Code U0155 Nissan Description

The U0155 diagnostic trouble code for Nissan vehicles indicates that there is a communication failure between the Engine Control Module (ECM) and the Instrument Panel Cluster Control Module (IPCCM). The Instrument Panel Cluster Control Module is responsible for controlling various functions on the instrument panel, such as the speedometer, tachometer, fuel gauge, and warning lights. When communication is lost between the ECM and IPCCM, it can lead to a range of issues affecting the vehicle's performance and functionality.
