Definition

The OBD2 code B2200 indicates that there is no communication with the TV (Television) module, typically due to the absence of the module in the vehicle

Common causes

  • Faulty TV module
  • Damaged wiring or connectors
  • Poor ground connection
  • Blown fuse
  • Corroded terminals
  • Software or programming issues
  • Faulty communication network (CAN bus issues)
  • Intermittent electrical connections

Common misdiagnoses

  • Faulty wiring or connectors
  • Defective TV module
  • Malfunctioning body control module (BCM)
  • Issues with the CAN bus system
  • Power supply problems to the TV module
  • Software or firmware issues in the vehicle's control modules
  • Incorrectly programmed or incompatible TV module
  • Faulty ground connections

Troubleshooting steps

  1. 1. Check for Other Codes

    Use an OBD-II scanner to check for any additional trouble codes. Sometimes, multiple codes can provide more context for the issue

  2. 2. Inspect the Wiring and Connectors

    Visual Inspection: Check the wiring harness and connectors related to the TV (Television) module for any signs of damage, corrosion, or loose connections

  3. 3. Connector Pins

    Ensure that the pins in the connectors are not bent or corroded

  4. 4. Verify Power and Ground

    Power Supply: Use a multimeter to check if the TV module is receiving the correct voltage

  5. 5. Ground Connection

    Ensure that the ground connection for the TV module is intact and has a good connection

  6. 6. Check for Communication

    CAN Bus Communication: If the vehicle uses a CAN bus system, check if the TV module is properly connected to the bus. You can use a scan tool to see if other modules are communicating correctly

  7. 7. Module Functionality

    If possible, test the TV module in another vehicle to confirm it is functioning properly

  8. 8. Inspect the TV Module

    If the module is accessible, check for any physical damage or signs of water intrusion

  9. 9. If the module is not present (as indicated by "No Fitting of TV"), you may need to verify if the vehicle is supposed to have this module and if it has been removed or replaced

  10. 10. Check for Software Issues

    Reprogramming: In some cases, the module may need to be reprogrammed or updated. Check with the manufacturer for any software updates

  11. 11. Resetting the Module

    Disconnect the battery for a few minutes to reset the vehicle’s computer and see if the code clears

  12. 12. Consult Technical Service Bulletins (TSBs)

    Look for any TSBs related to the B2200 code or the TV module for your specific vehicle make and model. Manufacturers may have known issues and recommended fixes

  13. 13. Professional Diagnosis

    If the issue persists after performing the above steps, consider taking the vehicle to a professional mechanic or dealership for a more in-depth diagnosis

  14. 14. Document Findings

    Keep a record of all findings, tests performed, and any changes made. This documentation can be helpful for future reference or if you need to consult a professional. By following these steps, you should be able to identify the cause of the B2200 code and take appropriate action to resolve the issue
