What is C0C16?
The DTC C0C16 code indicates that there is a problem with the vehicle's Active Park Assist system, primarily found in Ford models from 2016 to 2020. This code is triggered when the onboard diagnostics detect a fault within the system responsible for assisting drivers in parking maneuvers. Commonly found in vehicles like the Ford Fusion and Ford Explorer, the Active Park Assist system uses sensors to detect parking spaces and guide the vehicle into them. When the C0C16 code appears, it typically signifies that the system has failed to operate as intended. This could manifest as the system being unable to detect available parking spaces or the steering assist not functioning correctly during parking attempts. If left unaddressed, it could impact the vehicle's safety features, making parking more challenging and potentially leading to collisions. It's important for vehicle owners to understand that this issue can originate from various sources, including faulty sensors, wiring issues, or software malfunctions. Proper diagnosis and repair are essential to restore the functionality of the Active Park Assist system and ensure safe driving conditions.
