What is B1035?

DTC B1035 is a diagnostic trouble code that indicates a malfunction in the airbag system, particularly related to the airbag sensor circuit. This code is commonly found in vehicles from manufacturers like Honda and Toyota, especially models such as the 2015-2018 Honda Accord and the 2014-2019 Toyota Camry. When this code is triggered, it generally means that the airbag control module has detected an issue with the resistance or continuity of the airbag sensor circuit. This could prevent the airbag from deploying in the event of a collision, significantly compromising passenger safety. It’s crucial to address this code promptly, as ignoring it can lead to serious safety risks. In addition, the airbag warning light will typically illuminate on the dashboard, alerting the driver to a potential problem. Regular inspections and maintenance can help prevent such occurrences. If B1035 is present, a qualified technician should conduct a thorough diagnostic to pinpoint the exact source of the problem, which may involve checking the wiring, connectors, and the airbag control module itself. Overall, understanding DTC B1035 is essential for ensuring that your vehicle's safety systems are functioning correctly.

Symptoms

Common symptoms when B1035 is present:

  • The airbag warning light remains illuminated on the dashboard, signaling a malfunction within the airbag system.
  • Inconsistent operation of seatbelt pretensioners, which may fail to engage properly during a collision.
  • In some cases, the vehicle may experience intermittent electronic malfunctions, such as the dashboard lights flickering.
  • The car may display a message indicating a fault in the airbag system, providing users with a heads-up to the issue.
  • In severe cases, the airbag may deploy unexpectedly, which can result in injury or damage.

Possible Causes

Most common causes of B1035 (ordered by frequency):

  1. The most common cause of B1035 is a faulty airbag sensor, accounting for about 45% of cases. This can occur due to wear and tear over time.
  2. A second common cause is damaged wiring or connectors in the airbag system, with a likelihood of around 30%. This may happen due to corrosion or physical damage.
  3. Improper installation of aftermarket parts, such as steering wheels or seats, can lead to airbag sensor issues, constituting about 15% of cases. Always ensure proper installation.
  4. Less commonly, a malfunctioning airbag control module may trigger the B1035 code, which can be serious as it directly impacts the airbag deployment function.
  5. A rare cause includes software glitches in the vehicle's onboard computer system, which could lead to false codes being triggered.
