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.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Before replacing or repairing air conditioning components, first determine if the malfunction is due to the refrigerant
charge, air flow or compressor.
Use the table below to help you find the cause of the problem. The numbers indicate the priority of the likely cause of
the problem. Check each part in order. If necessary, replace these parts.
After correcting the malfunction, check the complete system to ensure that performance is satisfactory.

b. HECU
During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such phenomena are
due to intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking and is
not an abnormality.
DETECTING CONDITION
Trouble Symptoms Possible Cause
Brake operation varies depending on driving conditions and road
surface conditions, so diagnosis can be difficult.However if a normal
DTC is displayed, check the following probable cause. When the
problem is still occurring, replace the ABS control module. a.
Inoperative power source circuit
b. Inoperative wheel speed sensor circuit
c. Inoperative hydraulic circuit for leakage
d. Inoperative HECU
