ABS light sporadic

[zonk3939]

My ABS light on my 99 Silverado came on the other day for the first time.I didnt apply the brakes or anything,it just cam on while driving down the expressway.I stopped at a store,and when I restarted the truck,the light didnt come back on.

Today,the light cam on in almost the exact same spot on the highway it did before,and went out again after turning the truck off.Sounds weird,but any ideas?

have it scanned for codes probably a wheel speed sensor going bad , light resets with ignition and dosn't come on till problem occures again.

Zonk,
You find out the fix on this?? My 99 does the same except the parking brake light comes on too!
I'd be interested to know what you found.

Thanks!
