DESCRIPTION
The steering lock ECU and steering lock actuator assembly are supplied as a unit.
The steering lock ECU detects the steering lock position through the signals from the lock and unlock position sensors.
The steering lock ECU activates the steering lock motor based on permission signals from the power management control ECU and the certification ECU.
The diagnosis information of the steering lock ECU is transmitted to the Techstream via the certification ECU as the steering lock ECU is not connected to the CAN communication system.
