OIL PUMP PRESSURE TEST

M1372002300296

1. Disconnect the pressure hose from the oil pump, 

and then connect the following special tools.

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 

-

 2.0 MPa

7. Remove the special tools, and then tighten the 

pressure hose to the specified torque.

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.
