    I have a 2006 Chevy Silverado 2500HD. The ABS light stays on while operating the truck. The strange part is it does not register a code in the computer system. Before I changed the brakes it had a code for the passenger side sensor, so I changed it while doing the brakes. Now the ABS light stays on, but no codes come up.

    mine came on (with no codes) after i stripped out the speed sensor on the transfer case. I then bought a new one and installed it and the light has stayed on ever since but everything works. Not sure if it is related or one of the front ABS sensors is actually bad. One would think if the code tells you to replace a certain side it would fix it...

    With the truck running unplug the master cylinder, shut the truck off and plug it back in. Then start the truck again. See if it resets.

    put it on a good scanner, not a code reader, and see what the live readings are

    Sounds like you need to do a front hub(s) to me. Pretty easy shadetree mechanic job. There is a little sensor on the front hub assembly. That is most likely your issue.
