Troubleshooting
General Troubleshootin g
Check the following before you begin:
. Has the suspension been modified in a way that would affect steering?
. Are tire sizes, tire variety and air pressure correct?
. ls the steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adjusted?
. ls steering fluid reservoir filled to proper level?
. ls the engine idle speed correct and steady?
Hard Steering (Check the power assist, see page 17-12. lf the force is over 29 N (3.0 kgl 6.6 lbfl, proceed with this troubleshooting.i
Abnormalthiidpressure (Iluidpressure is toohigh)

Check the teed and return circuit lines and hosebetween the gearbox and pump for clogging anddeformation.
Normal line and hose
Check the pump fluid pressure(see page 17-16 or 17-17).Measure steady state lluid pres-
sure at idle with the pressure con-trol valve and the shut-off valve (it
so equipped) fully open.The fluid pressure should be 1,500kPa (15 kgf/cm,,213 psi)or less.
Normal
Check the flow control valve (see page 17 26).. Check the valv€ lor smooth movement in the hous-ing.. Check the relief valve for leaks.
Check the pump fluid pressure(see page 17-16 or l7-17).Measure pump relief pressure atidle with the pressure controlvalve and the shut'off valve lil soequipped) fully closed.The fluid pressure should be 6,9007,800 kPa (70 - 80 kgflcm,, 1,000- 1,140 psi).

Troubleshooting
Noise and Vibration
NOTE: Pump noise in first 2 - 3 minutes after starting in cold weather is normal.
Humming
Rattle or chattering
Humming due to pulsation of fluid is normal, particularly when the wheel isturned with the vehicle stooDed.
lf equipped with automatic trans-mission, the hum could be thetorque converter or pump noase.
Confirm by temporarily removingthe pump belt.
Feed hose (high-pressure) touch-ing the frame.Beposition the feed hose.
Loose steering shaft connector,tie-rod, or balljoint.Check and tighten, or replaceparts as necessary,
Column shaft wobbling.Roplace the column assembly.
Check the rack guide for properadjustment (see page 17-15).Adjust, if necessary.
Rattling sound and feeling when turning the steering wheel right and left with th€engine OFF is normal.
Pump noise, though not loud, from the valve body unit can be heard when turn-ing the steering wheel to full lock in either direction. This is normal. Do not holdthe steering wheel at full lock lor more than five seconds when inspecting.

lnspection and Adjustment
Pump Pressure Gheck With T/N 07406 - 0010001
Check the fluid pressure as follows to determine whetherthe trouble is in the pump orgearbox.
1. Check the powsr steering fluid level (see page 17-15), and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the pow€r steeringiluid on the frame and other pans. thon install theP/S joint adapter (pumpl on the pump outlet.

6. Fully open the pressure controlvatve.
7. Start the engine and let it idle.
8. Turn the steering wheel from lock-to-lock severaltimes to warm the fluid to operating temperature.
9, Measure steady-state fluid pressure while the engineis idling. lf the pump is in good condition, the gauge
should read less than 1,500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet hose or valve bodvunit (see General Troubleshooting).
10. Close the pressure control valve, then close theshut-off valve gradually until the pressure gauge
nsedle is stable. Read the pressure.

11. lmmodiately open the pressure controlvalve fullv.
lf the pump is in good condition, the gauge shouldread at least 6,900 - 7,800 kpa (70 - 80 kgflcmr,'1,000 - 1.140 psi). A low reading means pump out-put is too low for full assist. Repair or replace theDUMD.

Pump Pressure Check With T/N 07406 -
Check the fluid pressure as follows to determine whether
the trouble is in the pump or gearbox.
1. Check the power steering tluid level (see page 17-
151, and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the power steering
fluid on the frame and other parts, then install the
P/S joint adapter (pump) on the pump outlet.

Close the-pressure control valve gradually and read
the oressure.
CAUTION: Do not keep the pressurs control valve
closed more then 5 seconds or the pump could bo
damaged by overheating.
lmmediately open the pressure controlvalve fully.
lf the pump is in good condition, the gauge should
read at least 6,900 - 7;800 kPa (70 - 80 kgflcm',
1,000 - 1.140 psi), A low reading means pump out-
Dut is too low for {ull assist. Repair or replace the
