What is U0B67?

DTC U0B67 is a network communication-related trouble code indicating a problem with a vehicle's communication network, specifically involving the vehicle's body control module (BCM) and other control units. This code typically arises when there are issues in data transmission between modules, which can lead to various malfunctions in vehicle features such as lighting, power windows, and other electronic components. For instance, in models like the 2016-2020 Ford Explorer or 2017-2021 Chevrolet Malibu, this may manifest as unresponsive electronic features or issues with keyless entry. The underlying causes can range from wiring problems to module failures. If left unresolved, it can lead to significant inconveniences and even safety concerns, especially if critical systems begin to fail. Therefore, understanding the implications of a U0B67 code is crucial for maintaining your vehicle's electronic systems and overall functionality.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0B67 is present:

  • The check engine light may remain illuminated continuously, indicating a persistent issue with the vehicle's diagnostic system.
  • Drivers may notice that electronic features such as power windows or door locks are unresponsive, creating inconvenience or safety issues.
  • Fuel economy may decrease, as the vehicle may be compensating for malfunctioning systems, leading to irregular engine performance.
  • The vehicle may experience intermittent failures of various electronic components, such as headlights flickering or dashboard lights malfunctioning.
  • In some cases, the vehicle may not start or exhibit a slow crank, which could be related to communication failures within the control modules.

Possible Causes

Most common causes of U0B67 (ordered by frequency):

  1. The most common cause of the U0B67 code, accounting for about 40% of cases, is damaged wiring or loose connections in the vehicle’s communication network. Inspecting the wiring harness and ensuring all connections are secure can often resolve the issue.
  2. Another frequent cause, approximately 30% of the time, is a faulty body control module (BCM). If the BCM is malfunctioning, it may not properly communicate with other modules, leading to various symptoms. Testing the BCM with a multimeter can help determine if it needs replacement.
  3. A third cause, which occurs in around 20% of instances, is software issues or outdated firmware in the vehicle’s modules. Keeping the vehicle's software updated through dealership services can prevent these types of issues.
  4. Less common but serious issues, such as internal faults within communication modules, may occur and typically require more in-depth diagnostics and professional repair.
  5. Rarely, environmental factors like water intrusion or extreme temperatures can affect internal connections or modules, leading to a U0B67 code.
