I have a 2013 Unlimited Sport that I just purchased. Any ideas as to why my anti-skid warning light would be lighting up regardless of whether I have it turned on or off. It doesn’t seem to drive any differently if it does come on. The Jeep does have aftermarket wheels and tires on it so I thought it could be a wheel speed sensor issue but even if that is the case I don’t know what to do to fix it. Thanks for any advice and have a great day!

Can you scan for any codes?

I went to OReilys and the report gave a code of P501 - Vehicle Speed Sensor 1 Performance. I just had the rear slip differential rebuilt and both rear wheel bearings replaced as well. The warning light came on a few times before this but today was the first time it came on and stayed on.
 
I've heard of speed sensor connectors coming loose or making poor contact, resulting in error codes as if the sensors are failing.

If it were me, I would give a thorough inspection of the sensor connections (probably even adding dielectric grease as a barrier to future corrosion & faulty contacts) and then go from there.

I will check that. How much can it be off if it is?


Going to do that this evening.

Doesn't take much. There's a road I travel regularly that has an excessive amount of crowning. You have to keep a little pressure on the wheel or you will drift over. That's enough to trigger it.
