HIGH OIL CONSUMPTION/LEAKAGE (VIN Y) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	INSPECT ENGINE OIL AND RELATED PARTS Inspect the following: Proper oil level gauge Engine oil viscosity Engine oil level Are all the items normal?	Yes	Go to the next step.
1		No	Repair or replace the malfunctioning location 1, then repeat from Step 1.
2	INSPECT FOR ENGINE OIL LEAKAGE Inspect for engine oil leakage from the outside of the engine. Is there engine oil leakage?	Yes	Repair or replace the malfunctioning location and perform the repair completion verification 1.
2		No	Go to the next step.
3	DETERMINE IF MALFUNCTION CAUSE IS DUE TO PCV VALVE OR INTERNAL ENGINE MALFUNCTION Inspect the PCV valve. (Refer to POSITIVE CRANKCASE VENTILATION (PCV) VALVE INSPECTION (VIN Y) .) Is the PCV valve normal?	Yes	Go to the next step.
3		No	Replace the PCV valve and perform the repair completion verification 1. (Refer to POSITIVE CRANKCASE VENTILATION (PCV) VALVE REMOVAL/INSTALLATION (VIN Y) .)
4	RECORD TRAVELED DISTANCE Record the vehicle ARfs traveled distance. NOTE: By recording the traveled distance and having the customer bring the vehicle in for servicing after traveling 2, 000 km {1, 243 mile}, it is possible to determine whether the cause is an engine malfunction or the engine oil consumption is fast depending on the customer's driving conditions.	-	For first-time customers: Explain that the customer should travel 2, 000 km {1, 243 mile} and then bring the vehicle back in for servicing. Perform the repair completion verification 1. For customers bringing their vehicle back in for servicing after traveling 2, 000 km {1, 243 mile}: Go to the next step.
5	INSPECT ENGINE OIL LEVEL Inspect the engine oil level. (Refer to ENGINE OIL LEVEL INSPECTION (VIN Y) .) Is the engine oil level normal?	Yes	Explain to the customer that the vehicle is normal and perform the repair completion verification 1.
5		No	If the engine oil level is above MIN: Explain to the customer that the vehicle is normal and perform the repair completion verification 1. If the engine oil level is below MIN: Inspect for internal engine wear, damage. Cylinder Piston ring Intake/exhaust valve Cylinder head gasket If there is any malfunction: Repair or replace the malfunctioning location and perform the repair completion verification 1.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Has the malfunction symptom been eliminated?	Yes	Complete the symptom troubleshooting. (Explain contents of repair to customer)
Repair completion verification 1		No	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, go to the next step.
Repair completion verification 2	VERIFY IF MALFUNCTION IS CAUSED BY NOT PERFORMING PCM REPROGRAMMING Verify repair information and verify that there is a new calibration in the PCM. Is there a new calibration in the PCM?	Yes	Perform the PCM reprogramming and verify if the malfunction symptom was corrected. If the malfunction recurs, replace the PCM. (Refer to PCM REMOVAL/INSTALLATION (VIN Y) .)
Repair completion verification 2		No	Replace the PCM. (Refer to PCM REMOVAL/INSTALLATION (VIN Y) .)
