How to fix U0155 Code: Lost Communication with Instrument Panel Control (IPC) Module
A U0155 code is set when one or more computer modules have lost communication with the Instrument Panel Control (IPC) module.
Symptoms include instrument cluster performance problems and no indicator lights in the instrument panel cluster.
Common causes of the U0155 code include a dead battery, a damaged instrument cluster, and instrument cluster circuit issues.
The CAN (Controller Area Network) is a protocol that allows computer modules to communicate with each other.

Possible Causes of the U0155 Code:
Issues with Power Source (Alternator or Battery)
Blown Fuse (Check Computer Module ECM/PCM/ECU/IPC Fuses)
Instrument Cluster Wiring Issues (Bad Ground / Bad Connections / Open or Short)
Faulty Instrument Panel Control (IPC) Module
