Had same problem with mine. First would not show speed until reached about 25 MPH and then was intermittent. Starts with ABS and Brake Light on and no speed. Checked another website and suggested pulling sensor out of top of rear differential. About $30 part but in hard to reach area. be careful when reinstalling. Do not tighten bolt too fast as this may break the part. Allow it to slowly slide into place. Takes 30-60 minutes to replace. Works fine now.

Replace the speed sensor in the rear end.

Vehicle speed sensor located on top of the rear diff at the brake line clamp a single bolt with a wiring harness. replacement from NAPA comes with a new extension harness. use grease on the terminals before assembly.

It can be several things the ABS modulator, wheel sensors... I would bring it to the dealer and have them diagnose it, they will then retrieve the Abs DTC that your car is giving and pinpoint the problem, this will probably be cheaper than guessing and hoping replacing things will fix the problem!

SOURCE: ABS LIGHT AND BRAKE LIGHT STAY ILLUMINATED

i currently own 2 of these trucks, in total ive had 6 of them .. i know i must like abuse right..lol. on your cruise not working. try this the big flat panel on your dash under the steering wheel. remove it.now this is assuming you have a tilt unit. money bets you do. but anyways the main feed wire i think its called D3 goes out to the fuse box as well as many other wires and a very fine i think again green wire. the problem is that over time using the tilt under normal circumstances those wires start to break. the D3 goes right to the key switch. if that breaks while out on the road. you have 4200 pound paper weight. good place to start. as for your brake light and abs most likley its the abs card or trigger that is located on the center of the rear axle housing. alot of times just replacing the card. if it comes back in a week then its probobly the trigger. not that its broke. this thing goes thru the housing and reads the teeth on the ring gear. and any little wear or a slight chip and they dont read right.. i quit fixing this problem on mine.truth is this thing is the second most delicate thing on the truck... the junk transmissions are the first.. sorry had to say it
