What is C0B52?
The C0B52 code is a diagnostic trouble code that indicates a malfunction in the communication network of the vehicle's advanced driver-assistance systems (ADAS), specifically related to the front radar sensor. This code is most commonly found in 2015 to 2020 Ford models, such as the Ford F-150 and Ford Explorer. When the C0B52 code is triggered, it means that the vehicle's onboard computer has detected an issue with the signal from the radar sensor that supports features like adaptive cruise control and collision avoidance. This can lead to a significant impact on safety, as these systems rely on accurate readings from the radar to function properly. If left unaddressed, the malfunction could degrade performance over time, leading to potential safety risks for the driver and passengers. Understanding this code is crucial for proper vehicle maintenance, as it can also affect other related systems. It's essential to have a qualified technician perform diagnostics to determine the exact cause of the issue and implement the necessary repairs to ensure optimal vehicle performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0B52 is present:
- Check engine light stays on constantly, indicating a fault in the radar system.
- Adaptive cruise control fails to engage or operate intermittently, affecting driving convenience.
- Collision warning system is disabled, increasing the risk of accidents due to lack of alert notifications.
- Vehicle may exhibit unusual braking behavior, especially when approaching objects.
