Notes
Upon receiving this PGN, the DST will restore part of user EEPROM memory to its factory default state.
The Options field (field 5) specifies whether all of user EEPROM memory (except the user Unique Number) is to be restored (value 0x0), or only a subset of EEPROM memory
is to be restored.
Note that this PGN requires Access Level 1, even when resetting the Unique Number to its factory default value (option 0x4). The proprietary PGN to change the Unique
Number to a value other than the factory default value, which is described in another document, requires Access Level 2.
In order for this received PGN to be recognized by the DST, the Manufacturer Code, Industry Group, and Proprietary ID (fields 1, 3, and 4) must match the values shown.
Although this is a fast-packet message, the version with this PID fits into a single CAN frame.
