1.  Install the manifold gauge set. (See MANIFOLD GAUGE SET CONNECTION.)

2.  Start the engine and warm it up.

3.  Prepare the vehicle as follows.

•  Airflow volume: MAX HI

•  A/C switch: ON

•  Air intake port: REC

•  Airflow temperature: MAX COLD

•  Airflow mode: VENT

•  Bonnet: Open

•  All the doors and the trunk: Close

•  All the windows: Close

•  Engine speed: 1,500 rpm

4.  Verify the pressure indicated on the manifold gauge and ambient temperature.

Note

•  Measure the refrigerant pressure after approx. 10 min have elapsed from engine start.

5.  Verify that there are high/low pressure value readings within the shaded areas of the figure.
