DESCRIPTION
Oil Temperature Sensor
The oil temperature sensor is of the thermistor type, and senses the automatic transaxle fluid temperature. Using the
signal from this sensor, TCM(PCM) controls the shift pattern optimally during shift. In order to operate the damper
clutch, this signal is also referred.

CHECKING POWER STEERING BELT TENSION
Refer to EM group(Timing system).
CHECKING POWER STEERING FLUID LEVEL
1.Position the vehicle on a level surface.
2. Start the engine. With the vehicle kept stationary, turn the steering wheel several times continuously to raise the
fluid temperature to 50- 60°C (122 - 140°F).
3. With the engine at idle, turn the steering wheel fully clockwise and counter- clockwise several times.
4. Make sure that there is no foaming or cloudiness in the reservoir fluid.
5. Stop the engine and check for any difference in fluid level between a stationary and a running engine.
a.If the fluid level varies 5 mm (0.2 in) or more, bleed the system again.
b. If the fluid level suddenly rises after stopping the engine, further bleeding is required.
c. Incomplete bleeding will produce a chattering sound in the pump and noise in the flow control valve, and
lead to decreased durability of the pump.
REPLACING POWER STEERING FLUID
1.Jack up the front wheels and support them with jackstands.
2. Disconnect the return hose from the oil reservoir and plug the oil reservoir.
3. Connect a vinyl hose to the disconnected return hose, and drain the oil into a container.
4. Remove the fuel pump fuse, then start the engine and wait for the engine to stall. Next, while operating the starting
motor intermittently, turn the steering wheel all the way to the left and then to the right several times to drain the
fluid.
5. Connect the return hoses, then fill the oil reservoir with the specified fluid.
6. Reinstall the fuel pump fuse.
7. Start the engine. Check for oil leakage.
8. Stop the engine.
9. Bleed the system.
Power steering fluid type : PSF - 3
Total quantity : Approx 1.1 liter
AIR BLEEDING
1.Remove the fuel pump fuse, then start the engine and wait for the engine to stall. Next, while operating the starting
motor intermittently (for 15 ~ 20 seconds), turn the steering wheel all the way to the left and then to the right five or
six times.

a.During air bleeding, replenish the fluid supply so that the level never falls below the lower position of the
filter.
b. If air bleeding is done while the vehicle is idling, the air will be broken up and absorbed into the fluid. Be
sure to do the bleeding only while cranking.
c. Reinstall the fuel pump fuse, and start the engine(idling).
d. Turn the steering wheel to the left and the right until there are no air bubbles in the oil reservoir.
Do not hold the steering wheel turned all the way to either side for more than ten seconds.
e. Confirm that the fluid is not milky, and that the level is up to the position specified on the level gauge.
f. Confirm that there is little change in the surface o the fluid when the steering wheel is turned left and right.
a. If the surface of the fluid changes considerably, air bleeding should be done again.
b. If the fluid level rises suddenly when the engine is stopped, it indicates that there is still air in the
system.
c. If there is air in the system, a jingling noise may be heard from the pump and the control valve
may also produce unusual noises. Air in the system will shorten the life of the pump and other
parts.
OIL PUMP PRESSURE TEST (OIL PUMP RELIEF PRESSURE)
1.Disconnect the pressure hose from the oil pump. Connect the special tool between the oil pump and pressure hose
as illustrated.
2. Bleed the air, and then start the engine and turn the steering wheel several times so that the fluid temperature
rises to approximately 50°C (122°F).
3. Set the engine speed to 1,000 rpm.
4. Close the shut- off valve of the special tool and measure the fluid pressure to confirm that it is within the range.
standard vaule :
Relief pressure: 90 +3/- 2 kgf/cm²
Don’t keep the shut- off valve on the pressure gauge closed for longer than seconds.

INSTRUCTIONS
WHEN HANDLING REFRIGERANT
1. R- 134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite. When
handling the refrigerant, be sure to wear gloves.
2. It is standard practice to wear goggles or glasses to protect your eyes, and gloves to protect your hands. If the
refrigerant splashes into your eyes, wash them with clean water immediately.
3. The R- 134a container is highly pressurized. Never leave it in a hot place, and check that the storage temperature
is below 52°C (126°F)
4. An electronic leak detector should be used to check the system for refrigerant leakage. Bear in mind that the R-
134a, upon coming into contact with flame, produces phosgene, a highly toxic gas.
5. Use only recommended the lubricant for R- 134a systems. If lubricants other than the recommended one used,
system failure may occur.
6. PAG lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be
observed:
a. When removing refrigerant components from a vehicle, cap immediately the components to prevent from the
entry of moisture.
b. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the
components.
c. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking
on moisture.
d. Use the recommended lubricant from a sealed container only.
7. If an accidental discharge in the system occurs, ventilate the work area before resuming service.
WHEN REPLACING PARTS ON A/C SYSTEM
1.Never open or loosen a connection before discharging the system.
2. Seal the open fittings of components with a cap or plug immediately to prevent intrusion of moisture or dust.
3. Do not remove the sealing caps from a replacement component until it is ready to be installed.
4. Before connecting an open fitting, always install a new sealing ring. Coat the fitting and seal with refrigerant oil
before making the connection.

DESCRIPTION
This specification applies to HCU(Hydraulic Control Unit) and ECU(Electronic Control Unit) of the HECU.(Hydraulic and
Electronic Control Unit)
This specification is for the wiring design and installation of ABS/TCS/ESC ECU.
This unit has the functions as follows.
a. Input of signal from Pressure sensor, Steering angle sensor, Yaw & Lateral G sensor, the wheel speed sensors
attached to each wheel.
b. Control of braking force / traction force/ yaw moment.
c. Failsafe function.
d. Self diagnosis function.
e. Interface with the external diagnosis tester.
Installation position : engine compartment a. Brake tube length from Master cylinder port to HECU inlet port should be max. 1m
b. The position should not be close to the engine block and not lower than the wheel.
OPERATION
The ECU shall be put into operation by switching on the operating voltage (IGN).
On completion of the initialization phase, the ECU shall be ready for operation.
In the operating condition, the ECU shall be ready, within the specified limits (voltage and temperature), to process the
signals offered by the various sensors and switches in accordance with the control algorithm defined by the software
and to control the hydraulic and electrical actuators.
Wheel Sensor signal processing
The ECU shall receive wheel speed signal from the four active wheel sensors.
The wheel signals are converted to voltage signal by the signal conditioning circuit after receiving current signal from
active wheel sensors and given as input to the MCU.
Solenoid Valve Control
When one side of the valve coil is connected to the positive voltage that is provided through the valve relay and the
other side is connected to the ground by the semiconductor circuit, the solenoid valve goes into operation.
The electrical function of the coils are always monitored by the valve test pulse under normal operation conditions.
Voltage limits
a.Overvoltage
When overvoltage is detected(above 16.8 V), the ECU switches off the valve relay and shuts down the system.
When voltage is returned to operating range, the system goes back to the normal condition after the initialization
phase.
b. Undervoltage
In the event of undervoltage(below 9.3 V), ABS control shall be inhibited and the warning lamp shall be turned on.
When voltage is returned to operating range, the warning lamp is switched off and ECU returns to normal operating
mode.
Pump Motor Checking
The ECU performs a pump motor test at a speed of 15km/h once after IGN is switched on.
Diagnostic Interface
Failures detected by the ECU are encoded on the ECU, stored in a EEPROM and read out by diagnostic equipment
when the ignition switch is turned on.
The diagnosis interface can also be used for testing the ECU during production of the ECU and for actuating the HCU
(Air - bleeding line or Roll and Brake Test line).
