GEARSHIFT OR SELECTOR LEVER (TRANSMISSION)
Check gear shift or selector lever for smooth shifting to all positions and for good performance of transmission in
any position.
With automatic transmission equipped vehicle, also check that shift indicator indicates properly according to
which position selector lever is shifted to.
With automatic transmission equipped vehicle, make sure that vehicle is at complete stop when shifting selector
lever to “P” range position and release all brakes.
BRAKE
Foot Brake
Check the following:
that brake pedal has proper travel,
that brake works properly,
that it is free from noise,
that braking force is applied equally on all wheels,
and that brake do not drag.
Parking Brake
Check that lever has proper travel.
Check to ensure that parking brake is fully effective when the vehicle is stopped on the safe slope and brake
lever is pulled all the way.
STEERING
Check to ensure that steering wheel is free from instability, or abnormally heavy feeling.
Check that the vehicle does not wander or pull to one side.
ENGINE
Check that engine responds readily at all speeds.
Check that engine is free from abnormal noise and abnormal vibration.
BODY, WHEELS AND POWER TRANSMITTING SYSTEM
Check that body, wheels and power transmitting system are free from abnormal noise and abnormal vibration or
any other abnormal condition.
METERS AND GAUGE
Check that speedometer, odometer, fuel meter, temperature gauge, etc. are operating accurately.
LIGHTS
Check that all lights operate properly.
WINDSHIELD DEFROSTER
Periodically check that air comes out from defroster outlet when operating heater or air conditioning.
Set mode control lever to defroster position and fan switch lever to “HI” position for this check. WARNING:
With vehicle parked on a fairly steep slope, make sure nothing is in the way downhill to avoid any per-
sonal injury or property damage. Be prepared to apply regular brake quickly even if vehicle should
start to move.

Abnormal noise from crankshaft pulley
Abnormal noise from tension pulley
Abnormal noise from A/C evaporator
Abnormal noise from blower fan motor
Condition Possible Cause Correction
A large rattling noise
is heard at idle or sud-
den acceleration.Loosen crankshaft pulley bolt. Retighten bolt.
Condition Possible Cause Correction
Clattering noise is
heard from pulley.Worn or damaged bearing. Replace tension pulley.
Pulley cranks upon
contact.Cracked or loose bracket. Replace or retighten bracket.
Condition Possible Cause Correction
Whistling sound is
heard from A/C evapo-
rator.Depending on the combination of the interior /
exterior temperatures, engine rpm and refriger-
ant pressure, the refrigerant flowing out of the
expansion valve may, under certain conditions,
make a whistling sound.At times, slightly decreasing refrig-
erant volume may stop this noise.
Inspect expansion valve and
replace if faulty.
Condition Possible Cause Correction
Blower fan motor

Performance Diagnosis
1) Confirm that vehicle and environmental conditions are as fol-
lows.
Vehicle is not exposed to direct sun.
Ambient temperature is within 15 – 35 °C (59 – 95 °F).
2) Make sure that high pressure valve (1) and low pressure
valve (2) of manifold gauge set (3) are firmly closed.
3) Connect high pressure charging hose (4) to high pressure
service valve (5), and connect low pressure charging hose
(6) to low pressure service valve (7).
4) Bleed the air in charging hoses (4), (6) by loosening their
respective nuts on manifold gauge set (3), utilizing the refrig-
erant pressure. When a hissing sound is heard, immediately
tighten nut.
5) Warm up engine to normal operating temperature (engine
coolant temperature at 80 – 90 °C (176 – 194 °F)) and keep
it at specified idle speed. (Radiator cooling fan should not be
working when checking pressure and temperature.)
6) Turn A/C switch ON, and set blower switch at “HI” (3rd posi-
tion), temperature knob at “COOL” air outlet control knob at
“FACE” and fresh / circulation control knob at “CIRCULA-
TION”. (Confirm that A/C compressor and radiator / con-
denser cooling fan are working.)
Keep all windows, doors and engine food open.
Performance diagnosis condition
7) With dry bulb thermometer (1) inserted into center duct air
outlet and another one set near evaporator air inlet, read
temperature indicated on each thermometer. CAUTION:
Do not interchange high and low pressure charging
hoses by mistake.
Ambient temperature 15 – 35 °C (59 – 95 °F)
Engine rpm Keep to 1,500 rpm.

2) Connect Low charging hose (1) and High charging hose (2)
of the manifold gauge set (3) in position. Thus open refriger-
ant container valve (4) to purge the charging line.
3) Open the high pressure side valve (5) and charge refrigerant
to system.
4) After a while, open the low pressure side valve (6) and close
the high pressure side valve (5).
5) Start engine and keep engine speed at 1500 r/min. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container should be held upright.
7) When refrigerant container (3) is emptied, use the following
procedure to replace refrigerant container with a new refrig-
erant container (3).
a) Close low pressure valve.
b) Replace empty container (3) with a refrigerant container
which has been charged with refrigerant. When using
refrigerant container tap valve (4), use the following proce-
dure for replacement.
i) Retract needle (1) and remove refrigerant container tap
valve (4) by loosening its plate nut (2).
ii) Install previously-removed refrigerant container tap valve
(4) to a new refrigerant container (3).
c) Purge any air existing in center charging hose
When using refrigerant container tap valve, use the follow-
ing procedure to purge air.
i) Once fully tighten refrigerant container tap valve (1), and
then loosen (open) plate nut (2) slightly.
ii) Open low pressure side valve (3) of manifold gauge set
(4) a little.
iii) As soon as refrigerant comes out with a “hiss” through a
clearance between refrigerant container and tap valve,
tighten plate nut (2) as well as low pressure side valve (3).
iv) Turn handle of tap valve (1) clockwise so that its needle is
screwed into the new container to make a hole for refriger-
ant flow. WARNING:
Make sure that high pressure side valve is closed
securely.

Tire Diagnosis
Irregular and/or Premature Wear
Irregular and premature wear has many possible causes. Some
of them are: incorrect inflation pressures lack of tire rotation, driv-
ing habits, improper alignment.
If the following conditions are noted rotation is in order:
Front tire wear is different from rear.
Uneven wear exists across the tread of any tire.
Left front and right front tire wear is unequal.
Left rear and right rear tire wear is unequal.
There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
Left front and right front tire wear is unequal.
Wear is uneven across the tread of any front tire.
Front tire treads have scuffed appearance with “feather”
edges on one side of tread ribs or blocks.
Wear Indicators
The original equipment tires have built-in tread wear indicators to
show when tires need replacement. These indicators will appear
as 12 mm (0.47 inch) wide bands when the tire tread depth
becomes 1.6 mm (0.063 inch). When the indicators appear in 3 or
more grooves at 6 locations, tire replacement is recommended.
Radial Tire Waddle
Waddle is side to side movement at the front and/or rear of the
vehicle. It is caused by the steel belt not being straight within the
tire. It is most noticeable at low speed, 5 to 30 mph. It is possible
to road test a vehicle and tell on which end of the vehicle the
faulty tire is located. If the waddle tire is on the rear, the rear end
of the vehicle will shake from side to side or “waddle”. From the
driver’s seat it feels as though someone is pushing on the side of
the vehicle. If the faulty tire is on the front, the waddle is more
visual. The front sheet metal appears to be moving back and forth
and the driver feels as though he is at the pivot point in the vehi-
cle. Waddle can be quickly diagnosed by using a Tire Problem
Detector (TPD) and following the equipment manufacturer’s rec-
ommendations.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehi-
cle can be used as follows:
[A] : Hard cornering, under inflation or lack of tire rotation
[B] : Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration
