What is C0ACC?

The C0ACC code is a diagnostic trouble code that indicates a fault in the vehicle's adaptive cruise control system. This system is designed to maintain a set speed while automatically adjusting the vehicle’s speed to maintain a safe following distance from the vehicle ahead. When the C0ACC code is triggered, it generally indicates that there is a malfunction in the adaptive cruise control system, which may be due to various factors such as sensor issues, wiring problems, or software malfunctions. For owners of vehicles like the 2015-2020 Ford Explorer, this could mean that the cruise control feature may not function correctly, leading to potential safety concerns. Drivers may notice symptoms such as the cruise control not engaging or disengaging unexpectedly, or the system failing to maintain speed. It is crucial to address this code promptly as it may affect the overall driving experience and safety. Ignoring the C0ACC code could lead to further complications and increased repair costs down the line, making it essential to diagnose and rectify the issue as soon as possible.

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

Symptoms

Common symptoms when C0ACC is present:

  • The adaptive cruise control light on the dashboard stays illuminated, indicating a persistent issue.
  • Cruise control fails to engage or disengages suddenly while driving, leading to inconsistent speed management.
  • Drivers may experience erratic speed fluctuations, as the system struggles to maintain the set speed.
  • Unusual noises from the steering column or dashboard when attempting to use cruise control.
  • Increased fuel consumption due to improper speed management by the cruise control system.

Possible Causes

Most common causes of C0ACC (ordered by frequency):

  1. Faulty speed sensors, which account for about 40% of C0ACC occurrences, can lead to inaccurate speed readings and affect the cruise control's functionality.
  2. Damaged wiring or connectors in the cruise control system, which can disrupt signals and cause system failures.
  3. Software glitches in the vehicle's control module may occasionally trigger the C0ACC code, warranting a software update from the manufacturer.
  4. Less common but serious issues such as a malfunctioning brake pedal switch can deactivate cruise control, posing safety risks.
  5. Rarely, external factors like a faulty throttle position sensor can contribute to the C0ACC code being triggered.
