To prevent B102D, regularly inspect the airbag system during maintenance, avoid modifications to the seating area, and ensure that any repairs are performed by qualified professionals.

What is B102D?

DTC B102D is a diagnostic trouble code that indicates an issue within the vehicle's airbag system, specifically related to the passenger airbag. This code suggests that the airbag control module has detected an issue with the airbag deployment circuit or the passenger seat occupancy sensor. When this code is present, it usually means that the airbag light is illuminated on the dashboard, indicating that the airbag system is not functioning properly. This can have serious implications for the safety of you and your passengers in the event of a collision. It's essential to address this issue promptly as it could prevent the airbag from deploying during an accident, significantly increasing the risk of injury. The problem may stem from various sources, including faulty wiring, a malfunctioning sensor, or an issue with the airbag control module itself. If you own a vehicle like the 2017 Honda Accord, it’s crucial to have this code diagnosed and repaired by a professional as soon as possible to ensure your vehicle’s safety systems are fully operational.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B102D is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a malfunction in the airbag system.
  • You may notice that the passenger airbag status indicator shows 'OFF' even when there is a passenger in the seat, suggesting a sensor issue.
  • In some cases, the vehicle may exhibit erratic behavior in the airbag system, such as false alarms or intermittent warnings.
  • Unexpected alerts or warnings related to the airbag system may appear during vehicle operation.
  • Increased difficulty when attempting to reset the airbag light using diagnostic tools, indicating a persistent issue.

Possible Causes

Most common causes of B102D (ordered by frequency):

  1. The most common cause of B102D is a faulty passenger seat occupancy sensor, which has a likelihood of approximately 60%. This sensor detects whether or not a passenger is seated and communicates this to the airbag control module.
  2. Another common cause is damaged wiring or connectors in the airbag system, which could result from wear and tear or exposure to moisture. This issue has a likelihood of about 25%.
  3. A malfunctioning airbag control module itself can also trigger this code, with a prevention tip being to ensure regular checks during vehicle maintenance to catch any potential issues early.
  4. Less common but serious causes may include a software issue within the vehicle's control systems that require a firmware update.
  5. A rare cause might be an unqualified installation of aftermarket seats or equipment that interferes with the airbag system.
