Locate 93C86 chip on CPU
Desolder chip and read 93C86 data via ECU programmer,i.e XPROG Programmer, then save eeprom data
Then select Open Dump File, upload 93c86 eeprom data just read
Wait some minutes to upload file. Then Car Key Programmer TM100 will display key information, key number, key position etc.

Reinstall ECM back to car, now you can start car with the ID48 chip.
