ABS light on after getting up to speed

[TexasAggie]

ABS light came on this weekend and stays on until the truck is turned off. Comes back on after passing a certain speed (stays off when driving through the parking lot, but comes on when I hit the road).

I'm thinking wheel speed sensor. How do I verify, and how do I identify which one it is?

UPDATE:. this is on a '99 K2500 Suburban.

Chinese back on after passing a certain speed....

I don't know what the Chinese have to do with your problem, but I would measure your wheel sensors at their respective connectors. Off the top of my head, the resistance should be somewhere around 2000 Ohms, but don't quote me on that.

I'm guessing auto correct twisted the words lol
