Ford GEM ECU Synchro v1.1

Description

Ford Mondeo 2008+, Galaxy 2008+, S-max 2008+ transponder key programming and used (second-hand) SID206 ECU synchronization utility.

How does immobilizer work on Ford Mondeo 2008+, Galaxy 2008+, S-max 2008+:

Immobilizer data (PATS) on these cars are stored in the Intelligent power distribution module (GEM) located in the passenger compartment fuse box. GEM receives a transponder key signal from the immobilizer coil and if the key data is equal to the car, GEM sends a synchronization signal to the motor ECU. If the transponder key is stored in GEM and synchronization data GEM-ECU is correct, GEM permits to start the engine.

How to use this program:

If the car transponder key is lost: remove GEM (Intelligent power distribution module) from the car. Open and locate 25320 EEPROM. Read (with CarProg you can read in-circuit), save file and open with “Open GEM EEPROM”. The program will show you transponder data. Write this data to EH2 or TPX2 transponder with any transponder programmer (like RW4, Codereader or Zedbull).

If motor ECU is defective/lost:

Remove GEM (Intelligent power distribution module) from the car. Open and locate 25320 EEPROM. Read (with CarProg you can read in-circuit), save file and open with “Open GEM EEPROM”. Open SID206 ECU and read 95320 EEPROM. Open the file with “Open ECU EEPROM” button. Now transfer synchronization data from GEM to motor ECU. Save the ECU file and write it back to SID206.
