What is C0B61?
The diagnostic trouble code (DTC) C0B61 indicates a fault related to the vehicle's advanced driver assistance systems (ADAS), primarily concerning the radar sensor or related components. This code is particularly prevalent in models like the 2015-2020 Ford Explorer, where the adaptive cruise control and collision avoidance systems rely heavily on accurate data from the radar sensor. When C0B61 is triggered, it typically signifies a malfunction in the system communication or a fault in the radar sensor itself. In practical terms, this means your vehicle's safety features may not function as intended, potentially jeopardizing driver and passenger safety. If your car has this code, you might notice that features such as adaptive cruise control fail to activate or operate erratically. Long-term implications include increased risk while driving and possible failure of the vehicle's safety systems, which can lead to costly repairs if neglected. Therefore, addressing this code promptly is crucial for maintaining vehicle safety and reliability.
