1. Normally Functioning Refrigeration System

On-Vehicle Inspection
This is a method in which the trouble is located by using a gauge set. Read the gauge pressure when these conditions are established.

Test Conditions
Temperature at the air inlet with the switch set at RECIRC is 3O - 35 °C (86 ~ 95 °F)
- Engine running at 1,5OO rpm
- Blower speed control knob on "4" position
- Temperature control knob on "COOL" position

Note: It should be noted that the gauge indications may vary slightly due to ambient temperature conditions






1. Normally functioning refrigeration system.
Gauge reading:
Low pressure side
O.15 - O.25 MPa (21.8 - 36.3 psi, 1.5 - 2.5 kgf/cm sqared)

High pressure side
1.37 - 1.57 MPa (199 - 228 psi, 14 - 16 kgf/cm sqared)
