How can I diagnose U0471 myself using GeekOBD APP?
To diagnose U0471 with the GeekOBD APP, connect the app to your vehicle’s OBD2 port, retrieve the trouble codes, and analyze the freeze frame data. This will help you understand the context of the fault, enabling you to take informed action.
What vehicles are most commonly affected by U0471?
DTC U0471 frequently appears in 2014-2019 Chevrolet Silverados and GMC Sierras, among other GM vehicles. Keeping an eye on any recalls or technical service bulletins (TSBs) related to these models can help.
How can I prevent U0471 from happening again?
To prevent U0471 from reoccurring, regularly inspect your vehicle's wiring and connectors for damage, keep software updated, and ensure that any repairs are performed correctly.
What is U0471?
DTC U0471 is a diagnostic trouble code indicating a communication issue within the vehicle’s network, specifically related to the 'Lost Communication with Steering Angle Sensor Module'. This code is commonly found in General Motors (GM) vehicles, particularly models like the Chevrolet Silverado (2014-2019) and GMC Sierra (2014-2019). When this code appears, it means that the Engine Control Module (ECM) is unable to establish communication with the steering angle sensor. This sensor is crucial for various vehicle systems, including stability control and advanced driver-assistance systems (ADAS). If the system cannot receive data from the steering angle sensor, it may lead to improper functioning of these systems, potentially compromising vehicle safety. Owners may experience issues such as the ABS light illuminating, the stability control light flashing, or the traction control system failing to engage. Ignoring this code could lead to safety concerns during driving, particularly in adverse weather conditions, as the vehicle may not respond as expected during cornering or emergency maneuvers. Therefore, addressing DTC U0471 promptly is essential to ensure the vehicle operates safely and efficiently.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0471 is present:
- Check engine light stays on constantly, indicating a persistent issue that requires attention.
- Stability control light illuminates, which may suggest the system is not functioning correctly in critical driving situations.
- Traction control system warning appears, leading to potential traction issues during acceleration or braking.
- Unusual steering response, such as the steering feeling heavy or unresponsive, particularly in turns.
- Increased difficulty in maneuvering the vehicle, which can be particularly noticeable at lower speeds.
Possible Causes
Most common causes of U0471 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, with a likelihood of around 60%. If this sensor malfunctions, it can disrupt communication with the ECM.
- Another frequent cause is damaged wiring or connectors between the steering angle sensor and the ECM, which may occur due to wear and tear or improper installation.
- Corrosion in the electrical connectors can lead to poor connections, contributing to communication issues. Regular inspections can help prevent this.
- Less commonly, issues with the ECM itself may result in this code. If other codes are present, further diagnosis is needed to determine if the ECM is failing.
- A rare cause could be a software glitch within the vehicle’s computer systems. Updating the software may resolve this issue.
