U068E is frequently reported in 2015-2020 Ford vehicles. If you're driving models like the Ford F-150 or Ford Explorer, be especially vigilant, as these vehicles are known to experience this code.

How can I prevent U068E from happening again?

To prevent U068E, regularly inspect your vehicle's wiring and connections, keep your software updated, and address any warning lights or symptoms promptly to avoid larger issues.

What is U068E?

The diagnostic trouble code (DTC) U068E indicates a communication error between the vehicle's control modules, particularly in Ford models from 2015 to 2020. This error typically arises when one of the modules, such as the powertrain control module (PCM), fails to communicate properly with the others due to wiring problems, software glitches, or component failures. When this code appears, you may notice various issues including erratic behavior of vehicle systems, warning lights on the dashboard, or even performance problems like reduced power or increased fuel consumption. The presence of U068E can lead to more significant issues if not addressed promptly, as it affects the overall operational integrity of the vehicle. This code is mainly a concern for drivers who rely heavily on their vehicle for daily commuting or long-distance travel, as it can lead to unexpected breakdowns. Ignoring this code could not only worsen the problem but also potentially lead to more costly repairs down the line. Therefore, it's crucial to diagnose this issue accurately and undertake the necessary repairs to ensure optimal vehicle performance.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U068E is present:

  • The check engine light illuminates and remains on, indicating an underlying issue that needs to be resolved.
  • You may experience erratic behavior in various vehicle systems, such as the ABS or traction control system, which can lead to unsafe driving conditions.
  • Drivers often note a decrease in fuel efficiency, potentially losing 10-15% of fuel economy due to improper module communication.
  • Occasional engine stalling or hesitation during acceleration can occur, which might lead to dangerous situations on the road.
  • In some cases, the vehicle may enter 'limp mode,' significantly reducing power to prevent damage until the issue is addressed.

Possible Causes

Most common causes of U068E (ordered by frequency):

  1. The most common cause of U068E, occurring in about 65% of cases, is damaged wiring or poor connections that disrupt communication between modules.
  2. Another frequent cause, responsible for about 20% of occurrences, is software glitches in the vehicle's control modules, which can sometimes be resolved through updates.
  3. A third cause could be a failing control module itself, which requires replacement; regular inspections can help prevent this issue.
  4. Less common but serious causes include internal faults within the vehicle's CAN bus system, which can significantly impair vehicle functionality.
  5. In rare cases, environmental factors such as water intrusion or corrosion at connector points can lead to communication failures.
