B2202 No Communication to VICS Module (No Fitting of VICS)

The OBD2 code B2202 indicates that there is no communication with the Vehicle Integrated Control System (VICS) module, which may not be installed in the vehicle

Definition

The OBD2 code B2202 indicates that there is no communication with the Vehicle Integrated Control System (VICS) module, which may not be installed in the vehicle

Common causes

  • Faulty VICS module
  • Disconnected or damaged wiring harness
  • Corroded connectors
  • Blown fuse
  • Faulty PCM (Powertrain Control Module)
  • Software issues or programming errors
  • Grounding issues
  • Intermittent electrical connections

Common misdiagnoses

  • Faulty wiring or connectors
  • Defective VICS module
  • Issues with the vehicle's main computer (ECU)
  • Problems with other communication modules
  • Incorrectly configured or programmed vehicle settings
  • Battery or power supply issues
  • Faulty sensors related to the VICS system

Troubleshooting steps

  1. 1. Check for Other Codes

    Use an OBD-II scanner to check for any additional trouble codes. This can provide more context and help identify related issues

  2. 2. Inspect the VICS Module

    Locate the VICS module and visually inspect it for any signs of damage, corrosion, or loose connections

  3. 3. Ensure that the module is securely mounted and that all connectors are properly seated

  4. 4. Check Wiring and Connectors

    Inspect the wiring harness leading to the VICS module for any signs of wear, fraying, or damage

  5. 5. Check the connectors for bent pins, corrosion, or dirt that could impede communication

  6. 6. Test Power and Ground

    Use a multimeter to check that the VICS module is receiving the correct voltage and ground. Refer to the vehicle’s service manual for the specific voltage requirements

  7. 7. If there is no power or ground, trace the wiring back to the source to identify any breaks or shorts

  8. 8. Perform a Communication Test

    Use a scan tool to attempt to communicate with the VICS module. If communication is not established, it may indicate a faulty module or wiring issue

  9. 9. If possible, try connecting a known good VICS module to see if communication is established

  10. 10. Check for Short Circuits

    Inspect the wiring for any short circuits that may be causing the VICS module to not communicate properly

  11. 11. Use a multimeter to check for continuity and resistance in the wiring

  12. 12. Inspect Related Modules

    Sometimes, issues with other modules can affect communication. Check for any faults in related control modules that may impact the VICS module

  13. 13. Update or Reprogram the Module

    If the VICS module is functioning but still not communicating, it may require a software update or reprogramming. Consult the manufacturer’s guidelines for the procedure

  14. 14. Clear Codes and Test Drive

    After performing repairs, clear the trouble codes and take the vehicle for a test drive to see if the code returns

  15. 15. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the VICS module or the specific vehicle model, as there may be known issues or fixes provided by the manufacturer.1

  16. 16. Seek Professional Help

    If the issue persists after following these steps, it may be necessary to consult a professional mechanic or dealership for further diagnosis and repair. By following these troubleshooting steps, you can systematically identify and resolve the issue related to the B2202 code
