I have battling for a few weeks to diagnose/fix/replace all kinds of issues causing the Check Engine light to come on.
New O2 sensor fixed.
Ran some CataClean through the gas to try to fry out anything in the Cat Converter (seems to have worked, btw....).
Replaced PCV hose (should have done this a long time ago, I know).
Reseated brake booster hose.
SeaFoamed engine to burn out anything nasty in the top end (wasn't much in there).


Anyway, took it out for a test drive today.
Ran like a champ. No issues on my 10 mile test drive. Revved it hard....dropped it down into manual shift and gunned it for a bit.....no problems.

Got back into my driveway (there is still a lot of snow) and almost got stuck.
Had to REALLY sling it around to get it through the snow.
(Meaning, I was going 30 mph on the speedo, but in reality was just creeping along.)

The ABS light came on.

No check engine light.....but this one I haven't seen before.

Any thoughts on how to diagnose this latest money-sucking venture that I call a Jaguar?

I am about ready to drive it into a tree.

First step would be to read the diagnostic code. This will be a chassis code, but a lot of readers should be able to read it. The code reader at my local Advance Auto Parts can read the code, but it doesn't explain what it means. For that, you can turn to JTIS, use the search feature on this forum, or just ask.

Thanks. I didn't realize that the ABS light would actually throw a code. I will put my reader on it and see what it says.....

As you were "slinging it about," the wheels may have all hit wildly different speeds. This makes the ABS unhappy, so it turns on its unhappy light.


You may have to reset it, but it seems likely there is really nothing wrong.

No code in the computer, took it out for a spin, and sure enough, the ABS light went off.

(Of course, later on that trip, the check engine light came back on, but that's a different issue........)

Thanks!
