What is U0CE6?

DTC U0CE6 is a diagnostic trouble code that indicates a communication error between the vehicle's body control module (BCM) and other control modules. This problem can arise in various makes and models, but it's notably prevalent in 2015 to 2018 Honda Accord vehicles. When you see this code, it suggests that there is an issue with the data flow, which can lead to various electrical problems. The body control module is responsible for managing functions like power windows, door locks, and interior lighting. If there's a communication failure, these systems may malfunction, leading to inconvenience and potential safety issues. For instance, you might find that the headlights flicker or the central locking system is unresponsive. Ignoring this code could lead to more severe electrical problems down the line, so it's essential to address it promptly. Understanding the implications of U0CE6 not only helps maintain the functionality of your vehicle's systems but also prevents costly repairs in the future.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0CE6 is present:

  • Check engine light stays on constantly, indicating an underlying issue that needs to be resolved.
  • Power windows or door locks may malfunction, leading to inconvenience when trying to operate them.
  • Interior lighting may flicker or remain off, affecting visibility and safety inside the vehicle.
  • Fuel economy may decrease due to the vehicle's systems not functioning optimally.
  • Warning lights for other systems may appear intermittently, signaling broader electrical issues.

Possible Causes

Most common causes of U0CE6 (ordered by frequency):

  1. The most common cause of U0CE6 is a faulty body control module, with a likelihood of about 40%. This can occur due to age, wear, or manufacturing defects.
  2. Wiring issues, such as damaged or corroded connectors, are the second most common cause at around 30%. Inspecting the wiring harness can reveal issues that need fixing.
  3. Software glitches in the BCM can also lead to this code, accounting for 20% of cases. Updating or resetting the module may solve the problem.
  4. Less commonly, electrical shorts due to aftermarket modifications can result in U0CE6. These should be addressed carefully to avoid further damage.
  5. A rare cause might be a failing ignition switch, which can disrupt communication within the vehicle's electrical system, although this occurs in only about 10% of cases.
