Either the traction control fuse is bad or the traction control relay is bad. Easy fix is to yank the RCM and send it to DJ for rebuild, he will test it in one of his Crossfires before shipping it back.

You can try checking the fuses but it's never the fuse. Take the cover off the module box (under hood, passenger side) and yank all fuses from the RCM except the 40 amp fuse and verify they are good.
If they are, then remove the RCM and send it to DJ (or order a new RCM and still send the old one for rebuild so you have a spare), it comes out without tools.
DO NOT yank on the wires, grasp the connectors and rock them out gently.
