CM Dash lights flickering, DIC erratic battery reading
My Radio and climate control lights are flickering while I'm driving, and the DIC battery reading is fluctuating between 13.0 and 14.1 volts. The codes I'm getting are, U1160H, B2282H, B2284H,U1064H, B2283H, B2285H and U1064H. Any idea what the problem might be?

Battery is a less then two year old Exide Orbital. I just tightened the battery terminals, and it seems to have fixed it!
Could it be that simple?

Yes, if they are not torqued to 11 ft lbs,
they could create the concern.

Like c4c5 says, these cars have more various computer modules & computing power than the Apollo orbiters did. They like a diet of good steady reliable voltage.

Yes, a loose battery connection can cause some minor or major glitches. I have a 99
coupe that I bought in March. I replaced the battery with a top of the line Sears gel
battery a week after I had it. For over 3 months, I wondered why my radio lights would
flicker at idle and why I could not turn on my headlights with the engine running. I'm
thinking about some expensive repairs, the alternator and the multi-function switch.
I did some research, bought it back to Sears and they tighten the negative terminal
a quarter turn and surprise ... it solved both problems.

Don't assume just because a battery is new or in good shape that the terminals are
tight enough. The C5 needs good grounds and a good juice.
