Ground Circuits
- Using a DVOM, check for continuity to ground at the following PCM connector terminals. See Figure
. Resistance should be approximately zero ohms. If resistance is not approximately zero ohms, repair circuit open to ground.
- Terminal numbers not available from manufacturer at time of publication.
- Touch negative lead of voltmeter to a good ground. With vehicle running, backprobe positive lead of voltmeter to each ground terminal. Voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion or loose connection on ground lead.
