B1995Driver Sid Side mount Airbag Low resistance on Squib

The OBD2 code B1995 indicates a low resistance issue in the driver's side airbag squib circuit, which may suggest a problem with the airbag itself, the wiring, or the connectors related to the side mount airbag system

Definition

The OBD2 code B1995 indicates a low resistance issue in the driver's side airbag squib circuit, which may suggest a problem with the airbag itself, the wiring, or the connectors related to the side mount airbag system

Common causes

  • Faulty side airbag squib
  • Damaged wiring or connectors
  • Poor ground connection
  • Corroded terminals
  • Airbag module malfunction
  • Faulty airbag control module
  • Incorrect installation of side airbags
  • Short circuit in the airbag circuit

Common misdiagnoses

  • Faulty airbag module
  • Damaged wiring or connectors
  • Faulty side impact sensor
  • Defective airbag squib
  • Poor ground connection
  • Faulty seat belt pretensioner
  • Incorrectly installed or replaced airbag
  • Software or calibration issues in the airbag system

Troubleshooting steps

  1. 1.Safety First

    Disconnect the Battery: Before working on any airbag system, disconnect the negative terminal of the battery to prevent accidental deployment of the airbag

  2. 2.Wait

    Allow at least 10-15 minutes after disconnecting the battery to ensure that any residual power in the system is dissipated

  3. 3.Visual Inspection

    Wiring and Connectors: Inspect the wiring harness and connectors associated with the side airbag. Look for signs of damage, corrosion, or loose connections

  4. 4.Airbag Module

    Check the airbag module for any physical damage or signs of wear

  5. 5.Check Resistance

    Squib Resistance: Use a multimeter to measure the resistance of the airbag squib. The resistance should typically be within the manufacturer's specified range (usually around 2-3 ohms). If the resistance is too low, it may indicate a short circuit

  6. 6.Wiring Continuity

    Check for continuity in the wiring between the airbag module and the squib. Look for any breaks or shorts in the wiring

  7. 7.Connector Inspection

    Connector Pins: Inspect the pins in the connectors for corrosion, bending, or damage. Clean or repair as necessary

  8. 8.Secure Connections

    Ensure that all connectors are securely fastened and properly seated

  9. 9.Scan Tool Diagnosis

    Clear Codes: Use an OBD-II scanner to clear the B1995 code and any other related codes

  10. 10.Recheck Codes

    After clearing, take the vehicle for a test drive to see if the code returns. If it does, further investigation is needed

  11. 11.Check for Other Codes

    Related Codes: Look for any other related trouble codes that may provide additional context or indicate a broader issue with the airbag system

  12. 12.Component Testing

    Replace the Squib: If the squib is found to be faulty (low resistance), it may need to be replaced. Ensure that you use OEM or high-quality replacement parts

  13. 13.Airbag Module

    If all other components check out, the airbag control module itself may be faulty and require replacement

  14. 14.Reassemble and Test

    Reconnect Battery: Once all checks and repairs are made, reconnect the battery

  15. 15.Final Test

    Use the OBD-II scanner to check for any codes again and ensure that the airbag system is functioning properly

  16. 16.Professional Help

    If the issue persists after following these steps, it may be necessary to consult a professional technician or a dealership with specialized equipment for further diagnosis.Important Notes: - Always follow manufacturer-specific service manuals and guidelines when working on airbag systems. - If you are not comfortable or experienced with airbag systems, it is highly recommended to seek professional assistance due to the safety risks involved
