3. DTC CHECK (Check Mode):
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has more sens-
ing ability to detect malfunctions. Furthermore, the same diag-
nostic items which are detected in the normal mode can also be
detected in the check mode.
(a) Procedure for Check Mode using the hand±held tester.
(1) Check the initial conditions.

Battery positive voltage 11V or more.

Throttle valve fully closed.

Transmission in the ºNº position.

A/C switched OFF.
(2) Turn the ignition switch OFF.
(3) Connect the hand±held tester to the DLC3.
(4) Turn the ignition switch ON and switch the hand±
held tester main switch ON.
(5) Switch the hand±held tester from the normal mode
to the check mode. The CHK ENG blinks in 0.13 sec
intervals as shown in the illustration.
NOTICE:
If the hand±held tester switches the ECM from the normal
mode to the check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during the check
mode, the DTC and freeze frame data will be erased.
(6) Start the engine. (The CHK ENG goes off after the
engine start.)
(7) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(8) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the
DTCs and freeze frame data, etc.
HINT:
Be sure not to turn the ignition switch OFF, because the diagno-
sis system is changed from the check mode to the normal mode
and will result in all of the DTCs and freeze frame data being
erased.
(9) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clearing the DTCs using the hand±held tester:
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating the hand±held tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)

(c) Clearing the DTCs not using the hand±held tester:
(1) Disconnect the battery terminal or remove the EFI
and ETCS fuses from the engine room R/B for more
than 60 seconds.

5. CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's ECM in the check mode, the 1 trip detection logic is possible instead of the 2 trip
detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect intermittent
problems.
(a) Clear the DTCs (See step 2).
(b) Set the check mode (See step 3).

8. READ INJECTOR COMPENSATION CODE
HINT:
This operation is useful when confirming the compensation
code of each injector or when DTC P1601 is present.
(a) Connect the hand±held tester to the DLC 3.
(b) Turn the ignition switch ON.
(c) Turn the main switch of the hand±held tester ON.
NOTICE:
Do not start the engine in this operation.

(k) Input the 30±digit±alphanumeric code with the hand±
held tester to register the compensation code to the ECM.
NOTICE:
Be careful not to register a wrong compensation code to
the ECM. The compensation code which stored in the ECM
must be consistent with the compensation code of the in-
jector assembly. If a wrong code was set to the ECM, rough
idling or engine rattling may result. In addition, it may be a
cause of the engine failure or short±life.
(l) After inputting, press the ºENTERº button.
(m) Press the ºENTERº button again.
(n) Confirm the injection compensation code which is dis-
played on the hand±held tester.
HINT:
The code shown in the illustration is an example.
NOTICE:

Make sure the correct compensation code is entered
on the hand±held tester before pressing YES button.

If a wrong compensation code was entered on the
hand±held tester, select the ºNOº button to correct
the error (Back to step (g)).
(o) Press the ºYESº button to set the code to the ECM.
(p) Wait until the next screen comes up.

BASIC INSPECTION
When the malfunction is not confirmed in the DTC check, troubleshooting shou\
ld 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 flow chart, the location causing the problem can be found quickly and efficiently.
Therefore, using this check is essential in the engine troubleshooting.
1CHECK BATTERY VOLTAGE
NOTICE:
Carry out this check with the engine stopped and ignition switch OFF.

(a) Visually check that the air filter is not excessively dirty or oily.
NOTICE:
If necessary, clean the filter with compressed air. First blow
from the inside thoroughly, then blow from the outside of
the filter.
