Getting to the Ford/Mazda "Special Functions": Memory Read/Write and Key Learning

The Special Functions are the Abrites-specific functions, the ones other diagnostic tools do not have: memory read/write (EEPROM), mileage recalibration, key learning, Custom Request and Dump Tool. Here is how to get to them and how to use Memory Read/Write.

Procedure

1. Connect the AVDI, start the software, select the vehicle context and then the control unit you want to work on.
2. Look at the bottom right corner of the main screen: that is where the list of "Special Functions" available for the selected module sits.
3. Launch the function you want by double-clicking the entry, or by selecting it and pressing the "Open" button to the right of the list.
4. For memory reading select "Memory Read / Write": always read the memory FIRST and save the dump to disk - it is your only backup if the write does not go through.
5. Store the file you read in a folder tagged with the plate/VIN and the date before you change a single byte; only then go ahead with the write.
6. The functions available depend on the software version you bought: if an entry does not appear in the Special Functions list, that function is not included in your licence.
7. This same list is also where you reach "Key Learning", the PATS functions, the OUT/IN code calculator, the VID block and the "Dump Tool".
