October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Ground Circuits
- Using an ohmmeter, check for continuity to ground on ECU terminals A23, A24, A26, and B2. Resistance should be zero ohms. If not, repair open to ground.
- Using a DVOM, connect negative lead to a good ground. Backprobe 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 lead.
