Default RE: abs warning and trac/and asc failure light on

I've had the same thing 3 times now, and it's always correlated to hitting a pothole. I guess I may have a slightly loose connector somewhere that gets upset when the wheel (always the left front) goes down a hole in the road (There are lots here in Cali)

The fix is the same everytime. Stop at the next traffic light (again, there are many in Cali). Switch off, restart and all is well again.

The connector is a possiblity, also a bad wheel bearing can cause this. Wheel bearings fail regularly on the XJ and XK models. We sell the nut removal tool for $150. Also, a bad ABS sensor could be at fault. They are expensive, but don't worry, we don't sell many of those. Start with your wiring idea. It's least expensive.

Hey SARC, I'm just starting to get the PotHole Issue. Did you ever find a definitive fix for this? I've been doing the stop and restart "fix", but I don't want to be stranded away from home some day.

Thanks for your input.

Or get someone with the factory or AutoEnginuity Jag specific software to interrogate the ABS module for codes. Then solve the problem it points to.

Default Usually a false alarm

I've had this warning come up sometimes with my last 3 XJRs, at first it worried me, now I just ignore it, since it goes away when you stop and restart, and ABS worked normally (I did a test on a gravel surface and it chuntered away happily). But I'm no expert, so get it checked just to be sure.

But, maybe, you didn't notice,Michael, but you are answering someone's concern from Nov 2009; six years ago. I bet they don't have the car anymore!

Actually it was 2007 but I only joined the forum to see if there was a remedy for an annoying warning, and I'm sure there are other CURRENT owners with same problem. Your comment was irrelevant and a bit irritating and a bad start to my joining the forum.

Default ABS fail light

Error lights came on and stayed on. Using ICARSOFT V2 diagnostics tool while wifey drove, all sensors appear to be correctly reading wheel speed. I guess I need a replacement ABS module.

Well known issue with these modules is that the solder on the circuit board fails and causes an abs pump failure DTC code in the diagnostics tool. What code did you get? its a relatively easy but involved (multi-step) problem to solve and you gotta be comfortable with bleeding brakes, handy with a dremel, and ok-ish at soldering.

Well Vinman...it really depends on what level of diagnostic data you require. In some
cases a simple ELM327 with an app you have selected for your phone will do and in other
cases a member may need more specific data to discern a given problem.
