Hey guys, I've been dealing with the same problem for a few months now. My abs light come on with the traction control and service 4wd light all at the same time. I've read people with similar problem and have tried just about all of them, might have missed a sensor but I figured I would put some feelers out there and see if anyone else has had better luck.
So far I have changed both abs speed sensors in the rear, changed the speed sensor on the transmission, put new tires on the truck, and installed a new battery. Also put 2 new o2 sensors in since it seemed to begin after I pulled my y pipe and forgot to disconnect my battery.
It looks like you can test sensors with a ohm reader to check resistance so I think I'll do that on the last few sensors but if anybody has any input or better luck I'd love to know.
Thanks guys
