SYSTEM DESCRIPTION
1. DESCRIPTION
(a) The steering lock system locks/unlocks the steering when 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 power management control ECU.
2. FUNCTIONS OF COMPONENTS
(a) The steering lock ECU (steering lock actuator assembly) controls the system based on information from the following components.
