Just quit working yesterday

Back rt wheel bouncing can't go more then couple miles per hr/ possible problems problems air bag shocks

When I drive over bumps or rap the steering wheel the system acts like there's an open door somewhere and the seat belt light comes then off with the door ajar light and the wiper blades wont stop wiping twice, the rear wiper does not respond and the controls for the front wipers are unresponsive too

Replaced right rear brake caliper and epb motor replaced abs module had reconfigured at dealership but code says missing calibration
