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 (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 (HEV)>REFRIGERANT RECOVERY PROCEDURE>PROCEDURE .
- Fill: Ref. to AIR CONDITIONER (HEV)>REFRIGERANT CHARGING PROCEDURE>PROCEDURE .
Is refrigerant pressure within the standard value?

Yes : Refrigerant pressure is normal.

No : Go to 3.
REPLACE THE EXPANSION VALVE - COOLER ASSEMBLY .
Replace the expansion valve - cooler assembly. Ref. to AIR CONDITIONER (HEV)>EXPANSION VALVE>REMOVAL>COOLER VALVE .

Is refrigerant pressure within the standard value?

Yes : Refrigerant pressure is normal.

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