Air Conditioning Diagnosis
For the execution of the charging and discharging operation in the table above, refer to Recovery, Recycling, Evacuating and Charging.

Checking The Refrigerant System With Manifold Gauge
Since Refrigerant-134a (HFC-134a) is used in the air conditioning system in this vehicle, be sure to use manifold gauges, charging hoses and other air conditioning service tools for HFC-134a when checking the refrigerant system.

Conditions:
- Run the engine at idling
- Air conditioning switch is "ON"
- Run the blower motor at "HIGH" position
- Temperature control lever set to "MAX COLD"
- Air source selector lever at "CIRC"
- Open the engine hood
- Close all the doors

Normal Pressure:
- At ambient temperature: approx. 25 - 30 °C (77 - 86 °F).
- At low-pressure side: approx. 147.1 - 294.2 kPa (21.3 - 42.7 psi).




- At high-pressure side: approx. 1372.9 - 1863.3 kPa (199.1 - 270.2 psi). Refer to the table on the refrigerant pressure-temperature relationship.
