What is B080E?

The Diagnostic Trouble Code (DTC) B080E indicates a problem related to the airbag control module, specifically signaling a fault with the airbag system. This code is prevalent in various vehicles, particularly in models from manufacturers like Ford, Chevrolet, and Honda manufactured between 2015 and 2019. When the B080E code is triggered, it means that the airbag control module has detected a malfunction in one of its systems, often due to issues such as a faulty sensor, wiring problems, or a malfunctioning module itself. It can lead to the airbag warning light being illuminated on the dashboard, indicating that the airbag system may not deploy properly in the event of an accident. The implications of ignoring this code are significant, as it directly affects passenger safety. It is essential to address B080E promptly to ensure that your vehicle's airbag system is functional, thus protecting both drivers and passengers in the unfortunate case of a collision.

Symptoms

Common symptoms when B080E is present:

  • The airbag warning light stays illuminated on the dashboard, indicating a malfunction in the airbag system.
  • Drivers may experience intermittent airbag deployment warnings or notices, which can cause confusion and concern.
  • The vehicle may exhibit a loss of airbag functionality, which is a critical safety concern during an accident.
  • In some cases, the vehicle's onboard diagnostic system may show additional codes related to airbag sensors or modules.
  • There might also be an audible warning chime or alert when the ignition is turned on, signaling a system check failure.

Possible Causes

Most common causes of B080E (ordered by frequency):

  1. A faulty airbag sensor is the most common cause, accounting for approximately 40% of B080E occurrences. This can happen due to wear and tear or physical damage.
  2. Wiring issues, such as frayed wires or poor connections, can also trigger this code. It's crucial to inspect the wiring harnesses that connect to the airbag system.
  3. A malfunctioning airbag control module itself can contribute to this code, making it necessary to test and possibly replace the module.
  4. Less frequently, issues with the vehicle's battery or electrical system can lead to B080E, as power fluctuations may affect airbag performance.
  5. In rare cases, software glitches within the airbag control module can cause false readings, necessitating a software update or reset.
