DIAGNOSES
Preliminary Check(PriortoRoad Testing)
AIT FLUID CHECK
Fluid leakage check

1. Clean areasuspected ofleaking, -for example, mating
surface ofconverter housingandtransmission case.
2. Start engine, applyfootbrake, placeselector leverin"0"
position andwait afew minutes.
3. Stop engine.
4. Check forfresh leakage.

Road Testing

Perform roadtests using "Symptom" chart.Refertopage

AT-20.

"P"
POSITION

1. Place selector leverin"P" position andstart engine. Stop
engine andrepeat theprocedure inall positions, including
neutral position.
2. Stop vehicle onaslight upgrade andplace selector leverin
"P" position. Releaseparkingbraketomake surevehicle
remains locked.

"R"
POSITION

1. Manually moveselector leverfrom"P"to"R", andnote
shift quality.
2. Drive vehicle inreverse longenough todetect slippage or
other abnormalities.

"N"
POSITION

1. Manually moveselector leverfrom"R"and"0"to"N" and
note shift quality.
2. Release parkingbrakewithselector leverin"N" position.
Lightly depress accelerator pedaltomake surevehicle
does notmove. (When vehicle isnew orsoon afterclutches
have been replaced, vehiclemaymove slightly. Thisisnot
a problem.)

since itinvolves theriskoflowering strength.
When heating isunavoidable, donot heat
such parts attemperatures above550°C (1,

Heating temperature shouldbeverified with
a thermometer. (Acrayon-type andother

• When straightening bodypanels, usecaution
in pulling anyHSS panel. Because itis very
strong, thismay cause deformation inadja-

increase thenumber ofmeasuring points,
and carefully pulltheHSS panel.
Special
consideration forHSS must begiven tothe following points:

• Incutting HSSpanel, avoidgascutting if
possible. Instead,useanairsaw orahand

the number ofsingle digits. Forexample, themalfunction indicatorlampblinks 4times forabout 2.5
seconds (0.6secx4 times) andthen itblinks threetimes forabout 1second (0.3secx3 times). This
indicates theDTC "43" andrefers tothe malfunction ofthe throttle position sensor.
In this way, allthe detected malfunctions areclassified bytheir diagnostic troublecodenumbers. The
DTC "55" refers tono malfunction. (SeeDIAGNOSTIC TROUBLECODECHART, refertoEC-62.)

HOW TOERASE DIAGNOSTIC TESTMODE II(Self-diagnostic results)

The diagnostic troublecodecanbeerased fromthebackup memory inthe ECM when thediagnostic
test mode ischanged fromDiagnostic TestMode IIto Diagnostic TestMode
I.
(Refer to"HOW TO
SWITCH DIAGNOSTIC TESTMODES" onprevious page.)

• Ifthe battery terminal isdisconnected, thediagnostic troublecodewillbelost from thebackup
memory within24hours.
• Becareful nottoerase thestored memory before
startin~
troublediagnoses.

• If
the MIL blinks or"NATS MALFUNCTION" isdisplayed on
"SELF-OIAG RESULTS"screen,perform self-diagnostic
results modewithCONSULT usingNATS program card
(NATS-E940). RefertoEL section.
• Confirm noself-diagnostic resultsofNATS isdisplayed
before touching "ERASE" in"SELF-DIAG RESULTS"mode
with CONSULT.
• When replacing ECM,initialisation ofNATS V2.0system and
registration ofall NATS V2.0ignition key10smust becar-
ried outwith CONSULT usingNATS program card(NATS-
E940).
Therefore, besure toreceive allkeys from vehicle owner.
Regarding theprocedures ofNATS initialisation andNATS
ignition key10registration, refertoCONSULT operation
manual, NATS V2.0.

PRECAUTIONS
Engine Oils(ConI' d)

• Wash withsoap andwater toensure alloil isremoved (skin
cleansers andnailbrushes willhelp). Preparations contain-
ing lanolin replace thenatural skinoilswhich havebeen
removed.
• Donot use gasoline, kerosine, dieselfuel,gasoil,thinners
or solvents forcleaning skin.

• If
skin disorders develop,obtainmedical advicewithout
delay.
• Where practicable, degreasecomponents priortohandling.
• Where thereisarisk ofeye contact, eyeprotection should
be worn, forexample, chemicalgogglesorface shields; in
addition aneye wash facility should beprovided.

ENVIRONMENTAL PROTECTIONPRECAUTIONS

Burning usedengine oilinsmall space heaters orboilers can
be recommended onlyforunits ofapproved design.Theheat-
ing system mustmeettherequirements ofHM Inspectorate of
Pollution forsmall burners ofless than 0.4MW. Ifin doubt check
with theappropriate localauthority and/ormanufacturer ofthe
approved appliance.
Dispose ofused oiland used oilfilters through authorized
waste disposal contractors tolicensed wastedisposal sites,or
to the waste oilreclamation trade.Ifin doubt, contact thelocal
authority foradvice ondisposal facilities.
It is illegal topour used oilontothe ground, downsewers or
drains, orinto water courses.
The regulations concerningthepollution ofthe environment
will vary between regions.

Precautions forFuel
GASOLINE ENGINE:

For Europe

Unleaded gasolineofat least 95octane (RON)
CAUTION: Do not use leaded gasoline. Usingleaded gasoline willdamage
the catalytic converter.

Except Europe

Unleaded gasolineofat least 91octane (RON)

DIESEL ENGINE*:

Diesel fuelofat least 50cetane
If two types ofdiesel fuelareavailable, usesummer or
winter fuelproperly according tothe following temperature
conditions.
• Above -rc(20°F) Summer typediesel fuel.
• Below
-rc
(20°F) Wintertypediesel fuel.
CAUTION:
• Donot use home heating oil,gasoline, orother alternate
fuels inyour diesel engine. Theuseofthose cancause
engine damage.
• Donot use summer fuelattemperature below_7°C(20°F).
The cold temperatures willcause waxtoform inthe fuel. As
a result, itmay prevent theengine fromrunning smoothly.
• Donot add gasoline orother alternate fuelstodiesel fuel.
