Power Circuits (Ignition On)

WARNING: This page is about a different car, the 2001 Subaru Outback, 2001 Subaru Legacy, 2001 Subaru Impreza, and 2001 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition on. Check for battery voltage between ECM power terminals and ground. For ECM power terminal identification, see appropriate pin voltage chart in PIN VOLTAGE CHARTS article. If battery voltage does not exist, check fuse. If fuse is okay, check for an open in wire or a defective ignition switch. See WIRING DIAGRAMS article.
