What vehicles are most commonly affected by U0519?

The U0519 code is commonly found in the 2015-2019 Ford F-150 and other Ford models with electronic power steering. Always check for any recalls or technical service bulletins related to your vehicle.

How can I prevent U0519 from happening again?

To prevent U0519, ensure regular maintenance of your vehicle's electrical systems, keep connections clean and free from corrosion, and consider software updates during routine service.

What is U0519?

The U0519 diagnostic trouble code indicates that there is a communication error between the vehicle's control modules, specifically relating to the power steering control module. This code typically arises when the power steering control module fails to communicate effectively with the vehicle's central computer, leading to various operational issues. In practical terms, this means that your vehicle may experience difficulty in steering, especially at low speeds, or the steering might feel unusually heavy. This code is often seen in models like the 2015-2019 Ford F-150, where advanced steering systems are integrated into the vehicle's overall electrical architecture. If left unresolved, the communication failure could lead to more severe steering issues, impacting your safety on the road. Drivers might also notice the 'Check Steering' warning light illuminating on the dashboard, and in some cases, the vehicle may enter a 'limp mode' to protect itself from further damage. Addressing the U0519 code promptly is crucial to ensure your vehicle operates safely and efficiently.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0519 is present:

  • Check engine light or steering warning light stays on constantly, indicating a problem with the power steering system.
  • Steering feels heavy or unresponsive, especially during low-speed maneuvers, making it difficult to turn the wheel.
  • Increased effort required to steer the vehicle, which may lead to driver fatigue and loss of control in critical situations.
  • Unusual noises from the steering column, such as grinding or whining, indicating potential mechanical issues within the power steering system.
  • Intermittent loss of power steering assist, where the system occasionally functions correctly but fails at other times.

Possible Causes

Most common causes of U0519 (ordered by frequency):

  1. The most common cause is a faulty power steering control module, which could account for approximately 60% of cases. This module may fail due to electrical faults or internal malfunctions.
  2. Another common cause is damaged wiring or corroded connectors between the power steering control module and the vehicle's main computer, affecting communication integrity.
  3. A third potential cause is software glitches, where the module may require a firmware update or reprogramming to restore proper function.
  4. Less commonly, a failing battery or alternator may result in insufficient voltage to power the electronics, causing intermittent communication issues.
  5. In rare cases, a malfunctioning electronic control unit (ECU) may lead to miscommunication between modules, requiring comprehensive diagnostics to identify.
