HVAC SYSTEM (HEATER, VENTILATOR AND A/C) > Refrigerant Pressure with Manifold Gauge Set

PROCEDURE

1. REFRIGERANT GAS PRESSURE INSPECTION

1. Prepare the vehicle.

NOTE:

Check that the ambient temperature is 25 — 40°C (77 — 104°F) and that the humidity is 30% — 80%.

• Place the vehicle in the shade and windless condition, and open the front hood.

• Open the front windows and close all doors.

2. Check the refrigerant pressure.

Preparation tool:

Manifold gauge set

(1) Connect the manifold gauge set, and start the engine.

(2) Set the vehicle to the following conditions.

Item	Condition
Engine	Warmed up (Engine coolant temperature indicator light: OFF)
Air vent grille	Shutter is fully open.
A/C switch	ON
Temperature adjustment dial	LO (MAX COOL)
FRESH/RECIRC switch	RECIRC
Air flow control dial or switch	VENT
Fan dial	Auto A/C model: 5/7 level
Fan dial	Manual A/C model: 3/4 level

(3) In the condition of step (2), idle the engine for 30 minutes.

(4) Read the gauge values on both high pressure side and low pressure side for manifold gauge.

3. Measure the air vent grille outlet opening temperature, ambient temperature and humidity.

Preparation tool:

Thermometer and hygrometer

NOTE:

For outlet opening temperature, measure the average temperature of center grille assembly and side grille assembly.

4. Check that the high and low pressures and outlet opening temperature for ambient temperature and humidity is within the standard value described in the chart below.

5. Refer to “DIAGNOSIS WITH SYMPTOM” if the inspection result is not within the standard value. Refrigerant Pressure with Manifold Gauge Set > INSPECTION">
