What vehicles are most commonly affected by U019A?

The U019A code is commonly found in 2015 to 2020 Ford Focus models, as well as other vehicles equipped with electric power steering systems. It is essential to check for any recalls or technical service bulletins related to your specific make and model.

How can I prevent U019A from happening again?

To prevent U019A from recurring, regularly inspect the power steering system for wear and tear, keep connections clean and free from corrosion, and consider using the GeekOBD APP to perform periodic diagnostics on your vehicle to catch potential issues early.

What is U019A?

The U019A diagnostic trouble code indicates a communication failure between the electric power steering control module and other control modules within the vehicle. This issue suggests that the steering system is unable to communicate effectively with the vehicle's onboard computer system, which can lead to a range of problems, including a loss of power steering assistance. When this code appears, it can result in a stiff steering wheel and difficulty in maneuverability, especially at low speeds. The electric power steering system is crucial for modern vehicles, as it enhances fuel efficiency and driving comfort. If left unresolved, this code could lead to more significant steering issues, affecting the safety and handling of your vehicle. Vehicle owners may notice the steering warning light illuminate on the dashboard, and they may also experience erratic steering behavior. It’s important to address U019A promptly to ensure safe driving conditions and maintain the integrity of the steering system.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U019A is present:

  • The steering warning light illuminates on the dashboard, indicating a potential issue with the power steering system.
  • Steering feels stiff or unresponsive, making it difficult to turn the vehicle, particularly at lower speeds.
  • Unusual noises may be heard from the steering column or power steering unit, indicating possible mechanical failure.
  • Loss of power steering assistance, causing the driver to exert more effort when steering.
  • Intermittent steering control, where the steering may work normally at times and fail at others.

Possible Causes

Most common causes of U019A (ordered by frequency):

  1. The most common cause of U019A is a faulty power steering control module, with an estimated likelihood of about 60%. This module is responsible for processing signals and may fail due to electrical issues or internal faults.
  2. Another frequent cause is damaged wiring or loose connections in the power steering system, which can disrupt communication. This issue could account for approximately 20% of cases and is often the result of wear and tear over time.
  3. Corrosion or dirt in the connectors can prevent proper communication, which is why regular maintenance and inspection are essential, making up about 10% of occurrences.
  4. A less common but serious cause includes a complete failure of the electric power steering assembly, which requires immediate replacement.
  5. In rare cases, software glitches within the vehicle's computer systems can lead to this code, often needing a software update or reprogramming.
