Regular cleaning of the radar sensor, avoiding aftermarket installations that may interfere with the vehicle's electrical systems, and having software updates performed can help keep your ADAS functioning properly.

What is C06AA?

DTC C06AA is a diagnostic trouble code that typically indicates a malfunction related to the vehicle's advanced driver-assistance systems (ADAS), particularly the adaptive cruise control and collision avoidance features. When this code appears, it suggests there may be an issue with the sensors or modules associated with these systems, which are crucial for ensuring safe driving conditions. For instance, in models like the 2015-2018 Ford Explorer, this could be due to a malfunctioning radar sensor or a software glitch in the system's control module. This code can lead to diminished performance of the vehicle’s safety features, increasing the risk of accidents. In simple terms, if you see this code, it means that your vehicle's ability to assist you while driving could be compromised, and you should have it checked out promptly. Ignoring this code may not only affect your driving experience but also potentially lead to costly repairs down the road. In summary, DTC C06AA serves as a warning that drivers should not take lightly, as it can have implications for both safety and vehicle functionality.

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

Symptoms

Common symptoms when C06AA is present:

  • The check engine light or warning light for the ADAS systems remains illuminated.
  • Adaptive cruise control may fail to engage or disengage correctly, making driving less convenient and potentially unsafe.
  • Increased difficulty in using collision avoidance features, which may lead to anxiety during highway driving.
  • The vehicle may exhibit erratic behavior when attempting to activate parking assist or lane-keeping features.
  • Sensors may provide inaccurate readings, affecting the overall safety of the vehicle.

Possible Causes

Most common causes of C06AA (ordered by frequency):

  1. The most common cause of DTC C06AA is a faulty radar sensor, which can be responsible for up to 60% of occurrences. This sensor is vital for adaptive cruise control and collision avoidance systems, and its failure can lead to a complete system shutdown.
  2. A malfunctioning control module is the second most common cause. This component processes input from various sensors and can develop issues due to software glitches or electrical faults.
  3. A dirty or obstructed sensor can lead to false readings. Regular maintenance and cleaning of the sensors can prevent this issue.
  4. Less common causes include wiring harness issues, where frayed or damaged wires can interrupt the signal between the sensor and the control module.
  5. A rare but possible cause is the installation of aftermarket accessories that interfere with the vehicle’s electrical system, potentially causing DTC C06AA to trigger.
