What vehicles are most commonly affected by B0190?
B0190 is frequently reported in models like the 2010-2015 Honda Accord, 2011-2014 Ford Explorer, and 2013-2016 Chevrolet Malibu. Always check for any manufacturer recalls or technical service bulletins (TSBs) related to the airbag system that could provide additional insights.
How can I prevent B0190 from happening again?
To prevent B0190 from recurring, perform regular maintenance checks on your airbag system, including visual inspections of wiring and connectors. Avoid modifications that may affect the airbag system and ensure that any repairs are completed by qualified professionals.
What is B0190?
The diagnostic trouble code (DTC) B0190 is associated with the airbag system, indicating that there is a malfunction in the airbag control module or its associated components. This code typically triggers when the vehicle's onboard diagnostic system detects an issue that could affect the operation of the airbags in the event of an accident. When the B0190 code appears, it often means that the airbag warning light will illuminate on the dashboard, signaling that the system may not deploy correctly during a crash. This is a high-priority issue as it directly impacts passenger safety. Commonly found in vehicles like the 2010-2015 Honda Accord, the B0190 can stem from various issues such as faulty sensors, damaged wiring, or a malfunctioning airbag control module itself. If not addressed, this issue could lead to a situation where the airbags do not deploy, increasing the risk of injury in an accident. Understanding the implications of this code is crucial for any car owner, as it highlights the importance of regular maintenance and immediate attention to warning lights. Ignoring the B0190 code might not only compromise vehicle safety but could also lead to costly repairs if the problem worsens over time.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0190 is present:
- The airbag warning light is illuminated on the dashboard, indicating a potential issue with the airbag system and requiring immediate attention.
- Passengers may experience an increase in discomfort due to faulty seat sensors that may fail to detect occupancy, affecting airbag deployment.
- In some cases, the vehicle may display a diagnostic message on the infotainment system, alerting the driver to airbag system issues.
- You might notice that other safety features, like seatbelt pretensioners, are not functioning correctly, which is another sign of a malfunctioning airbag system.
- The vehicle's performance could be compromised, as the airbag system often interacts with other safety systems, leading to possible irregularities.
Possible Causes
Most common causes of B0190 (ordered by frequency):
- The most common cause of the B0190 code is a faulty airbag control module, with a likelihood of about 40%. This may occur due to wear and tear or electrical issues.
- Another common cause, accounting for around 30% of cases, is damaged wiring or poor connections within the airbag system, which can lead to intermittent faults.
- Faulty seat belt tension sensors represent about 20% of the issues that trigger this code; these sensors can malfunction due to moisture or physical damage.
- Less common but serious is the deployment of the airbags due to a previous accident, which could have compromised the airbag system's integrity.
- A rare cause could be software issues within the vehicle's onboard computer, which may require dealer-level diagnostics and updates.
