Ford Transit/Tourneo Connect v1.1

Ford Transit/Tourneo Connect 2005-2010 immobilizer system repair, transponder key programming and used (second-hand) SID206 ECU synchronization utillity.

How immobiliser works on Ford Transit Connect 2005-2010:

Immobiliser data (PATS) on these cars are stored in the instrument cluster(IC) HC12 processor. Instrument cluster receive transponder key signal from immobiliser coil and if key data is equal to car, IC send synchronisation signal to motor ECU. If transponder key is stored in IC and synchronization data IC-ECU is correct, ECU permit to start the engine.

How to use this program:

If car transponder key is lost: read with CarProg instrument cluster EEPROM by OBDII (or you can remove IC from car and read HC12 processor EEPROM with any programmer (like CarProg, XPROG OR UPA), save file and open it with "Open IC  dump". Program will show you transponder data. Write this data to EH2 or TPX2 transponder with any transponder programmer (like RW4, Codereader or Zedbull).

If immobilizer lamp is ON, motor ECU is defective/lost: read with CarProg instrument cluster EEPROM by OBDII (or you can remove IC from car and read HC12 processor EEPROM with any programmer (like CarProg, XPROG OR UPA), save file and  open it with "Open IC dump". Open SID206 ECU and read 95320 EEPROM (with CarProg you can read in-circuit). Open file with "Open ECU EEPROM" button. Now transfer synchronization data from IC to motor ECU. Save ECU file and write it back  to SID206.
