What is U068F?

The DTC U068F is a diagnostic trouble code that indicates a communication issue between the vehicle's body control module (BCM) and other control modules. When this code is triggered, it generally means that the BCM is not receiving or sending data properly to one or more of the vehicle's electronic systems. This can lead to various electronic malfunctions, including issues with lighting, power accessories, and even the vehicle's starting system. Owners of vehicles like the 2015-2020 Ford Explorer may experience symptoms such as inconsistent operation of lights or the inability to use power locks. The code can also affect safety systems, as many of these systems rely on data from multiple modules to function correctly. If left unaddressed, the implications can extend beyond inconvenience, leading to increased repair costs or safety risks due to malfunctioning systems. The best course of action is to diagnose the condition promptly to avoid further complications or potential vehicle breakdowns.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U068F is present:

  • The check engine light may illuminate, remaining on continuously until the issue is resolved.
  • You might notice that your vehicle's power windows and locks operate intermittently, causing frustration and inconvenience.
  • There could be a significant decrease in fuel economy, leading to increased fuel expenses as the vehicle struggles to optimize performance.
  • Other electronic features such as the radio or dashboard lights may flicker or fail to operate consistently, further impacting your driving experience.
  • In severe cases, the vehicle might experience starting issues, leaving you stranded if the BCM cannot communicate effectively.

Possible Causes

Most common causes of U068F (ordered by frequency):

  1. The most common cause of U068F, accounting for about 60% of cases, is damaged wiring or connectors between the BCM and other modules, often due to wear and tear or exposure to moisture.
  2. Another frequent culprit, about 20% of cases, is a faulty BCM itself, which may require reprogramming or replacement if it has failed.
  3. Issues with vehicle software, such as outdated firmware, can also lead to this code being triggered; ensuring software updates are performed can help prevent these problems.
  4. Less common causes include malfunctioning sensors or other control modules that are not sending or receiving data correctly, which can complicate diagnostics.
  5. In rare instances, environmental factors such as extreme temperatures can affect module communication and lead to this DTC being set.
