U121E DODGE Meaning

The Steering Column Control Module (SCCM) is located near the top of the Steering Column underneath the Steering Wheel. The SCCM includes the Clockspring, the Multi-Function Switch and a Local Interconnect Network (LIN)/Controller Area Network (CAN) C Gateway. LIN Bus messages received by the LIN/CAN C Gateway are broadcast over the CAN C Bus to the appropriate modules.
The Right Steering Wheel Switch (Speed Control Switch) communicates with the Steering Column Control Module (SCCM) through a dedicated LIN Bus. When the SCCM receives a LIN Bus message from the Right Steering Wheel Switch, the SCCM will send a message over the CAN C Bus to the appropriate modules.
The Diagnostic Trouble Code (DTC) sets if the Steering Column Control Module (SCCM) does not detect any communication with the Right Steering Wheel Switch (Speed Control) for greater than five seconds.
