Recently, I parked my XJ6 in the airport in sport mode, six days later I came back and saw that my traction warning light and brake light are on in the instrument panel. I rarely use sport mode, so could this trigger the problem? we did a battery reset and the lights are still on. any ideas? thanks so much

 

Welcome to the forum. There is not much chance of sport mode causing the error. Are you referring to the ant lock warning light? It could be a dirty sensor, broken connecting wire or a fault in the ABS module. Without the relevant codes, it's hard to tell. Unfortunately, generic code readers cannot report brake system codes, and you will probably have to visit a specialist or, last resort, dealer to get the codes.
Are you able to do your own maintenance and repairs?

 

I can certainly try to do my own repairs, if not, I have friends and family that could help me. And in response to your question, yes the ant lock is on as well as traction is off and I cannot put it back on.
Thanks so much

 

If you need repair manuals, I believe they can be found in the HOW TO sticky, or you can buy the Jaguar Heritage CD on ebay.

 

Dexter:
That warning, as are several others, is common after a low battery voltage episode- like leaving the car sit. See if it does not go away after the battery has had a chance to come up to snuff.

 

How concerned should I be? Its driving just fine. I'm wondering if it's a misread electrical problem or a actual anti lock brake or traction problem...

 

Again, if it goes away, it was probably just the battery voltage. If not, it is likely the motor power circuit connector on the ABS module, or a dodgy wheel sensor. Tyr restting the ABS module by disconnecting a battery lead, wait a few seconds, then reconnect. Start the car. If the light comes on immediately,it MIGHT be the motor circuit. If the light comes on after you are moving, it MIGHT be a wheel circuit. The best way to remove the "MIGHTS" in the explanation is to read the ABS module code, but a standard OBD scanner will not read them- that takes a dealer level software with Jaguar specific code capability.

 

I don't have traction control, but when I had the ABS motor-circuit issue, the ABS light was always off on startup and illuminated after 100 yards or so of driving; generally same spot in front of my neighbor's house.

As to concern, I can't think of a fault that you'd exacerbate system damage by driving it - just beware that as long as you have the lights you don't have the systems - so steer clear of situations where you need anti-lock brakes and/or traction control.

 

aholbro-
Wow, I thought my wheel sensor behaved that way, but the motor circuit happened on startup. I certainly admit my memory ain't so good,

 

It may have, Ross....I haven't experienced a wheel sensor issue yet...only the motor circuit...and for several weeks (before I got Bob to read the codes and confirm what it was) was always hopeful of a blank panel all the way to the end of the County Road (about 1/4 mi) but of course it never was to be. So I have less to remember :-)

Worse still, after my first attempt at repairing it....cruising in front of neighbor's all confident and smug...and bam! ABS light! Fortunately, I wasn't THAT confident before the check-ride and only taped it back together!

I thought maybe they ran a different BIT-check if you also have traction control or something?

 

Ok thanks everybody. I have the same problem of the light being off on startup but halfway down the road they come on. So it could be a wheel circuit or sensor I'm guessing after reading...?
Thanks a lot guys!

 

Well, according the the aholbro, it could still be the motor connector. Look in the archives about that- the ABS pump motor plugs into the module with a two prong plug and the solder connections come loose. There are folks that fix them for less than $100., or you can saw the module apart and solder the connector yourself, or you can drill two holes in the case and do it that way, simply taping over your drill holes with some high quality sealing tape of some sort. Again, much is in the archives. I advise getting the manufacturer specific codes read by someone before tearing into it.

 

Codes=goodness
There's a good thread here started by Motorcarman how to fix the module - search on the pump fail code C-Something, I can't remember, think it ends in 19

 

Sorry it has been so long for a reply. I think it was just the battery because I've been driving it more often and the light went off!
Thanks for everybodies advice!

 

I want to mention that on the Traction Control Actuator(MNA5930AA), at least on the X300, the two wire's insulation on the unit just crumbles eventually and the wires short out. I have seen this happen to several. On my own the ABS and Traction Warning lights went on. Eventually I found that the wires on bottom of the unit had shorted, but the upper end looked good. Some I have seen are bad at the top and bottom. It may be due to UV since the insulation under the black wire tube seems to be ok. I have not disassembled the unit to rewire it. I hope that the shorting did not permanently hurt something. I have not seen this problem mentioned and wanted to bring it to someones attention. Anyone with an X300 and traction control should be aware of this problem.
