Steering Lock System -- System Description



DESCRIPTION
  1. The steering lock system locks or unlocks the steering lock by activating the steering lock bar with a motor. The steering lock ECU (steering lock actuator assembly) activates the motor based on signals from the certification ECU (smart key ECU assembly) and main body ECU.

  2. A LIN (Local Interconnect Network) is used for communication between different ECUs in this system.


FUNCTIONS OF COMPONENTS
  1. The steering lock ECU (steering lock actuator assembly) controls the system based on information from the following components.

    Item
    Function
    Steering lock ECU (Steering lock actuator assembly)
    1. Consists of a motor, lock bar, lock and unlock position sensors, etc. activated by the steering lock ECU (steering lock actuator assembly).
    2. Included in the steering lock actuator assembly. This ECU activates the steering lock motor based on permission signals from the main body ECU and certification ECU (smart key ECU assembly).
    3. Detects steering lock or unlock information and transmits this information to other ECUs.
    Main body ECU
    Permits the steering lock ECU (steering lock actuator assembly) to supply power to activate the motor. The main body ECU and certification ECU (smart key ECU assembly) permit engine start after receiving an unlock signal from the steering lock ECU (steering lock actuator assembly).
    Certification ECU (Smart key ECU assembly)
    Orders the steering lock ECU (steering lock actuator assembly) to lock/unlock the steering. The main body ECU and certification ECU (smart key ECU assembly) permit engine start after receiving an unlock signal from the steering lock ECU (steering lock actuator assembly).
    IG2 relay
    Controlled by the main body ECU. This ECU sends IG signals to the steering lock ECU (steering lock actuator assembly).
