What is B0241?

Diagnostic Trouble Code (DTC) B0241 relates to a malfunction in the front passenger airbag system. This code is primarily triggered when the airbag control module detects an issue with the passenger airbag's deployment circuit or its associated sensors. In practical terms, if your vehicle throws this code, it could mean that the passenger airbag may not deploy in the event of a crash, posing a significant safety risk to occupants. This code is often accompanied by the 'Airbag' warning light illuminating on the dashboard, making it crucial to address promptly. Common symptoms include a lack of functionality in the airbag system, which could lead to severe consequences in the event of an accident. For vehicle owners, especially of models like the Honda Civic (2015-2018), it’s essential to understand that ignoring this code could lead to costly repairs later on, as well as jeopardizing the safety of passengers. Addressing the issue typically involves inspecting the wiring harness, checking for faults in the airbag module, and ensuring that the sensors are operational. It's advisable to consult a professional technician for a thorough diagnosis and repair.

Symptoms

Common symptoms when B0241 is present:

  • The airbag warning light on the dashboard remains illuminated, indicating a malfunction in the airbag system.
  • You may notice that the passenger airbag indicator shows 'off' even when a passenger is seated, suggesting a sensor issue.
  • In some cases, the vehicle may experience delays in airbag deployment during simulated crash tests, which can be verified through diagnostic tools.
  • Occasional electrical faults may occur, affecting the vehicle's ability to communicate with its onboard computer systems.
  • If the issue persists, you might experience erratic behavior in other safety systems like seatbelt warnings or automatic braking.

Possible Causes

Most common causes of B0241 (ordered by frequency):

  1. The most common cause is a faulty airbag module, which accounts for approximately 60% of cases. This module can fail due to age or exposure to moisture.
  2. Wiring issues, such as damaged or corroded wires in the airbag circuit, can also trigger this code. It's crucial to check harness connectors, especially under the passenger seat.
  3. Sensor failures, particularly in the weight sensor located in the passenger seat, may prevent the system from recognizing when someone is sitting there, leading to a deactivated airbag.
  4. Less commonly, software glitches in the vehicle's onboard computer could cause false readings, necessitating a software update or reprogramming.
  5. In rare instances, aftermarket modifications or repairs may inadvertently interfere with the airbag system, resulting in this code being triggered.
