U0200 Lost Communication With Door Control Module B (Passenger) Low
The U0200 code means other modules in the vehicle stopped receiving messages from door control module B on the passenger side. The usual effect is a power window or lock on that door that does not work. The cause is often power, ground, a connector or a weak battery rather than the door module itself.
