Open the file in a hex editor. Look for the mileage. Example:
Many office printers (HP, Samsung, Xerox) use EEPROM + battery to store toner/fuser page counts. battery+eeprom+works+327+full+free

Before writing anything, read the EEPROM and save three copies. If you brick the cluster, you can revert. battery+eeprom+works+327+full+free
Most people think a low car battery only affects starting. In reality, a dying or disconnected battery creates voltage spikes and sudden power loss. For any microprocessor-based system (including the Works 327 scan tool and vehicle ECUs), this is catastrophic. When voltage drops below 9V during a write operation, the data being saved to memory gets corrupted.
