What is U0E44?

DTC U0E44 is a diagnostic trouble code that pertains to issues within the vehicle's communication network, particularly the Controller Area Network (CAN) bus. This code indicates that the vehicle's modules are not able to communicate effectively. When this happens, you may experience multiple problems that can affect the performance of your vehicle. For instance, this code is commonly found in 2015-2019 Ford vehicles, indicating potential faults in modules such as the powertrain control module (PCM) or body control module (BCM). The underlying causes can range from a simple wiring issue to a failing module that needs replacement. Ignoring this code can lead to various operational problems, including system failures. It’s crucial to address this code promptly to avoid further complications. Regular diagnostics and checking the vehicle's communication system can help prevent the manifestation of this code, ensuring that all components function harmoniously. If you find yourself with this code, it’s wise to take it to a qualified technician who can conduct a thorough investigation into the communication systems of your vehicle.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0E44 is present:

  • Check engine light stays on constantly, indicating a persistent issue that requires immediate attention.
  • Dashboard warning lights may illuminate, including ABS, traction control, or stability control indicators, leading to potential safety concerns.
  • Engine performance may suffer, resulting in rough idling or stalling, which can be frustrating and potentially dangerous.
  • Loss of functionality in non-critical systems like power windows or door locks, indicating a broader electrical issue.
  • Increased fuel consumption, which may be noticeable, as the vehicle's engine management system struggles to optimize performance.

Possible Causes

Most common causes of U0E44 (ordered by frequency):

  1. Faulty wiring or connectors in the CAN bus system - The most common cause (approximately 40% likelihood). Look for frayed wires or poor connections.
  2. Malfunctioning control modules, like the PCM or BCM - This can happen over time due to wear, contributing to a 30% chance of triggering this code.
  3. Electrical interference from aftermarket accessories or poor grounding - Be cautious if you've added new components, as this has a 20% likelihood of being the cause.
  4. Software issues within the vehicle's modules, which can sometimes be resolved with a firmware update - Less common but can account for around 5% of cases.
  5. Rarely, a complete failure of the vehicle's main computer could result in this code, although this is a low-probability scenario.
