Specification data are reference values.
On Board Diagnosis LogicEBS01KFM
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer toCO-7, "
Changing Engine
Coolant". Also, replace the engine oil. Refer toLU-6, "Changing Engine Oil".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer toMA-16, "
Engine Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS01KFN
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
lNever remove a radiator cap and/or a reservoir tank cap when the engine is hot. Serious burns
could be caused by high pressure fluid escaping from the radiator and the reservoir tank.
lWrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.

GLOW CONTROL SYSTEMPFP:25230
DescriptionEBS01KLM
SYSTEM DESCRIPTION
*: The output signal is sent from the ECM through CAN communication line.
When engine coolant temperature is more than approximately 80°C(176°F), the glow relay turns off.
When engine coolant temperature is lower than approximately 80°C(176°F):
lIgnition switch ON
After ignition switch has turned to ON, the glow relay turns ON for a certain period of time in relation to
engine coolant temperature, allowing current to flow through glow plug.
lCranking
The glow relay turns ON, allowing current to flow through glow plug.
lSta rti ng
After engine has started, current continues to flow through glow plug (after-glow mode) for a certain period
in relation to engine coolant temperature.
The glow indicator lamp turns ON for a certain period of time in relation to engine coolant temperature at the
time glow relay is turned ON.
COMPONENT DESCRIPTION
Glow Plug
The glow plug is provided with a ceramic heating element to obtain a
high-temperature resistance. It glows in response to a signal sent
from the ECM, allowing current to flow through the glow plug via the
glow relay.

Precautions For Liquid GasketEBS01E5N
REMOVAL OF LIQUID GASKET
lAfter removing the mounting bolts and nuts, separate the mating
surface using the seal cutter [SST] and remove the old liquid
gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
lTap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.
lIn areas where seal cutter [SST] is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
lRemove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach the liquid gasket tube to the tube presser [SST].
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
lIf there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
lAs for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.
lWithin five minutes of liquid gasket application, install the mat-
ing component.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten mounting bolts or nuts after the installation.
lAfter 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.

PRECAUTIONS
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
DIESEL ENGINE
Diesel fuel of at least 50 cetane.
If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper-
ature conditions.
lAbove –7°C(20°F) ... Summer type diesel fuel.
lBelow –7°C(20°F) ... Winter type diesel fuel.
CAUTION:
lDo not use home heating oil, gasoline or other alternate fuels in your diesel engine. The use of
those can cause engine damage.
lDo not use summer fuel at temperatures below –7°C(20°F). The cold temperatures will cause wax
to form in the fuel. As a result, it may prevent the engine from running smoothly.
lDo not add gasoline or other alternate fuels to diesel fuel.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS001GN
lBefore connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Turbocharger (If Equipped)EAS001GO
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
lAlways use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
lAvoid accelerating engine to a high rpm immediately after start-
ing.
lIf engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS001GP
HOSE REMOVAL AND INSTALLATION
lTo prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
UNDER SEATING AREAS
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or
pinching.
Heat Sensitive
The customer's concern may occur during hot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60°C(140°F).If incident occurs
while heating the unit, either replace or properly insulate the compo-
nent.
Freezing
The customer may indicate the incident goes away after the car
warms up (winter time). The cause could be related to water freezing
somewhere in the wiring/electrical system.
There are two methods to check for this. The first is to arrange for
the owner to leave his car overnight. Make sure it will get cold
enough to demonstrate his complaint. Leave the car parked outside
overnight. In the morning, do a quick and thorough diagnosis of
those electrical components which could be affected.
The second method is to put the suspect component into a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the reoccurrence of the incident. If it occurs, repair or
replace the component.
Water Intrusion
The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the incident could be caused by water intru-
sion on an electrical part. This can be simulated by soaking the car
or running it through a car wash.
Do not spray water directly on any electrical components.
Electrical Load
The incident may be electrical load sensitive. Perform diagnosis with
all accessories (including A/C, rear window defogger, radio, fog
lamps) turned on.
