DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out by 2 persons, a driver and tester, on a level road.

NOTE
Check to make sure that the following conditions are satisfied when using this “DTC Confirmation
Procedure”.
• Altitude (barometric pressure): 2500 m, 8200 ft or less (560 mmHg, 74.4 kPa or more)

1) Clear DTC. Refer to “DTC Clearance”.
2) Start engine and drive vehicle under usual driving condition for 5 minutes or longer until engine is warmed up to
normal operating temperature.
3) Stop vehicle.
4) Run engine at idle speed for 1 minute.
5) Start vehicle and increase vehicle speed up to 120 km/h (70 mile/h).
6) Keep vehicle speed at 120 km/h (70 mile/h) for 1 minute or longer at 5th gear position or D range.
7) Decrease vehicle speed gradually.
8) Stop vehicle and turn OFF ignition switch.
9) Repeat Step 4) to 7) one time.
10) Stop vehicle.
11) Check DTC. Refer to “DTC Check”.9Oil control valve check
Check oil control valve referring to “Oil Control Valve
Inspection (For Engine with VVT) in Section 1D”.
Is resistance within specified value?Substitute a known-
good ECM and recheck.Faulty oil control valve. Step Action Yes No

DTC Troubleshooting
NOTE
Before this troubleshooting is performed, read the precautions for DTC troubleshooting referring to
“Precautions for DTC Troubleshooting”.

Step Action Yes No
1Was “Engine and Emission Control System Check”
performed?Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2Do you have SUZUKI scan tool?Go to Step 3. Go to Step 5.
3Camshaft position control check
1) With ignition switch turned OFF, connect SUZUKI scan
tool.
2) Start engine and warm up to normal operating
temperature.
3) Select menu to “Data List”.
4) Check that “VVT GAP” displayed on SUZUKI scan tool is
0 – 3°.
Is it OK?Go to Step 4. Check valve timing
referring to “Timing
Chain and Chain
Tensioner Removal and
Installation in Section
1D”. If OK, go to Step 5.
4Camshaft position control check
1) Drive vehicle under following conditions.
• Vehicle speed at 80 km/h (50 mile/h).
• Gear position at 5th or D range.
2) Check that “VVT GAP” displayed on SUZUKI scan tool is
0 – 5°.
Is it OK?Substitute a known-
good ECM and recheck.Go to Step 5.
5Oil control circuit visual inspection
1) Remove cylinder head cover referring to “Cylinder Head
Cover Removal and Installation in Section 1D”.
2) Check oil pressure leakage from oil control circuit.
Is it in good condition?Go to Step 6. Repair or replace.
6Oil control valve and oil gallery pipe check
1) Remove oil control valve referring to “Oil Control Valve
Removal and Installation (For Engine with VVT) in
Section 1D”.
2) Remove oil gallery pipe referring to “Timing Chain Cover
Removal and Installation in Section 1D”.
3) Check oil gallery pipe and oil control valve for clog or
sludge.
Are they in good condition?Go to Step 7. Clean oil control valve
and oil gallery pipe.
Replace oil control valve
if a problem is not
solved after cleaning oil
control valve and oil
gallery pipe.
7Oil control valve electrical circuit check
1) Check that oil control valve circuit is in good condition
referring to “DTC P0010: Camshaft Position Actuator
Circuit (for engine with VVT system)”.
Is circuit in good condition?Repair circuit. Go to Step 8.

DTC Troubleshooting
NOTE
If the vehicle runs under fuel deficient condition (such as a condition in which the fuel pump is unable
to draw fuel properly), DTC of misfire may possibly be detected due to fuel pressure drop even though
there is no abnormal condition existing in the Engine and Emission System.
Therefore, if the DTC still cannot be detected with “Trouble Symptom Confirmation” executed in
accordance with “Engine and Emission Control System Check” the possible cause may be due to a
running condition under insufficient fuel supply at the time of detecting DTC of misfire.

Step Action Yes No
1Was “Engine and Emission Control System Check”
performed?Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2Does fuel level meter indicate “E” level (empty)?Add fuel and recheck. Go to Step 3.
3Fuel quality check
1) Check that there is fuel of good quality in the fuel tank.
Is it OK?Go to Step 4. Clean in fuel system
circuit and change fuel.
4Ignition system check
1) Check spark plug and ignition spark of cylinder where
misfire occurs, referring to “Spark Plug Inspection in
Section 1H” and “Ignition Spark Test in Section 1H”.
Are they in good condition?Go to Step 5. Faulty ignition coil, wire
harness, spark plug or
other system parts.
5Fuel injector circuit check
1) Using sound scope, check each injector operating sound
at engine cranking or idling.
Do all injectors make operating sound?Go to Step 6. Check coupler
connection and wire
harness of injector not
making operating sound
and injector itself. If OK,
substitute a known-
good ECM and recheck.
6Fuel pressure check
1) Check fuel pressure referring to “Fuel Pressure Check”.
Is check result satisfactory?Go to Step 7. Repair or replace fuel
system.
7Fuel injector check
1) Check fuel injector(s) referring to “Fuel Injector
Inspection in Section 1G”.
Is check result satisfactory?Go to Step 8. Replace defective
injector.
8Ignition timing check
1) Check ignition timing referring to “Ignition Timing
Inspection in Section 1H”.
Is check result satisfactory?Go to Step 9. Check related sensors.
9EGR system check
1) Check EGR system referring to “EGR System Inspection
(If Equipped) in Section 1B”.
Is check result satisfactory?Go to Step 10. Repair or replace EGR
system.
10Exhaust system check
1) Check exhaust system for exhaust gas clogged.
Is it OK?Go to Step 11. Repair clogged of
exhaust system.
