Instrument Panel Cluster (IPC) Diagnostic System Check: Notes
WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Unless scan tool directions indicate otherwise, always exit all scan tool test before cycling ignition switch from OFF to ON position. Follow all scan tool manufacturer's instructions. If scan tool instructions are not followed, vehicle may set DTCs (may be false codes), vehicle systems may malfunction or scan tool may malfunction.
NOTE:
Use this check as the starting point for any IPC complaint. IPC is a very reliable component, and is not likely the cause of malfunction. Most malfunctions are caused by faulty wiring, connectors or components.
