Symptom Troubleshooting
Hard Steering
1. Check the power assist (see page 17-7).
K2OA3 Engine modet:
ls the starting Ioad mote than 37.2 N (3.A kgf, 8.4
tbt)?
K2042 Engine model:
ls the starting load more than SA.e N (9.9 kgf, A.6
tbt )?
YES Go to step 2.
NO Power assist is OK.l
2. Measure steady-state fluid pressure from the pump
at idle with T/N 07406-0010001 (see page 17-9), or
TiN 07406-001000A (see page 17-10).
ls the pressure 1 ,500 kpa ( t S kgt/ctrf, 219 psi) or
less?
YES- co to step 3.
NO Go to step 7.
3. Measure the pump relief pressure at idle with T/N
07406-0010001 (see page t7-9), orT/N 07406-
001000,4 (see page 17,10).
K2043 Engine modet:
ls the pressure 6,570 7,260kpa(67-74kgf/cnf,
950
1,050 psi) or tess?
K20A2 Engine model:
Is the pressure 7,160 7,850kPa(73 80kg ctrf,
|,040 1,140 psi) or tess?
YES Go to step 4.
NO-. Faulty pump assembly. I
4, With a spring scale, measure the power assist in
both di.ections. to the left and to the right.
Are the two measurements within 2.9 N (0.3 kgf ,
0.66 lbf)of each other?
YES- co to srep S.
NO Go to step 8.
5. Measure the fluid pressure with both pressure
gauge valves open (if so equipped). while turning
the steering wheel fully to the left and fully to the
right.
K2043 Engine modet:
l6the pressure 6,570- 7,260 kpa(67
74kgl/cnf,
950
1,050 psi) or less?
K20M Engine model:
ls the ptessure 7,160- 7,850 kpa(7 g - gO kgt/cnf,
1,040 1,140 p6i)or tess?
YES - Go to step 6.
NO Faulty gearbox.l
6. Adjust the rack guide (see page 17-30) and retest.
Is the steering OK?
YES Repair is completed.l
NO Faulty gearbox. t
7. Check the feed and return lines between the pump
and the gearbox for clogging and deformation.
Are the lines clogged or deformed?
YES - Repair or replace the lines.I
NO Faulty valve body unit or pump.!
8. Check the cylinder lines for deformation (see page
1 7 - 1 1 ] , .
Are the line6 detotmed?
YES- Replace the tines. t
NO Go to step 9.
9, Check for a bent rack shaft or misadjusted rack
