Symptom Troubleshooting
1. Check the power assist (see page 17-7).
Go to step 2.
Power assist is OK.
2. Measure steady-state fluid pressure from the pump
at idle with T/N 07406-0010001 (see step 9 on page
17-9) or T/N 07406-001000A (see step 8 on page 17-
10).
Go to step 3.
Go to step 7.
3. Measure the pump relief pressure at idle with
T/N 07406-0010001 (see step 10 on page 17-9) or
T/N 07406-001000A (see step 9 on page 17-10).
Go to step 4.
Go to step 8.
4. With a spring scale, measure the power assist in
both directions, to the left and to the right.
Go to step 5.
Go to step 9.
5. Measure the fluid pressure with T/N 07406-0010001
(see step 11 on page 17-9) or T/N 07406-001000A
(see step 10 on page 17-10) with both pressure
gauge valves open (if so equipped), while turning
the steering wheel fully to the left and fully to the
right.
Go to step 6.
Replace the gearbox.
6. Adjust the rack guide (see page 17-29), and retest.
Repair is completed.
Replace the gearbox.
7. Check for feed and return lines between the pump
and the gearbox for clogging and deformation.
Repair or replace the lines.
Replace the valve body unit.
8. Check the flow control valve (see page 17-17) for
smooth movement and leaks.
Replace the pump assembly.
Replace the flow control valve.
9. Check the cylinder lines A and B for deformation
(see page 17-34).
Replace the lines.
Go to step 10.
10. Check for a bent rack shaft or misadjusted rack
guide (too tight).
Replace the rack shaft or readjust the rack
guide.
Replace the valve body unit.
Is the power assist mor e than 29 N ( 3.0 kgf ,
6.6 lbf )?
Is the pr essur e 1,500 kPa ( 15 kgf / cm , 213 psi) or
less?
Is the pr essur e 8.300 8.800 kPa ( 85 90 kgf / cm ,
1.210 1.280 psi) or less?
Ar e the two measur ements within 5.0 N ( 0.51 kgf ,
1.12 lbf ) of each other ?
Is the pr essur e 8.300 8.800 kPa ( 85 90 kgf / cm ,
1.210 1.280 psi) or less?
Is the steer ing OK ?
Ar e the lines clogged or def or med?
Is the f low contr ol valve OK ?
Ar e the A or B lines def or med?
