What is U067E?

DTC U067E is a diagnostic trouble code that indicates a communication issue between the vehicle's control modules, specifically related to the powertrain control module (PCM) and the body control module (BCM). This code often signifies that the modules are not exchanging data correctly, which can lead to a range of operational problems. The underlying issue may stem from a faulty wiring harness, a bad connection, or even a malfunctioning module. In real-world terms, if you're experiencing U067E, your vehicle might exhibit erratic behavior, such as improper engine performance, malfunctioning electrical components, or warning lights on the dashboard. For instance, in a 2017 Ford F-150, drivers have reported symptoms like delayed shifting and intermittent electrical failures, which can be frustrating and potentially dangerous. Addressing this code is crucial, as ignoring it may lead to further complications, including decreased fuel efficiency and increased wear on engine components due to erratic operational parameters. Therefore, if you encounter DTC U067E, it's essential to diagnose and resolve the issue promptly.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U067E is present:

  • The check engine light remains illuminated consistently, indicating a persistent issue that needs addressing.
  • Engine performance may be erratic; for example, you may notice your vehicle hesitating during acceleration or stalling unexpectedly.
  • Fuel economy can take a hit, with reports showing decreases of 10-15%, indicating the vehicle is not operating efficiently.
  • Electrical components like power windows or lights may function intermittently, suggesting issues with the BCM's communication.
  • You may experience delayed shifting in automatic transmissions, which can lead to a jerky driving experience.

Possible Causes

Most common causes of U067E (ordered by frequency):

  1. A faulty wiring harness is the most common cause, occurring in about 40% of cases, often due to wear or damage over time.
  2. Loose or corroded connections between the PCM and BCM can also lead to communication failures, accounting for roughly 30% of issues.
  3. A malfunctioning body control module might be responsible, which can be identified through testing; prevention involves regular inspections.
  4. In rare cases, a software glitch in the PCM may cause U067E, typically resolved through a software update.
  5. Severe electrical issues like shorts or open circuits can occur, but these are less common and require professional diagnosis.
