Inspect Refrigerant Pressure

Note

• Perform the procedure with the manifold gauge connected. (See MANIFOLD GAUGE SET CONNECTION)

• Start the engine and operate at an engine speed of 1,500 rpm.

• Perform the procedure while the vehicle is not exposed to direct sunlight.

1.Prepare the vehicle as follows.

― A/C switch: ON

― Air intake mode: REC

― Airflow mode: Vent

― Airflow temperature setting: MAX COLD

― Airflow volume setting: Maximum

― Hood: Open

― All doors and liftgate: Closed

― All door glass: Fully closed

― Active air shutter (with active air shutter): Open

2.Wait for 8 min after the engine is started.

3.Record the pressure indicated on the manifold gauge and ambient temperature for 2 min.

4.Verify that the refrigerant pressure on the high pressure side and low pressure side is within the range of the shaded area shown in the figure.
