Ground Circuits
WARNING: This page is about a different car, the 1995 Isuzu Rodeo. However, it is still accessible from the selected car via links, so may be relevant.
Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.
