What is C0F67?
DTC C0F67 indicates a fault in the vehicle's advanced driver-assistance systems (ADAS), particularly related to the lane departure warning system. When this code is triggered, it suggests that the system is unable to determine the vehicle's position accurately within the lane, which could result from sensor malfunctions, wiring issues, or software problems. This code is especially prevalent in models like the 2015-2018 Honda Accord and Toyota Camry, where ADAS features are more common. The implications of this code can be serious, potentially affecting the vehicle's safety features, leading to unintended lane departures, which can increase the risk of accidents. If you see this code, it's crucial to address it promptly, as ignoring it might compromise not only your vehicle's functionality but also your safety on the road. Drivers might notice the lane departure warning light activating intermittently or not at all, indicating that the system isn't functioning as intended. Overall, C0F67 signifies a need for a thorough diagnostic check to ensure all components are working correctly and safely.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0F67 is present:
- The lane departure warning light may illuminate on the dashboard, indicating a malfunction in the system.
- You might experience irregular beeping or alerts when the vehicle drifts slightly, even when the road is straight.
- Drivers often report a decrease in overall vehicle safety features, which could lead to unfamiliar or dangerous driving situations.
- There may be instances where the system fails to provide feedback, such as warning the driver when drifting out of the lane.
- In some cases, vehicle stability could be compromised, leading to unintended lane changes.
Possible Causes
Most common causes of C0F67 (ordered by frequency):
- The most common cause is a malfunctioning front-facing camera or radar sensor, with a likelihood of about 60%. These sensors may become misaligned or damaged.
- Another frequent issue is wiring problems, such as frayed or corroded wires, which can disrupt communication between the sensors and the vehicle’s computer system.
- Software glitches in the ADAS may also trigger this code, often resolved through a software update from the manufacturer.
- Less common but serious causes include significant accidents that can physically damage the sensor or misalign the ADAS system.
- A rare cause could be interference from aftermarket devices or accessories that disrupt the vehicle's electronics.
