SYSTEM DESCRIPTION
1. ENGINE IMMOBILISER SYSTEM DESCRIPTION
The immobiliser 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 immobiliser 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 immobiliser 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.
2. FUNCTION OF MAIN COMPONENTS

Outline |
---|---|
Transponder key coil/amplifier (built into the engine switch) |
|
Key |
Receives the signals from the oscillators and returns the ID code to the door control receiver. |
Steering lock ECU (steering lock actuator assembly) |
Receives the steering unlock/lock signal from the certification ECU (smart key ECU assembly), and activates the steering lock motor. |
Power management control ECU |
|
Certification ECU (smart key ECU assembly) |
|
ECM |
Receives the signal from the certification ECU (smart key ECU assembly), and performs engine ignition and injection. |
Indoor electrical key oscillator
|
Transmits key detection signals within the detection area in the vehicle cabin upon receiving a transmission request signal from the certification ECU (smart key ECU assembly). A certification ECU (smart key ECU assembly) request signal is activated when the key is brought into the vehicle cabin and the engine switch is pushed. |
Door control receiver |
Receives an ID code from the key in the actuation area and transmits it to the certification ECU (smart key ECU assembly). |
Accessory meter assembly
|
Illuminates or flashes. Illumination is controlled by the certification ECU (smart key ECU assembly). |
