Power Circuits (Ignition Off)

Turn ignition off. Check for battery voltage between ECM power terminals and ground. See ECM POWER TERMINAL IDENTIFICATION  table. If battery voltage does not exist, check fuse or fusible link. Fuses are located under instrument panel. On some models, an auxiliary fuse panel is located in engine compartment. Fusible links are in engine compartment. If fuse and fusible link are okay, check for an open in wire between fuse/fusible link and ECM. See WIRING DIAGRAMS article.
