Centralizes Control of Steering-Column Functions The SCM operates: Turn signals Wipers & washers Headlights (high/low beam) Horn Steering wheel buttons (cruise, audio, phone) All these functions run through the module. 2. Communicates With Vehicle Electronics The SCM sends and receives signals through the vehicle's network (CAN bus or LIN bus), allowing the car’s computer systems to respond to driver inputs. 3. Integrates Safety Systems It works with the: Clock spring (airbag wiring) Steering angle sensor (for stability control, ABS, traction control) These systems rely on accurate information from the module. 4. Improves Driver Convenience Instead of separate switches, the SCM allows modern controls to be: Integrated Multi-functional Smart (auto wipers, auto lights, etc.) 5. Supports Advanced Features Some SCMs also control: Electronic steering locks Ignition switches (push-to-start systems) Adaptive lighting Lane-keeping steering input sensors Signs of a Bad Steering Column Module 1NJ75DX9AD: 1.

Steering Wheel Button Failures Radio controls not responding Cruise control won’t turn on Phone or menu buttons stop working This can be caused by SCM failure or clock spring issues. 6. Airbag Warning Light The SCM works with the clock spring; if it can’t read correct signals: Airbag light stays on Steering wheel airbag may be disabled (safety issue) 7. Steering Angle Sensor Errors If the SCM houses or communicates with the steering angle sensor: ABS lights Traction control lights Stability control lights “Service steering” or “ESC” warning 8. Strange Electrical Behavior Random clicking noises in the steering column Components activating without touching controls Intermittent failures of multiple switches This often indicates a failing internal circuit. 9.
