What is U0914?

The DTC U0914 code is a communication error indicating that the Body Control Module (BCM) is having trouble communicating with the vehicle's other control modules or the network. This issue often arises in vehicles like the 2013-2018 Ford F-Series and can lead to various functional problems. When the BCM cannot communicate effectively, it can affect systems such as the central locking, lighting, and even the engine management system. Drivers may notice symptoms like malfunctioning lights, erratic door locks, or even issues with the engine starting. The U0914 code typically appears when there is a fault in the wiring harness, a faulty BCM, or interference in the communication line. Ignoring this code could lead to further electrical issues and could even prevent the vehicle from starting. It's crucial to address this code promptly to ensure the safety and reliability of your vehicle.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0914 is present:

  • The check engine light may illuminate, indicating a potential electrical issue.
  • Lights may behave erratically, such as flickering or failing to turn on/off as expected.
  • Door locks may not function properly, leading to difficulties in locking or unlocking the vehicle.
  • The vehicle may experience starting issues, such as the engine failing to crank.
  • Fuel economy may decrease due to improper functioning of various electrical systems.

Possible Causes

Most common causes of U0914 (ordered by frequency):

  1. The most common cause is damaged wiring or connectors, which occurs in about 60% of cases. This typically happens due to wear and tear or corrosion.
  2. A faulty Body Control Module (BCM) can also cause this code to trigger, making up about 25% of cases. This often requires replacement of the BCM.
  3. Electrical interference or shorts in the communication lines can lead to U0914, which can be prevented by regular inspections of the vehicle's wiring.
  4. Less common but serious causes include water damage to the BCM or connectors, potentially leading to significant electrical issues.
  5. A rare cause could be a software glitch in one of the modules, which may require a software update or reprogramming.
