Hey guys, here are the codes that came up today..what do you think is causing this??

10-PCM, 1 code, P1416 HC

A0-LDCM, 3 codes, B2282 H, B2284 H, U1064 H

A1-RDCM, 3 codes, B2283 H, B2285 H, U1064 H

BO-RFA, 1 code, U1064 H

I installed a new batter about 3 weeks ago, but the light come on today. What do you think is causing this??

I just checked the battery and it was not an ACDelco battery. It also seems like the battery tray has more room now, meaning, the battery cables are tight and i am able to move the battery around in the trey..Does this mean that the battery that is in there now is too small?? could this be the problem? The battery is Auto Craft..not ACDelco.

Those are all history codes clear them and see if they come back

See this thread for more on P1416 HC
Sounds like you have an O2 sensor going bad...

P1416 indicates bank 2 or the right (passenger side),
And yes, chances are it's the right bank check valve for the Air Injection Reaction (AIR) system. They tend to burn out after a header install.

The rightside check valve requires removal of the intake manifold to gain access to, unlike the easy to get to left side check valve.

the P1416 is an "AIR system bank" error
and thE u1064 is an "Loss of communication with DCM" error.

The rest of the codes are "Battery #1/#2 fault DCM -right/left"

To be more explicit, with the possible exception of the P1416, you can safely ignore all the other codes. You can in fact ignore the P1416 as well, unless you see the Check Engine light.
