The body control module controls about everything inside truck and outside sometimes. It' deals with lights, radio, cameras etc. It may be a connection problem or what is called a can bus which several modules are connected on same line and if one goes out it cause a aproblem. It can be a shorted wire, water, etc. To cause it to go out. Or even a surge of electricity that is to high in voltage.
