pipe A.
Test conditions:

Running engine at 1,500 rpm

Blower speed control switch at ºHIº

A/C switch ON

Temperature control dial at ºMAX. COOLº

Fully open the doors

2No bubbles presentNone, insufficient or too muchRefer 3 and 4
3No temperature difference between com-
pressor inlet and outletEmpty or nearly empty

tector and repair if necessary
(2) Add refrigerant until bubbles disappear
4Considerable temperature difference be-
tween compressor inlet and outlet.Correct or too muchRefer to 5 and 6
5Immediately after air conditioning is turned
off, refrigerant clearToo much
(1) Discharge refrigerant
(2) Remove air and supply proper amount or
purified refrigerant

Immediately after air conditioning is turned
off, refrigerant foams and then becomes
clear

*: Bubbles in the sight glass with ambient temperatures higher than usual can be considered normal if cooling
is sufficient.

(5) Refrigerant does not circulate
SymptomProbable causeDiagnosisCorrective Actions

Vacuum indicated on low pres-
sure side, very low pressure indi-
cated on high pressure side

Frost or dew seen on piping be-
fore and after receiver/ drier or ex-
pansion valve
Refrigerant flow obstructed by
moisture or dirt in refrigerating sys-
tem

Refrigerant flow obstructed by
gas leaked from expansion valve
Refrigerant does not circulate
(1) Check expansion valve
(2) Clean out dirt in expansion
valve by air blowing
(3) Replace condenser
(4) Evaporate air and supply prop-
er amount of new refrigerant.
(5) For gas leakage from expan-
sion valve, replace expansion
valve
(6) Refrigerant overcharged or insufficient cooling of
condenser
SymptomProbable causeDiagnosisRemedy

Pressure too high on both low
and high pressure sides

No sir bubbles seen through the
sight glass even when the engine
rpm is lowered
Unable to develop sufficient per-
formance due to excessive use of
refrigerating system

Insufficient cooling of condenser

Excessive refrigerant in
cycle"too much refrigerant sup-
plied

Condenser cooling
insufficient"condenser fins
clogged at cooling fan(1) Clean condenser
(2) Check cooling fan with cooling
fan motor operation
(3) If (1) and (2) are in normal
state, check amount of refrigerant
and supply proper amount of re-
frigerant

AUTOMATIC TRANSAXLE FLUID
ON-VEHICLE INSPECTION
1. CHECK THE FLUID LEVEL
HINT:
Drive the vehicle so that the engine and transaxle are at normal
operating temperature.
Fluid temperature: 70 - 80 °C (158 - 176 °F)
(a) Park the vehicle on a level surface and set the parking
brake.
(b) With the engine idling and the brake pedal depressed,
shift the shift lever into all positions from P to L position,
and return to P position.
(c) take out the dipstick and wipe it clean.
(d) Put it back fully into the pipe.
(e) take it out and check that the fluid level is in the HOT posi-
tion.
If there are leaks, it is necessary to repair or replace O-rings,
FIPGs, oil seals, plugs and/or other parts.

ADJUSTMENT
1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSY
(a) Apply the parking brake and turn the ignition switch to ON.
(b) Depress the brake pedal and check that the engine starts only when the shift lever is set in N or P posi-
tion.
(c) Check that the back-up light is lit and the reverse warning buzzer sounds only when the shift lever is
set in R position.
If a failure is found, check the continuity of the park/neutral position switch.
2. ADJUST PARK/NEUTRAL POSITION SWITCH ASSY
(a) Loosen the 2 bolts of park/neutral position switch and set
the shift lever to the N position.
(b) Align the groove with neutral basic line.
(c) Hold the switch in position and tighten the 2 bolts.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
(d) After adjustment, perform the inspection described in
step 1.
