16. REPLACE COOLER EXPANSION VALVE
(a) Replace the cooler expansion valve with a new one .
eplace the cooler expansion valve with a new one because the cooler expansion valve is either stuck or
17. CHARGE SYSTEM WITH REFRIGERANT
(a) Use a refrigerant recovery unit to recover refrigerant.
(b) Evacuate the A/C system.
(c) Add an appropriate amount of refrigerant.
If refrigerant is added and the system has not been properly evacuated (insufficient vacuum time),
moisture in the air remaining in the system will freeze in the cooler expansion valve, blocking the flow on
the high pressure side. Therefore, in order to confirm the problem, recover the refrigerant and properly
evacuate the system. Add an appropriate amount of refrigerant, and check for the DTC.
18. RECHECK FOR DTC
(a) Recheck for DTCs when the following conditions are satisfied.
Vehicle Doors Fully open
