What vehicles are most commonly affected by U035E?

The U035E code is frequently encountered in 2013-2018 Ford Fusion vehicles, among others. Always check for any specific recalls or Technical Service Bulletins (TSBs) related to your model.

How can I prevent U035E from happening again?

Regular maintenance checks on your vehicle's wiring and sensor systems, along with timely software updates, can help prevent the recurrence of the U035E code.

What is U035E?

The U035E diagnostic trouble code indicates a communication issue with the vehicle's control modules, specifically the communication with the steering angle sensor module. This code typically arises when the vehicle's onboard diagnostic system detects that it cannot establish a proper communication link with the steering angle sensor, which is vital for advanced driver-assistance systems (ADAS) such as electronic stability control and lane-keeping assist. In practical terms, this can lead to issues with steering responsiveness and may even disable certain safety features, making it a serious concern for drivers. If left unaddressed, the problem could escalate, leading to more severe steering system failures or safety risks while driving. Common symptoms include the check engine light illuminating and possible erratic steering behavior. It's crucial to diagnose and rectify the underlying issues quickly to ensure the vehicle operates safely and efficiently.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U035E is present:

  • The check engine light remains illuminated, indicating a potential issue that needs immediate attention.
  • Drivers may experience inconsistent steering responses, making it difficult to control the vehicle accurately.
  • Fuel economy may decrease by 10-15% due to the vehicle's systems trying to compensate for the communication failure.
  • Advanced safety features such as lane-keeping assist may become non-functional, increasing the risk during driving.
  • Occasional steering wheel vibrations while driving could indicate underlying issues with the steering angle sensor.

Possible Causes

Most common causes of U035E (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, accounting for about 60% of cases. This sensor may fail due to wear or damage over time.
  2. Corroded or damaged wiring and connectors can also lead to communication issues, with a likelihood of around 25%. Inspecting the wiring harness for visible damage is critical.
  3. Software glitches in the vehicle's control module may account for about 10% of cases. Keeping the vehicle's software updated can help prevent this.
  4. Less common issues include failed control modules, which can be expensive to replace and diagnose.
  5. In rare instances, extreme weather conditions can impact sensor performance, leading to temporary communication loss.
