Ground Circuits
WARNING: This page is about a different variant/trim than selected.
- Using an ohmmeter, check for continuity to ground on ECM/PCM/VCM ground terminals. Resistance should be zero ohms. If not, repair open to ground.
- Using a DVOM, touch negative lead of voltmeter to a good ground. Touch positive lead of voltmeter to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If voltmeter reading is greater than one volt, check for open, corrosion or loose connection on ground circuit.
