STEERING

DESCRIPTION AND OPERATION

57-15

The steering column lock comprises a locking motor, locking bolt and a safety release solenoid actuator. 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.
