Low-Pressure Side Is Low

WARNING: This page is about a different variant/trim than selected.

CHECK REFRIGERANT LEAKS .
Check the refrigerant for leaks. Ref. to AIR CONDITIONER (EXCEPT FOR HEV)>REFRIGERANT LEAK CHECK>INSPECTION .

NOTE: When high-pressure side is less than 0.69 MPa: Go to step 2.

Are there refrigerant leaks?

Yes: Repair the refrigerant leaking points.

No: Go to 2.
FILL PROPER AMOUNT OF REFRIGERANT .
Drain all refrigerant, and refill proper amount of refrigerant.
- Recovery: Ref. to AIR CONDITIONER (EXCEPT FOR HEV)>REFRIGERANT RECOVERY PROCEDURE>PROCEDURE .
- Fill: Ref. to AIR CONDITIONER (EXCEPT FOR HEV)>REFRIGERANT CHARGING PROCEDURE>PROCEDURE .
Is refrigerant pressure within the standard value?

Yes: Refrigerant pressure is normal.

No: Go to 3.
REPLACE EXPANSION VALVE .
Replace the expansion valve. Ref. to AIR CONDITIONER (EXCEPT FOR HEV)>EXPANSION VALVE> REMOVAL .

Is refrigerant pressure within the standard value?

Yes: Refrigerant pressure is normal.

No: Inspect the compressor. Ref. to AIR CONDITIONER (DIAGNOSTICS) (EXCEPT FOR HEV)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>COLD AIR DOES NOT COME OUT EVEN WHEN THE A/C SWITCH IS PRESSED. GLASS CANNOT BE DEFOGGED (COMPRESSOR DOES NOT OPERATE (VARIABLE)) .
