the immobilizer code in the engine control module (ECM) is incorrect i. e. the code does not correspond to the code stored in the central electronic module (CEM)
the engine control module (ECM) is not programmed and has no immobilizer code
the immobilizer code in the central electronic module (CEM) is incorrect
the central electronic module (CEM) is not programmed and has no immobilizer code
the engine control module (ECM) is damaged
the central electronic module (CEM) is damaged.
