? Master cylinder aka actuator?

 

Hi Daim

I could be wrong but think that this Part Number refers to a 'Black Box'

 

Indeed it is the ABS ecu. Daim, I thought I was being helpful by quoting a part number. It is called a "controller" on the part itself, and a "control module" by Jaguar themselves.

 

It would be great if you could add a signature to your account that would let us know what car you're talking about?

 

It is an xj-s ! The part number applies to the 6 and 12 cylinder cars, I think

 

Ah, ok... I presonally don't think it would be clever to simply change to a differemt number, as it means, that there are differences in programming. For example the Audi 80 weighs a 'tad' less. It is also a FWD car amd has a totally different handling resulting in a different brake setup and braking requirements. Changing the ECU for one from a totally different car as such, can result in a lot worse braking balance as compared to the standard one...

 

I guess you may be right. However I don't know too much about electrics. I imagined the ecu receives signals that the brakes are locking and modulates them accordingly to prevent the lock up. I did not think the weight of the car or whether it is fwd would mske a difference.

The XJS was produced from 1975 - 1996. I have the Teves IV ABS system. The early 1995 models have the Teves III which was the ABS of choice for a number of years? I believe the first XJS' with ABS appeared in 1989 and I am assuming it would be the Teves Mark II, but I am just speculating.

In any case, for future questions, you may want to save yourself some trouble and just specific what MY and engine you have. Adding a signature will only take you a minute.

 

It actually does matter a lot. The signals are processed in the ECU. If the chips have a different programming, they will will react differently. Either open or close the lock. Also the sensors can and will be different as Bullitandy has noticed. The outboard rear brake XJS models have different sensors with patterns as compared to the nor al XJ-S and XJS with inboard brakes. So the ECU will also be accounting for differences in sensor signals on different channels.

I have no idea what sensor the other ECUs require, but I bet they are also different.

 

This was, according to some sources, also used in the XJ40 which was over 100Kg heavier than my 3.6 XJS with inboard brakes. This is interesting given previous answers.
Edit having looked further into it, this may not be the case!

Yes maybe but don't forget, the V12 weighs a good bit more. It doedn't have to do with weight as such but weight balance and drive axle. A FWD car with a 80:20 weight distribution (there are some) will handle totally different under braking conditions (worse) than a 60:40 or 50:50 car. And then if all the weight is behind the rear axle (Porsche) then imagine how that will react.

There are many factory whoch contribute to the way a car will handle under braking conditions. It isn't only the weight. Even such details like castor and camber and toe in toe out... Heck, even the spring rate of the front/rear axle will change the braking and therefore make a different ABS mapping a requirement.
