DESCRIPTION AND OPERATION

Column Electronic Steering Lock
With the ignition switch located in the centre console, a conventional steering lock mechanism cannot be used. An 
electronic system was designed which comprises an ignition switch assembly with a position switch and anti-rotational 
lock and a steering column assembly locking unit with integrated steering lock ECU.

The upper steering column assembly houses the column lock mechanism and ECU. The components are assembled 
with non-removable pins and is therefore non-serviceable. Failure of any steering lock components will require 
replacement of the upper steering column assembly.
