  6. CORROSION INSPECTION

  7. INSPECT REFRIGERANT AMOUNT OF AIR CONDITIONER


    1. This method uses a manifold gauge set to locate problem areas. Read the manifold gauge pressure when these conditions are established.

      Test conditions:


      • Temperature at the air inlet with the air recirculation switch set at RECIRC is 30 to 35°C (86 to 95°F).

      • Engine is running at 1500 rpm.

      • All doors are fully open.

      • Blower speed control switch is at HI.

      • A/C switch is on.

      Gauge readings (Reference):

      A01IS1KE04

      1. A01ITTAE01

        Normally functioning refrigeration system.

        Gauge Reading
        Pressure Side Refrigerant Volume
        Low

        0.15 to 0.25 MPa (1.5 to 2.5 kgf/cm2)

        High

        1.37 to 1.57 MPa (14 to 16 kgf/cm2)

      2. The A/C system periodically changes between normal and improper function due to moisture in the refrigerant system.

        A01IQ3GE16
        Symptom Probable Cause Diagnosis Corrective Action
        During operation, pressure on low pressure side cycles between normal and vacuum Moisture in refrigeration system freezes at expansion valve orifice, causing temporary stop of cycle. However, when melted, normal state is restored.
        • Dryer is overly saturated


        • Moisture in refrigeration system freezes at expansion valve orifice and blocks refrigerant circulation


        1. Replace cooler dryer

        2. Remove moisture from cycle by repeatedly evacuating air

        3. Supply appropriate volume of new refrigerant

      3. The A/C system does not function effectively due to insufficient refrigerant.

        A01INMKE09
        Symptom Probable Cause Diagnosis Corrective Action

        • Pressure low on both low and high pressure sides

        • Cooling performance insufficient

        Gas leakage from refrigeration system
        • Insufficient refrigerant

        • Refrigerant leakage


        1. Check for gas leakage and repair if necessary

        2. Supply appropriate volume of new refrigerant

        3. If indicated pressure value close to 0 when connected to gauge, create vacuum after inspecting and repairing location of leakage

      4. The A/C system does not function effectively due to poor circulation of the refrigerant.

        A01ITG7E10
        Symptom Probable Cause Diagnosis Corrective Action

        • Pressure low on both low and high pressure sides

        • Frost exists on piping from condenser to A/C unit

      5. The A/C system does not function or functions intermittently because the refrigerant does not circulate.

        A01IQFKE09
        Symptom Probable Cause Diagnosis Corrective Action

        • Vacuum indicated on low pressure side, and extremely low pressure indicated on high pressure side

        • Frost or condensation seen on piping on both sides of condenser or expansion valve


        • Refrigerant flow obstructed by moisture or dirt in refrigeration system

        • Refrigerant flow obstructed by gas leakage from expansion valve

        Refrigerant does not circulate
        1. Check expansion valve refrigerant

        2. Clean expansion valve using compressed air

        3. Replace condenser

        4. Evacuate air and charge appropriate volume of new refrigerant

        5. For gas leakage from expansion valve, replace expansion valve

      6. The A/C system does not function effectively due to overcharged refrigerant or insufficient cooling of the condenser.

        1. Clean condenser

        2. Check condenser fan motor operation

        3. If actions taken in 1 and 2 do not solve problem, check amount of refrigerant and adjust amount of refrigerant to appropriate amount

      7. The A/C system does not function due to air in the refrigeration system.

        CAUTION:

        The low-pressure piping may be very hot and cause serious burns.
