Steering Column Switches Overview

The steering column switches are located on and around the steering column. This enables the driver to control various vehicle functions and remain focused on driving. Depending on vehicle options, the steering column switches consist of:

• Multifunction switch - mounted on the left side of the SCCM and can be serviced separately. The SCCM is a module that requires Programmable Module Installation (PMI).
• Steering wheel switches - mounted on the front of the steering wheel and can be serviced separately from the steering wheel.
• Wiper and washer switch - mounted on the right side of the SCCM and can be serviced separately.

The steering column switches interface with other modules and components on the vehicle through the SCCM, which communicates on the High Speed Controller Area Network 2 (HS2-CAN).
