Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Steering Column Control Module (SCCM)
| Refer to COMPONENT INDEX . |
The wiper (left) multifunction switch of the SCCM uses resistor multiplexing to control the many functions and features it provides using a minimal number of hardwired circuits. The switch receives clean grounds from the BCM, then provides resistor multiplexed return outputs to the BCM to indicate the selected switch positions. The BCM then sends hardwired control outputs as well as electronic switch status messages over the CAN-C data bus to other electronic modules in the vehicle.
