I get this on occasion when I move the drivers seat back/forward. The airbag cables run directly under the drivers seat and there is a clip.
Give that a wiggle and turn the ignition off/on. May take a few tries but it usually does the trick on my MY2013 Civic. It’s a soft code as it clears once ok, but the ignition does need to be turned off fully.
I really ought to disconnect it and spray some contact cleaner in.
