Random U0422 code with blinking hold light. Car drives fine

[Rest0redGe0Duck]

This is the second time this has happened. "Invalid Data received from the body control module." I was driving normally and the hold light started flashing. Everything on the car works great. The automatic transmission Shifts normally, great power. Happened for the first time about 5 months ago, I disconnected the battery overnight and it stayed clear until last night. The body control module seems to be working fine. All body functions are functional. I'm out of clues and ideas. I would greatly appreciate any input anybody might have. I try to stay on top of my maintenance and I don't drive the car hard at all. but if this is some kind of phantom within the car, I might have to get used to that flashing light.

I have heard of bcm modules developing a poor connection where the harness plugs in. Might be worth pulling it off, spraying both ends out well, inspecting none of the pins to be bent, and putting some dielectric grease on one end before plugging it back in. Any moisture accumulated between the connections can do funny things.
