What is B0245?

DTC B0245 is a diagnostic trouble code that indicates a malfunction related to the airbag system, specifically concerning the airbag sensor. This code is most frequently seen in vehicles such as the 2010-2015 Toyota Camry and Honda Accord, where it signifies that the airbag control module has detected an issue with the passenger airbag sensor's performance. The airbag sensor is crucial for the vehicle's safety systems, as it determines whether the airbag should deploy in the event of a collision. When the B0245 code is triggered, it typically means that the sensor circuit is either open or shorted, which can prevent the airbag from deploying correctly, posing a serious risk during an accident. In real-world terms, this fault could result in the airbag light illuminating on your dashboard, indicating that the airbag system is not functioning properly. It's essential to address this issue promptly, as it could compromise passenger safety. Ignoring this code could lead to costly repairs down the line, especially if an accident occurs and the airbag fails to deploy. Always consult a qualified technician when dealing with airbag system issues to ensure your safety and the integrity of the vehicle's safety features.

Symptoms

Common symptoms when B0245 is present:

  • The airbag warning light on your dashboard stays illuminated constantly, indicating a fault in the airbag system.
  • You may notice that the vehicle's airbag system is non-responsive in testing, meaning it won't deploy during a crash.
  • In some cases, the vehicle's stability control may also be disabled, resulting in decreased handling performance.
  • You could experience intermittent electrical issues, such as flickering dashboard lights when the airbag system is active.
  • The vehicle may trigger false alarms or warning messages related to the airbag system, causing confusion and concern.

Possible Causes

Most common causes of B0245 (ordered by frequency):

  1. A common cause of the B0245 code is a faulty airbag sensor, which accounts for approximately 60% of cases. This could be due to wear and tear or manufacturing defects.
  2. Another potential cause is damaged wiring or connectors within the airbag system, often resulting from friction or moisture exposure, contributing to around 25% of occurrences.
  3. Corroded or loose connections in the airbag control module can also trigger this code, which can be prevented through regular inspections and maintenance of the electrical system.
  4. Less commonly, a malfunctioning airbag control module itself can cause this code, which is a serious issue that may require replacement.
  5. In rare cases, software glitches in the vehicle's onboard computer can result in false DTC readings, necessitating a software update or reprogramming.
