The U0353 code indicates a communication failure between your vehicle's Engine Control Module and the steering angle sensor. This can lead to issues with stability control and traction systems, making your vehicle harder to handle, especially in adverse conditions. Ignoring it may result in further damage and safety risks.
What are the most common causes of U0353 and how much does it cost to fix?
Common causes include a faulty steering angle sensor, damaged wiring, or software issues. Repair costs can range from $100 for wiring repairs to $500 for sensor replacement, depending on the specific problem.
Can I drive my car with U0353 or should I stop immediately?
You can drive your vehicle short distances, but it is not advisable to ignore the code. The loss of communication with the steering angle sensor can lead to compromised vehicle handling and safety systems, so addressing it as soon as possible is crucial.
How can I diagnose U0353 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform a full vehicle scan to retrieve the U0353 code and any related codes. The app will show you real-time data from the steering angle sensor, allowing you to identify if it’s sending the correct signals to the ECM for further investigation.
What vehicles are most commonly affected by U0353?
Vehicles commonly affected by U0353 include the 2015-2020 Chevrolet Silverado, GMC Sierra, and other GM models with advanced electronic stability features. It's important to check for any recalls related to the steering systems on these vehicles.
How can I prevent U0353 from happening again?
Regular maintenance of your vehicle's electronics, including periodic inspections of wiring and connectors, can help prevent U0353. Additionally, keeping your software updated through professional services is essential to ensure all systems communicate properly.
What is U0353?
The U0353 diagnostic trouble code indicates a loss of communication between the vehicle's Engine Control Module (ECM) and the steering angle sensor. This sensor is crucial for various vehicle stability systems, including electronic stability control (ESC) and traction control. When the ECM can't communicate with the steering angle sensor, it may trigger warning lights on the dashboard, such as the check engine light or stability control warning. This issue can lead to a range of performance problems, including erratic steering behavior, increased difficulty in handling, and potential safety concerns if the stability control systems cannot function properly. In practical terms, if you're experiencing U0353, it is essential to address this promptly to ensure your vehicle's handling and safety features are operational. Ignoring this code could lead to further complications, including steering column malfunctions, which can be costly to repair. Drivers of vehicles such as the 2015-2020 Chevrolet Silverado or GMC Sierra, among others, may encounter this issue frequently due to the integration of advanced driver-assistance systems (ADAS) that rely heavily on accurate steering data.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0353 is present:
- Check engine light stays on constantly, indicating a persistent issue that requires immediate attention.
- Steering feels unresponsive or erratic, with the steering wheel sometimes not returning to the center position after a turn.
- Increased difficulty in handling the vehicle, especially during tight maneuvers or when driving on slippery surfaces.
- Stability control warning light illuminates, suggesting that the vehicle's stability systems may not operate effectively.
- Unusual noises coming from the steering column area, which could indicate mechanical issues related to the steering angle sensor.
Possible Causes
Most common causes of U0353 (ordered by frequency):
- The most common cause of U0353 is a faulty steering angle sensor, which accounts for approximately 60% of cases. This can happen due to wear and tear or electrical issues.
- Another prevalent cause is damaged wiring or connections between the ECM and the steering angle sensor, which can result in intermittent communication failures.
- A third cause can be software malfunctions or calibration issues within the vehicle's control modules, making it essential to update or reprogram the software as necessary.
- Less common but serious causes include ECM failure, which requires replacement and can be a costly repair.
- A rare but possible cause could be a complete steering column failure, which affects multiple systems and may lead to a significant safety risk.
