I've been reading the forums about this, but have 2 questions. Setup--I replaced the left front speed sensor after having Jaguar diagnose this fault. Now, 2 months later, it is back. It was a used sensor. When I removed the original, I noticed the end was wet. Pulled it again yesterday, wet again.
Question 1-would water inside the plastic bearing cover short the sensor permanently? I have a new factory sensor, but don't want to install it if I'm just going to kill it. Solutions are drilling a small hole in the bottom of the plastic to let the water out and see if that helps, or replace the bearing assembly - again.
I purchased a used ABS control module after reading all the posts about the pump pins on the circuit board. 15 minute job yesterday to swap out the control module, but fault remained. So, I am assuming for now that my ABS module does not have the pump pin failure noted.
I also read about the British Diagnostics JLR cable and software kit.
Question 2 - Has anyone purchased and used that successfully? It's that or another trip to the Dealer to have them tell me what's wrong. Same money.
Any help is appreciated.

 

First thing-has the sensor failed or is the water interfering with the sensor?

I think I am right when I say that there are just two pins on the sensor-it is actually a coil which produces a magnetic field and the reluctor ring interferes with this field.

When the sensor has failed the pins will be open circuit so you can test it with a DVM.

The water will not kill the sensor IMO but you need to prevent the water ingress.

The gap between sensor and ring is critical so the water could be interfering.

 

Many members have the mongoose cable and sdd software

Personally i would say its a must have tool even if you only use it to make sure your being told the right thing

One of the things you can do is read/log the sensor data to diagnose faults like yours.

You can also setup for live recording. IE record the abs sensors go for a drive and after the fault happens download the recorded data

I purchased my mongoose cable from uobd.com

Thanks for the replies. I've read different ways to check the sensor, volts and ohms, and I really got nothing either way, except that it certainly isn't open, 1.8k ohms if I remember. No change passing it near metal or even a magnet. I cleaned it and put it back in, but no change. The bearing assembly is only a year old and I hate to do that again. I think getting the software and cable probably is the long term solution.

 

There have been faults reported with sensor wireing and connections.

 

I've just ordered the British Diagnostics JLR software and cable. I'll let you know how it works and what I find.

Thanks

 

BTW If there is water in the hub and it has been in there for some time the reluctor ring could be corroded.

 

very curious how the mongoose works out. Where can you purchase one and the cost?

I have intermittant ABS/traction control errors. I can clear the random codes by disconnecting and then reconnecting the ABS pump connector.

Also find it surprising that there is water in the hub. I would think it would drain right out unless there is a great deal of debris around the hub.

Hi ryejag,

See Post #3 in this thread.

trying to investigate purchase of mongoose on uobd.com. Would appreciate your guidance.

thanks

I have found the link you were referring to uobd2.net They list a tool which mentions support back to 2005. Not sure if it will work for my 2004 XJR, which was built in 2003. Sent an email for clarification

RyeJag

 

This has come up a bit, see the mongoose thread.
It will work with all the X350's including the 04 XJR

I can doubly confirm that as I have the 04 XJR as does Cambo

I haven't tried the product from upbd2.net. Maybe I should have since it is less expensive. But the British diagnostics seems to have everything I need and since I have it on order, guess I'll find out.
As for the water, the front bearings on the 04 are sealed, black plastic cover on back. The reluctor ring looks nice and shiny. My main question was whether moisture would kill the sensor permanently. I don't want to put a new one in if it will be destroyed in another 2 months. So, I will see what the software tells me when it arrives assuming I can get it working. If it is the same wheel again then either the used sensor I bought failed in 2 months or the moisture in the bearing housing is killing the sensors, which means a new bearing/sensor assembly. Just want to be sure before I buy anything else.

 

ryejag, I purchased the JLR SDD software and cable from British Diagnostics on ebay~$145. It works perfectly. My problem is the left front wheel speed sensor. I won't go into all the detail, but I've ordered the complete hub assembly and cable. I suspect a problem with the reluctor ring since this is 2 cables in 3 months. Don't want to ruin a new and expensive Jaguar replacement. The entire hub assy is cheaper from Timken. I was also able to use the software to reprogram the mirror autodip in reverse to not dip. Great software. Essentially plug and play. The JLR SDD manual is also available for download as well as the VMplayer user guide. The SDD software runs in XP in virtual machine mode on a laptop. Just follow the instructions to install the software, plug in the cable and go to town. Well worth the money.

 

Sorry, I meant to post the link to the software on ebay. Jaguar Land Rover Diagnostics Coding Programming Kit Dealer Software IDS SDD JLR | eBay

 

The JLR SDD software confirmed the issue was the left front wheel sensor. I replaced the entire hub assembly with a TIMKEN HA590224 from Rock Auto since that is cheaper than just the cable from Jaguar. Immediately on startup the Trac not available light went out and as soon as I moved the car the ABS light went out. Problem solved. Will never know exactly what happened, but the magnetic pulse ring in the old hub had a small ~ 3/8 inch section damaged. Looked like it had started to delaminate. Can only assume that's what caused the issue.

 

Just bought the Jaguar Land Rover Diagnostics Coding Programming Kit Dealer Software IDS SDD JLR. Do not need it right now but I am sure I will at some point. Does anybody know whether it can over ride the speed limiter on a 2005 Jaguar XJR. I doubt that I will try for anything higher than 130 anyway.

 

I think it can , Newest V139 JLR Mangoose SDD software has been released today. it can support car model Jaguar and Land Rover after 2005 and update by CD.

good info on the ABS sensor, I believe I have the same problem on my 2004 XJR. Any issue getting the old bearing out? Torque for the bolts holding the bearing flange?

thanks
