What vehicles are most commonly affected by B107C?

The B107C code is commonly found in models such as the 2015-2018 Honda Accord and other vehicles equipped with similar airbag systems. Regular maintenance is essential to prevent issues.

How can I prevent B107C from happening again?

Regular inspections of the seating area and wiring, along with prompt attention to any signs of wear or damage, can help prevent the recurrence of B107C. Additionally, keeping up with scheduled vehicle maintenance can mitigate risks.

What is B107C?

The Diagnostic Trouble Code (DTC) B107C is primarily related to the body control module (BCM) and indicates a fault in the passenger presence detection system. This system is designed to ensure that the airbag deploys appropriately based on passenger weight and presence. When the B107C code is triggered, it typically means that the BCM has detected an issue, such as an open or short circuit in the passenger seat sensor or the wiring connection. This can lead to safety concerns, as the airbag may not deploy correctly in the event of a collision, potentially putting passengers at risk. The presence detection system is crucial for optimizing airbag deployment, which can vary based on the weight and position of the occupant. If you own a 2015-2018 Honda Accord, it’s important to address this code promptly to ensure your vehicle’s safety features function as intended. Ignoring this code could result in costly repairs in the long run, as well as pose a significant safety risk during accidents. Always consult with a qualified technician or utilize diagnostic tools like the GeekOBD APP to retrieve more detailed information about the fault.

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

Symptoms

Common symptoms when B107C is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a fault in the airbag system.
  • You may notice that the passenger seat indicator does not change when someone sits in the seat, suggesting a malfunction.
  • In some cases, the vehicle may emit a warning chime when starting, indicating that the airbag system requires servicing.
  • Unusual behavior from the passenger airbag system, such as it being disabled even when a passenger is present.
  • You might experience an inconsistent airbag deployment during tests, as the system fails to recognize the passenger.

Possible Causes

Most common causes of B107C (ordered by frequency):

  1. The most common cause of the B107C code is a faulty passenger seat occupancy sensor, with a likelihood of around 60%. This sensor detects the weight of the passenger to determine if the airbag should deploy.
  2. Another frequent cause is damaged wiring or connectors related to the BCM or sensor, which can account for about 25% of cases. Corrosion or wear can lead to poor connectivity.
  3. Regular wear and tear on vehicle components can lead to issues; preventative maintenance can help, reducing the likelihood of this code appearing.
  4. A less common but serious cause is a malfunctioning BCM, which could result in significant safety risks if not addressed promptly.
  5. In rare cases, software issues within the BCM could also trigger the B107C code, requiring software updates or reprogramming.
