DIAGNOSTIC INFORMATION AND PROCEDURES
POWER STEERING SYSTEM
PRESSURE TEST
Tools Required
124 589 06 21 00 Power Steering Pump Testing Unit
Check the fluid pressure as follow to trouble is in the
pump or gear unit.
Test Procedure
1. Disconnect the pressure hose from the oil pump
and connect a pressure gauge between the oil
pump and pressure hose.
2. Bleed the system. Start the engine and turn the
steering wheel form lock several times until oil
temperature is up to 50 °C.
3. Run the engine at 1,000 rpm.
4. Close the gauge valve fully, and read pressure.
The pump pressure with the valve closed should
be between 7,355 kPa to 8,041 kPa (1,067 psi to
1,166 psi).
Notice: Do not keep the valve closed for more
than 10 seconds.
5. Remove the pressure gauge and connect the pres-
sure hose.
6. Do bleeding procedure.
POWER STEERING SYSTEM
LEAK TEST
General Procedure
Inspect the following :
The power steering fluid reservoir for overfill.
Fluid for aeration and overflow.
The hoses for loose connections.
The torsion bar, stub shaft and adjuster seals for
leaks.
The component sealing surfaces for damage.
Important: Verify the exact point of the leak. The point
from which the fluid is dripping is not necessarily the
point at which the system is leaking. When service is
required, clean the leak area upon disassembly,
replace the leaking seal, check the component sealing
surfaces for damage and reset the torque bolt to
specifications required.
External Leak Check
The purpose of this procedure is to pinpoint the location
of the leak. In some cases, the leak can be easily lo-
cated, but seepage-type leaks may be harder to find.
To locate seepage leaks, use the following method:
1. With the engine off, wipe dry the complete power
steering system.
2. Check the power steering fluid level in the pump’s
reservoir. Adjust the fluid level as necessary.
Refer to “Checking and Adding Fluid” in this
section.
Notice: Do not hold the steering wheel at a stop
for any length of time as this can damage the
power steering pump.
3. Start the engine. Turn the steering wheel counter-
clockwise and clockwise from stop to stop several
times.
4. Find the exact area of the leak and repair it.

BLEEDING THE POWER
STEERING SYSTEM
1. Disconnect the fuel line. Using a starter motor,
crank the engine and turn the steering wheel from
lock to start 5 or 6 times.
Notice: Do bleeding with engine cranking. If bleed
with idling, there can be a air contact with oil.
2. Connect the fuel feed line and start the engine at
idle speed.
3. Turn the steering wheel from lock to lock until there
is no more air in oil reservoir.
4. Connect the oil level is within specification.
5. By turning the steering wheel left to right, check
the oil level change.
Notice: If oil is not changes more than 5 mm, do
bleeding again. If oil level rises suddenly when
stopped engine, again.
MAINTENANCE
CHECKING AND ADDING FLUID
Notice: When adding fluid or making a complete fluid
change, always use DEXRON. - II power steering fluid.
Failure to use the proper fluid will cause hose and seal
damage and fluid leaks.
1. The power steering fluid level is indicated by marks
on a fluid level indicator on the fluid reservoir cap.
2. If the fluid is warmed up to 66 °C (150 °F), the fluid
level should be between the MAX and MIN marks.
Add fluid as needed.
3. If the fluid is cool, 21 °C (70 °F), the fluid level should
be at the MIN mark. Add fluid as needed.

STRAIGHT-AHEAD CHECK
After all the necessary operations on the steering gear
are completed (removing and installing, disassembling
and assembling), check the exact straight-ahead posi-
tion of the steering in each case.
With the vehicle on the floor, place the steering wheel
in the straight-ahead position. Mark the centerline of
both tires on the floor. Turn the steering wheel all the
way to the right and mark the new centerline of both
tires on the floor.

9T1-4 REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM
DIAGNOSTIC INFORMATION AND PROCEDURE
DIAGNOSIS TEST
Introduction
Using the service connector, possible defects in power section, input output section of internal STICS unit can be
detected and each normal status and defect mode can be checked.
Diagnosis method
1. Use buzzer for diagnosis check status output.
2. Following function outputs should not act when diagnosis switch is ON (STICS in the diagnosis socket box :
connection of No. 7 and ground No. 1)
Tail lamp ON warning (buzzer output stop, door lock/unlock output stop)
Seat belt warning (chime bell output stop)
Central door lock (door lock/unlock output stop)
3. Functions in No. 2 should be restored when diagnosis switch is OFF.
4. Check output should be made once while the diagnosis switch is ON.
5. When inputs are made by operating each different switches more than 2 continuously, make output according
to input order (buzzer ON) and trun off the buzzer for 1 second and than make other remaining outputs for
input switch.
6. Buzzer output is as follows.
T1 : 0.3 ± 0.1 sec.
T2 : 0.3 ± 0.1 sec.
T : 0.6 ± 0.2 sec.
Note:
In case of checking related devices, there will be buzzer sound if it is normal and no buzzer sound if it is
defective.

9T2-2 IMMOBILIZER SYSTEM
DESCRIPTION AND OPERATION
Immobilizer is a device disabling vehicle ignition unless
a speific key is used and designed to help prevent
vehicle theft.
Immobilizer is comprised of two devices, a key with
encoded transponder and engine control unit (ECU)
with the same encoding of the transponder. When a
key is inserted into the key hole to start vehicle and
turned to ‘ON’, the ECU reads and decodes the
transponder code and, if the same, starts the engine,
it is called immobilizer. It means immobilizer system
disables starting by stopping fuel supply if the code
in the transponder does not match the code stored in
ECU each other.
Notice:
If vehicle is equipped with immobilizer system and
the engine cranks normally but not start, check
immobilizer system first rather than ignition and
other electrical systems because it can be
disabled fuel supply of injectors by ECU due to
defective immobilizer system.
Programming of the immobilizer system will be
performed by authorized personnel only. If
following defective codes for immobilizer system
appear during diagnosis of vehicle with SCANNER,
ask immobilizer programming to authorized
personnel and actual programming should be
performed by authorized per-sonnel only.
Display of defectives relevant to immobilizer
system : SCANNER
1. No communication with transponder
2. No immobilizer programming
The transponder in the key can be damaged by
shocks of dropping or hitting other objectives, so
handle it with care.
Each supplied key has programming of code on
its own. Accordingly if ECU needs to be replaced,
replace the transponder in the key.
The vehicle equipped with immobilizer system will
never be started with remote ignition device, so
do not attempt to install it.
The immobilizer system will never be removed from
the vehicle. So never attempt to remove it to install
a remote ignition device or others.
If engine does not start during service, use every
key to start the engine and then check immobilizer
sys-tem finally.
Cases that requires immobilizer
programming
1. Replacement ECU
In this case, replace the every transponder of the
key at once.
2. Replacement of the transponder
3. Additional key for lost 1 or 2 keys
1) Clear all codes for current keys from the ECU
2) When using current key : clear code of the trans-
ponder and re-program it
3) Additional (purchased) key : perform programming
4. When lost all keys
1) Clear all memorized key codes from the ECU
2) Replace the key and key set
3) Immobilizer programming
