I have been getting intermittent errors, "asc not available, Traction not available, and goes into fail mode". When it does happen, I can turn the car off, wait a couple of minutes and start it up and it would be fine. Any help on why this is happening? I hit a pot hole over the weekend but drove for 100 miles and went out the next day to the store and low and behold.

 

First off how old is your battery? these cars are very sensitive to low battery level, and this is a classic warning of battery past its best....
Another thing
It could be a dirty wheel speed sensor, they're bolted to the back of the wheel hubs, they might need a clean. What do you mean by fail mode?

 

Hey Sean the battery is about 5 years old now and that was fail safe engine mode. (sorry)

 

I agree with Sean. It could be the ABS module but first rule out the battery and alternator. My alternator had lost a diode or two so wasn't putting out a good enough charge at idle so I would get the same lights minus the FSEM. Car always started fine, ran fine, etc. It was just putting out 11.5 volts at idle, 12.8 at throttle. Get both tested and post up the results. One thing to note is I know mine won't rev beyond 2.5 or 3k in park. It hits a rev limiter so you may be able to do the load test in neutral. Most autoparts places will test both for you at no charge.

 

If you get "asc not available, Traction not available, and goes into fail mode", WITHOUT an ABS light, the problem is either the battery or throttle body. My car did that a few months ago and it was the throttle body connection that needed cleaning. It only happened occasionally on mine, and when you hit that big bump, it may have slightly moved the throttle body connector around.

No ABS light means its not the ABS module. ABS problems usually wouldn't cause an engine Fail Safe mode.

 

Thank you very much for your assistance i found an older thread very helpful https://www.jaguarforums.com/forum/f...splay.php?f=27

I am so glad I came here before I called AAA to tow my baby to the dealer as most of you know it might have been a costly affair had I done that. I purchased my baby off the showroom floor in 2002 and money then was not an issue but today, different ballgame. I am watching every dollar. So after about three hours and a ten dollar ratchet from the auto parts store I am a little bit sore but my baby is running fine.

 

A year ago I purchased new breaks and rotors online that were suppose to be compatible with my Brembo originals. I now get a wobble when braking it down from high speed and they are squeaking like crazy. so much so that I am embarrassed when pulling up to a light. HELP!!!

 

You need to have your rotors turned.
I will guess that it is the front and you can feel it through the steering wheel when you brake?

Since you rotors are cross-drilled ( or they should be ) you will have a find a place that is willing to do it.
A lot of shops don't want to do it because they say that the holes will damage the cutting tip on their machine but it's BS.
Just need to be done slowly and making a few pass taking only a little bit of material each time.
A pair of new front rotors should be less than $250 including shipping.
Let me know if you need the link for thoses

 

I need the link for the rotors, front and back for my XJR 100 with brembos, and pads too please. thanks.

When I had the ASC/Trac Not Available message, I had the ABS sensors cleaned, which solved the problem. However, my car never went into failsafe mode.

 

First link not working.

 

Fixed. go back to the post and click on the new link

 

Now says I have an empty shopping cart.....

 

Let's do it that way, go to their website/call and the part # are:
Pair of front rotors: JAG000308 price $212.58
Pads: JAG000079 price $31.11

 

Thanks again Luc
Thats a great price for a pair of front rortos! Why are the rears so much more, or is it a mistake?

 

Not sure what you mean on the link the price is $253.95 for a pair , only $50 or so more than the front.
I know that their website say " sold individualy" but that mean a pair. They should word it better

There is only 1 after-market supplier of those rotors, front and rear ( Eurospare form the UK) and they only come as a pair in a single box

 

As usual, you have helped me again, thanks Luc!
