Description And Operation: Overview
The steering column comprises the upper column assembly, the intermediate shaft and the lower collapsible shaft. The three components are positively connected together to pass driver rotary input from the steering wheel to a linear output of the steering rack.
The upper steering column assembly is electronically adjustable for steering wheel reach and rake and is controlled by the CJB (central junction box). The upper steering column assembly also provides the location for the electronic steering lock mechanism and the steering angle sensor.
