What is C0DD6?

DTC C0DD6 is a diagnostic trouble code that indicates a problem within the vehicle's communication network, specifically linked to the Advanced Driver Assistance Systems (ADAS) or related modules. This code usually surfaces when the vehicle's onboard computer detects a malfunction in the communication process among various control modules, particularly in models like the 2016-2021 Ford Explorer and Fusion. The implications of this issue can range from minor inconveniences, such as warning lights illuminating on the dashboard, to more significant problems that affect the vehicle's safety features. If left unaddressed, C0DD6 may lead to reduced performance of the ADAS features, which include lane-keeping assist, adaptive cruise control, and automatic emergency braking. This can compromise the vehicle's overall safety and functionality. Drivers might notice symptoms such as erratic behavior of the steering or unexpected braking, potentially putting them at risk while driving. Hence, timely diagnosis and repair are crucial to ensure that these systems function correctly and to maintain vehicle safety and integrity.

Symptoms

Common symptoms when C0DD6 is present:

  • The check engine light or ADAS warning light stays on constantly, indicating a persistent issue that needs addressing.
  • Drivers may experience erratic steering responses, where the vehicle seems to steer itself unexpectedly or doesn't respond as anticipated during lane changes.
  • Fuel economy has decreased noticeably, with reports indicating drops of 5-10%, possibly due to the vehicle attempting to compensate for the malfunction.
  • Inconsistent performance of safety features, such as adaptive cruise control or emergency braking, which may engage or disengage unpredictably.
  • Dashboard alerts related to ADAS functions appear frequently, suggesting a failure in the communication network.

Possible Causes

Most common causes of C0DD6 (ordered by frequency):

  1. The most common cause of C0DD6 is a disconnected or damaged wiring harness, with a likelihood of around 40%. Regular checks can prevent this issue, especially after repairs or modifications.
  2. Another frequent cause is a malfunctioning control module, such as the ADAS ECU. This may lead to miscommunication between vehicle systems and requires a replacement or reprogramming to resolve.
  3. Corrosion in connectors or poor ground connections can also trigger this code, making up about 10% of cases. Ensure regular maintenance checks on these components to prevent such issues.
  4. Less common but serious causes include software glitches due to outdated firmware in the vehicle's control modules, which may require a dealer visit for updates.
  5. A rare cause could be a complete failure of the ADAS system, which might necessitate a full replacement of multiple components, leading to significant repair costs.
