Steering Column

The steering column spindle is part of the steering column jacket assembly, that is installed in the swing bracket. An electric motor on the swing bracket drives the steering column jacket assembly axially within the swing bracket. This provides the reach adjustment of the steering column.

The swing bracket is attached to the inner bracket with 2 pivot pins at the front and 2 threaded spindles at the rear. A second electric motor on the swing bracket drives the spindles to raise and lower the rear of the swing bracket, relative to the inner bracket. This provides the tilt adjustment of the steering column.

The inner bracket is located on rails in an outer bracket, which is attached to the cross-car beam. The inner and outer brackets are locked together by an energy management plate, which is attached to both brackets with screws. In a serious impact, the inner bracket progressively moves forwards on the rails in the outer bracket. This provides to prevent excessive force causing injury as the driver strikes the airbag, The movement is controlled by sections of the energy management plate that peel back in a controlled manner. This provides to absorb energy and to allow the steering wheel to move with the driver.

The Steering Wheel Module (SWM) and Clockspring (CLKSPG) assembly is attached to the top of the steering column jacket by 2 screws. The assembly includes the multifunction switches for the exterior lighting and for the windshield wipers and washers.

Upper and lower cowls cover that part of the steering column not concealed by the instrument panel. The steering column adjustment switch, for control of the tilt and reach adjustment motors, is installed in the right side of the lower cowl. The lower cowl may also contain an Immobilizer Antenna Unit (IAU) for the Passive Entry Passive Start (PEPS) system. For additional information, Refer to: ANTI-THEFT - PASSIVE .
