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.
