The Nissan diagnostic trouble code (DTC) indicates a Turbocharger Boost Communication Line Malfunction . It belongs to the network communication class of codes ("U" codes). This fault occurs when the Engine Control Module (ECM) loses communication with the electronic turbocharger actuator. This specific code is highly common in Nissan diesel vehicles, particularly the Nissan Navara, NP300, Pathfinder, and NV350 equipped with the YD25 or similar turbo-diesel engines.
