What is C00F4?

DTC C00F4 is a diagnostic trouble code that indicates a problem with the vehicle's adaptive cruise control system. This code is often triggered in vehicles like the 2015-2018 Honda Accord and Toyota Camry. When this code appears, it typically points to issues with the radar sensor or the control module responsible for managing the adaptive cruise control functionalities. In practical terms, this means that your vehicle may have trouble maintaining a safe distance from the car in front of you when using cruise control, potentially leading to unsafe driving conditions. Furthermore, you may notice that your cruise control system becomes unresponsive or fails to engage properly. Ignoring this code can result in more severe issues down the line, including complete failure of the adaptive cruise control system, which can compromise your driving comfort and safety. Therefore, it is essential to address this code promptly to maintain the functionality and reliability of your vehicle's cruise control system.

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

Symptoms

Common symptoms when C00F4 is present:

  • The check engine light illuminates, indicating a fault in the adaptive cruise control system.
  • The adaptive cruise control system may fail to engage or disengage properly, leading to erratic vehicle speed control.
  • Drivers may experience difficulty in maintaining a safe following distance due to unresponsive cruise control features.
  • You might notice reduced fuel efficiency as the system struggles to maintain optimal speed.
  • In some cases, the vehicle may exhibit unusual braking behavior when attempting to adjust speed automatically.

Possible Causes

Most common causes of C00F4 (ordered by frequency):

  1. The most common cause of DTC C00F4 is a malfunctioning radar sensor, with a likelihood of about 50%. This sensor is crucial for the adaptive cruise control to gauge the distance from the vehicle ahead.
  2. Another frequent issue could be a faulty control module that processes the radar sensor's data, which can lead to a 30% chance of triggering this code.
  3. Wiring issues such as frayed wires or poor connections can also contribute to this code, and regular inspections can help prevent such occurrences.
  4. Less commonly, a misalignment of the radar sensor may cause the system to malfunction, leading to a risk of inaccurate distance readings.
  5. A rare but serious cause could be a software glitch in the vehicle's cruise control system, which may require a software update or reprogramming.
