What is U0355?

DTC U0355 is a diagnostic trouble code that indicates a malfunction in the communication between the vehicle's control modules, specifically related to the control module for the steering angle sensor. This code is often triggered when the vehicle's onboard diagnostic system detects that the signal from the steering angle sensor control module is out of range or not responding correctly. In practical terms, this could lead to issues with the power steering system, affecting the vehicle's handling and safety. Car owners might notice an illuminated check engine light, and in some cases, the steering may feel unusually stiff or unresponsive. It's important to address this code promptly as it could indicate a deeper issue within the vehicle's electrical system or steering components. Diagnosing U0355 involves a combination of visual inspections and electronic testing, and failure to resolve the issue may result in impaired steering performance, potentially leading to unsafe driving conditions. If you're experiencing this code, it’s advisable to consult a qualified technician who can perform a thorough diagnostic check to prevent further complications.
