B8. Identify electronic modules, security systems, radios, and other accessories that require reinitialization or code entry after reconnecting vehicle battery.

.  Identify electronic modules, security systems, radios, and other accessories that                            require re initialization or code entry after reconnecting vehicle battery. I have accomplished this task by reading about it in the book. Also I feel that I have accomplished this by installing a battery memory saver in the Ford Expedition prior to performing a parasitic draw test. Usually the only two things that require a re initiialization code are factory stereos and anti theft systems.
