Hyundai U0155 Fault Code: Instrument Cluster Communication Issue

Model: Hyundai Fault Code: U0155 Posted: 2016-03-07 08:47

I'm experiencing a Hyundai U0155 fault code issue. The error indicates a communication failure between the instrument cluster and the Engine Control Module (ECM) via the CAN bus. This means the vehicle's modules are not properly communicating with each other. I'd like to know if any modifications, added electrical devices, or recent repairs have been performed on the vehicle. Please provide details such as year, model, engine type, transmission, and color for better troubleshooting.
