SCCM Control Unit: Notes

The steering column control module (SCCM) control unit has two CAN interfaces, one to the low-speed CAN bus and one to the high-speed CAN bus. It is used as the interface between the high-speed bus and the low-speed bus to exchange information between the CAN buses. All components of the SCCM, except the ignition key with its RF receiver/transmitter (transponder), are directly connected to the SCCM control unit (plug connection) and therefore require no additional wiring.
