STEERING -On-vehicle Service37A-9
POWER STEERING FLUID LEVEL CHECK
1. Park the vehicle on a flat, level surface, start the engine,
and then turn the steering wheel several times to raise
the temperature of the fluid to approximately 50 - 60_C.
2. With the engine running, turn the wheel all the way to
the left and right several times.
3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine
is stopped, and while it is running. If the change of the
fluid level is 5 mm or more, air bleeding should be done.
POWER STEERING FLUID REPLACEMENT
1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the
oil into a container.
4. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
5. While operating the starting motor intermittently, turn the
steering wheel all the way to the left and right several
times to drain all of the fluid.
6. Connect the return hoses securely, and then secure it
with the clip.
7. Fill the oil reservoir with specified fluid up to the lower
position of the filter, and then bleed air.
Specified fluid:
Automatic transmission fluid DEXRONII
Caution
Do not use ATF-SPIIM and ATF-SPIII.
POWER STEERING SYSTEM BLEEDING
1. Jack up the vehicle and support the front wheels with
rigid racks.
2. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
3. Cranking the engine with the starter several times
intermittently (during 15 to 20 seconds), turn the steering
wheel left and right fully five or six times.
Caution
(1) During the bleeding, refill the fluid so that the
level never falls below the lower position of the
filter.
(2) Be sure to bleed air only while cranking. If the
bleeding is done with the engine running, the air
will be broken up and absorbed into the fluid.
4. Connect the ignition coil connectors and idle the engine.
5. Turn the steering wheel left and right fully until no bubbles
comes out in the oil reservoir.
6. See that the fluid is not milky and that the fluid level
is up to the specified position on the level gauge.
7. See that the fluid level changes little when the steering
wheel is turned left and right.
8. Check difference in fluid levels between the engine
stopped and running.

9. If the level changes more than 5 mm, the air is badly
bled. So, bleed air again.
Caution
(1) If the fluid level rises suddenly after the engine
is stopped, the bleeding is incomplete.
(2) Incomplete bleeding causes abnormal noises
from the pump and the flow-control valve. This
could lessen the life of the pump and the other
parts.
OIL PUMP PRESSURE TEST
1. Disconnect the pressure hose from the oil pump, and
then connect the special tools.
2. Bleed the air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50 - 60_C.
3. Start the engine and idle it at 1,000±100 r/min.
4. Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure to confirm that it
is within the standard value range.
Standard value: 8.4 - 9.0 MPa
5. If the standard value is not met, the oil pump is defective.
So, replace the oil pump. Then, measure oil pressure
again.
6. With the pressure gauge shut - off valve fully open, check
the hydraulic pressure in unladen condition.
Standard value: 0.2 - 0.8 MPa
7. If the standard value is not met, the oil line or steering
gear is probably defective. So, repair and measure oil
pressure again.
8. Turn the steering wheel fully either left or right and check
the retention hydraulic pressure.
Standard value: 8.4 - 9.0 MPa
9. If the pressure is below the standard value, disassemble
and reassemble the steering gear. If above, replace the
oil pump. Then, measure oil pressure again.
10. Remove the special tools, and tighten the pressure hose
to the specified torque.
Tightening torque: 18±3 N·m
11. Bleed the system.

INPUT SIGNAL CHECK
1. Check the inputs using MUT-II or a voltmeter. (Refer to GROUP 00 - How to Use
Troubleshooting/Inspection Service Points.)
2. The following input signals can be checked using MUT-II or a voltmeter connected to the diagnosis
connector.
NOTE
When fault is detected during input signal inspection, refer to Trouble Symptom Chart to perform
troubleshooting. (Refer to P.54B-7).
