2. Performance Test Diagnosis
If various conditions caused to other air conditioning system, the characteristics revealed on manifold gauge
reading are shown in the following:
As to the method of a performance test, refer to the item of ªPerformance Testº.
Each shaded area on the following tables indicates a reading of the normal system when the temperature
of outside air is 32.5ÉC (91ÉF).
Condition Probable cause Corrective action
INSUFFICIENT REFRIGERANT CHARGE

Insufficient cooling Refrigerant is small, or
leaking a little.(1) Perform leak test.
(2) Repair leak.
(3) Charge system.
Evacuate, as
necessary, and
recharge system.
ALMOST NO REFRIGERANT
G4M0674
No cooling action Serious refrigerant leak.Stop compressor
immediately.
(1) Perform leak test.
(2) Discharge system.
(3) Repair leak(s).
(4) Replace receiver
drier if necessary.
(5) Check oil level.
(6) Evacuate and
recharge system.

Slight cooling;
Sweating or frosted
expansion valve inlet.Expansion valve
restricts refrigerant flow.
IExpansion valve is
clogged.
IExpansion valve is

IValve stuck closed.
IThermal bulb has lost
charge.If valve inlet reveals
sweat or frost:
(1) Discharge system
(2) Remove valve and
