Common Questions

What does U0135 mean and how does it affect my car?

The U0135 code indicates a communication issue between your vehicle's control module and the steering angle sensor. This can lead to loss of traction control and stability functions, potentially making your car harder to handle, especially during slippery conditions.

What are the most common causes of U0135 and how much does it cost to fix?

The most common causes include damaged wiring (60% likelihood), faulty steering angle sensors, and software glitches. Repair costs can range widely, from $150 to $600 depending on whether it's a wiring repair or sensor replacement.

Can I drive my car with U0135 or should I stop immediately?

While you may be able to drive your car, it's not recommended as the loss of stability control can lead to dangerous driving conditions. It's best to have the vehicle inspected as soon as possible.

How can I diagnose U0135 myself using GeekOBD APP?

Using the GeekOBD APP, you can scan for diagnostic trouble codes and access freeze frame data. Look for codes related to the steering system, and check the live data to see if the steering angle sensor is providing readings.

What vehicles are most commonly affected by U0135?

Vehicles like the 2014-2018 Ford F-150 and 2013-2017 Chrysler 300 are frequently affected by U0135. It's important to check manufacturer recalls or Technical Service Bulletins (TSBs) related to this code.

How can I prevent U0135 from happening again?

Regular maintenance, including checking the wiring and connectors in the steering system, can help prevent U0135. Keep your vehicle's software up to date and address any electrical issues promptly.

What is U0135?

The diagnostic trouble code U0135 indicates that there is a communication issue between the vehicle's control module and the steering angle sensor module. This typically affects vehicles equipped with electronic stability control (ESC) and other advanced driver assistance systems (ADAS). When U0135 is triggered, it usually means that the control module is not receiving data from the steering angle sensor, which is crucial for the vehicle’s handling and stability during operation. Commonly found in models like the 2014-2018 Ford F-150 and 2013-2017 Chrysler 300, this code can lead to a variety of issues such as loss of traction control, stability control, and even steering assistance. The vehicle may exhibit symptoms like a constant warning light on the dashboard, erratic steering behavior, and an overall decrease in driving confidence. Addressing this code typically involves diagnosing wiring issues, checking for software updates, or replacing faulty components. Ignoring this code can result in further complications, including the potential for reduced handling capabilities and increased risk of accidents. Therefore, understanding and resolving the U0135 code promptly is crucial for maintaining the vehicle’s safety and performance.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0135 is present:

  • The check engine light or stability control warning light stays illuminated on the dashboard, indicating potential issues with vehicle stability systems.
  • You may notice erratic steering behavior, such as the steering wheel being unresponsive or feeling disconnected, which can make driving hazardous.
  • Fuel economy may decrease by approximately 10-15% as the vehicle’s stability systems may be working harder to compensate for the lack of data from the steering angle sensor.
  • The vehicle may engage traction control or stability systems intermittently, leading to unexpected braking or power loss during acceleration.
  • You might experience difficulty in steering at low speeds, especially when making tight turns or parking.

Possible Causes

Most common causes of U0135 (ordered by frequency):

  1. The most common cause of U0135 is damaged wiring or connectors in the steering column, with a likelihood of around 60%. This is often due to wear and tear or accidents that affect the steering system.
  2. Another cause could be a faulty steering angle sensor, which may require replacement. This issue often arises due to moisture ingress or electrical failure.
  3. Software glitches in the vehicle’s control module can also trigger U0135. Regular updates from the manufacturer can mitigate this problem; therefore, keeping your vehicle's software up to date is essential.
  4. Less common but serious causes include a malfunctioning electronic control unit (ECU) that may require reprogramming or replacement, which is critical for vehicle safety.
  5. A rare cause is an issue with the vehicle’s main computer, which can lead to widespread communication failures across multiple systems.
