THEFT DETERRENT / KEYLESS ENTRY: ENGINE Immobilizer SYSTEM (w/ Smart Key System): SYSTEM DESCRIPTION

SYSTEM DESCRIPTION

1. ENGINE Immobilizer SYSTEM DESCRIPTION
The Immobilizer system is a theft deterrent system that determines whether to disable starting of the SFI system based on a comparison of the key ID code and the vehicle pre-registered code. The Immobilizer system compares the vehicle certification ECU (smart key ECU assembly) pre-registered ID code with the ID of the key-embedded transponder chip. If the ID codes do not match, the Immobilizer system is activated and the SFI system cannot be started. The certification ECU (smart key ECU assembly) manages communication with the ECM, power management control ECU and steering lock ECU (steering lock actuator assembly). When the ID codes of the transponder chip and certification ECU (smart key ECU assembly) match, the certification ECU (smart key ECU assembly) authorizes the SFI system to start.
