На бензинках штатная имма "блокирует мозги" - нет классического реле размыкания или еще чего. ЭБУ видит отсутствие ответа от иммы и тушит мотор.
Если что - обманка стоит порядка $20, можно вживить непосредственно в ЭБУ (что я и сделал другу на ABV)
На дизелях, согласно Эльзе, стоит клапан отключения подачи топлива

Function for all vehicles
With the 2nd generation of immobilizer the so-called "Cryptocode" principle has been introduced to improve the anti-theft security.
This "Cryptocode" principle selects a number at random in the immobilizer control unit and transmits it to the "Crypto" transponder in the ignition key.
Each transponder has its own "fixed code". After a predetermined procedure the transponder calculates a new number from the number which was transmitted and the "fixed code".
This new number, the "Cryptocode" is transmitted back to the immobilizer control unit where it is calculated back using the same predetermined procedure.
The result of the back calculation and the initial number selected at random must tally. The key will then be recognised as an authorised key.
After the key has been recognised as being authorized a "variable code" will be transmitted to the engine control unit.
The "variable code" will be randomly selected in the engine control unit after each time the engine is started and stored in both control units.
If the "variable code" in the immobilizer and engine control units tally, the vehicle can be put into operation.
