The Steering Column Control Module (SCCM) is located near the top of the steering column below the steering wheel. The SCCM includes the Steering Angle Sensor (SAS), the clockspring, the left (lighting) multifunction switch, the right (wiper) multifunction switch, and a steering column power tilt and telescope switch (if so equipped).

The SCCM is secured to the steering column by an integral band clamp on the bottom of the instrument panel side of the SCCM. The SCCM has a centering attachment screw located on the top of the instrument panel side of the SCCM to be certain the SCCM is centered properly on the steering column.

There are also unique lugs cast into the outer circumference of the steering wheel hub that must be engaged into slots within the inner circumference of the clockspring rotor hub to unlock and drive both the clockspring and the SAS. The steering wheel must be tightened to specification to ensure proper clockspring and SAS function.

The SCCM includes two integral connector receptacles that face toward the steering wheel (front side) and are connected to the steering wheel electrical components through two take outs and connectors of the steering wheel wire harness. The receptacle at the 9 o'clock position contains the circuits for the Local Interface Network (LIN) data bus to the Body Control Module (BCM), the LIN data bus to the SCCM (internal to the SCCM), the horn signal, B(+) with Positive Thermal Coefficient (PTC), ground and shifter paddle signal (if so equipped). The receptacle at the 3 o'clock position contains the circuits for the heated steering wheel (if so equipped). Both radio control switches are hard wired to the Electronic Vehicle Information Center (EVIC) switch on the left steering wheel spoke, which then uses the LIN data bus to communicate with the BCM. The surface of the rotor hub facing the steering wheel (front side) also has three short pigtail wires with connectors. The pigtail connectors contain the circuits for the Driver Air Bag (DAB).

The SCCM also includes two integral connector receptacles that face toward the instrument panel (back side) and are connected to the vehicle electrical system through two take outs and connectors of the instrument panel wire harness. The 14-way receptacle at the 6 o'clock position contains the circuits for heated steering wheel (if so equipped) from the Comfort Seat Wheel Module (CSWM) and the Driver Air Bag (DAB) from the Occupant Restraint Controller (ORC) module. The 12-way receptacle at the 9 o'clock position contains the circuits for the LIN data bus to the BCM, the horn signal to the BCM, fused B(+), ground and the Controller Area Network - Chassis (CAN C) data bus.

The SCCM cannot be adjusted or repaired. If ineffective or damaged, the entire SCCM must be replaced as a unit.
