CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to the ªLOCKº
position.
2) Connect CONSULT-II to Data Link
Connector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 mph)
for at least one minute.
1) Stop vehicle with engine run-
ning and touch ªSTARTº on
CONSULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
lThe screen shows the detected
malfunction and how many times
the ignition switch has been
turned since the malfunction.
MALFUNCTION REPAIR
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Make the necessary repairs following
the diagnostic procedures.
After repairing the malfunctions, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp for deactivation
after driving vehicle over 30 km/h (19
mph) for at least one minute.

IOn models equipped with air conditioner, checks should
be carried out while the air conditioner is ªOFFº.
IWhen checking idle speed on models equipped with CVT,
ignition timing and mixture ratio, checks should be carried
out while shift lever is in ªPº or ªNº position.
IWhen measuring ªCOº percentage, insert probe more
than 40 cm (15.7 in) into tail pipe.
ITurn off headlamps, heater blower, rear window defogger.
IOn vehicles equipped with daytime running light systems,
set lighting switch to the 1st position to light only small
lamps.
IKeep front wheels pointed straight ahead.
IIf engine stops immediately after starting or idle condition
is unstable, perform the following to initialize IACV-AAC
valve:
a)Stop engine and wait 9 seconds.
b)Turn ignition ªONº and wait 1 second.
c)Turn ignition ªOFFº and wait 9 seconds.
IMake the check after the cooling fan has stopped.

Without CONSULT-IINCEC0541S02021. Start engine and warm it up to normal operating temperature.
2. Check that all items listed under the topic ªPre-Conditioningº
(previously mentioned) are in good order.
3. Turn ignition switch ªOFFº and wait at least 9 seconds.
4. Start the engine and allow it to idle for at least 28 seconds.
5. Disconnect throttle position sensor harness connector (brown),
then re-connect it within 5 seconds. (CVT models only)
6. Wait 20 seconds.
7. Make sure that the idle speed is within specifications. If not, the
result will be incomplete. In this case, find the cause of the
problem by referring to the NOTE below.
8. Rev up the engine two or three times. Make sure that idle
speed and ignition timing are within specifications.

NOTE:
IIf idle air volume learning cannot be performed
successfully, proceed as follows:
a)Check the throttle valve is fully closed.
b)Check that downstream of throttle valve is free from air
leakage.
c)Adjust closed throttle position switch and reset memory.
(Refer to Basic Inspection, EC-SR-84.)
d)When the above three items check out OK, engine com-
ponent parts and their installation condition are question-
able. Check and eliminate the cause of the problem.
e) If any of the following conditions occur after the engine has
started, eliminate the cause of the problem and perform ªIdle
air volume learningº all over again:
IEngine stalls.
IErroneous idle.

REAR WINDOW DEFOGGER TIMER
The rear window defogger and door mirror defogger system are controlled by the TCU. With the ignition
switch in the ON or START position, power is supplied

to the rear window defogger relay

to TCU terminal
1

through 10A fuses [No.5, located in the fuse block (J/B)].
Ground is supplied to terminal

14of the rear window defogger switch through body groundsM6,M26and
M28.
When the rear window defogger switch is ON, ground is supplied

through terminal
16of the rear window defogger switch

to TCU terminal
3.
Terminal

13of the TCU then supplies ground to the rear window defogger relay.
With power and ground supplied, the rear window defogger relay is energized to operate rear window
defogger and door mirror defogger for about 15 minutes.
For further information, refer to REAR WINDOW DEFOGGER DOOR and MIRROR DEFOGGER (EL-207).
IGNITION KEY WARNING BUZZER
Ground is supplied to TCU terminal
6through front driver’s side door switch when switch is in OPEN
position from body ground.
With the key in the ignition switch in the ACC or OFF position, and locking the driver’s door from the inside,
the warning buzzer will sound.
LIGHT WARNING BUZZER
Power is supplied at all times

through 30A fusible link (letterg, located in the fuse and fusible link box) (LHD models)

through 15A fuse (No.66, located in the fuse and fusible link box) (RHD models)

to lighting switch terminal
11.
Power is supplied at all times

through 7.5A fuse [No.40, located in the fuse block (J/B)]

to warning buzzer terminal
1.
With the ignition switch in the ON or START position, power is supplied

through 7.5A fuse [No.12, located in the fuse block (J/B)]

to BCM terminal
29.
Ground is supplied to TCU terminal

6through front driver’s side door switch when switch is in OPEN
position from body ground.
With the ignition switch in the ACC or OFF position, the driver’s door OPEN, and the lighting switch in the
1st or 2nd position, the warning buzzer will sound.
INTERIOR LAMP TIMER
Power is supplied at all times

through 10A fuse [No.5, located in the fuse block (J/B)]

to interior lamp terminal
1
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No.26, located in the fuse block (J/B)]

to TCU terminal
1.
When the driver’s door is unlocked, a door is opened and then closed, or the ignition is turned from“ON”
to“Acc”or“LOCK”, ground is supplied to the interior lamp terminal

2for approximately 30 seconds.
The 30 seconds timer will be cancelled if the ignition switch is turned to“ON”, or the driver’s door is locked.

* : If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. ECM does not detect the
switch is ON even if the switch does turn ON. Therefore, the ECM does not supply power to light up the lamp.
* : If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. ECM does not detect the switch
is ON even if the switch does turn ON. Therefore, the ECM does not control ground to light up the lamp.
