Definition

The OBD2 code C1467 indicates a short circuit in the high side rear damper circuit, meaning there is an electrical fault causing the circuit to connect directly to the battery voltage, potentially leading to improper operation of the damper system

Common causes

  • Damper actuator failure
  • Shorted wiring or connectors
  • Corroded or damaged electrical connections
  • Faulty control module
  • Grounding issues
  • Improper installation or modifications

Common misdiagnoses

  • Damper actuator failure
  • Wiring harness issues
  • Shorted wiring
  • Faulty control module
  • Grounding problems
  • Incorrectly calibrated sensors
  • Other HVAC component failures
  • Battery or charging system issues

Troubleshooting steps

  1. 1. Verify the Code

  2. 2. Use an OBD-II scanner to confirm that the C1467 code is present. Check for any other related codes that may provide additional context

  3. 3. Inspect Wiring and Connectors

  4. 4. Visually inspect the wiring and connectors associated with the rear damper circuit. Look for signs of damage, fraying, corrosion, or loose connections

  5. 5. Pay special attention to areas where the wiring may be exposed to heat or moving parts

  6. 6. Check for Short Circuits

  7. 7. Use a multimeter to check for continuity in the circuit. Disconnect the battery and the affected component, then test for continuity between the high side circuit and the battery positive terminal

  8. 8. If continuity is present where it shouldn't be, there may be a short circuit in the wiring

  9. 9. Test the Damper Actuator

  10. 10. If applicable, test the rear damper actuator for proper operation. This may involve applying power directly to the actuator to see if it functions correctly

  11. 11. Check the resistance of the actuator to ensure it is within specifications

  12. 12. Inspect the Control Module

  13. 13. If the wiring and actuator are in good condition, the issue may lie with the control module. Check for any signs of damage or corrosion on the module connectors

  14. 14. If possible, perform a reset of the control module and see if the code returns

  15. 15. Check for Ground Issues

  16. 16. Ensure that the ground connections for the damper circuit are secure and free of corrosion. A poor ground can cause erratic behavior and trigger fault codes

  17. 17. Look for Related Issues

  18. 18. Investigate if there are any other systems or components that may be affecting the damper circuit. Sometimes, issues in one area can cause problems in another

  19. 19. Consult Technical Service Bulletins (TSBs)

  20. 20. Check for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued guidance on common issues related to the damper circuit

  21. 21. Clear the Code and Test Drive

  22. 22. After performing repairs or adjustments, clear the code using the OBD-II scanner and take the vehicle for a test drive to see if the code returns

  23. 23. Seek Professional Help

  24. 24. If the issue persists after following these steps, it may be necessary to consult a professional mechanic or technician who has experience with the specific vehicle and its systems. By following these steps, you should be able to identify and resolve the issue related to the C1467 code. Always refer to the vehicle's service manual for specific procedures and specifications
