DTC U0155: Lost Communication With Instrument Panel Cluster (IPC) Control Module: Action
WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
CARRY OUT a self-test of the IPC module. If the diagnostic scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to DIAGNOSE the network communication concern. If IPC module DTCs are present, REFER to INSTRUMENT CLUSTER AND PANEL ILLUMINATION to DIAGNOSE the IPC system fault.
