STEERING -On-vehicle Service37A-10
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.

ADJUSTMENTS AND REPLACEMENT DURING
POWER WINDOW MALFUNCTION
If the window glass does not rise but automatically descends,
adjust and replace the window glass as follows:
1. Remove the door trim and waterproof film. (P.42-27)
2. Remove the window regulator assembly from the door
window glass, and raise and lower the window glass with
your hand and check the operating force.
Remarks Insert a cushion, etc. to prevent damage of
the glass if it accidentally drops.
3. If the door window glass does not rise and descend
smoothly, perform the following check and repair.
DCheck the installation condition of the runchannel.
DStraighten twist in the door sash.
DCheck the installation condition of the lower sash
or the center sash.
NOTE
The lower sash cannot normally be adjusted, but it may
be possible to adjust the sash span slightly within the
range allowed by manufacturing tolerances by pushing
the lower sash outwards while re-installing it.
4. If repair or adjustment is not possible, replace the door
assembly.
POWER WINDOW SAFETY MECHANISM
CHECK
1. Set a wood piece of about 10 mm thick as shown in
the figure, and raise the window glass.
2. Check that the window glass descends by about 150
mm when it catches the wood piece. If it does not, perform
troubleshooting. (Refer to GROUP 54B.)
POWER WINDOW TIMER FUNCTION CHECK
9Close the door and turn the ignition switch in the OFF position,
and then check the power window operates for 30 seconds.
If it does not, perform troubleshooting.(Refer to GROUP 54B.)
