CNSPECTION AN&I ”ADJUSTMENT
For models equipped with the auto-cruise control systemreferto
P.14-136.(1) Turn air conditioner and lights OFF.
Inspect and adjust at no load.
2) Warm engine until stabilized at idle.
3) Confirm idle speed is at prescribed rpm.
4) Stop engine (ignition switch OFF).
5) Confirm there are no sharp bends in accelerator cable.
6) Check inner cable for correct slack.
7) If there is too much slack or no slack, adjust play by the
following procedures.
@ On models with an SOHC engine, turn the ignition
switch to the ON position (without starting the engine)
and leave in that condition for approximately 15
seconds.@
Loosen the adjusting bolts on the air intake plenum, andthen secure the outer cable so that the free play of the
inner cable will be the standard value.
Standard value:
jlr
<M/T>l-2 mm (.04-.08 in.) \. *
<A/T>3-5 mm (.12-.20 in.)
NOTEIf there is excessive play of the accelerator cable, the
vehicle speed drop (“undershoot”) when climbing a slope
will be large.
If there is no play (excessive tension) of the accelerator
cable, the idling speed will increase.
(8) After adjusting, confirm that throttle valve fully opens and
closes by operating pedal.
(9) Adjust accelerator cable play and confirm throttle lever
stopper touches the idle switch.
ACCELERATOR SWITCH INSPECTION AND
ADJUSTMENT
NlWlEB(1) After warming up the engine, check to be sure that the
accelerator switch is ON when the accelerator pedal’ is in
the free condition. If there is a malfunction, adjust by using
the adjusting bolt.
(2) Press the accelerator pedal by hand until the accelerator
switch switches from ON to OFF and confirm that the
amount of pedal movement (A in the figure) is within the
standard value range.
Standard value:
Accelerator switch switching point
2-6 mm
(.08-.24 ‘in.)
(3) If the distance (A in the figure) is not within the standard
value, adjust it by using the adjusting bolt.

SERVICE ADJUSTMENT PROCEDURES
<POWER STEERING>
STEERING WHEEL FREE PLAY CHECKNlSFABH
1. With engine running (hydraulic operation), set front wheels
straight ahead.2. Measure the play on steering wheel circumference before
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2
in.13. When the play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4.If the free play still exceeds the limit value set steering wheel
straight ahead with engine stopped. Load 5
N (1 lb.1 towardssteering wheel circumference and check play.
Standard value (steering wheel play with engine
stopped): 11 mm
I.43 in.)
If the play exceeds the standard value, remove steering gearbox and check total pinion torque.
STEERING ANGLE CHECKN19FDBJ1. Set front wheels on turning radius gauge and measure
steering angle.Standard values:
Turbo <A/T>
Inner wheel
31”30’+2”Outer wheel
27”OOOther models
Inner wheel
35”00’_+2”Outer wheel
2990’
2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 2-Service Adjustment
Procedures) and recheck.TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)N19FVA8The inspection procedure for the tie rod end ball joint variation
is the same as for the manual steering system. (Refer to
P. 19-7.)
TIE ROD END BALL JOINT STARTING TORQUE
CHECKNlSFEBDThe inspection procedure for the tie rod end ball joint starting
torque is the same as for the manual steering system. (Refer to

24-18 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures
(5) Screw a can of R-12 to the opened manifold valve. Be sure
gasket is in place and in good condition. Tighten refrigerantcan and manifold locking nut to insure a good seal. Do not
overtighten 8 to
11 Nm (6 to 8 ft.lbs.) is sufficient if gasket
is in good condition.
(6) Turn manifold valve (above the refrigerant can) completely
clockwise to puncture the can. This closes the valve and
seals the refrigerant in the can.
Caution
Never heat small cans of refrigerant over
40°C (104°F)as they may explode.
(7) Place the refrigerant in a large pan of water heated to 52°C
(104°F). Place pan of water containing the refrigerant can
on an accurate scale so the amount of refrigerant added
can be weighed. Open the refrigerant manifold valve.
(8) Purge all air from test hoses. Air in the system will be
trapped in the condenser causing abnormally high dis-
charge pressures and interfering with condensing of the
refrigerant.(9) Slightly loosen both test hoses at the gauge set manifold.
Tighten the hoses as soon as the air is purged.
(10)Slightly loosen charging hose connection at gauge set
manifold. This will purge air from the charging hose.
Tighten connection as soon as air is purged.
(I l)With vehicle windows open and hood up, operate engine at1,500 rpm and jump the low pressure switch terminals
located on the receiver drier so the clutch will remain
engaged.
(12)Place air conditioner control on air conditioner and place theblower switch on high.
(13)lf necessary, block the condenser to maintain a discharge
pressure of 1,422 to 1,520
kPa (206 to 220 psi). System
must be charged through the evaporator suction service
ports as follows:
(a) Slowly open the suction service gauge valve.
Meter flow of refrigerant by adjusting, the suciton
service gauge valve so that pressure registered at the
suction service gauge does not exceed 345 kPa (50 psi).Keep refrigerant container upright.
(b) Add refrigerant gas until there is no foam visible at the
sight glass.
Add an additional
170 g (6 oz.)
(c) Close the suction gauge valve.
CautionToo much refrigerant in the system can cause
abnormally high discharge pressures. Care must beused so that the exact recommended amount or
refrigerant is added after foam clears in the sight
glass.(d) Close dispensing manifold valve. Remove test hoses
and adapters from the service ports of compressor,
install protective caps at service ports and reconnect
wiring.(e) Check system performance.

IDLE-UP OPERATION CHECKN24FoAA
(I) Before inspection and adjustment set vehicle in the
following condition:
l Engine coolant temperature:
80-90°C (176-194°F)
lLights, electric cooling fan and accessories: Set to OFFl Transaxle: Neutral
(N or P for vehicles with A/T)l Steering wheel: Straightforward
(2) Check whether or not the idling speed is the standard
value.Standard value:
4.8L Engine>700 rpm
<2.0L DOHC Engine>750 rpm
NOTE
There is no necessity to make an adjustment, because theidling speed is automatically adjusted by the
ISC” system.
If, however, there occurs a deviation from the standard
value for some reason, check the
ISC” system.
(3) Check to be sure that the idlig speed becomes the standardvalue when the air conditioner switch is switched ON and
the air conditioner is activated.
Standard value: 850 rpm
NOTE
There is no necessity to make an adjustment, because theidling speed is automatically adjusted by the

If, however, there occurs a deviation from the standard
value for some reason, check the
