Testing

Turn ignition off. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, attempt to communicate with Instrument Cluster, then Body Control Module (BCM). If scan tool communicates with either module, go to next step. If scan tool does not communicate with either module, perform PCI BUS COMMUNICATION FAILURE test.

WARNING: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal-to-pin connection.
