What is U07E0?

The diagnostic trouble code (DTC) U07E0 indicates a communication issue within the vehicle's control modules, specifically related to the vehicle's network. This code is often seen in Ford models from 2016 to 2020, where the vehicle's central computer is unable to effectively communicate with other modules like the powertrain control module (PCM) or the body control module (BCM). The implications of this code can range from minor inconveniences, such as warning lights on the dashboard, to more severe issues that can affect vehicle performance and safety. When the U07E0 code is triggered, drivers may experience unexpected performance drops, issues with electronic features, or even problems starting the vehicle. It's essential to address this code promptly, as ignoring it could lead to more complex issues that may result in costly repairs down the line. Understanding how this code interacts with your vehicle's systems can help you take the right steps to diagnose and fix the problem, ensuring your vehicle runs smoothly and safely.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U07E0 is present:

  • Check engine light stays on constantly, indicating an ongoing issue that requires diagnosis.
  • Engine hesitates during acceleration, which may lead to potential safety issues in traffic.
  • Fuel economy decreased by 10-15%, which can noticeably impact your monthly fuel expenses.
  • Loss of power steering functionality, making the vehicle harder to control and increasing safety risks.
  • Malfunctioning electronic features, such as windows or locks, which may stop responding as expected.

Possible Causes

Most common causes of U07E0 (ordered by frequency):

  1. The most common cause is a faulty wiring harness or connector related to the control modules, which has a likelihood of about 40%. Damaged or corroded connections can interrupt communication.
  2. The second most common cause involves software glitches in the vehicle's control modules. Regular updates or factory resets may resolve these issues, but can be overlooked during routine maintenance.
  3. A third cause could be a dead battery or weak battery connections, which can lead to insufficient power being supplied to the modules, causing communication failures.
  4. Less commonly, a short circuit within the control module itself can occur, which may require module replacement and is often more expensive to fix.
  5. A rare but possible cause is a manufacturing defect in the control modules, which might be covered under warranty if identified early.
