Default code not in HPT?

I just put a 402 in my camaro and it keeps throwin these codes and there not in HP tuners DTC list, and i dont know what to do to fix them, and i have tryed searching also, they are as follow:

B0026-LF/driver frontal deployment loop open

C0240-Unknow obdii.com said PCM traction control not allowed,whats up with that, y did that just stop working out of the blue?

u1016- loss of class 2 communication with vcm

What do these codes mean and how do i fix them, when i try to clear them they just come right back as soon as i take my finger off the button?
Please help.

Also the camshaft sensor on the ls2 is in the front cover and my plug from my 99 wiring harness wouldnt fit and the wires were diff, they were the same color but the 2 outside wires, the one in the middle was the same color but the 2 outsides were swaped, should i just leave them swaped or mach all the colors up?

they are BCM codes & cannot be edited by hptuners...hptuners just decided to allow you to view the codes since 2.1.12 released about 3 months ago.

There are a lot of reasons you may have gotten those codes. Your best bet would be to find someone with the EFILive scantool to clear them for you.

I'm also interested in this, I'm throwing the same code...U1016 Loss Of Class 2 Communication With VCM. Anyone seen/heard of what this is, what it affects (if anything), and how to correct the problem?
