What is U0365?

DTC U0365 is a diagnostic trouble code that indicates a communication issue within the vehicle's network, specifically related to the control module. This code is often encountered in vehicles like the 2015-2018 Honda Civic, but can also appear in other makes and models. It signifies that the module is having trouble sending or receiving information from the vehicle's onboard computer system. In practical terms, this could lead to various performance issues, including malfunctioning systems that rely on data exchange, such as the anti-lock brakes, traction control, or even the check engine light illuminating. Drivers may experience symptoms such as erratic behavior in electronic components, failure of safety features, or a general drop in vehicle performance. Ignoring this code can lead to further complications, as unresolved communication issues may cause other modules to fail or behave unpredictably. Therefore, it's crucial to address U0365 promptly to maintain your vehicle's performance and safety.

System: U - Network (Communication, CAN Bus)

Symptoms
