Code B0086 2018 Chevrolet Silverado Description
The B0086 code on a 2018 Chevrolet Silverado refers to an issue with the Right Front Side Impact Sensor. This sensor is a crucial component of the vehicle's safety system, as it is responsible for detecting impacts on the right front side of the vehicle and triggering the deployment of the airbags in the event of a collision. When this sensor malfunctions or fails to communicate properly with the vehicle's onboard computer, it can compromise the overall safety of the vehicle.
Common Causes of B0086 2018 Chevrolet Silverado
- Impact damage: The Right Front Side Impact Sensor is located on the front right side of the vehicle, where it is vulnerable to damage in a collision. If the sensor has been physically damaged, it may not function correctly.
- Electrical issues: Wiring harnesses and connectors that connect the sensor to the vehicle's electrical system can also cause the sensor to malfunction. Corrosion, loose connections, or short circuits can disrupt the sensor's communication with the onboard computer.
- Software issues: Sometimes, the problem may lie in the software that controls the sensor. Updates or reprogramming may be necessary to resolve the issue.
- Sensor failure: Like any electronic component, the sensor itself may fail over time due to wear and tear or manufacturing defects.
- Environmental factors: Extreme temperatures, moisture, or vibration can also affect the sensor's performance and lead to a malfunction.
Symptoms of B0086 2018 Chevrolet Silverado
- Airbag warning light on the dashboard: One of the most common symptoms of a faulty Right Front Side Impact Sensor is the illumination of the airbag warning light on the dashboard. This indicates that there is a problem with the sensor or the airbag system.
- Non-deployment of airbags: If the sensor is not functioning properly, it may fail to trigger the deployment of the airbags in a collision, leaving the occupants unprotected.
- False airbag deployment: On the other hand, a malfunctioning sensor may also cause the airbags to deploy unexpectedly, which can be dangerous for the occupants, especially if there is no actual collision.
- Erratic behavior of other safety systems: A faulty sensor may also cause other safety systems, such as seatbelt pretensioners, to behave erratically or not deploy when needed.
How to Fix B0086 2018 Chevrolet Silverado
- Diagnose the issue: The first step in repairing the Right Front Side Impact Sensor is to diagnose the problem accurately. This may involve using a scan tool to retrieve the fault codes and testing the sensor's functionality.
- Inspect for physical damage: Check the sensor and its surrounding components for any signs of physical damage. Replace any damaged parts as necessary.
- Check wiring and connections: Inspect the wiring harnesses and connectors for corrosion, loose connections, or damage. Repair or replace any faulty wiring.
- Update software: If the issue is related to software, updating or reprogramming the sensor's software may resolve the problem.
- Replace the sensor: If the sensor itself is faulty and cannot be repaired, it will need to be replaced with a new one.
Cost to Fix B0086 2018 Chevrolet Silverado

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.
