The most common cause of B0335 is a faulty airbag sensor, which can cost between $200 - $400 to replace. Other causes include issues with wiring and the airbag control module, with costs varying based on the extent of the repair needed.
Can I drive my car with B0335 or should I stop immediately?
It's not advisable to drive your vehicle with the B0335 code present, as this indicates a potential failure in the airbag system. Driving without a functioning airbag system increases the risk of injury in an accident.
How can I diagnose B0335 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan your vehicle for diagnostic trouble codes and view freeze frame data that provides context for the B0335 code. This will help you understand when the issue occurred and any other related codes that may be present.
What vehicles are most commonly affected by B0335?
The B0335 code is commonly found in vehicles like the 2003-2010 Honda Accord, 2006-2014 Honda Civic, and 2004-2009 Acura TSX. If you own one of these models, be sure to monitor your airbag system closely.
How can I prevent B0335 from happening again?
Regular maintenance is key. Make sure to check the airbag system during routine inspections, avoid modifications to the vehicle's electrical system without professional help, and keep the vehicle dry to prevent sensor corrosion.
What is B0335?
The diagnostic trouble code B0335 indicates a malfunction in the airbag sensor circuit. This code is specifically associated with issues related to the driver's airbag deployment system. In simple terms, your vehicle's airbag system is designed to deploy in the event of a crash, and if there's a problem with the sensor circuit, it may not function correctly. This can lead to several consequences, including the airbag not deploying in an accident, which significantly increases the risk of injury. The B0335 code may trigger the airbag warning light on the dashboard, alerting you to a potential safety issue. It's crucial to address this code promptly, as airbag malfunctions can compromise your safety and that of your passengers. Common symptoms associated with this code may include the airbag warning light being illuminated and potential fault messages on your vehicle's onboard diagnostics. Diagnosing the issue typically involves using an OBD2 scanner, like the GeekOBD APP, to retrieve the code and assess the underlying problems. Ignoring this issue can lead to costly repairs down the line, especially if the airbag system malfunctions during an accident.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0335 is present:
- The airbag warning light on your dashboard stays illuminated, indicating a fault in the system.
- You may notice that the seat belt reminder chimes are malfunctioning or not activating correctly.
- In some cases, you might experience erratic behavior in other electronic systems, such as the dashboard lights flickering.
- There could be a noticeable delay in the airbag deploying during tests or simulations.
- You may receive a warning message on your OBD2 scanner indicating 'airbag system malfunction'.
Possible Causes
Most common causes of B0335 (ordered by frequency):
- The most common cause of the B0335 code is a faulty airbag sensor, accounting for about 60% of cases due to wear and tear or exposure to moisture.
- Wiring issues or corrosion in the airbag sensor circuit are another common cause, typically affecting 25% of reported cases, often seen in older vehicles.
- A malfunctioning airbag control module can also trigger this code, with a likelihood of around 10%. Regular maintenance can help prevent this.
- Less commonly, a crash impact sensor that has been damaged may lead to this code, which could account for around 3% of cases.
- In rare instances, software issues or updates could lead to false readings, affecting about 2% of vehicles.
