Body Control System Description and Operation (Steering Column Control Module): SCCM

The steering column control module (SCCM) is the module on the steering column which, amongst other things, contains the ignition lock and the turn signal and wiper switches. It combines the following sub-systems (some of which are optional).

Immobilizer, steering wheel controls, transponder aerial, ignition lock, turn signal stalk, main/dipped beam stalk, cruise control stalk, Info Display buttons, windscreen wiper stalk, radio receiver for the key remote control, steering angle sensor, horn button, PEPS start button (passive entry passive start system) and ESCL (electric steering column lock). The SCCM has been developed to reduce the complexity of the wiring and reduce the weight of the steering column.
