There should be a one-wire connector taped to the big wire bundle that passes through the firewall near the parking brake pedal. The wire is black with an orange tracer. This is the diagnostic wire for the ABS system, if it is momentarily grounded while the light is on, the ABS system should blink trouble codes on the ABS light. This will give you a better idea of where to look for the problem. If it doesn't blink, check the float switch connection on the master cylinder.

It could be the ring gear sensor at the top of the differential or the M/C reservoir plug as mentioned.
**It also could be that you need to bleed the RABS valve. Which on my truck is located inside the frame rail beneath the drivers seat.**
I can't get a code using EPCNSU2006's method and have come to the conclusion that it must be that my computer is FUBAR'd.

I can't get a code either, and I found the float switch connector was broken when I replaced the master cylinder for an unrelated issue. That cured the light for a while, now it is on and off randomly.

Pure Genius QuadDriver. Hahhaha.
I'm not sure whats up with it. Just to throw it out there, I drove through a ditch. ( I was turning around while wheelin' and didn't notice it. ) Thumped into it really hard and the light turned off.
2 minutes later there was a log in the trail I drove over and the bump turned it back on.
Any new idea's?
