Steering Lock ECU (Steering Lock Actuator or Upper Bracket Assembly)
|
- 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.
- The codes (L codes) of the ID code box (immobiliser
code ECU) and steering lock match.
- The codes (S codes) of the ID code box (immobiliser
code ECU) and certification ECU (smart key ECU assembly)
match.
- The certification ECU (smart key ECU assembly) and key
ID codes match.
|
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 (steering lock actuator
or upper bracket assembly) to turn the power on, start the engine
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 immobiliser set and unset commands from the certification ECU
(smart key ECU assembly) via LIN communication and sends them to the ECM.
