What is B080B?

The diagnostic trouble code (DTC) B080B refers to a problem with the airbag system in your vehicle, specifically indicating a malfunction in the 'Driver's Seat Position Sensor.' This sensor is crucial as it helps determine the correct deployment of the airbag in the event of a collision. When the B080B code is triggered, it means that the vehicle's computer has detected an abnormality with the driver's seat position, which could lead to improper airbag deployment, increasing the risk of injury during an accident. Most commonly found in Chevrolet and GMC vehicles from 2015 to 2019, this code can be a cause for concern as it directly relates to safety features. Drivers may notice the airbag warning light illuminated on the dashboard, indicating a fault in the system. If left unaddressed, this issue could lead to serious safety risks in the event of an accident, where the airbag may not deploy correctly or at all. It's essential to address this code promptly, as driving with an unresolved airbag issue can jeopardize passenger safety. Regular diagnostics and maintenance can help in catching such issues early, ensuring that your vehicle's safety systems function as designed.

Symptoms

Common symptoms when B080B is present:

  • Airbag warning light stays illuminated on the dashboard, indicating a fault in the airbag system.
  • The driver's seat may not adjust properly or may feel loose, impacting overall comfort and safety.
  • Additional warning messages may appear on the vehicle's display, alerting the driver to a safety issue.
  • Inconsistent airbag deployment during routine safety checks or diagnostic scans.
  • Possible seat position memory loss, where the seat reverts to a default position unexpectedly.

Possible Causes

Most common causes of B080B (ordered by frequency):

  1. The most common cause of the B080B code is a faulty driver's seat position sensor, which accounts for around 60% of cases. This sensor can wear out or fail due to regular use or exposure to moisture.
  2. Another potential cause could be damaged wiring or poor connections in the seat adjustment harness, which can disrupt communication between the seat sensor and the vehicle's computer.
  3. Additionally, if the seat is improperly installed or has been removed and reinstalled without proper calibration, it may lead to the B080B code being triggered. Always ensure that a professional handles seat repairs.
  4. Less common but serious causes include issues with the airbag control module itself, which can lead to complete failure of the airbag system.
  5. A rare cause might be software glitches in the vehicle's computer, which can sometimes be resolved with a simple software update.
