5) Advantages
Improved torque response by using 3-stage type spring: Strengthens the torque response in
all ranges (low, medium, and high speed) by applying respective spring constant at each
range.
Stable revolution of the primary and secondary wheel by using planetary gear: Works as
auxiliary damper against spring changes
Less heat generation due to no direct friction against spring surface: Plastic material is
covered on the spring outer surface
Increased durability by using plastic bushing (extends the lifetime of grease) -

6) Drive Plate
Drive plate receives the power from the start motor when starting the engine. With this, the drive
plate initially drives the power train system. And, it is connected to the torque converter to transfer
the engine torque to the power train system.

2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston
speed and crankshaft angle based on input data and stored specific map to control the engine
power and emission gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure
and activates injector solenoid valve to control the fuel injection period and injection timing; so
controls various actuators in response to engine changes. Auxiliary function of ECU has adopted
to reduce emission gas, improve fuel economy and enhance safety, comforts and conveniences.
For example, there are EGR, booster pressure control, autocruise (export only) and immobilizer
and adopted CAN communication to exchange data among electrical systems (automatic T/M
and brake system) in the vehicle fluently. And Scanner can be used to diagnose vehicle status
and defectives.

water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied
instantly so there is injector drive circuit in the ECU to generate necessary current during injector
drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and
hold-current-phase and then the injectors should work very correctly under every working
condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper
injection volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and
engine cranking speed. Starting injection continues from when the ignition switch is turned to
ignition position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel
and engine rpm and the drive map will be used to match the drivers inputs with optimum
engine power. -

B. Driver Demand
The driver demand is the translation of the pedal position into the fuel demand. It is calculated as
a function of the pedal position and of the engine speed. The driver demand is filtered in order to
limit the hesitations caused by rapid changes of the pedal position. A mapping determines the
maximum fuel which can be injected as a function of the driver demand and the rail pressure.
Since the flow is proportional to the injection time and to the square root of the injection pressure,
it is necessary to limit the flow according to the pressure in order to avoid extending the injection
for too long into the engine cycle. The system compares the driver demand with this limit and
chooses the smaller of the 2 values. The driver demand is then corrected according to the
coolant temperature. This correction is added to the driver demand.

Check whether the multifunction wiper switch is in the "AUTO" position.
Check the power to the sensor. Check the conditions of the pin 3 (Ground) and the pin
4 (IGN).
Check the wiper relay for defective. 1)
2)
3) Symptom 2. It rains but the system does not work in "AUTO" position. TROUBLE SHOOTING ▶
The wiper does not operate one cycle when turning the multifunctio
n
wiper switch to the "AUTO" from the "OFF" position or starting the engine
while the wiper switch is in the "AUTO" position.
When starting the engine with the multifunction wiper switch in the "AUTO" position,
the wiper operates one cycle to remind a driver that the wiper switch is in the "AUTO"
position.
When the multifunction wiper switch is turned to "AUTO" from "OFF", the wiper
operates one cycle.
It always operates one cycle for the initial operation, however, the wiper does not
operate afterwards to prevent the wiper blade wear if not raining when turning the
wiper switch to "AUTO" from "OFF". However, the wiper operates up to 5 minutes
after rain stops. If this function does not occur, check No. 8 pin. If the pin is normal,
check the wiper relay related terminals. 1)
2)
Symptom 3. The wiper operates 3 or 4 times at high speed abruptly.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount
of rain drops. Therefore, change the knob to low sensitivity.
Symptom 4. The wiper operates continuoulsy even on the dry windshield glass.
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly
and clearly, this problem could be occurred. In this case, replace the wiper blade
with new one.
Check whether the variable resistance knob on the multifunction wiper switch is set
in "FAST" The "FAST" is the highest stage of sensitivity and very sensitive to small
amount of rain drops. Therefore, change the knob to low sensitivity. 1)
2) Symptom 1.

The door lock system outputs "LOCK" when the vehicle speed maintains over 30 km/h.
However, it doesn't output "LOCK" when all doors are locked or failed.
If any of doors is unlocked after outputting "LOCK" in step 1, outputs "LOCK" up to 5 times
(except step (1)) at the interval of one second.
If any of doors is unlocked after 5 times of "LOCK" outputs, the door
(driver's/passenger's/rear) is regarded as "FAIL".
If the door that was regarded as fail is changed (UNLOCK to LOCK), it will be recognized
as a normal one.
If any door is regarded as FAIL, the auto door lock function does not work. (if it is
occurred when the vehicle speed is over 30 km/h, the auto door lock output does not
occur even if the vehicle speed falls below 30 km/h and accelerates again to over 30
km/h.) Nonetheless, the central door lock function works properly.
When the system receives "UNLOCK" signal from a door switch, it outputs "LOCK" signals
5 times. If additional "LOCK" signal from another door switch is detected during the
period, the system outputs five "LOCK" signals 5 times for the switch.
The door lock system outputs "UNLOCK" automatically if the "LOCK" output conditions are
established by this function or the key is cycled (IGN=OFF) (even when there is no "LOCK"
output while the vehicle speed maintains over 30 km/h under lock condition).
(If the LOCK condition is established with the ignition switch ON, the system outputs
UNLOCK signal unconditionally when turning the ignition switch to OFF position.)
However, when the ignition key is turned to "OFF" position, the lock output conditions will
be cancelled.
The "FAIL" condition of the door will be erased when the ignition key is turned to "OFF"
position. 1.
