What is B0135?

The diagnostic trouble code (DTC) B0135 indicates a malfunction related to the airbag system, specifically pointing to a fault in the airbag sensor circuit. This code is common in various vehicle makes, including Honda, Toyota, and Ford, particularly models manufactured between 2000 and 2015. When the airbag sensor circuit fails, it can lead to the airbag not deploying in the event of a collision, significantly increasing the risk of injury during an accident. The code can be triggered by various issues, such as a faulty airbag sensor, damaged wiring, or poor connections. In addition to impacting the airbag's functionality, this code often activates the airbag warning light on your dashboard, leading to a potentially alarming situation for drivers. Ignoring this issue can have serious consequences; therefore, it is crucial to address the underlying problems indicated by the B0135 code. If you encounter this code, it is essential to have a professional technician perform a thorough diagnostic using tools like the GeekOBD APP to pinpoint the exact cause and ensure your vehicle's safety features are fully operational.
