What is B0828?
The DTC B0828 error code indicates a fault with the airbag sensor, specifically related to the side-impact sensor circuit or its signal. This code is commonly found in vehicles such as the 2010-2018 Ford Fusion, as well as various models from manufacturers like Mazda and Lincoln during similar production years. When this code is triggered, it suggests that the airbag system has detected an issue that could prevent airbags from deploying properly in the event of a collision. The side-impact sensors are crucial for the airbag system's functionality, as they assess the severity of an accident to deploy the appropriate airbags. A malfunction can lead to non-deployment during an accident, significantly increasing the risk of injury. It's essential for vehicle owners to address this code promptly to ensure safety features are operational. Diagnostic steps involve using an OBD2 scanner to confirm the code, checking the wiring and connectors for damage, and testing the sensor itself. If left unresolved, this issue could lead to safety recalls and expensive repairs down the line. Taking immediate action, especially if the airbag warning light is illuminated, is vital for maintaining vehicle safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0828 is present:
- Airbag warning light stays illuminated on the dashboard, indicating a malfunction in the airbag system.
- Inability of airbags to deploy during a crash, which is critical for passenger safety.
- Increased likelihood of the vehicle failing safety inspections due to airbag system issues.
- Potential issues with seatbelt pretensioners not functioning correctly, leading to reduced safety.
- Unusual noises or malfunctions from the airbag control module, indicating deeper electrical issues.
Possible Causes
Most common causes of B0828 (ordered by frequency):
- The most common cause is a faulty side-impact sensor, with a likelihood of about 60%. This can occur due to impact damage or electrical failure.
- Wiring issues or corroded connectors are the second most common cause, often due to moisture intrusion or wear over time, occurring in approximately 25% of cases.
- A malfunctioning airbag control module can also trigger the B0828 code, though this is less common, accounting for about 10% of incidents.
- Less common but serious causes include a complete failure of the airbag system, which could lead to costly repairs.
- Rare causes may involve software glitches in the vehicle's computer systems, which can sometimes be resolved with a firmware update.
