You can use the GeekOBD APP to scan your vehicle for DTCs, retrieve freeze frame data, and perform a live data stream analysis to understand the performance of the collision avoidance system, helping you pinpoint the issue.

What vehicles are most commonly affected by C0FC1?

C0FC1 is often reported in 2016-2020 Ford Explorer models. Additionally, other vehicles with similar safety features may also experience this code, especially if they have been involved in accidents or sustained damage.

How can I prevent C0FC1 from happening again?

Regularly inspect your vehicle's wiring and sensors for damage, keep software updated, and ensure that the sensors are clean and unobstructed by debris or ice, especially in colder climates.

What is C0FC1?

The diagnostic trouble code (DTC) C0FC1 indicates a malfunction within the collision avoidance system, specifically related to sensors or wiring in vehicles. This code is often seen in 2016-2020 Ford Explorer models, where the collision avoidance system is integral for safety features like automatic emergency braking and adaptive cruise control. When C0FC1 is triggered, it suggests that the system has detected an issue with the functionality of the radar or camera sensors responsible for detecting obstacles. In practical terms, if this code appears, drivers may notice that safety features like collision warnings or automatic braking may not function properly, increasing the risk of accidents. It's crucial to address this issue promptly to ensure the safety systems operate as intended. Ignoring this code can lead to further complications in the vehicle's electrical systems and may result in costly repairs down the line. Regular maintenance checks and diagnostic scans using tools like the GeekOBD APP can help monitor for such issues before they escalate.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0FC1 is present:

  • Check engine light remains illuminated, signaling a persistent issue that requires immediate diagnosis.
  • Automatic emergency braking system does not engage when needed, leading to potential collision risks.
  • Adaptive cruise control may become unresponsive or fail to maintain a safe distance from other vehicles.
  • Dashboard warnings related to collision avoidance systems flash intermittently, indicating sensor malfunctions.
  • Inconsistent performance of lane-keeping assistance features, potentially leading to drifting in lanes.

Possible Causes

Most common causes of C0FC1 (ordered by frequency):

  1. Wiring issues in the sensor harness (60% likelihood) - Damaged or corroded wiring can prevent sensors from functioning correctly.
  2. Faulty radar or camera sensors (25% likelihood) - Sensors may fail due to physical damage or internal malfunctions.
  3. Software glitches in the collision avoidance system (10% likelihood) - Outdated software can cause communication errors between components.
  4. Less common cause: A malfunctioning central control module (3% likelihood) - Rarely, the module that processes sensor data may fail.
  5. Rare but possible cause: Environmental interference (2% likelihood) - Extreme weather conditions or obstructions can affect sensor performance.
