8. Connect airbag module connector.
9. Install alllids.
10. Conduct self-diagnosis toensure entireSRSoperates prop-
erly. (Use CONSULT orwarning lampcheck.)
Before performing self-diagnosis, connectbothbattery
cables.
11. Turn steering wheeltothe leftend andthen tothe right end
fully tomake surethatspiral cableisset inthe neutral
position.
If air bag warning lampblinks orstays ON(atthe user
mode), itshows thespiral cablemaybesnapped duetoits
improper position.Performself-diagnosis again(useCON-
SUL Tor warning lamp).Ifa malfunction isdetected, replace
the spiral cablewithanew one.

Bleeding Hydraulic System

1. Raise frontendofvehicle untilwheels areclear ofthe
ground.
2. Add fluid intooiltank tospecified level.Thenquickly turn
steering wheelfullytoright andleftand lightly touchsteer-
ing stoppers.
Repeat steering wheeloperation untilfluid level nolonger
decreases.
3. Start engine.
Repeat step2.above.
• Incomplete airbleeding willcause thefollowing tooccur.
When thishappens, bleedairagain.
a. Air bubbles inreservoir tank
b. Clicking noiseinoil pump
c. Excessive buzzinginoil pump
Fluid noise mayoccur inthe valve oroil pump. Thisiscommon
when thevehicle isstationary orwhile turning thesteering
wheel slowly. Thisdoes notaffect theperformance ordurabil-
ity ofthe system.

Checking SteeringWheelTurning Force(For
power steering)

1. Park vehicle onalevel, drysurface andsetparking brake.
2. Start engine.
3. Bring power steering fluiduptoadequate operating temper-
ature. [Make suretemperature offluid isapproximately 60
to 80°C (140to176°F).]

Tires needtobe inflated tonormal pressure.

4. Check steering wheelturning forcewhen steering wheel
has been turned 360°from theneutral position.

Steering wheelturning force: •
39 N(4 kg, 9Ib) orless

5.
If
steering wheelturning forceisout ofspecification, check
rack sliding force.
a. Disconnect steeringcolumnlowerjointandknuckle arms
from thegear.
b. Start andrunengine atidle tomake suresteering fluidhas
reached normaloperating temperature.
c. Pull tie-rod slowlytomove itfrom neutral position to

Checking Hydraulic System

Before starting, checkbelttension, drivingpulleyandtirepres-
sure. 1. Set Tool. Open shut-off valve.Thenbleed air.(See "Bleed-
ing Hydraulic System"ST-7.)
2. Run engine.

Make suretemperature offluid intank rises to60 to80°C (140
to 176°F).
WARNING:
Warm upengine withshut-off valvefullyopened. Ifengine is
started withshut-off valveclosed, fluidpressure inoil pump
increases tomaximum. Thiswillraise oiltemperature abnor-
mally.

3. Check pressure withsteering wheelfullyturned toleft and
right positions withengine idlingat1,000 rpm.

CAUTION:
Do not hold thesteering wheelinalocked position formore
than 15seconds.
Oil pump maximum standardpressure:
7,649 -8,238 kPa(76.5 .82.4 bar,
78 -84 kg/cm
2,
1,109-1,194 psi)

4.
If
oil pressure isbelow thestandard pressure, slowlyclose
shut-off valveandcheck pressure.
• When pressure reachesstandard pressure, gearisdam-
aged.
• When pressure remainsbelowstandard pressure, pumpis
damaged.

CAUTION: Do not close shut-off valveformore than15seconds.

5.
If
oil pressure ishigher thanstandard pressure, checkoil

6. After checking hydraulic system,removeToolandaddfluid
