Automatic Determination

In order to determine which EPROM needs to be installed there is a special procedure that is executed as part of the "Exchange EPROM" process. The procedure will "automatically" determine the correct replacement EPROM or control module part number, based on the "Basic part number" and "Programmed part number" stored on the installed EPROM, if the EPROM is not damaged.

The procedure is run automatically if "YES" is selected for the answer to the question Is old EPROM still installed.

During the automatic determination process the tester compares the part numbers stored in the EPROM of the currently installed DME control module with a list of possible replacement part numbers contained in the program of the tester.

The comparison is done to determine if the tester can "recommend" a replacement EPROM or control module part number.
