ok as some of you may know Ive been having gauge issues if you seen the video along with car not starting so had to hook up a ghetto push start button. Well my buddy hooked up his snap on computer at his shop and here are the codes we found.
U2100: Control area network(CAN) Bus Communication.
U2105: Lost Communication with Engine Control Module(ECM)
U2111: Steering wheel controls(aftermarket radio)
So I also guess my check engine light is suppose to be on but we cant even turn it on with the computer. So going to put in my stock radio hopefully that works. If not Looks like I have A LOT of work ahead of me =(
heres a video of the gauges
2005 Cobalt SS gauges going crazy. - YouTube

I have that problem too but it comes and goes. Havn't had the malfunction in some time.
And what you show in your video is EXACTLY what mine does. Thanks for captureing the video of it. I noticed that when I stop
it resets and starts working. I'm glad I have interceptors, because they continue to work and I can set them for speed/rpm and
still have woking indications.

Also note: Your radio was working, I could hear it going. Mine worked too, so did my power windows and door locks. Ill try to look into it abit more ill let everyone know if i find something.

Same here gauges come and go wont happen for months then boom there it is. If it does it when i turn the car on i lose power steering(got the recall fixed)but if it happens while driving im fine. and yes my radio does work but we are losing connecton somewhere and my buddy said it might be at the radio since thats where all the wires and security go
