What is B0980?

The diagnostic trouble code (DTC) B0980 indicates a fault in the vehicle's occupant detection system, often relating to the airbag system. This code is commonly associated with vehicles like the 2013-2017 Honda Accord and 2015-2019 Toyota Camry. When this code is triggered, it typically means that the system has detected an issue with the sensors that monitor the presence and weight of the passenger in the front seat. This could lead to airbag deployment issues, potentially compromising safety in the event of an accident. The occupant detection system is crucial for ensuring that airbags deploy correctly based on the weight and position of the passenger. If the system fails, it may prevent the airbag from deploying in an accident, significantly increasing the risk of injury. It’s important to address this code promptly as it indicates a serious safety concern that could affect the vehicle's overall functionality and safety features. Ignoring this code may lead to further complications, including additional damage to the vehicle’s safety systems and increased repair costs down the line.

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

Symptoms

Common symptoms when B0980 is present:

  • The airbag warning light illuminates on the dashboard, indicating a fault within the safety system.
  • Inconsistent airbag deployment during simulations or tests, which can be confirmed by diagnostic tools.
  • The passenger seat may not register weight correctly, leading to airbag deactivation when a passenger is present.
  • Unusual noises from the seat area may indicate faulty sensors or wiring issues.
  • A noticeable delay or failure of the airbag system to activate during safety checks.

Possible Causes

Most common causes of B0980 (ordered by frequency):

  1. A faulty occupant sensor, which is the most common cause (around 60%), may require replacement.
  2. Damaged wiring or connectors that affect the sensor’s signal transmission, often due to wear and tear.
  3. Poor calibration of the occupant detection system, which can happen after an accident or seat replacement.
  4. Less common, but serious, is a malfunctioning airbag control module that may require reprogramming or replacement.
  5. In rare cases, software glitches in the vehicle's computer can be the root cause, necessitating a software update.
