B3. Maintain or restore electronic memory functions.

Maintain or restore electronic memory functions.  I accomplished this task by hooking up a memory saves in the Ford Expedition in the shop. this was done prior to the parasitic draw lab which required the disconnection of the battery, which without a memory saver would loose all of the computer memories of the car such as preset radio stations, cruise control presets, etc. This memory saver is plugged into the same connector to which a scan tool is connected.
