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
±
7 N

11. Bleed the system (Refer to P.37-13 ).
POWER STEERING PRESSURE SWITCH
CHECK
M1372007200324
1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•
MB990662: Power Steering Oil Pressure Gauge
•
MB991548: Power Steering Oil Pressure Gauge
Adapter (pump side)
•
MB991549: Power Steering Oil Pressure Gauge
Adapter (hose side)
2. Bleed 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. The engine should be idling.
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.
Tightening torque: 57

8. Bleed the system (Refer to P.37-13 ).
TIE ROD END BALL JOINT DUST COVER
CHECK
M1372008600262
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
M1372013500090
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.
