U0155 Chevrolet Code - Lost Communication With Instrument Panel Cluster Control Module

Quick Answer

The U0155 code for Chevrolet vehicles indicates that there is a communication problem between the vehicle's Engine Control Module (ECM) and the Instrument Panel Cluster Control Module (IPCC). Common causes include Faulty wiring or connectors between the ECM and IPCC, A malfunctioning IPCC module, Water damage or corrosion affecting the communication network. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0155 Chevrolet Description

The U0155 code for Chevrolet vehicles indicates that there is a communication problem between the vehicle's Engine Control Module (ECM) and the Instrument Panel Cluster Control Module (IPCC). This means that the ECM is not receiving information or data from the IPCC, which is responsible for controlling various functions on the instrument panel, such as the speedometer, fuel gauge, and warning lights.
