I have a traction control failure and a host of codes from the scanner. I already changed out the 4x4 button console and tested all buttons. The truck 4 wheel buttons all work and the truck will switch fine between high and low. The traction control button works as wekl. I also have no brake light or any other issues. Also replaced the brake switch. Switch my battery and terminals. Checked all the fuses. Here are my codes:
Co136
B0010
U1064
U1305
U1041
U1017

Cleared all codes and all return instantly. Anyone have any ideas? Again all lights work and no other issues with the truck. Probably have 24 hours of troubleshooting so far.

One more update: I do not have an abs light or check engine light or codes.

C0136 - faulty brake booster (electric on the H3).
B0010 - open circuit in the reverse lights. Check the harness by the rear bumper, often wires get chafed here. Also look for rodent bite marks.
U1064 - no communication between the numerous brains (PCM-TCM-BCM).
U1305 - hi/lo voltage on com circuit.
U1041 - no communication to/from brake modulator valve.
U1017 - no communication to/from PCM.

Your Hummer is basically having an epileptic seizure. Wild electrical pulses coming & going. What this is all saying is that you have some wiring/communication issues. Most likely a bad ground, corroded plug, chafed wire, or rodent damage. It could also be low voltage. Anytime you get lit up with numerous random codes, its almost always caused by a central voltage issue. Individual parts on numerous systems rarely fail in unison. So don't just start replacing parts & sensors. That usually results in nothing but a flat wallet. Its probably something simple and cheap.

I would start with the battery connections (make sure the ground is good & tight and connected to the body & frame). Next, take a look under the fuse box (under the hood) and see if there is a rodent nest. Mice just love it under there, and I find piss and poo under the fuse box on every third H3 that rolls in here! Inspect the wiring on all the devices above. Also check the plugs at the PCM, TCM, and BCM...the latter often flooded by clogged sunroof drains. Look for wet carpet padding on the passenger floor...if so, I would highly suspect the BCM has corroded to the point where it is freaking out. BCMs are not cheap! Start with the other stuff first.
