Steering Lock
The steering column lock comprises a locking motor, locking bolt and a safety release solenoid actuator. See Fig 1. The actuator is required to hold the locking bolt in the unlocked position in the event of power loss during operation. The locking motor drives a cam which moves the locking bolt into and out of engagement with the locking sleeve on the steering column. The locking motor is fitted with a Hall effect sensor which informs the steering lock ECU of the position (locked/unlocked) of the steering lock mechanism.
