Default Dash or ECBM Issues

Hi all,

My 2004 Vette dash has gone crazy.

Two of my gauges are not working: Volt & RPM. Upon starting, the needles go all the way to the right but then come all the way back to the left. I am receiving a "Low Voltage" light, which is not true since I put a meter under the hood and tested battery and Alternator.

Also, since I have to pass emissions, the emissions guy told me I have "check engine" light on as well, but it is not on in the dash.

My mechanic says I will need a Level 2 (?) diagnostic that only GM can do. I really hate to give all my Christmas Money to GM so I am soliciting help here first.

Thoughts?
