  1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET HINT: This is a method where a manifold gauge set is used to help locate the problem. Read the manifold gauge pressure when the following conditions are established. Test conditions: Temperature at the air inlet with the switch set at RECIRC is 30 to 35°C (86 to 95°F). Engine is running at 1500 RPM. Blower speed control switch is at "HI". Temperature control dial is at "COOL". A/C switch is ON. Doors are fully open. Normally functioning refrigeration system GAUGE READING Pressure Side Refrigerant Volume Low 0.15 to 0.25 MPa (1.5 to 2.5 kgf/cm 2 , 21 to 36 psi) High 1.37 to 1.57 MPa (13.9 to 16.0 kgf/cm 2 , 198 to 227 psi) Moisture is present in refrigeration system. Symptom Probable Cause Diagnosis Corrective Action During operation, pressure on low pressure side cycles between normal and vacuum Moisture in the A/C system will freeze at the expansion valve orifice, causing the refrigeration cycle to temporarily stop After the system stops, and warms up again, the ice will melt and normal operation will be temporarily restored Cooler dryer (integrated into the condenser tank) in oversaturated state Moisture in the refrigeration system freezes at the expansion valve orifice and blocks circulation of refrigerant Replace the cooler dryer Remove moisture in the system by repeatedly evacuating air Supply a proper amount of new refrigerant Insufficient cooling Symptom Probable Cause Diagnosis Corrective Action Pressure is low on both low and high pressure sides Insufficient cooling performance Gas leakage from the refrigeration system Insufficient refrigerant Refrigerant leaking Check for gas leaks and repair if necessary Supply a proper amount of new refrigerant If the gauge indicates a pressure of close to 0, then it will be necessary to evacuate the system after repairing the leak Poor circulation of refrigerant Symptom Probable Cause Diagnosis Corrective Action Pressure is low on both low and high pressure sides Frost exists on pipe from condenser to unit Refrigerant flow is obstructed by dirt inside the pipes of the condenser core Receiver is clogged Replace the condenser Refrigerant does not circulate. Symptom Probable Cause Diagnosis Corrective Action Vacuum is indicated on low pressure side and very low pressure is indicated on high pressure side Frost or condensation is seen on piping on both sides of receiver/drier or expansion valve Refrigerant flow is obstructed by moisture or dirt in the refrigeration system Refrigerant flow is obstructed by gas leaking internally through the expansion valve Refrigerant does not circulate Check the expansion valve Replace the expansion valve Replace the condenser Evacuate air and supply a proper amount of new refrigerant For internal gas leak at the expansion valve, replace the expansion valve Refrigerant is overcharged or cooling effectiveness of the condenser is insufficient. Symptom Probable Cause Diagnosis Corrective Action Pressure is too high on both low and high pressure sides Unable to develop sufficient performance due to an excessive use of refrigeration system Cooling effectiveness of the condenser is insufficient Excessive refrigerant in cycle --> excessive refrigerant was added during recharging Condenser cooling effectiveness is insufficient --> condenser fins are clogged at the cooling fan Clean the condenser Check the operation of the condenser cooling fan If 1 and 2 are normal state, check the amount of refrigerant and supply the proper amount of refrigerant Air is present in the refrigeration system. Symptom Probable Cause Diagnosis Corrective Action Pressure is too high on both low and high pressure sides The low pressure piping is too hot to touch Air in the system Air present in the refrigeration system Insufficient vacuum purging Check compressor oil to see if it is dirty or insufficient Evacuate the system and recharge it with new or purified refrigerant Expansion valve malfunction Symptom Probable Cause Diagnosis Corrective Action Pressure is too high on both low and high pressure sides Frost or a large amount of condensation on piping on low pressure side Expansion valve may be sticking Excessive refrigerant in low pressure piping Expansion valve opened too wide Check expansion valve Insufficient compressor compression Symptom Probable Cause Diagnosis Corrective Action Pressure is too high both on low and high pressure sides Pressure is too low on high pressure side Internal leak in the compressor Low compression Leak from a damaged valve, or parts may be broken Replace the compressor Gauge readings (Reference)

  1. RECOVER REFRIGERANT FROM REFRIGERATION SYSTEM Start up the engine. Turn the A/C switch on. Operate the cooler compressor at an engine speed of approximately 1000 RPM for 5 to 6 minutes to circulate the refrigerant. This causes most of the compressor oil from the various components of the A/C system to collect in the A/C compressor. Stop the engine. Recover the refrigerant from the A/C system using a refrigerant recovery unit.
  2. CHARGE WITH REFRIGERANT Perform vacuum purging using a vacuum pump. Charge with refrigerant HFC-134a (R134a). Standard 410 to 470 g (14.5 to 16.6 oz.) SST: 09985-20010 09985-02010 09985-02050 09985-02060 09985-02070 09985-02080 09985-02090 09985-02110 09985-02130 09985-02140 09985-02150 NOTE: Do not turn the A/C on before charging with refrigerant. Doing so will cause the cooler compressor to work without refrigerant, resulting in overheating of the cooler compressor. HINT: Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units are not always able to recover 100% of the refrigerant from an A/C system.
  3. WARM UP ENGINE Keep the A/C switch on for at least 2 minutes to warm up the compressor. NOTE: Be sure to warm up the compressor when turning the A/C on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.
  4. INSPECT FOR REFRIGERANT LEAK After recharging with refrigerant, inspect for refrigerant leaks using a halogen leak detector. Carry out the test under the following conditions: Turn the ignition switch off. Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as evaporated gasoline and exhaust gas). Repeat the test 2 or 3 times. Make sure that there is some refrigerant remaining in the refrigeration system. When the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm 2 , 57 to 85 psi) Using a halogen leak detector, inspect for refrigerant leaks from the refrigerant lines. Bring the halogen leak detector close to the drain hose with the detector's power off, and then turn the detector on. HINT: After the blower motor has stopped, let the cooling unit stand for more than 15 minutes. Bring the halogen leak detector sensor under the drain hose. When bringing the halogen leak detector close to the drain hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow testing. If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test. Disconnect the pressure switch connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
