  12. 12. Check for Software Updates

  13. 13. Some vehicles may require software updates for the TV module or related systems. Check with the manufacturer or a dealership to see if any updates are available

  14. 14. Consult Technical Service Bulletins (TSBs)

  15. 15. Look for any TSBs related to the B2197 code or the TV module for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  16. 16. Professional Diagnosis

  17. 17. If the issue persists after performing the above steps, it may be necessary to take the vehicle to a qualified technician or dealership for further diagnosis. They may have specialized tools and knowledge to pinpoint the issue

  18. 18. Clear the Code

  19. 19. After performing repairs or inspections, clear the trouble code using an OBD-II scanner and take the vehicle for a test drive to see if the code returns. By following these steps, you should be able to identify and potentially resolve the issue associated with the B2197 code. If you're not comfortable performing these steps yourself, it's always best to consult with a professional mechanic
