Using the GeekOBD APP, you can perform a scan to retrieve diagnostic codes, view live data from the modules, and check for any freeze frame data that might indicate when the issue occurred.

What vehicles are most commonly affected by U014E?

Vehicles like the 2015-2018 Ford F-150, 2016-2019 Chevrolet Silverado, and various models from Chrysler and Dodge frequently experience the U014E code, often due to common wiring issues or module faults.

How can I prevent U014E from happening again?

Regular vehicle maintenance, including inspections of the wiring and connections, can help prevent U014E. Make sure to address any electrical issues as soon as they arise.

What is U014E?

DTC U014E is a diagnostic trouble code that indicates a communication issue between the vehicle's control modules, specifically the Powertrain Control Module (PCM) and another module, often the Body Control Module (BCM). This code typically arises when the PCM cannot receive or send messages to the BCM, leading to potential malfunctions in critical vehicle systems such as engine performance, transmission control, and safety features. For instance, in popular models like the 2015-2018 Ford F-150, this can manifest as erratic shifts, stalling, or even a no-start condition. The root cause of this issue may include damaged wiring, poor connections, or module failures. Ignoring this code can lead to more severe issues, including reduced vehicle safety and performance, making it essential for owners to address it promptly. If your vehicle displays the U014E code, it's vital to have it diagnosed and repaired to prevent further complications.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U014E is present:

  • The check engine light illuminates and stays on, indicating a persistent issue that requires attention.
  • The engine may hesitate or stall during acceleration, leading to unsafe driving conditions.
  • Drivers may notice a significant decrease in fuel economy, potentially by 10-15%, impacting overall vehicle efficiency.
  • The vehicle may experience erratic transmission behavior, such as harsh shifting or slipping.
  • In some cases, owners may find that power windows or locks are non-functional due to the communication failure.

Possible Causes

Most common causes of U014E (ordered by frequency):

  1. The most common cause is damaged wiring or connectors, which accounts for approximately 60% of cases. Corroded or frayed wires can disrupt communication between modules.
  2. Another frequent cause is a malfunctioning Body Control Module (BCM), which may fail to send or receive signals correctly due to internal faults.
  3. Poorly performing sensors, such as those related to the engine or transmission, can also lead to U014E. Regularly inspecting and replacing worn-out sensors can help prevent this.
  4. Less common but serious is a complete module failure, which may require replacement of the PCM or BCM, often the most costly repair.
  5. A rare cause could be software issues within the modules, which may necessitate a software update or reprogramming to resolve.
