NO >> Check the harness and repair the root cause.
3.CHECK HARNESS CONTINUITY (SHORT CIRCUIT)
Check the continuity between the data link connector and the ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Check the harness and repair the root cause.
4.CHECK ECM AND IPDM E/R TERMINATION CIRCUIT
1. Remove the ECM and the IPDM E/R.
2. Check the resistance between the ECM terminals.
3. Check the resistance between the IPDM E/R terminals.

Inspection result
Reproduced>>GO TO 6.
Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is
detected.

Precaution for Liquid GasketINFOID:0000000003793117
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
• Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Apply liquid gasket to the liquid gasket application surface.
Use Genuine Liquid Gasket or equivalent.
 Within 5 minutes of liquid gasket application, install the mating component.
 If liquid gasket protrudes, wipe it off immediately.
 Never retighten mounting bolts or nuts after the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.

InspectionINFOID:0000000003793121
ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and check the engine oil level is within the
range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
 Oil pans (lower and upper)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Water pump cover
 Oil cooler
 Valve timing control covers (bank 1 and bank 2)
 Mating surface between cylinder head and rocker cover
 Mating surface between front timing chain case and rear timing chain case
 Mating surface between rear timing chain case and cylinder head
 Mating surface between rear timing chain case and cylinder block
 Mating surface between rear timing chain case and oil pan (upper)
 Mating surface between cylinder block and cylinder head
 Crankshaft oil seals (front and rear)
 Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:
• Be careful not to get burn yourself, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
Inspection".
2. Remove splash guard (RH). Refer to EXT-22, "
FENDER PROTECTOR : Exploded View".

ENGINE OIL
3. Disconnect harness connector at oil pressure switch (2), and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
CAUTION:
Never drop or shock oil pressure switch.
4. Install the oil pressure gauge [SST: ST25051001 (J25695-1)] (A)
and hose [SST: ST25052000 (J25695-2)] (B).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
If difference is extreme, check engine oil passage and oil pump for engine oil leakage.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine Liquid Gasket or equivalent.
c. After warming up engine, check there is no leakage of engine oil with running engine.
DrainingINFOID:0000000003793122
WARNING:
 Be careful not to get burn yourself, as engine oil may be hot.
 Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-7, "
Inspec-
tion".
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
