Mitsubishi Dump Tool: mileage calculation and PIN reading from an EEPROM dump ("Swap bytes" function)

The "Dump Tool" works on the EEPROM dump of the control unit concerned and lets you calculate odometer values, display PIN codes and more. Some sub-functions only display the data, others modify the dump, which then has to be written back into the module.

Procedure

1. Obtain the EEPROM dump of the control unit concerned. You can read it over OBDII or with a programmer, which is the only option for modules that cannot be read over OBDII.
2. Always keep an untouched copy of the original dump before making any changes: it is the only way back if something goes wrong.
3. Start "ABRITES diagnostics for MITSUBISHI", open the "Special Functions" tab and select "Dump Tool" by double-clicking, or by selecting it and pressing "Open".
4. Load the dump file with the "Load dump" button.
5. If after loading the data is not extracted or cannot be edited, press the "Swap bytes" button: it toggles the byte order in the dump and in nearly every case solves the read problem caused by the programmer used.
6. Select the sub-function you need (odometer value calculation, PIN code display, etc.). Some sub-functions only display the data extracted from the file, without modifying it.
7. If the sub-function has modified the data, save the result to a new file with the "Save dump" button (do not overwrite the original dump).
8. Write the modified dump back into the source device, over OBDII or with the programmer, using the same byte order the dump was read with.
9. Refit the module, connect the AVDI and check the result in diagnostics: verify the displayed value and read/clear any faults generated during the job.
