Steering Force Check

1) Place vehicle on level road and set steering wheel at
straight-ahead position.
2) Check that tire inflation pressure is as specified.
(Refer to tire placard.)
3) Start engine and keep it running till power steering
fluid is warmed to 50 to 60 °C (122 to 140 °F).
4) With engine idling, measure steering force by pulling
spring balancer hooked on steering wheel in
tangential direction.

Steering Wheel Recovery Check

WARNING
!
When performing a check, select a place
where there is no traffic or possibility of a
traffic accident and be very careful during
testing to avoid occurrence of an accident.
Check steering wheel for recovery as follows.
1) Rotate it to either right or left end.
2) Keep it at the end, and start the vehicle slowly.
3) Accelerate vehicle slowly.
If steering wheel begins to return at the vehicle speed
less than 10 km/h (6.3 mph), it is normal condition.
If the check result is abnormal, diagnose the fault part
referring to "Poor recovery from turns" in "P/S System
Symptom Diagnosis: ".

Idle Up System Check

S5JB0A6304003
1) Warm up engine to normal operating temperature.
2) Turn A/C switch OFF, if equipped.
3) Turn steering wheel fully and check idle speed.
Engine idle speed drops a little momentarily when
steering wheel is turned fully but returns to its
specified level immediately.
If power steering pressure switch connector is
connected, check the same with that connector
disconnected.
Momentary drop of engine idle speed should be less
when it is connected than when disconnected.

Hydraulic Pressure in P/S Circuit Check

1) After cleaning joint of high pressure hose and P/S
pump thoroughly, disconnect hose from pump and
install special tool (oil pressure gauge, attachment
I5JB0A630005-01
and hose).
CAUTION
!
Take care not to cause damage to A/C
condenser during service operation, if
equipped.
