A. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions. The water pump draws the coolant from the radiator. The coolant then
circulates through water jackets in the engine block, the intake manifold, and the cylinder head.
When the coolant reaches the operating temperature of the thermostat, the thermostat opens.
The coolant then goes back to the radiator where it cools. The heat from automatic transmission
is also cooled down through the radiator by circulating the oil through the oil pump. ECU controls
the electric cooling fans with three cooling fan relays to improve the engine torque and air
conditioning performance.
For detailed information, refer to Chapter "Air Conditioning System".

4. DIAGNOSTIC INFORMATION AND PROCEDURE
1) Oil Leak Diagnosis
Most fluid oil leaks are easily located and repaired by visually finding the leak and replacing or
repairing the necessary parts. On some occasions a fluid leak may be difficult to locate or repair.
The following procedures may help you in locating and repairing most leaks.
Finding the Leak ▶
Identify the fluid. Determine whether it is engine oil, automatic transmission fluid, power
steering fluid, etc.
Identify where the fluid is leaking from. -
-
After running the vehicle at normal operating temperature, park the vehicle over a large
sheet of paper.
Wait a few minutes.
You should be able to find the approximate location of the leak by the drippings on the
paper. ·
·
·
Visually check around the suspected component.
Check around all the gasket mating surfaces for leaks. A mirror is useful for finding leaks
in areas that are hard to reach.
If the leak still cannot be found, it may be necessary to clean the suspected area with a
degreaser, steam or spray solvent. -
-
Clean the area well.
Dry the area.
Operate the vehicle for several miles at normal operating temperature and varying
speeds.
After operating the vehicle, visually check the suspected component.
If you still cannot locate the leak, try using the powder or black light and dye method. ·
·
·
·
·
Clean the suspected area.
Apply an aerosol-type powder (such as foot powder) to the suspected area.
Operate the vehicle under normal operating conditoins.
Visually inspect the suspected component. You should be able to trace the leak path over
the white powder surface to the source. -

5) Jump Starting Procedure
Position the vehicle with the charged battery so that the jumper cables will reach from the
charged battery to the battery that requires charging.
Turn off the ignition, all the lights, and all the electrical loads in both vehicles.
Leave the hazard flasher on if jump starting where there may be other traffic and any other
lights needed for the work area.
Apply the parking brake firmly in both vehicles. 1.
2.
3.
4.
Shift an automatic transmission to PARK. 5.
Clamp one end of the first jumper cable to the positive terminal on the booster battery. Make
sure it does not touch any other metal parts.
Clamp the other end of the same cable to the positive terminal on the discharged battery.
Never connect the other end to the negative terminal of the discharged battery. 6.
7.
Clamp one end of the second cable to the negative terminal of the booster battery.
Make the final connection to a solid engine ground, such as the engine lift bracket at least 450
millimeters (18 inches) from the discharged battery.
Start the engine of the vehicle with the good battery.
Run the engine at a moderate speed for several minutes.
Then start the engine of the vehicle with the discharged battery.
Remove the jumper cables by reversing the above sequence exactly, removing the negative
cable from the vehicle with the discharged battery first.
While removing each clamp, take care that it does not touch any other metal while the other
end remains attached. 8.

12.In order to avoid damaging the vehicle make sure the cables are not on or near pulleys, fans,
or other parts that will move when the engine starts.
In order to avoid injury, do not use cables that have loose or missing insulation.

ABS Warning Light
This warning light comes on
when the ignition switch is
turned to "ON" position and
should go out if the system is
normal.
The vehicle with ABS performs
self-diagnosis. During this
diagnosis, brake pedal
vibration and noise may be
apparent when the driving
motors discharges the
hydraulic pressure from the
internal hydraulic device.4WD IndicatorLow Fuel Level
Warnig Light
This warning light
comes on when the
fuel will soon be
exhausted. The time
it takes turn on,
however, varies
according to the
gradient of the
vehicle.
4WD HIGH Indicator
The lamp blinks momentarily during
the change of driving mode.
4WD LOW Indicator
The lamp blinks momentarily during
the change of driving mode.
4WD CHECK Warning Light
This indicates that there is
something wrong in the transfer
case system. (check the system) -

Auto Cruise Control
Indicator
Operating the cruise
control switch turns on
the indicator lamp to
indicate the cruise
control system is
activated.
Water Separator Warning Light
This lamp comes on to warn the driver of
water in the fuel tank which causes the
loss of engine power. When a certain
amount of water is accumulated, the lamp
comes on and a chime sounds.
Engine CHECK Warning Light
This warning light comes on when
the ignition switch is turned to "ON"
position and should go out if the
system related to engine control is
normal.
This comes on when different
sensors and devices related to
engine control are defective.
Winter Mode
Indicator
Pressing the "W" side of the
automatic transmission mode
selector switch switches the
driving mode to winter mode and
turns on the indicator lamp.
Use this mode to drive off
smoothly on icy and slippery
roads.
Charge Warning Light
This warning light comes on when the
ignition switch is turned on and go off
when the engine is started.
If this light doesn't go off after engine
starting, it means there is a malfunction in
the system.
Engine Hood Open Warning Light
When the engine hood is open, this light
comes on to inform the driver.

TCU ▶
TCU is located under the driver's seat and controls the operations of transmission.
TCU receives the ignition voltage and has three connectors (16-pin, 12-pin, 20-pin).
TCU receives input signals from certain transmission-related sensors, gear select lever and
inhibitor switch. TCU also uses these signals when determining transmission operating strategy.
TCU uses PCAN to communicate with other units. And, TCU communicates with engine ECU,
ESP unit, TCCU and instrument cluster through CAN lines to control the gear shifting and to
recognize the current gear position.
DSI M78 Automatic Transmission is based on the transmission in the vehicle with D20DT engine
for EURO III or EURO IV or EURO V.
Differences: changed some components (torque converter and torque converter housing, some
pinion gears, sun gear), increased torsional damping force.
