MODULE, Steering Column Control: Description: Description

WARNING: To service any component of the SCCM, the entire assembly must be removed from the column. This must be done due to the clockspring passing through the assembly and into the self docking connector. Failure to remove the assembly could damage the pins of the clockspring and prevent the airbag system from operating properly.

NOTE: The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain components may also reference ESP, ESC, or use the traction control symbol.

Tilt and telescope steering columns are standard on all models. On 300 Hemi C and international 300C models the tilt and telescope functions are powered and are also included in the standard Memory System settings. Combined with available power seats and optional power adjustable pedals, the tilt and telescope steering column gives the driver every known adjustment to obtain a comfortable driving position. Both columns provide 2.36 inches (60 mm) of telescoping adjustment and 5.2 degrees of tilt. The adjustments are continuously variable for maximum adaptability.

A lever on the left side of the column controls powered adjustment. Fore and aft motion of the lever operates the telescoping mechanism. Up and down motion operates the tilt mechanism. Two electric motors turning threaded actuators move the column. The mechanisms lock in place when movement stops.

The Steering Column Control Module (SCCM) is mounted on the steering column and is removed as a complete unit. The components that are contained within this unit are:

Clockspring - is attached to the top of the SCCM with three screws. The clockspring connector passes through the body of the SCCM and its terminals slide into the male side of the self docking connector within the Steering Column Module (SCM). Refer to Restraints - Description .
Multi-Function Switch - is the middle left lever, and is plugged into, and mounting pins pass through, the SCM secured to the SCCM housing by three screws. Refer to Electrical/Lamps/Lighting - Exterior/SWITCH, Multifunction - Description .
Steering Angle Sensor (if equipped with Electronic Stability Control (ESC) - is mounted on the right side of the SCCM, below the clockspring and is responsible for informing the ESC of steering angle.
Steering Control Module (SCM) - is the module located in the bottom of the SCCM, retained by three screws, and is the mating point for all the switches and clockspring located in the SCCM.
Tilt/Telescopic Lever/Switch (if equipped) - is the bottom left lever and is used for steering wheel tilt and telescoping. It is plugged into the SCM and if not equipped, will be replaced by a support bar. It is held in place by one the three clockspring screws and one of its own retaining screws.
Shroud - is the outer housing or shell of the SCCM.

The SCCM communicates via the Local Interconnect Network (LIN) serial data bus. This is an ultra-low voltage serial data bus that allows the following components to communicate with the Controller Area Network (CAN) B and C data buses.
