at end of article. displayed after ignition is turned off for 12 minutes and oil level is low.
- Ensure oil level is at proper level. Disconnect engine oil level switch connector. Engine oil switch is located on oil pan, under oil filter. Leave ignition off for 12 minutes. Turn ignition on and observe Electronic Vehicle Information Center (EVIC) display for one minute.
- If EVIC briefly displays CHECK ENGINE OIL LEVEL, go to step 4). If EVIC does not display CHECK ENGINE OIL LEVEL, disconnect engine node 12-pin connector. See Fig 1 . Check connector condition, and clean or repair connector as necessary.
- Turn ignition off. Using an external ohmmeter, check resistance of Brown/Gray wire between engine oil level switch connector and terminal No. 10 of engine node 12-pin connector. If resistance is more than 5 ohms, repair open Brown/Gray wire. Perform VERIFICATION PROCEDURE VER-1. If resistance is less than 5 ohms, replace engine node. Perform VERIFICATION PROCEDURE VER-1.
- If EVIC briefly displayed CHECK ENGINE OIL LEVEL in step 2), put DRB-II in ohmmeter mode. Turn ignition off. Check resistance on center terminal of engine oil level switch. If resistance is more than 5 ohms, replace engine oil level switch. Perform VERIFICATION PROCEDURE VER-1. If resistance is less than 5 ohms, drain engine oil.
- Check resistance on center terminal of engine oil level switch. If resistance is less than 1000 ohms, replace engine oil level switch. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 1000 ohms, low oil warning system is functioning correctly. Perform VERIFICATION PROCEDURE VER-1.
