BASIC INSPECTION
When the malfunction is not confirmed in the DTC check, troubleshooting should be carried out in all the
possible circuits considered as causes of the problem. In many cases, by carrying out the basic engine check
shown in the following flowchart, the location causing the problem can be found quickly and efficiently. There-
fore, using this check is essential in the engine troubleshooting.
1 CHECK BATTERY VOLTAGE
NOTICE:
Carry out this check with the engine stopped and ignition switch OFF.

3 PERFORM ENGINE RPM ACCELERATION
HINT:
If exhaust gas contain excessive black smoke, perform the following steps.
(a) Accelerate the engine speed up to the maximum RPM with no load 20 times.
(b) Check the volume of the black smoke in the exhaust gas.
Result:
ResultProceed to
Black smoke is fadedOK
Black smoke remains in the exhaust gasNG
HINT:
Deposited soot in the exhaust system is a source of the excessive black smoke.
NG Go to step 4
OK
END
4 CHECK AIR INTAKE SYSTEM AND EXHAUST SYSTEM
(a) Remove the air cleaner filter.
(b) Inspect the EGR valve operation.
(1) Start the engine and warm it up.
(2) Check that a clicking sound is heard from the EGR valve when the vacuum hose is disconnected
from EGR valve with the engine in an idle.
(c) Inspect the intake shutter (throttle valve) operation.
(1) Start the engine.
(2) Check if the intake shutter fully opens when accelerating the engine speed.
HINT:
Under quick accelerating of the engine speed, the EGR valve is fully closed and the intake shutter is fully
opened. If the systems are normal, the volume of the black smoke will result in decrease.
NG Go to step 5
OK

REPLACEMENT
NOTICE:
If an incorrect injector compensation code was registered with the ECM, it may rattle the engine as-
sembly or the engine idling may become rough. In addition, it may become a cause of engine failure
or shorten the life of the engine.
HINT:
SIn order to optimize the injector’s fuel injection characteristic, the ECM compensates the injection dura-
tion by each cylinder. The ECM stores and uses compensating data in the form of a 30−digit−alphanu-
meric value that is imprinted on the head portion of each injector as the injector compensation code.
SIf you installed a new injector, its own injector compensation code is needed to register with the ECM.
Also, if you replaced the ECM, the compensation codes of all the injectors are needed to register be-
cause the new ECM does not have the codes until they are registered.
SOnce the ECM is replaced, DTC P1601 will be present when turning the ignition switch to ON. This
is to inform you that the injector compensation codes are required to register with the ECM. In order
to clear the DTC, register the compensation codes first, then turn the ignition switch to OFF and wait
for 30 seconds or longer.
