Regular maintenance is key. Ensure that the airbag system is inspected during routine service, avoid modifications that could interfere with airbag functionality, and promptly address any warning lights or symptoms.

What is B0654?

DTC B0654 indicates a fault with the airbag sensor circuit, which can lead to the airbag system not functioning properly in the event of an accident. This code is triggered when the vehicle's onboard diagnostic system detects an issue with the airbag control module's communication with the sensors. Airbags are critical safety features designed to deploy upon impact, protecting passengers from severe injuries. When B0654 is present, it may signify an open or short circuit in the wiring, a malfunctioning airbag sensor, or issues within the airbag control module itself. Essentially, the vehicle's airbag system may not deploy in a crash, which significantly increases the risk of injury. Common models affected by this code include the 2010-2015 Ford Fusion and the 2011-2016 Chevrolet Cruze. Owners should address this code promptly to ensure their airbag system remains operational, as ignoring it could lead to potentially life-threatening outcomes during an accident. Additionally, some vehicles may illuminate the 'Airbag' warning light on the dashboard, indicating that the system is compromised. Regularly checking the airbag system during vehicle maintenance can help preemptively identify issues associated with DTC B0654.

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

Symptoms

Common symptoms when B0654 is present:

  • The airbag warning light is illuminated on the dashboard, indicating a fault in the airbag system that requires immediate attention.
  • The vehicle may experience intermittent issues with the airbag system, potentially failing to deploy during a collision, posing significant safety risks.
  • You may notice warning chimes or alerts when starting the vehicle, suggesting that the airbag system is not functioning correctly.
  • In some cases, the vehicle's electronic stability control system may also be affected, which can lead to decreased handling and safety.
  • Drivers may feel a sense of unease or insecurity while driving, knowing that the airbag system is compromised and could fail in an accident.

Possible Causes

Most common causes of B0654 (ordered by frequency):

  1. The most common cause of B0654 is a faulty airbag sensor, which occurs in about 60% of cases. This may happen due to wear and tear or physical damage during an accident.
  2. Another likely cause is damaged wiring or connectors in the airbag system, which can occur due to corrosion or improper installation, accounting for 25% of cases.
  3. A malfunctioning airbag control module can also trigger this code, particularly in older vehicles; however, this is less common and occurs in about 10% of cases. Regular inspections can help identify potential issues.
  4. Less commonly, a failed or incorrectly installed aftermarket accessory, such as a steering wheel cover, can interfere with the airbag system, although this is rare.
  5. In rare instances, software issues in the vehicle's control unit may cause false readings, resulting in the B0654 code being triggered without any physical issues present.
