Test 10A - Faulty Low Oil Message

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagram, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
NOTE: Faulty low oil message will set only after ignition is off for 12 minutes and oil level is low.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Ensure oil is at recommended level. Allow vehicle to sit for 12 minutes. Turn ignition switch to ON position. Observe EVIC messages for one minute. If EVIC message CHK ENGINE OIL LEVEL does not appear briefly, go to step 5). If CHK ENGINE OIL LEVEL message appears briefly, go to next step.
  2. Using DRB, read oil level switch status. If DRB displays OIL LEVEL : CLOSED, replace engine node. If DRB does not display OIL LEVEL : CLOSED, go to next step.
  3. Disconnect engine oil level switch connector, located in oil pan. Check, clean and repair connections as needed. Connect jumper wire between oil level switch connector terminal (Brown/Gray wire) and ground. If DRB displays OIL LEVEL : CLOSED, replace oil level switch. If DRB does not display OIL LEVEL : CLOSED, go to next step.
  4. Disconnect jumper wire. Disconnect engine node connector. Check, clean and repair connections as needed. Using an external ohmmeter, measure resistance of Brown/Gray wire between engine node connector terminal No. 10 and engine oil level switch connector. If resistance is less than 5 ohms, replace engine node. If resistance is more than 5 ohms, repair open in Brown/Gray wire between oil level switch connector and engine node connector.
  5. If EVIC message CHK ENGINE OIL LEVEL appears briefly in step 1), drain engine oil. Turn ignition switch to ON position. Observe EVIC messages for one minute. If EVIC message CHK ENGINE OIL LEVEL appears briefly, system is operating properly at this time. If CHK ENGINE OIL LEVEL does not appear, go to next step.
  6. Disconnect oil level switch connector. Using DRB, read oil level switch status. If DRB displays OIL LEVEL : OPEN, replace oil level switch. If DRB does not display OIL LEVEL : OPEN, go to next step.
  7. Disconnect engine node connector. Put DRB in ohmmeter mode. Measure resistance at engine node connector terminal No. 10 (Brown/Gray wire). If resistance is less than 5 ohms, repair Brown/Gray wire for short to ground between engine node connector and oil level switch. If resistance is more than 5 ohms, replace engine node.
