ECM Ground Circuits
WARNING: This page is about a different car, the 1995 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
For ECM location, see COMPONENT LOCATIONS under INTRODUCTION. Measure resistance between engine (ground) and specified terminals of ECM connector. See ECM GROUND CIRCUITS table. If resistance is more than one ohm, repair ground circuit. If resistance is one ohm or less, ground circuit is okay (ECM may be faulty).
