2.1.2 “Dump Tool”
By using this special function it is possible to calculate odometer values, display PIN codes, etc..
This application needs the EEPROM dump from the corresponding control unit. After the dump is
loaded, some modifications will be made and you need to store the resulting dump as a new file,
which you can program with a special programmer into the device that the dump is from. The
dump tool receives as input a dump file from the corresponding unit (input dump is loaded with
the “Load dump” button). The dump file can be read either via OBDII but also with a programmer
(especially for units where reading via OBDII is not possible). As output the dump tool displays
some data extracted from the input file and/or makes some modifications to the input data. If
modifications were made (for some sub-functions there are no modifications made, only data are
visualized) the user has to write the modified dump to the desired file (with the “Save dump”
button), and then this modified dump should be saved back to the device via OBDII or with a
programmer. If data are read/written with a programmer the user must make sure that the proper
byte order is used. Because most of the programmers are reading the data on 16bit words, the
byte order in the dump depends on the used programmer – some programmers produce dumps
starting with the least significant byte, and some produce dumps starting with the most significant
byte. This means that for the same unit two different programmers can produce different dumps.
For that purpose a button “Swap bytes” is provided. This buttons changes alternatively the byte
order into the dump. So, if after loading the dump file into the dump tool data cannot be extracted
or modified, please try to swap the bytes to get a correct result.
