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?
• 15 the steering wheel original equipment or equivalent?
• 15 the power steering pump belt properly adjusted?
• Is steering fluid reservoir filled to proper level?
• Is the engine idle speed correct and steady?
Hard Steering (Check the power assist. see page 17-12. If the force is over 29 N (3.0 kgf, 6.6 Ibf), proceed with this troubleshooting.)

Check the pump fluid pressure
(see page 17-16 or 17-17).
Measure steady-state fluid pres-
sure at idle with the pressure con-
trol valve and the shut-off valve
(if
so equipped) fully open.
The fluid pressure should be 1,500
kPa (15 kgf/cm
2 ,
213 psi) or less.
Normal
Check the pump fluid pressure
(see page 17-16 or 17-17).
Measure pump relief pressure at
idle with the pressure control
valve and the shut-off valve (if so
equipped) fully closed.
The fluid pressure should be 6,900
- 7,800 kPa (70 - 80 kgf/cm2, 1,000
-1,140 psi).
