Module, Steering Column (SCM): Operation

WARNING: This page is about a different car, the 2020 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The components of the Steering Column Control Module (SCCM) each have one or more integral connector receptacles that connect them to each other and to the vehicle electrical system through dedicated take outs, and connectors of the instrument panel wire harness. For additional details, see the service information covering the individual SCCM component as follows:

Clockspring -. Refer to CLOCKSPRING, OPERATION .
Multifunction Switch -. Refer to SWITCH, MULTIFUNCTION, OPERATION .
Steering Angle Sensor -. Refer to SENSOR, STEERING WHEEL ANGLE, DESCRIPTION .

The hardwired circuits between components related to the SCCM may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to STANDARD PROCEDURE , REMOVAL , and INSTALLATION .

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the SCCM electronic components or the electronic controls and communication between modules and other devices that rely upon inputs from the SCCM components to provide some features. The most reliable, efficient and accurate means to diagnose the SCCM components or the electronic controls and communication related to SCCM component operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
