HOW TO ERASE DTC (WITH GST)=NLAT0020S041. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªEURO-OBD SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-28. (The engine
warm-up step can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC section ªGeneric Scan Tool (GST)º.
HOW TO ERASE DTC (NO TOOLS)NLAT0020S051. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-28. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
Refer to EC section ªHOW TO SWITCH DIAGNOSTIC TEST MODESº.

Malfunction Indicator (MI)NLAT00211. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
+If the malfunction indicator lamp does not light up, refer to EL
section (ªWarning Lamps/System Descriptionº, ªWARNING
LAMPS AND CHIMEº).
(Or see MI & Data Link Connectors in EC section.)
2. When the engine is started, the malfunction indicator lamp
should go off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to EC section (ªON BOARD DIAGNOSTIC SYS-
TEM DESCRIPTIONº).

gent.
+Do not disassemble IAC valve-AAC valve.
+Even a slight leak in the air intake system can cause seri-
ous problems.
+Do not shock or jar the camshaft position sensor and
crankshaft position sensor.
+Before replacing ECM, perform refer to ªECM Terminals
and Reference Valueº inspection and make sure ECM
functions properly, EC-133.

+After performing each TROUBLE DIAGNOSIS, perform
ªDTC Confirmation Procedureº or ªOverall Function
Checkº.
The DTC should not be displayed in the ªDTC Confirma-
tion Procedureº if the repair is completed. The ªOverall
Function Checkº should be a good result if the repair is
completed.

+When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
+Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the
ECM's transistor. Use a ground other than ECM terminals,
such as the ground.

Idle Air Volume LearningNLEC0562DESCRIPTIONNLEC0562S01ªIdle Air Volume Learningº is an operation to learn the idle air vol-
ume that keeps each engine within the specific range. It must be
performed under any of the following conditions:
+Each time IACV-AAC valve, throttle body or ECM is replaced.
+Idle speed or ignition timing is out of specification.
PRE-CONDITIONINGNLEC0562S02Before performing ªIdle Air Volume Learningº, make sure that all of
the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are
missed for even a moment.
+Battery voltage: More than 12.9V (At idle)
+Engine coolant temperature: 70 - 99ÉC (158 - 210ÉF)
+PNP switch: ON
+Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, set lighting
switch to the 1st position to light only small lamps.
+Cooling fan motor: Not operating
+Steering wheel: Neutral (Straight-ahead position)
+Vehicle speed: Stopped
+Transmission: Warmed-up
M/T models, drive vehicle for 10 minutes.
OPERATION PROCEDURENLEC0562S03With CONSULT-IINLEC0562S03011. Start engine and warm it up to normal operating temperature.
2. Check that all items listed under the topic ªPRE-CONDITION-
INGº (previously mentioned) are in good order.
3. Turn ignition switch ªOFFº and wait at least 9 seconds.
4. Start the engine and let it idle for at least 28 seconds.
5. Select ªIDLE AIR VOL LEARNº in ªWORK SUPPORTº mode.
6. Touch ªSTARTº and wait 20 seconds.
7. Make sure that ªCMPLTº is displayed on CONSULT-II screen.
If ªINCMPº is displayed, ªIdle Air Volume Learningº will not be
carried out successfully. In this case, find the cause of the
problem by referring to the NOTE below.

IntroductionNLEC0029MODELS WITH EURO-OBD SYSTEMNLEC0029S01The ECM has an on board diagnostic system which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
Diagnostic Trouble Code (DTC) Mode 3 of ISO 15031-5
Freeze Frame data Mode 2 of ISO 15031-5
System Readiness Test (SRT) code Mode 1 of ISO 15031-5
1st Trip Diagnostic Trouble Code (1st Trip DTC) Mode 7 of ISO 15031-5
1st Trip Freeze Frame data
Test values and Test limits Mode 6 of ISO 15031-5

*2: 1st trip DTCs for self-diagnoses concerning SRT items cannot be shown on the GST display.
*3: In diagnostic test mode II (Self-diagnostic results), DTC is displayed on MI. DTC uses a set of four digit numbers.
The malfunction indicator (MI) on the instrument panel lights up when the same malfunction is detected in two
consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-123.)

Two Trip Detection LogicNLEC0030MODELS WITH EURO-OBD SYSTEMNLEC0030S01When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in
the ECM memory. The MI will not light up at this stage <1st trip>.
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored
in the ECM memory, and the MI lights up. The MI lights up at the same time when the DTC is stored <2nd
trip>.
