What is C00B5?

DTC C00B5 is a diagnostic trouble code indicating an issue with the Adaptive Cruise Control (ACC) system in specific Ford vehicles, particularly from the 2016 to 2020 model years. This code can arise due to various reasons, including malfunctioning sensors responsible for detecting vehicle speed and distance. When the ACC system is compromised, it can lead to safety concerns, as it may not function correctly, potentially affecting your vehicle's ability to maintain a set speed or distance from the car ahead. Car owners may notice the cruise control feature becoming erratic or non-functional, which can lead to increased stress during long drives or highway travel. Since this system is designed to enhance driving comfort and safety, it's crucial to address any issues promptly. Neglecting a C00B5 code could lead to the ACC system becoming entirely inoperative, resulting in higher repair costs if further damage occurs. Therefore, understanding and diagnosing this code is essential for maintaining both the functionality and safety of your vehicle.

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

Symptoms

Common symptoms when C00B5 is present:

  • The Adaptive Cruise Control light on your dashboard remains illuminated, indicating a persistent issue.
  • The cruise control feature may disengage unexpectedly or fail to engage at all, leading to frustration during highway driving.
  • You may experience erratic acceleration or deceleration when attempting to use cruise control, which can create safety concerns.
  • The vehicle may display other warning lights, such as the check engine light, alongside the ACC warning.
  • In some cases, the vehicle’s speed may not stabilize correctly, leading to fluctuations that can be alarming during long drives.

Possible Causes

Most common causes of C00B5 (ordered by frequency):

  1. The most common cause of C00B5 is a faulty cruise control module, with a likelihood of around 45%. This module is responsible for processing inputs from various sensors.
  2. Another common cause is malfunctioning radar sensors, which can lead to incorrect distance measurements and affect the ACC system's performance.
  3. Wiring issues, such as frayed or corroded connections, can also contribute to this code, emphasizing the importance of regular vehicle inspections.
  4. Less common but serious causes include software glitches in the vehicle's onboard computer, which might require an update or reprogramming.
  5. In rare instances, damage to the vehicle's front fascia or bumper can affect sensor placement, leading to erroneous readings.
