I have just read up on “reluctor rings” (something I never knew existed, until today) My question is, are there reluctor rings on a, 2003 Xtype,2.1 V6, right hand drive, automatic Jaguar two wheel drive ?

They are used for ABS so does your car have ABS?
If so then yes it has reluctor rings.

Perform a 'search' for Jaguar X-Type wheel bearing installation and there will likely be a warning about correct bearing orientation.

Thank you for your assistance and making it so easy to understand. Yes, my car has ABS, and so, as you have said, it therefore has reluctor rings. The reason I know it has ABS is, the light remains ON, on the dashboard, when the car is started. Would this therefore indicate, that there is a problem with the reluctor rings, and if it is, are they difficult to fit. I must admit, in all my years of tinkering with cars, and my years as a mechanic, back in the early 60’s, I’ve never heard of reluctor rings, but I’m quite excited that this “might” be the answer to my problem. Docko…

 

If the ABS light is ON then there is a fault with the SYSTEM. (reluctor rings may or may not have anything to do with a fault)

Getting the DTCs from the module will get you started with a diagnosis to narrow down the problem.

 

Thank you motorcarman. I’ll book a date and time to have my car checked on the computer, and hopefully narrow down my problem to a repair.

Docko, reluctor rings are in the bearings for your wheels. They serve 3 functions for the car, the ABS as you know, the speedometer, and for the dynamic stability control (if equipped). As was stated above, if you have an ABS light on, get the codes read. There are specific codes if the computer is not seeing one of the sensors. But, the ABS light being on can be caused by many other things.

If you want to know more about the reluctor rings, let me know. i can explain how they work and any other questions that you may have about the ABS, speedo, and/or dynanmic stability control.

 

Hi there Thermo,,, my cheap diagnostic fault finder, brings up 4 faults, which are as follows; P0057… P1646… P1647… &, C1165. I’ve purchased and had the speed sensor fitted to the right hand side rear wheel. I’ve also removed the intake manifold removed and a new lower O2 Sensor fitted, and everything back in place. However, the ABS light remains ON, and once I get the car up to normal running temperature, turn the engine off, do my shopping (one hour) and return to the car in order to return home, the Gearbox Fault sign is displayed on the dashboard, and the car seems to remain in 4th gear. I can delete the fault, so that the car can start off in first gear, but I have to continue pressing the delete button because, the sign comes straight back and the gearbox immediately goes into 4th gear. ??

Can you clear the codes and drive some more until you get a fault?
Maybe we are not seeing new codes after your work?

Generally the rings are not the problem as they are just passive bit's of metal. They can be damaged and also can pick up metal bits. Usually it's an ABS sensor.

Docko, you may want to check the wiring to the ring you replaced. It is a common issue to have the rear wiring get damaged over time. SO, replacing the reluctance ring may have moved the wiring to make the light go out for a short period of time. That is what it is sounding like to me. I am on travel at the moment and don't have access to all my books. But, the C1165 I know is for the wheel you replaced the ring on, but that is just a code for saying that it is not seeing the pulses the sensor makes, which can also be a wiring issues. The P1646 and P1467 as I recall are related to the O2 sensor issue you are looking at. So, for the reluctance ring issue, look for damaged insuation and anywhere that the wiring makes a funny, sudden change in direction (indicates a broken wire).

 

Hi Thermo, We are obviously in different time zones ? because it’s not yet 6:30 in the morning here in Queensland Australia, but it is mighty cold, as we are in the early stages of winter. But, to more important things. I haven’t yet fitted any reluctor rings, only a speed sensor to the right hand side, rear wheel. But Thermo, I didn’t follow the actual wiring for it, I just unplugged, and reconnected. So you could be onto something here. Can you advise me as to where the wiring goes from/to ?
Docko

 

Hi Thermo, and to ALL you very kind people of this Forum. This is just a short comment on my problem car. Once the car settles down after a run, and the Gearbox Fault shows up on the dashboard of my 2003, Xtype, 2.1 Right Hand Drive V6 Jaguar, the speedo doesn’t work while I drive it home. I’m saying this Thermo, because you said that the speed sensor or reluctor ring, operates the speedometer ?? But if can tell me where the wiring goes to/from the speed sensor that I fitted, then I will check it out today, and if it requires replacement, then, that’s what will happen.

Docko, the ABS module is in the engine bay. The ABS computer sits on top of the ABS unit. The wiring runs from that computer to the wheels. The signals from the 4 wheels gets averaged inside of the ABS computer and then is put on the CAN bus to be sent to the ECU and then on to the instrument cluster. So, if you are loosing the speedo, then you have 1 of 3 issues. You either have 2 bad reluctance rings, an open in the CAN wiring somewhere between the ABS unit and the instrument cluster, or you have a bad ABS unit. Based on what you are describing, I would venture to guess you have a bad ABS module. That would explain all the tranny and ABS issues that you are having.

If you would like a set of diagrams for your car, then PM me your address. I will get you the diagrams and any other info that you might find of interest that I have.

As for time, we are probably about 12 hours apart. YOu are in Australia, I am in the crazy place that they call Washington DC of the USA.

 

Hi there Thermo, in that wonderful state of Washington DC., USA.
Many thanks for your valued information re. the ABS. So, is there yet, ANOTHER O2Sensor at / beside / underneath, or near, the ABS itself ? The person who designed this car, MUST have had, shares in the manufacturing plant of O2 Sensors. (I’ll leave that alone, just in case I’m correct) But yes Thermo, I’d certainly appreciate that printed material you have on the Xtype 2.1 Jaguar, so my address is;;

I’m still getting ready to go to see my friend Joe Goodall, fight for the heavyweight boxing belt, tonight (our time) in Queensland. Living alone can be a burden at times. Talk soon, & thanks again… Docko

 

Hi there h2020

Sorry it’s taken so long, but here’s the reading on my clock;;
251,125 Kms
now I’ve no idea what was on it when I bought it just over 3years ago, but I’ve NEVER changed the gearbox oil ? So, I’ve booked it in to the garage to have it done, but they can’t do it for two weeks…

Docko, I do not need your physical address. I need your e-mail address. So, please PM me your e-mail address and I will electronically send you the documentation. I will look at what I have and send you what I think will be beneficial. I ask that you PM me your e-mail address to prevent you from getting e-mails that you do not desire.

 

Hi Thermo,,,,
Sorry about that, I’ve not really caught up with technology, (even though I pretend I have to my children) who are not really children anymore… but my email address is;
adockcom@gmail.com

Don’t worry about other people sending me emails… 🤓👍🤓
