of the steering lock assembly, main body ECU, certification ECU and ID code box
D The steering lock ECU is integrated in the steering lock assembly, and it controls the lock bar operation
in the steering lock assembly through the control of the lock / unlock motor

to the main body ECU and certification ECU
