What is B0966?
The DTC code B0966 refers to a malfunction in the airbag system, specifically indicating an issue with the driver's side airbag or its related components. This code is particularly prevalent in vehicles like the 2015-2018 Honda Accord, but can also affect other models with similar airbag systems. When this code is triggered, it typically means that there's a fault in the airbag deployment circuit or a problem with the airbag control module. This can lead to the airbag light illuminating on your dashboard, indicating that your airbag may not deploy in the event of a collision, posing a serious safety risk. It's crucial for drivers to address this issue promptly to ensure that the airbag system functions correctly. Ignoring the B0966 code can lead to increased risk during accidents, as the airbag may fail to deploy when needed. Additionally, it can result in costly repairs if components are damaged further due to neglect. Regular diagnostic checks, especially if the airbag light is on, can help catch issues before they escalate.

Symptoms
Common symptoms when B0966 is present:
- The airbag warning light remains illuminated on the dashboard, signaling a fault in the airbag system.
- Drivers may notice that the airbag does not deploy during testing or in the event of a collision, which is a critical safety concern.
- There might be intermittent issues with the electrical components of the airbag system, leading to erratic behavior or failure to operate as expected.
- In some cases, drivers report a clicking sound near the steering wheel, indicating potential loose connections in the airbag wiring.
- The vehicle may exhibit other electrical issues, such as problems with the horn or other steering wheel controls due to shared wiring.
Possible Causes
Most common causes of B0966 (ordered by frequency):
- A common cause of the B0966 code is a faulty airbag control module, occurring in about 40% of cases. This module is responsible for managing the airbag deployment system.
- Loose or corroded wiring in the airbag system can trigger the B0966 code. This is found in approximately 30% of reported cases. Regular inspections can prevent this.
- A malfunctioning driver's side airbag sensor is another typical cause, accounting for 20% of issues. Ensuring the sensor is clean and properly connected can help mitigate the risk.
- In rare instances, software issues in the vehicle's computer system may lead to erroneous codes, although this is less common.
- Physical damage to the airbag itself, such as from a previous accident, can also result in the B0966 code, albeit infrequently.
