Grand Caravan V6-4.0L (2008)
Combination Switch: Description and Operation
DESCRIPTION
The clockspring mounting bracket provides mounting support for the multi-function switch and the adjustable pedal switch, (If equipped) both of which
can be removed from the clockspring mounting bracket and are available for individual service replacement. When combined, these components are
sometimes referred to as the Steering Column Control Module (SCCM). The multi-function switch includes the switch control stalk, a dedicated
connector receptacle as well as an internal electronic circuit board and a microprocessor that is also known as the Steering Control Module (SCM). The
SCM within the multi-function switch is a Local Interface Network (LIN) slave and communicates over a dedicated LIN bus circuit with the
ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), which is the LIN master. The SCM is not flash update
capable. The adjustable pedal switch has an integral connector receptacle and is a hard wired circuit component. The mult-function switch controls the
turn signals, the head lamp beam select, front wipers and wash features and the rear wipe and wash functions.
