(3) CIRCUIT DESCRIPTION
A. FUNCTION
TCU controls the gear groups according to the driving conditions. It receives the driving data
from many sensors and switches as input signals. It is also connected with ECU,
HECU,instrument panel and selector lever control unit.
▶Shifting Method
Basic shift operation includes up-shift and down-shift for all gear groups. The shift control
unit determines driving resistance, accelerator pedal position, vehicle speed and some
parameters (road surface condition, up hill and down hill gradients, trailer driving
conditions, catalytic converter conditions, driving habits and automatic transmission oil
temperature) to select a shift gear.
▶Down Shift
When engine speed increases excessively, the down shift does not occur. To get an
engine brake effect during downhill driving, the current gear is maintained in speed control
mode.
▶Engine RPM Adjustment
During shifting, the engine torque is reduced to optimize the shift operation by delaying the
ignition time.
▶Lock-Up Clutch Control
The lockup clutch in torque converter is activated in 3rd, 4th and 5th gear and operates in
sequence via PWM solenoid valve.
▶Others
The transmission is automatically controlled to compensate durability and wear.
The shift control values such as shifting point, shifting time, pressure during shifting, and
lockup clutch control are permanently saved and the diagnosis is partially available.
B. MODE SWITCH
▶Function
The mode switch is installed beside the selector lever and it has two modes of “S”
mode (Standard Mode) and “W” mode (Winter Mode).
“S” mode is used in normal driving (starts off with 1st gear). TCU (Transmission
Control Unit) provides pleasant driving by changing the shifting pattern according to
the driving habits (downhill gripping: approx. 11 ~ 13.5 %)
When “W” mode is selected, the Winter mode indicator in meter cluster comes
on, and the vehicle starts off with 2nd gear to achieve smooth starting on the icy o
r
slippery road.
-
-
In winter mode, the up shift becomes faster and the down shift becomes slower fo
r
improving fuel consumption. The “W” mode is automatically changed to “S” mode in
full throttle or kick-down operation. The vehicle can starts off with 2nd reverse gear (gea
r
ratio: 1.92 ~ 1.93) when the “W” mode is selected. It is very useful on icy and
slippery road. However, in this case, the “W” switch should be selected before
placing the selector lever to “R” position.
Even though “W” mode is selected, the vehicle starts off with 1st gear in following:
When the system recognizes the mode switch operation, the selector lever control unit
sends the control signal TCU via CAN communication.
When the selector lever is in “1” position.
When fully depressing the accelerator pedal or when starting off with kick-down
condition.

C. REVERSE/PARKING (R/P) LOCK SYSTEM
Reverse (R) lock system is a safety system that prevents the selector lever from shifting to “P”
or “R” position by activating the solenoid valve when the selector lever unit determines
that the vehicle speed exceeds 10 km/h by checking the speed signal from wheel speed senso
r
via CAN communication. Parking (P) lock system uses the signals from brake switch other than
conventional cable system to shift to other positions. The wiring harness for detecting brake
switch operation is connected to selector lever control unit.
D. STARTER LOCK-OUT CONTACT SWITC
The starter lock-out contact is installed beside oil temperature sensor and is actuated by a cam
rail, which is located on the latching plate. In the selector lever positions “P” and “N”, the
permanent magnet is moved away from the reed contact. This opens the reed contact and the
transmission control module receives an electrical signal. The transmission control module
activates the starter lock-out relay module. This closes the electrical circuit to the starter in
selector lever positions “P” and “N” via the starter lock-out relay module. In other words,
when the selector lever is in driving positions, the contact is closed and the starter cannot be
operated.
E. OIL TEMPERATURE SENSOR
The oil temperature sensor is installed in hydraulic control unit and is connected in series with
the starter lock-out contact. This means that the temperature signal is transferred to TCU when
the starter lock-out contact is closed. The oil temperature has a considerable effect on the
shifting time and therefore the shift quality. By measuring the oil temperature, shift operations
can be optimized in all temperature ranges.

G. LOCKUP SOLENOID VALVE
This valve activates and releases the lockup
clutch by adjusting the current to solenoid valve
according to engine throttle opening value and
output shaft speed. The lockup clutch operates
in 3rd, 4th and 5th gear with steps to reduce
shift shocks.

C. HBA (HYDRAULIC BRAKE ASSIST SYSTEM)
HBA (Hydraulic Brake Assist) system helps in an emergency braking situation when the
driver applies the brake fast, but not with sufficient pressure, which leads to dangerously long
braking distance. ECU recognizes the attempt at full braking and transmits the signal calling
for full brake pressure from the hydraulic booster. An inexperienced, elderly or physically
weak driver may suffer from the accident by not fully pressing the brake pedal when hard
braking is required under emergency. The HBA System increases the braking force unde
r
urgent situations to enhance the inputted braking force from the driver.
D. SWAS : STEERING WHEEL ANGLE SENSOR
The steering wheel angle sensor is located between clock spring and multifunction switch.
This sensor is used for recognition of driver’s intends. If the sensor is replaced with
new one, it can detect the neutral position after the vehicle is moving over 20 km/h for more
than 5 seconds.
E. HDC (Hill Descent Control) SYSTEM
When the slope level exceeds 10%, the HDC operates until the vehicle reaches the speed
condition given in step (4).
When the slope level is between 10% and 20% during the HDC operation
▶
When depressing the accelerator pedal or brake pedal, HDC system is changed to
stand-by mode. When depressing the accelerator pedal again, HDC starts its operation
again. Therefore, drivers can control the vehicle speed to a desired level by operating
the accelerator pedal.
When the slope level exceeds 20% during the HDC operation
▶
When depressing the accelerator pedal, HDC system is changed to stand-by mode.
When depressing the brake pedal, HDC continues its operation and the braking power is
increased. In this case, HECU sounds an abnormal noise and brake pedal may be very
rigid, but this is a normal condition due to HDC operation.
(3) CIRCUIT DESCRIPTION
A. ABS COMPONENTS
Newly introduced ABS has a different shape of integrated hydraulic modulator and HECU
(Hydraulic and Electronic Control Unit) compared to existing ABS. And, the wheel speed
sensor uses different method to detect wheel speed. The basic function of the ABS that
maintains the vehicle stability by controlling the steerability of the vehicle when braking has
not been changed.
B. ACTIVE WHEEL SPEED SENSOR
The speed sensor used in traditional ABS is made of permanent magnet and transmits the
output voltage that changes as the wheel rotor rotates to the HECU system. New wheel
speed sensor detects the wheel speed through the current value that depends on the
resistance that changes according to the magnetic field by using four resisters and supplying
the 12 V power supply to the sensor.

F. INPUT/OUTPUT SIGNALS FOR HDC OPERATION G. OPERATION OF HDC INDICATOR CONTROLLER
This table describes the coming-on and blinking mode of HDC indicator according to the HDC
switch operation (ON/OFF). The HDC indicator on the instrument panel has two modes;
green (function lamp) and red (warning lamp). The HDC switch is a push & self return type
switch ? when you press it once, it starts to operate and when you press it again, it stops the
operation.
H. ESP (ELECTRONIC STABILITY PROGRAM)
ESP (Electronic Stability Program) recognizes critical driving conditions, such as panic
reactions in dangerous situations, and stabilizes the vehicle by wheel-individual braking and
engine control intervention with no need for actuating the brake. This system is developed to
help the driver avoid the danger of losing the control of the vehicle stability due to understeering or over-steering during cornering.

K. ESP WARNING LAMP BLINKING IN CONTROL
ESP warning lamp blinks when ESP control is activated. If the activation reaches a certain
limitation, a beep sounds to warn the driver. The ESP warning lamp goes off when ESP
function is deactivated. Even when the ESP is operated for a very short period of time, the
ESP warning lamp blinks minimum of 4 times every 175 milliseconds and the buzzer sounds
for at least 1.4 seconds with 100 ms interval.
L. ESP SYSTEM CANCELLATION USING THE ESP OFF SWITCH
When the ESP switch at the center switch panel is pushed (for over approximately 150 ms),
the ESP system will be cancelled and the vehicle will be driven regardless of the output
values from the corresponding sensors. Then, the ESP warning lamp on the instrument panel
comes on.
M. RESUMING THE ESP SYSTEM BY USING THE ESP OFF SWITCH
The ESP system will be resumed and the ESP warning lamp at the instrument panel goes of
f
when the ESP switch at the center switch panel is pushed (for over approximately 150 ms)
while the ESP system is not operating.

3) CIRCUIT DESCRIPTION
(1) SSPS (SPEED SENSITIVE POWER STEERING)
In the conventional constant power assist steering system, the steerability gets lighter as
vehicle speed rises, and this may cause a dangerous situation. Where as having heavy
steerability in high speed driving makes it difficult to manipulate the steering wheel when
vehicle is in stop. This steering system solves this problem as the steerability is changed
according to the vehicle speed, which is called Speed Sensitive Power Steering (SSPS).
SSPS, by providing appropriate steerability to a driver according to the changes of vehicle
speed, gives steering stability. The power steering control unit adjusts the hydraulic pressure
to reaction plunger by controlling the pressure solenoid valve located in the gear box to
optimize the steerability. In other words, the steering wheel gets lighter by adjusting
steerability in stop or low speed and provides steering stability by adjusting steering wheel to
become heavier in high speed.
(2) INPUT/OUTPUT OF SSPS CONTROL UNIT
(3) SSPS CONFIGURATION
A. PCV (Pressure Control Valve)
This valve controls the hydraulic pressure supplied to reaction device by moving the spool
valve according to the changes of solenoid valve.
B. Reaction device
This device increases the steerability effect by binding the input shaft with supplied hydraulic
pressure from PCV.
C. Solenoid valve
The SSPS control unit controls the amount of electric current to the solenoid valve according
to the vehicle speed. In other words, the solenoid valve controls the hydraulic pressure
applied to reaction plunger by changing the valve spool position that is linked with solenoid
valve according to the amount of electric current. The changes of hydraulic pressure applied
to input shaft according to the pressure changes applied to the reaction plunger provide
proper steerability based on the amount of electric current.
Specifications
▶
Electric Current Check
▶
Disconnect the solenoid valve connector (waterproof connector) and install the
ammeter between the solenoid valve connector and the wiring harness.
·
Do not ground the solenoid terminal.-
When the vehicle speed is at 0 km/h, check whether the electric current for solenoid
is in specified range and check that the current is reduced as the vehicle speed
increases.
-
D. SSPS Control Unit
To provide proper steerability to a driver, the SSPS control unit controls the solenoid
valve by receiving the vehicle speed and the throttle position data via CAN
communication.
The SSPS control unit controls the working current for the solenoid valve with PWM type
duty ratio of 333 Hz frequency and sets the target current to 1A during 1 second after the
ignition is “ON”.
When a trouble occurs in the system, the SSPS control unit generates a trouble code
using fail safe function.

▶Engine Tachometer
The tachometer indicates engine speed in revolutions per minute. Multiply 1,000 to the
current number, then it will be the current number of engine revolutions.
Under the normal engine operating temperature, the proper idling speed is 750 ±
50 rpm for D27DT engine. The red zone (danger rpm range) starts from 4,500 rpm.
Connect the tachometer for tune-up test and start the engine.
Eliminate the hysteresis by tapping the tachometer.
Compare the values on the tester and tachometer and replace the tachometer if the
tolerance is excessive.

▶Speedometer Gauge
The speedometer indicates the vehicle speed by calculating the signals from the rea
r
wheel speed sensors through ABS or ESP unit (speed signal cycle: 21 ms). If the
speedometer gauge vibrates, stops at a certain range or makes an abnormal noise, there
could be defectives in speedometer. However, these symptoms also could be occured
when the tire has uneven wear, different tire inflation pressures or different tire
specifications. Perform the speedometer test regarding the tolerance as described.
However, it is not similar simple work in field due to lack of measuring conditions such as
test equipment and preciseness.
Check the allowable tolerance of the speedometer and operations of the trip odometer
by using atester.
Check if the speedometer gauge is shaking and the abnormal noise sounds.
Eliminate the hysteresis by tapping the speedometer.

▶Fuel Level Gauge
The fuel level gauge displays the resistance value of the float on the fuel sender in the
fuel tank through a pointer. Note that this vehicle doesn't have a service hole fo
r
checking the fuel sender connector in the fuel tank. The fuel sender and its connecto
r
can be checked and replaced only when the fuel tank is removed. The power supply and
resistance value should be measured at the connector in front of the fuel sender (refer to
wiring diagram). When the power supply and output resistance are normal, the float
operation by fuel level may be defective; if so, replace the fuel sender.
▶Tolerance and resistance value by indicating angle
This table shows the tolerance and resistance value changes by fuel level in normal conditions.
Therefore, the differences that can be occurred by the road conditions and fuel fluctuations are
ignored.
▶Coolant Temperature Gauge
Using a needle, it displays the coolant temperature obtained from the engine coolant
temperature sensor. The PTC resistance value of the coolant temperature sensor is
transmitted to the engine ECU and then to the cluster as CAN signal. The angle o
f
guage that can be varied by coolant temperature is as shown below.
▶Measurement of coolant temperature sensor resistance
Measure the resistance between the terminal and the ground with an ohmmeter and
replace if the resistance is out of specified range.
Resistance value by coolant temperature: 20°C - 2449Ω ± 5 %
50°C - 826Ω ± 5 %
80°C - 321Ω ± 5 %
100°C - 12Ω ± 5 %
When the resistance value by coolant temperature is within the specified range, check
thermostat, water pump, radiator related coolant circuit for normal operation.
A
lso,
check the wiring harnesses and connectors for proper connection (D27DT engine
ECU: NO.101, 102 / D27DTP (power up) engine ECU: A56, A57).
The time when the engine coolant temperature reaches the normal temperature
(gauge indicating angle: 0°) depends on the ambient temperature and the
vehicle's load. Therefore, the coolant temperature gauge should be used only fo
r
reading its movement.
