CIRCUIT DESCRIPTION
| Component | Outline | |
|---|---|---|
| Steering Lock Actuator Assembly | Steering Lock ECU | The steering is locked and unlocked by communicating with the certification ECU (smart key ECU assembly) and ID code box (immobiliser code ECU) via LIN communication. When the following conditions are met, the steering can be unlocked.
|
| Certification ECU (Smart Key ECU Assembly) | The ID code of the key the user is carrying is sent to the door control receiver. The certification ECU (smart key ECU assembly) compares the key ID code it receives from the door control receiver with its own ID code. If they match, the certification ECU (smart key ECU assembly) permits the steering lock ECU to turn the power on, start the hybrid control system and unlock and lock the steering. Outputs a command to supply power to the steering lock motor based on the power source mode, shift position and vehicle speed signal. |
|
| ID Code Box (Immobiliser Code ECU) | Receives steering unlock or engine immobiliser unset signals from the certification ECU (smart key ECU assembly), certifies them, and transmits each unset signal to the steering lock ECU. | |
