Steering Column Control Module (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
- Wiper washer switch
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.
