WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
The Steering Control Module (SCM) 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.
- Steering Wheel Switches
- Horn
- Speed Control Switch
- Multi-function Switch
- Tilt/Telescoping Switch (if equipped)
- Steering Angle Sensor (if equipped with Electronic Stability Program (ESP))
- Steering Control Module (SCM)
The SCM changes the LIN communication to CAN communication and also stores Diagnostic Trouble Codes (DTC's) for the switches within the SCCM.
For removal and installation, disassembly and assembly of the SCCM, refer to the following:
NOTE:
For Steering Column Module (SCM) removal and installation, refer to the disassembly and assembly procedures for the Steering Column Control Module (SCCM).
- Removal of SCCM (Refer to STEERING/COLUMN/STEERING COLUMN CONTROL MODULE - REMOVAL) .
- Disassembly of SCCM (Refer to STEERING/COLUMN/STEERING COLUMN CONTROL MODULE - DISASSEMBLY) .
- Assembly of SCCM (Refer to STEERING/COLUMN/STEERING COLUMN CONTROL MODULE - ASSEMBLY) .
- Installation of the SCCM (Refer to STEERING/COLUMN/STEERING COLUMN CONTROL MODULE - INSTALLATION) .
The SCM is not serviceable and if found faulty, it must be replaced as a unit.
