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: 0.2 − 0.7 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 ± 7 N⋅m

WARNING
•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.
•If there is a slack in the one-way capsule,
do not attempt to repa ir 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 col-
umn has been installed to complete this inspec-
tion procedure.
2. Ensure that the tilt lever is in the lock position.
NOTE: If not, place the tilt lever in the lock posi-
tion.
