DTC U0155: Lost Communication With Instrument Panel Cluster (IPC) Control Module: Action
WARNING: This page is about a different car, the 2012 Ford Pickup. 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 scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK - F150 to DIAGNOSE the network communication concern. If IPC module DTCs are present, REFER to INSTRUMENT CLUSTER ILLUMINATION AND PANEL ILLUMINATION - F150 to DIAGNOSE the IPC system fault.
