STEERING LOCK SYSTEM

FUNCTION

1. Steering Lock System

   
   

   1. The steering lock system is integrated in the steering lock ECU, and the ECU controls the lock bar operation in the steering lock actuator assembly through the control of lock/unlock motor.

   2. The steering lock ECU detects the position (lock/unlock) of the lock bar and transmits this information to the power management control ECU and certification ECU.

   3. In this system, the certification ECU determines whether to lock or unlock the steering based on communication with the power management control ECU. Then, the certification ECU sends lock or unlock command signals, the steering lock ECU through the ID code box. Upon receiving the signals to the steering lock ECU operates the lock/unlock motor to lock or unlock the steering.

      Tech Tips

      It is not possible to replace only the steering lock ECU in the steering lock actuator assembly. Therefore, if the ECU malfunctions, the entire steering lock actuator assembly must be replaced.
