Causes and Fixes U0423 Code: Invalid Data Received from Instrument Panel Cluster Control Module IPC

U0423 Code: Invalid Data Received from Instrument Panel Cluster Control Module (IPC)
A U0423 code is set when one or more computer modules receive the wrong information from 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 U0423 code include a bad battery, a faulty instrument cluster, and instrument cluster wiring issues.
The CAN (Controller Area Network) is a protocol that allows computer modules to communicate with each other.
Possible Causes of a U0423 Code:
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
