What is B096D?
The diagnostic trouble code B096D refers to an issue with the Comfort Control Module (CCM), particularly in vehicles manufactured by Chevrolet and GMC between 2015 and 2020. This code indicates that the CCM has detected a fault in its communication or operational parameters. The Comfort Control Module is responsible for managing various comfort-related features in your vehicle, such as climate control, power windows, and door locks. When this code activates, it often triggers warning lights on the dashboard and can lead to malfunctions in the systems it controls. For example, you may experience issues like windows not responding, climate control settings failing, or even the inability to lock or unlock doors. Ignoring this code can lead to further complications, including complete failure of these systems, which can be both inconvenient and costly to repair. If you see B096D, it’s vital to address it promptly to ensure your vehicle's comfort features function correctly and maintain overall vehicle safety and reliability.
