Is it the BCM Code U1000 and B2610?

I'd chase the B2610 circuit and the BCM inputs first. U1000 is sometimes the result of a communication problem rather than identification of the failed component. So I have seen the DDM, (drivers door module) go out and cause this issue. I would check there first. Also, can I ask how the interior lights have been operating, do they work?
