Code B0084:39 Description
The B0084:39 code indicates a right front impact sensor internal electronic failure in the vehicle's safety system. Impact sensors are crucial components that detect collisions or accidents and trigger the deployment of airbags and other safety measures to protect the occupants. In this case, the right front impact sensor has experienced an internal electronic failure, which can compromise the system's ability to accurately detect impacts and deploy safety features when needed.
Common Causes of B0084:39
- Electrical issues such as wiring damage or corrosion.
- Impact sensor internal component failure.
- Vehicle collision or accident causing physical damage to the sensor.
- Software malfunction or calibration error.
- General wear and tear over time.
Symptoms of B0084:39
- Airbag warning light illuminated on the dashboard.
- Inaccurate or erratic deployment of airbags in a collision.
- Failure of seat belt pretensioners to activate.
- False alarms or unexpected airbag deployments.
How to Fix B0084:39
- Diagnose the specific cause of the B0084:39 code using a diagnostic scan tool.
- Inspect the right front impact sensor for physical damage or loose connections.
- Test the sensor's electrical connections and wiring for continuity and proper voltage.
- Replace the right front impact sensor if internal electronic failure is confirmed.
- Clear the diagnostic trouble codes and perform a test drive to ensure the issue is resolved.
Cost to Fix B0084:39
The cost of repairing a right front impact sensor internal electronic failure can vary depending on the make and model of the vehicle, the location of the repair shop, and the extent of the damage. On average, the parts for a new impact sensor can range from $100 to $300, while the labor costs can be between $150 and $300. Therefore, the total repair cost can be estimated to be between $250 and $600. It is advisable to consult with a qualified mechanic or repair shop for a more accurate cost estimate based on the specific circumstances of the vehicle.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
