  2. Check IPC power and ground circuits for opens or shorts. See appropriate POWER DISTRIBUTION or GROUND DISTRIBUTION article in WIRING DIAGRAMS. Repair as necessary and attempt to establish communications with Instrument Panel Cluster (IPC). If scan tool communicates with IPC, go to next step. If scan tool does not communicate with IPC, go to SCAN TOOL DOES NOT COMMUNICATE WITH IPC  under SYSTEM TESTS.
