OIL PUMP PRESSURE TEST

M1372002300296

1. Disconnect the pressure hose from the oil pump,

and then connect the following special tools.

MB991548: Power Steering Oil Pressure Gauge
Adapter (Pump Side)

2. Bleed air, 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 750

–

100 r/min.

CAUTION

The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.
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. Open it again immediately after checking
the pressure.

Standard value: 8.8

-

9.5 MPa

5. If it is not within the standard value, replace the oil

pump.

6. Check whether or not the hydraulic pressure is the

standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.

Standard value: 0.8

-

1.0 MPa

7. If it is not within the standard value, the probable

cause is a malfunction of the oil line or steering
gear, so check these parts and repair as
necessary.

8. Turn the steering wheel all the way to the left or

right; then check whether or not the retention
hydraulic pressure is the standard value.

Standard value: 8.8

-

9.5 MPa

9. If not the standard value, overhaul the steering

gear. Remeasure fluid pressure.

10. Remove the special tools, and then tighten the

pressure hose to the specified torque.

Tightening torque: 57

4. Disconnect the connector for the oil pressure

switch, and place an ohmmeter at the switch.

5. Gradually close the shut-off valve of the pressure

gauge and increase the hydraulic pressure, then
check whether or not the hydraulic pressure that
activates the switch is the standard value.

Standard value: 1.5

-

2.0 MPa

6. Gradually open the shut-off valve and reduce the

hydraulic pressure; then check whether or not the
hydraulic pressure that deactivates the switch is
the standard value.

Standard value: 0.7

TIE ROD END BALL JOINT DUST COVER
CHECK

M1372008600240

1. Press the dust cover with your finger to check

whether the dust cover is cracked or damaged.

2. If the dust cover is cracked or damaged, replace

the tie rod end.

NOTE: If the dust cover is cracked or damaged,
the ball joint could be damaged.

STEERING COLUMN SHAFT ASSEMBLY
SHOCK ABSORBING MECHANISM
CHECK

M1372013500067

If a collision accident occurs or severe impact is
applied on the steering wheel, the collision energy
absorbing mechanism may have operated. Once the
mechanism has operated, it will be inoperative even
it has suffered no apparent damage. Determine if the
steering column shaft can be reused by the following
procedure. If the collision energy absorbing
mechanism has already operated, replace the
steering column shaft assembly.
If any excessive radial free play on the steering
wheel is found with the tilt lever in the lock position,
always check the steering shaft assembly.

WARNING

œ

If the vehicle continues to be driven after
the collision absorbing mechanism has
operated, the steering column shaft may
be damaged while it is in use.

œ

If there is a slack in the one-way capsule,
do not attempt to repair it but replace the
steering column shaft assembly.

Inspection Procedure

1. Remove the lower and upper column covers.

CAUTION

Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.

2. Ensure that the tilt lever is in the lock position.

NOTE: If not, place the tilt lever in the lock
position.

3. Loosen the two upper steering column mounting

bolts by two turns.

4. Hold the one-way capsules as shown, and then

try to lock them. If there is a slack in either of the
capsules, replace the steering column shaft
assembly.

NOTE: When installing a new steering column
shaft assembly, place the tilt lever in the lock
position, if it is not in place.
