What is B08AE?

DTC B08AE is a diagnostic trouble code that indicates a problem with the vehicle's occupant classification system, specifically relating to the passenger seat. This code primarily signifies that the system is unable to determine the proper classification of the occupant in the front passenger seat, which is crucial for deploying airbags in the event of an accident. When this code triggers, it usually means that either the seat weight sensor is malfunctioning, there’s a wiring issue, or the module responsible for interpreting the sensor's data is faulty. For car owners, this can lead to serious safety concerns as the airbag system may not deploy correctly in a crash, increasing the risk of injury. Additionally, you may notice that the airbag warning light remains illuminated, which serves as a visual reminder that there's an issue that needs to be addressed. Since DTC B08AE is common in vehicles like the 2015-2018 Honda Accord and Toyota Camry, it’s essential to seek prompt diagnostics and repairs to ensure the safety systems are functioning correctly and your vehicle remains roadworthy.

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

Symptoms

Common symptoms when B08AE is present:

  • The airbag warning light on the dashboard stays illuminated, indicating a fault in the airbag system.
  • You may experience erratic behavior of the passenger seat sensors, with the seatbelt warning chime sounding even when a passenger is present.
  • Fuel economy could drop by about 5-10% if the system is struggling with sensor data, as the vehicle may limit performance to ensure safety.
  • Unusual seat movement or shifts during driving, which may indicate a problem with the seat's electronic connections.
  • The airbag system may not activate during an accident, posing a serious risk to passenger safety.

Possible Causes

Most common causes of B08AE (ordered by frequency):

  1. The most common cause of DTC B08AE is a faulty passenger seat weight sensor, which has a likelihood of about 60%. This sensor can fail due to wear and tear or electrical issues.
  2. Another significant cause is damaged wiring or connectors in the occupant classification system. This can occur due to moisture ingress or physical damage from repeated seat adjustments.
  3. A third cause could be a malfunctioning airbag control module, which interprets data from the sensors. Ensuring this module is updated and free from faults is crucial.
  4. Less commonly, an unintentional obstruction in the seat area (like personal items) can cause misreading of the sensor data, leading to this code.
  5. A rare but possible cause is a software glitch within the vehicle's onboard computer system, which may require a software update.
