Code B0084 Description
The B0084 diagnostic trouble code (DTC) specifically relates to the right front impact sensor in the vehicle's airbag system. This sensor is responsible for detecting a collision or impact on the right front side of the vehicle and sending a signal to the airbag control module to deploy the airbags if necessary. When this sensor detects a fault or malfunction, it can prevent the airbags from deploying in the event of a collision, compromising the safety of the vehicle occupants.
Common Causes of B0084
- Faulty right front impact sensor.
- Damaged wiring or connectors leading to the sensor.
- Corrosion or debris interfering with the sensor's operation.
- Impact sensor calibration or programming issues.
- Water damage or exposure affecting the sensor's functionality.
Symptoms of B0084
- Airbag warning light illuminated on the dashboard.
- Airbag system fault message displayed on the instrument cluster.
- Airbags may not deploy in a collision.
- The vehicle may fail an airbag system diagnostic test.
How to Fix B0084
- Begin by diagnosing the specific cause of the B0084 code using a scan tool to retrieve the fault codes and pinpoint the issue.
- Inspect the right front impact sensor and its wiring for any visible damage, corrosion, or loose connections. Repair or replace any damaged components as needed.
- Test the sensor's functionality by simulating an impact or collision scenario to ensure it detects properly and sends the signal to the airbag control module.
- Clear the fault codes from the airbag system and perform a test drive to verify that the issue has been resolved and the airbag warning light is no longer illuminated.
- If the problem persists, further diagnosis may be necessary to identify any underlying issues with the airbag system components or connections.
Cost to Fix B0084
The cost of repairing a B0084 code related to the right front impact sensor can vary depending on the specific cause of the issue and the labor rates in your area. Typically, the cost of replacing the impact sensor itself can range from $100 to $300, while addressing wiring or connector issues may add to the total repair cost. On average, the total repair cost for this issue could range from $200 to $500 including parts and labor. It is recommended to consult with a qualified mechanic or auto repair shop for an accurate estimate based on your vehicle's make and model.

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.
