Common Questions

What does U0395 mean and how does it affect my car?

The U0395 code indicates that your vehicle's onboard computer has lost communication with the steering angle sensor module. This can affect your car's handling, stability control, and overall safety. Without proper communication, features like traction control may not work correctly, leading to a higher risk of losing control, especially during adverse driving conditions.

What are the most common causes of U0395 and how much does it cost to fix?

Common causes of U0395 include a faulty steering angle sensor, damaged wiring in the steering column, or improper calibration after repairs. Repair costs can range from $150 for sensor replacement to $100 for minor wiring fixes. Software updates may cost around $50.

Can I drive my car with U0395 or should I stop immediately?

While you may technically be able to drive your vehicle with the U0395 code active, it is not recommended. The loss of steering assistance and stability control can pose significant safety risks. It's best to have the vehicle inspected and repaired as soon as possible.

How can I diagnose U0395 myself using GeekOBD APP?

To diagnose U0395 using the GeekOBD APP, connect the device to your vehicle's OBD2 port. Use the app to read the diagnostic trouble codes and check for freeze frame data. This will help you understand when the error occurred and under what conditions, allowing for a more targeted diagnostic approach.

What vehicles are most commonly affected by U0395?

The U0395 code is commonly found in vehicles like the 2015-2018 Ford F-150, 2016-2019 Chevrolet Silverado, and several models from Toyota and Honda during the same years. Always check for any recalls or technical service bulletins related to the steering systems for these vehicles.

How can I prevent U0395 from happening again?

To prevent U0395 from recurring, ensure regular maintenance of your vehicle's steering and electrical systems. Keep an eye on any signs of wear, such as unusual noises or warning lights, and address issues promptly. Regular inspections can also help catch wiring and connector problems before they lead to communication failures.

What is U0395?

The diagnostic trouble code (DTC) U0395 indicates that the vehicle's onboard computer has lost communication with the steering angle sensor module. This code is prevalent in various modern vehicles, especially models like the 2015-2018 Ford F-150. The steering angle sensor plays a crucial role in the vehicle's stability control systems and advanced driver-assistance systems (ADAS). When this sensor fails or loses communication, it can lead to several issues, including the inability to effectively control the vehicle's steering and stability features, which can compromise safety. Real-world implications of this code include the activation of warning lights on the dashboard, such as the ABS or traction control lights, and could lead to erratic steering behavior. Drivers may also notice issues with the vehicle’s handling, particularly when cornering or during sudden maneuvers. If left unaddressed, this communication failure can result in more significant problems with the vehicle's electronic systems, potentially leading to costly repairs. Therefore, understanding and addressing the U0395 code promptly is essential for maintaining vehicle safety and performance.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0395 is present:

  • The Check Engine light or other warning lights stay illuminated on the dashboard, indicating a potential issue with the steering system.
  • Drivers may experience a loss of steering assistance, making it difficult to maneuver the vehicle, particularly at lower speeds.
  • There may be erratic behavior of the vehicle's stability control systems, such as unexpected activation of traction control or ABS, which can feel unsettling during driving.
  • Increased wear on tires due to improper alignment caused by steering angle miscommunication, leading to poor fuel efficiency.
  • Drivers might notice difficulty in returning the steering wheel to center, affecting overall driving experience.

Possible Causes

Most common causes of U0395 (ordered by frequency):

  1. The most common cause of U0395 is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor might fail due to wear and tear or exposure to moisture.
  2. Another potential cause is damaged wiring or connectors in the steering column, contributing to nearly 25% of issues. Corrosion or physical damage can prevent proper signal transmission.
  3. Improper calibration after repairs or replacements can also trigger this code, often seen in vehicles that have undergone steering or suspension work.
  4. Less commonly, a malfunctioning powertrain control module (PCM) could misinterpret signals from the sensor, leading to erroneous readings.
  5. Rarely, software glitches in the vehicle’s electronic control systems can cause communication failures, sometimes resolved with a software update.
