What is C0ED6?

The DTC C0ED6 is a diagnostic trouble code related to the vehicle’s powertrain control module (PCM) and indicates a communication issue within the vehicle's network. This code is commonly found in 2017-2021 Ford Fusion models, although it can appear in other makes and models that utilize similar communication protocols. When C0ED6 triggers, it usually suggests that there’s a malfunction in the CAN (Controller Area Network) which allows various modules in the car to communicate with each other. This problem may manifest due to damaged wiring, faulty connectors, or even issues with the PCM itself. If this code appears, you may notice that certain functionalities in your vehicle are impaired, such as the engine performance, transmission shifting, or even features related to safety systems. Ignoring this code can lead to more significant issues, including reduced fuel efficiency or complete loss of vehicle functionality, making it essential to address it promptly. Ensure to have a reputable diagnostic tool, like the GeekOBD APP, to accurately read the code and understand the context in which it occurred, as this can help pinpoint the specific issue more effectively.

Symptoms

Common symptoms when C0ED6 is present:

  • Check engine light remains illuminated, indicating a persistent issue that needs attention to avoid potential damage.
  • Engine performance may be erratic, showing signs of hesitation during acceleration or stalling unexpectedly.
  • Transmission may experience rough shifting or fail to engage properly due to communication errors affecting the vehicle's control modules.
  • Dashboard warning lights may illuminate, including indicators for traction control or anti-lock braking systems, suggesting broader electrical issues.
  • Increased fuel consumption as the engine management system struggles to optimize performance due to communication faults.

Possible Causes

Most common causes of C0ED6 (ordered by frequency):

  1. The most common cause of C0ED6 is damaged wiring within the vehicle's CAN network, estimated to occur in about 50% of cases. Over time, these wires may suffer from wear and tear, leading to poor communication.
  2. A malfunctioning powertrain control module (PCM) can also trigger this code. If the PCM is failing, it may not send or receive signals correctly, which is particularly common in vehicles over 75,000 miles.
  3. Corroded connectors are another frequent cause; moisture and dirt can infiltrate connectors, leading to poor electrical connections.
  4. Less common but serious causes include a faulty CAN bus, which can disrupt communication between multiple electronic control units, potentially leading to severe operational failures.
  5. Rarely, issues with the vehicle’s battery or alternator can affect electrical systems, creating communication errors that trigger DTC C0ED6.
