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)
Relief pressuretoo low
Faulty valve body unit
Abnormal
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).

Parking Brake Switch Test
1. Remove the parking brake cover,
2. Disconnect the connector from the parking brakeswitch.
3. Check for continuity between the terminal and bodyground in each position according to the table.

NOTE (Canada): lf the parking brake switch is OK, butthe brake system indicator does not function, perform
the input test for the daytime running lights control unit(see section 23).
Brake Fluid Level Switch Test
1. Remove the reservoir cap. Check that the float
moves up and down freely; if it doesn't, replace the
reservoir cap assembly.
2. Check for continuity between the terminals in each
switch position according to the table.
