MERCEDES IMMOBILIZER EMULATOR

  Project designed a long time ago, certainly contains errors, but tested and working properly in a lot cars from many years.

  This MB Immobiliser Emulator supports Mercedes Sprinter, Vito, ML, A-Class cars with CR1 and CR2 Engine Control Unit.


 MERCEDES IMMOBILIZER EMULATOR - PCB LAYOUT - SCHEMATIC - CR1, CR2
         Sprinter 2.2CDi, 2.7CDi, 5-socket ECU
        ● ML 2.7CDi, 5-socket ECU
         Vito 2.2 Cdi, 5-socket ECU
         A-class 1.7 Cdi, 5-socket ECU
        ● EDC, 1-socket ECU


 
  Schematic diagram is identical for CR1 and CR2. The differences are only in frequency of crystal oscillator and content of uC.
  For MB Immo Emulator CR1 frequency of crystal oscillator is 8MHz, for CR2 frequency of crystal oscillator is 16MHz.
  Schematic circuit diagram is simple and does not need any guide. All electronics components are standard and available.

MERCEDES IMMOBILIZER EMULATOR SCHEMATIC + DUMP

 This ( and all similar ) MB ImmoEmulator work correctly only with edited eeprom in Engine Control Unit.

 In CR2 ECU most often occurs 95P08 /  5P08C3 / 35P08 eeprom. 
 In addresses from $1D0 to $2D0 in place of original values shall to edit and insert the following data :

 or simple copy / paste values from $1D0 to $2D0 from this file.

 CR1 ECU with 24C04 eeprom. 

 In addresses from $1EE to $1F9 in place of original values shall to edit and insert the following data :

 CR1 ECU with 24C02 / B58 eeprom. 

 In addresses from $38 to $39 in place of original values shall to edit and insert data : 2A 4E
 and in addresses from $3F to $42 in place of original values shall to edit and insert data : 9C D4 13 56

This project is many time successfully used in recent years with Sprinter, Vito, ML and others Mercedes vehicles.
Exact instructions about connections MB ImmoEmulator to ECU are available on a lot of websites. So, I will not include it here.
