INSPECTION
Oil Specification
1. The HFC- 134a system requires synthetic (PAG) compressor oil whereas the R- 12 system requires mineral
compressor oil. The two oils must never be mixed.
2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of
compressor.
Handling of Oil
1.The oil should be free from moisture, dust, metal powder, etc.
2. Do not mix with other oil.
3. The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC - 134a
Compressor Oil absorbs moisture very easily.)
4. The compressor oil must be stored in steel containers, not in plastic containers.
Compressor oil check
The oil used to lubricate the compressor is circulating with the refrigerant.
Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the
original amount of oil.
Oil total volume in system:
120±10cc (4.05±0.34 fl.oz)
Oil Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with the refrigerant in the system. When checking the amount of
oil in the system, or replacing any component of the system, the compressor must be run in advance for oil return
operation. The procedure is as follows:
1. Open all the doors and the engine hood.
2. Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position.
3. Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.
4. Stop the engine.
Replacement of Component Parts
When replacing the system component parts, supply the following amount of oil to the component parts to be installed.
Component parts to be installed Amount of Oil
Evaporator 50 cc (1.70 fl.oz)
Condenser 30 cc (1.02 fl.oz)
Receiver/dryer 30 cc (1.02 fl.oz)
Refrigerant line (One piece) 10 cc (0.34 fl.oz)
For compressor replacement, subtract the volume of oil drained from the removed compressor from the specified
volume, and drain the calculated volume of oil from the new compressor:
The specified volume - volume of removed compressor = volume to drain from the new compressor.
Even if no oil is drained from the removed compressor, don’t drain more than 50cc from new compressor.

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).

DESCRIPTION
The immobilizer system will disable the vehicle unless the proper ignition key is used, in addition to the currently
available anti- theft systems such as car alarms, the immobilizer system aims to drastically reduce the rate of auto
theft.
1. SMARTRA type immobilizer
a. The SMARTRA system consists of a transponder located in the ignition key, an antenna coil, a SMARTRA unit,
an indicator light and the PCM(ECM).
b. The SMARTRA communicates to the PCM(ECM) (Engine Control Module) via a dedicated communications line.
Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit
to control the SMARTRA.
c. When the key is inserted in the ignition and turned to the ON position, the antenna coil sends power to the
transponder in the ignition key. The transponder then sends a coded signal back through the SMARTRA unit to
the PCM(ECM).
d. If the proper key has been used, the PCM(ECM) will energize the fuel supply system. The immobilizer indicator
light in the cluster will simultaneously come on for more than five seconds, indicating that the SMARTRA unit
has recognized the code sent by the transponder.
e. If the wrong key has been used and the code was not received or recognized by the PCM(ECM) the indicator
light will continue blinking for about five seconds until the ignition switch is turned OFF.
f. If it is necessary to rewrite the PCM(ECM) to learn a new key, the dealer needs the customer's vehicle, all its
keys and the Scan tool (pro) equipped with an immobilizer program card. Any key that is not learned during
rewriting will no longer start the engine.
g. The immobilizer system can store up to four key codes.
h. If the customer has lost his key, and cannot start the engine, contact motor service station.
COMPONENTS OPERATIONS
PCM (Power Train Control Module)
1. The PCM(ECM) carries out a check of the ignition key using a special encryption algorithm, which is programmed
into the transponder as well as the PCM(ECM) simultaneously. Only if the results are equal, the engine can be
started. The data of all transponders, which are valid for the vehicle, are stored in the PCM(ECM).
