What is B1922?

DTC B1922 indicates a malfunction within the airbag system, specifically related to the passenger side airbag. When this code appears, it typically means there is a fault in the airbag restraint system, which can compromise the safety features designed to protect occupants during a crash. This code is prevalent in vehicles like the 2010-2015 Honda Accord and the 2012-2016 Toyota Camry. When the B1922 code is triggered, the airbag warning light on the dashboard will illuminate, signaling that the system is not functioning correctly. It’s crucial to address this issue promptly, as a malfunctioning airbag system may not deploy during an accident, putting passengers at significant risk. Factors contributing to this code can include faulty sensors, wiring issues, or problems with the airbag module itself. Therefore, if you see a B1922 code, it's best to consult a professional technician to diagnose and repair the issue to ensure your vehicle's safety features are fully operational.

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

Symptoms

Common symptoms when B1922 is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a potential issue with the airbag system.
  • The passenger airbag may not deploy in the event of an accident, which can greatly increase the risk of injury.
  • You might experience inconsistent airbag performance, where the system may deactivate unexpectedly.
  • There may be a noticeable delay in airbag deployment during tests conducted by technicians.
  • Diagnostic tools may show additional trouble codes alongside B1922, indicating related issues.

Possible Causes

Most common causes of B1922 (ordered by frequency):

  1. The most common cause of B1922 is a faulty passenger airbag sensor, which has a likelihood of about 60%. This sensor can fail due to wear and tear or electrical issues.
  2. Another substantial cause is damaged wiring or connectors in the airbag system, often arising from physical damage or corrosion, accounting for approximately 25% of cases.
  3. A malfunctioning airbag control module can also trigger the B1922 code, though this is less common. Regular inspections can help prevent this issue.
  4. In rare cases, a severe impact or crash history could lead to a permanent airbag system failure, which is critical to address.
  5. Finally, a blown fuse related to the airbag system can cause the code to appear, although this is uncommon.
