What is U0274?

DTC U0274 is a diagnostic trouble code that indicates a communication issue between the vehicle's control modules, specifically related to the steering column control module. This code signifies that the steering column control module is unable to communicate with the vehicle's other control units, such as the engine or transmission control modules. This can lead to various operational issues, impacting steering performance and safety features. When this code is triggered, it can often result in symptoms like the loss of power steering assistance, warning lights on the dashboard, or even a complete failure of the steering system in severe cases. For vehicle owners, this means you may experience difficulty maneuvering your car, especially at low speeds. The U0274 code commonly appears in models such as the 2015-2018 Honda Civic, 2017-2019 Ford Fusion, and various other makes and models that utilize electronic steering systems. Ignoring this code can lead to more significant problems down the line, including complete steering failure, which could pose a serious safety risk. Therefore, it's crucial to address the U0274 code promptly by diagnosing and repairing the underlying issues that triggered it.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0274 is present:

  • Check engine light illuminates continuously, indicating a malfunction in the steering system.
  • Loss of power steering assistance, making it harder to turn the steering wheel, especially at low speeds.
  • Intermittent warning messages on the dashboard, indicating steering system errors.
  • Unusual noises from the steering column when turning, suggesting mechanical issues.
  • Increased fuel consumption due to inefficient vehicle operation caused by the communication issue.

Possible Causes

Most common causes of U0274 (ordered by frequency):

  1. The most common cause is a faulty steering column control module, occurring in approximately 60% of cases. This module can fail due to wear and tear or electrical issues.
  2. A damaged wiring harness or poor connections account for about 25% of U0274 occurrences. Corrosion or physical damage can disrupt communication between modules.
  3. A software glitch in the vehicle's electronic control units can cause communication failures. Regular updates can help prevent this issue.
  4. Less common but serious causes include physical damage to the steering system or control module, which can require significant repairs.
  5. Rarely, a complete failure of the vehicle's CAN bus system can lead to U0274, requiring extensive diagnostics and repairs.
