What vehicles are most commonly affected by B0923?

B0923 is frequently found in 2015-2019 Ford models and certain Chrysler vehicles. Always check for any recalls or Technical Service Bulletins (TSBs) related to the airbag system.

How can I prevent B0923 from happening again?

Regularly inspect your vehicle's airbag system during service intervals, keep wiring dry and clean, and avoid aftermarket modifications that could interfere with the airbag system.

What is B0923?

The diagnostic trouble code (DTC) B0923 refers to a malfunction in the airbag sensor circuit, specifically indicating a fault in the driver's airbag circuit. This code is particularly common in 2015 to 2019 Ford and Chrysler vehicles, where the airbag system is responsible for deploying airbags in the event of a collision. When the vehicle's onboard diagnostic system detects an issue with the airbag sensor, it triggers this code, often accompanied by the illumination of the airbag warning light on the dashboard. The implications of a B0923 code can be serious, as it suggests that the airbag may not deploy during an accident, which can significantly increase the risk of injury. This code can stem from a variety of issues, such as a faulty sensor, damaged wiring, or a failed control module. It's crucial for car owners to address this code promptly to ensure their safety and the proper functioning of the airbag system. Ignoring this issue could lead to dangerous situations where the airbag system may not activate when needed, rendering the vehicle less safe in the event of a crash.

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

Symptoms

Common symptoms when B0923 is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a fault in the airbag system.
  • The vehicle may experience issues during inspection, as mechanics will note the airbag system is not functioning correctly.
  • Inconsistent airbag deployment in crash simulations, which can be tested during vehicle diagnostics.
  • A noticeable delay or failure in the airbag system self-check, which can be observed during vehicle start-up.
  • Unusual noises from the steering column area, suggesting potential wiring issues related to the airbag system.

Possible Causes

Most common causes of B0923 (ordered by frequency):

  1. A defective airbag sensor is the most common cause, accounting for approximately 60% of cases. These sensors can fail due to age or damage, impacting their ability to communicate with the airbag control module.
  2. Wiring issues such as frayed wires or poor connections are the second most common cause. These problems can arise from wear and tear or improper installation during repairs, leading to intermittent faults.
  3. Corrosion in the connectors can lead to poor electrical contact, contributing to B0923. Regular inspections of the airbag system can help prevent this.
  4. Less common, but serious, is a malfunctioning airbag control module, which could prevent the system from functioning properly. This issue may require replacement of the module.
  5. A rare cause could be software issues within the vehicle's onboard computer. This might require a software update from the manufacturer to resolve.
