Steering Column Switches

Overview

The steering column switches are located on or around the steering column, giving the driver the ability to control various vehicle functions and remain focused on the task of driving. Depending on vehicle options, the steering column switches consist of the following:

• Multifunction switch — mounted on the left side of the SCCM and can be serviced separately from the SCCM .
• Steering wheel switches — mounted on the front of the steering wheel and can be serviced separately from the steering wheel.
• Steering column control switch — mounted on the left side of the SCCM just below the multifunction switch and can be serviced separately from the SCCM .
• Pedal adjust switch — mounted on the left side of the SCCM just below the multifunction switch and can be serviced separately from the SCCM .

The steering column switches interface with the other modules and components on the vehicle through the SCCM .

Component Description

Multifunction Switch

The multifunction switch is a multiple position switch controlled by a lever. The multifunction switch controls the turn signals, headlamp low/high beam and headlamp dimmer/flash-to-pass, front and rear windshield wiper and washer functions.

For information on the turn signals, headlamp low/high beam and headlamp dimmer/flash-to-pass, refer to Section 417-01 .

For information on the front and rear windshield wipers and washers, refer to Section 501-16 .

Steering Wheel Switches

The steering wheel switches are comprised of 2 switch clusters mounted on each side of the steering wheel facing the driver. Each switch cluster contains 3 rocker switches and a 5-way directional switch pad.

The 5-way directional switch pad on the left switch cluster controls the message center display. Refer to Section 413-01 .

The 3 rocker switches on the left switch cluster control the adaptive or non-adaptive cruise control. Refer to Section 419-03A or Section 419-03B .

The 5-way directional switch pad on the right switch cluster controls the infotainment display. Refer to the appropriate section in Group 415 for the procedure.

The 3 rocker switches on the right switch cluster control the infotainment display. Refer to the appropriate section in Group 415 for the procedure.

SCCM

The SCCM is attached to the steering column, behind the steering wheel. The SCCM receives inputs from the following items:

• Multifunction switch
• Pedal adjust switch
• Steering wheel rotation sensor
• Steering wheel switches

Using the inputs above, the SCCM controls the output directly or transmits the information as messages on either the HS-CAN or the LIN .

The SCCM also provides a “pass-through” circuit path, via the clockspring, for the following components and/or features:

• Driver air bag module
• Horn
• Steering wheel switch illumination

The SCCM monitors all of the inputs it receives and is capable of setting DTCs if a fault is detected.

Pedal Adjust Switch

The pedal adjust switch is a momentary contact switch used to adjust the position of the brake and accelerator pedals. For information on the pedal adjust system, refer to Section 206-06 .

Steering Column Control Switch

The steering column control switch is a momentary contact switch used to adjust the position of the power adjustable steering column. For information on the power adjustable steering column, refer to Section 211-04 .
