Non-functional steering wheel buttons on your 2023 Chevrolet Traverse affect convenience features like audio control, phone operation, and cruise control. These buttons communicate through the clock spring and vehicle network, so failures can stem from multiple sources.
Steering Wheel Control System
Steering wheel buttons connect through the clock spring (spiral cable) to the vehicle's electrical system. The switches send signals to control modules that execute the requested functions. Failures anywhere in this chain affect button operation.
Clock Spring Failures
The clock spring maintains electrical continuity while allowing steering wheel rotation. A broken or damaged clock spring interrupts all steering wheel electrical functions—buttons, horn, and airbag connections. Clock spring issues often affect multiple functions simultaneously.
Individual Switch Failures
Individual buttons can fail from wear, contamination, or internal damage. If only specific buttons don't work while others function normally, the switch module for that button group may be faulty.
Module Communication
Steering wheel switch signals travel to various control modules (radio, cruise control, etc.). Communication issues or module faults can prevent buttons from executing functions even when switches work correctly.
Software and Programming
Steering wheel button functions are software-defined. Updates or glitches can affect what buttons do or whether they work at all. Reset procedures or software updates may address some issues.
Code B100B and Control Circuits
Code B100B relates to steering wheel switch or control module communication. This code indicates the system has detected issues with button signal transmission.
