2.PRECONDITIONING-2
Is “Diagnosis Procedure” of DTC P0524 finished?
.
.
 
3.PERFORM DTC CONFIRMATION PROCEDURE
  1. Start engine and warm it up to normal operating temperature.
  2. Maintain the following conditions for about 10 consecutive seconds.
    Selector leverP or N position
    Engine coolant temperature70°C (158°F) or more
    Engine speed1,000 rpm or more
    noteWith engine speed set around 4,000 rpm, the phenomenon can be reproduced more easily.
  3. Check 1st trip DTC.
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.
-1To check malfunction symptom before repair: Refer to Intermittent IncidentIntermittent Incident.
-2Confirmation after repair: INSPECTION END
 
4.CHECK ENGINE OIL LEVEL
Check engine oil pressure. Refer to Inspection.
Is the inspection result normal?
.
Refer to DTC Diagnosis Procedure.
 
5.CHECK ENGINE OIL PRESSURE
With M.U.T.-III SE
  1. Turn ignition switch ON.
  2. Select “DATA MONITOR” mode of “ENGINE” using M.U.T.-III SE.
  3. Start the engine and check that “EOP SENSOR” changes, according to engine speeds.
