Default Something wrong with my car. Weird DTCs. Please help!!!

My buddy has HP Tuners and we scanned it to see why I am getting SES lights even though the car has been tuned for the mods. When we scan it, the following codes come up (not exact description, but you'll know what I am talking about), and we can't clear them, they just stay there:

U1000 - Class 2 Communication Malfunction
U1016 - Loss of Class 2 Communication

There were more, but it was referencing [HUD], [BRAKE], & [RESTRAINT], and all of the codes started out with 1000 & 1016. Is this a BCM issue?

Clean the PCM connectors clear the codes and see if they pop back up.

Tried that, SES went away for about a day, and now it is back. The weird thing is, they are set on "No error reported" via HP Tuners, yet they are still throwing a SES light.

they are just bcm & communication codes that I believe are set when doing a reflash, generally nothing to be worried about.
