What is C0ACA?

The diagnostic trouble code (DTC) C0ACA is specific to certain Ford models, most notably the 2015-2018 Ford F-150. This code indicates an issue with the vehicle's advanced driver assistance systems (ADAS), specifically related to the Adaptive Cruise Control (ACC) system. When this code is triggered, it signifies that the system has detected a malfunction that affects the vehicle's ability to maintain speed automatically or adjust speed based on traffic conditions. In practical terms, this could mean that drivers may notice their cruise control stops working, or the associated warning lights may illuminate on the dashboard. If left unresolved, this issue can lead to compromised safety features, particularly in scenarios where adaptive functions are crucial, such as highway driving. Additionally, while the vehicle can still be driven, the absence of functioning adaptive cruise could mean a less convenient driving experience, particularly in stop-and-go traffic. Therefore, addressing this code promptly is critical for both safety and convenience.

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

Symptoms

Common symptoms when C0ACA is present:

The check engine light or warning indicators related to cruise control may remain on continuously.
Drivers may experience sudden loss of cruise control functionality, noticing that the system fails to engage or maintain set speeds.
Fuel economy may suffer due to manual acceleration and braking, with reports of decreased efficiency by 10-15%.
Unusual sounds or vibrations when attempting to activate cruise control, indicating potential mechanical issues.
In some cases, drivers might notice erratic speed adjustments when attempting to use adaptive cruise control.

Possible Causes

Most common causes of C0ACA (ordered by frequency):

{'cause': 'Faulty Adaptive Cruise Control Module', 'likelihood': 'Approximately 45%', 'details': 'The module that controls the adaptive cruise system may malfunction due to electrical issues or wear over time.'}
{'cause': 'Faulty Radar Sensor', 'details': 'The radar sensor responsible for detecting obstacles or vehicles ahead may be misaligned or damaged, affecting system functionality.'}
{'cause': 'Wiring Issues', 'details': 'Corroded or damaged wiring harnesses can interrupt signals between the cruise control module and other components.'}
{'cause': 'Software Glitches', 'details': "Sometimes the issue can stem from outdated software that fails to communicate properly with the vehicle's systems."}
{'cause': 'Mechanical Failures', 'details': 'Less commonly, mechanical components associated with the cruise control may fail, impacting overall operation.'}
