What is B1068?
DTC B1068 is a diagnostic trouble code that signifies a malfunction within the airbag or supplemental restraint system (SRS). Specifically, it indicates an issue with the occupant classification system, which is responsible for determining whether the passenger airbag should be activated based on the weight and occupancy of the passenger seat. This code can trigger the airbag warning light on your dashboard, alerting you to a potential safety concern. In practical terms, if this code is present, your vehicle's airbag system may not function correctly in the event of a collision, which significantly compromises passenger safety. For instance, in 2015-2019 Ford Fusions, this issue is often linked to faulty sensors or wiring in the seat. If you ignore this code, you risk not only potential injury in an accident but may also face expensive repair bills later on if the problem escalates. It's crucial to address this trouble code promptly to ensure your vehicle remains safe and compliant with safety regulations.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B1068 is present:
- The airbag warning light remains illuminated on the dashboard, indicating that there's a problem with the airbag system.
- Frequent chimes or alerts from the vehicle indicating a malfunction of the airbag system, which may distract the driver.
- Inconsistent airbag deployment during crash simulations, which can be observed through diagnostic tools or during safety inspections.
- Passenger seat sensors may fail to recognize if a child or adult is seated, leading to incorrect airbag activation.
- Bumper-to-bumper accident reports may show increased incidents of airbag non-deployment when this code is present.
Possible Causes
Most common causes of B1068 (ordered by frequency):
- Faulty occupant classification sensor is the most common cause, accounting for approximately 60% of cases. This sensor determines if the passenger seat is occupied and whether the airbag should deploy.
- Wiring issues such as frayed or damaged wires can also trigger this code, often due to wear and tear from regular use, making up about 25% of issues.
- Corrosion at the connectors or poor electrical contacts can lead to intermittent faults, contributing to around 10% of cases. Proper maintenance and inspections can help prevent this.
- Less common but serious causes include a malfunctioning airbag control module, which may require replacement if found defective.
- In rare cases, software glitches in the vehicle's onboard computer system could falsely trigger this code, though this is less than 5% of occurrences.
