What is B0981?

The B0981 diagnostic trouble code (DTC) is a specific error code that pertains to the vehicle's airbag system, particularly indicating a problem with the internal control module for the airbag. This code typically signifies an issue with the communication between the airbag module and the vehicle's onboard network. When B0981 is triggered, it often means that the airbag system may not function properly during a collision, posing a significant safety risk. Car owners may notice that the airbag warning light is illuminated on the dashboard, indicating that the system is compromised. This is particularly relevant for 2015-2020 Ford vehicles, including popular models such as the Ford F-150 and Ford Explorer, where airbag reliability is crucial for passenger safety. If left unaddressed, this issue can lead to the airbag failing to deploy during an accident, potentially resulting in serious injury or death. Therefore, it's essential for vehicle owners to understand the implications of the B0981 code and seek a thorough diagnostic assessment as soon as possible.

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

Symptoms

Common symptoms when B0981 is present:

  • The airbag warning light stays illuminated on the dashboard, indicating a malfunction in the airbag system.
  • You may hear a chime or beep when starting the vehicle, signaling a problem with the airbag system.
  • There is an increased risk of the airbag failing to deploy in the event of a collision.
  • You might notice other electronic issues, such as malfunctioning dashboard indicators or communication error messages.
  • The vehicle may exhibit erratic behavior in other electronic systems, reflecting the underlying communication issue.

Possible Causes

Most common causes of B0981 (ordered by frequency):

  1. The most common cause of B0981 is a malfunctioning airbag control module, which accounts for approximately 70% of cases. This can occur due to internal faults or manufacturing defects.
  2. Another common cause is damaged wiring or poor connections between the airbag module and the vehicle’s network. Corrosion or frayed wires can disrupt communication, leading to error codes.
  3. Faulty sensors within the airbag system can also trigger the B0981 code. If sensors fail to relay accurate information, the airbag control module may not function properly.
  4. Less common but serious causes include issues with the vehicle's onboard computer or software glitches that require reprogramming or replacement.
  5. A rare cause could be a complete failure of the airbag system due to a manufacturing defect, necessitating a full replacement of the airbag unit.
