The steering column has a shaft and an adjustment mechanism contained in a frame assembly attached to the instrument panel cross beam. Shrouds cover the upper column where it extends from the Instrument Cluster (IC). The steering column adjustments provides tilt and reach adjustment using two Direct Current (DC) electric motors each fitted to a gearbox. One motor is for tilt movement and one motor is for reach movement. Operation of the motor is controlled by the Body Control Module/Gateway Module (BCM/GWM) assembly and a four way joystick type switch located in the lower shroud.
Electric steering column calibration is defined by running each motor to the end-stops of the steering column. After calibration the system knows the position by counting the signals generated by Hall-effect sensors located in each column adjustment motor.
The steering column features service position. For additional information, Refer to: STEERING COLUMN SERVICE POSITION
Upper and lower shrouds cover that part of the upper column not concealed by the instrument panel.
