Low Temperature Protection Control
• When thermo control amp. detects
that evaporator fin temperature
is 1.5° C (35° F) or less, thermo control amp. switches A/C ON sig-
nal to OFF and stops the compressor.
When the evaporator fin temperature returns to 3 °C (37° F) or
more, the compressor is activated.
CONTROL BY ECM
Refrigerant Pressure Protection
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure s\
en-
sor, located on the liquid tank on the condenser. The refr igerant pressure sensor detects the pressure inside
the refrigerant line and sends a voltage signal to the ECM. If the system pressure rises above or falls below
the following values, the ECM requests the IPDM E/ R to de-energize the A/C relay and disengage the com-
pressor.
• 3.12 MPa (31.82 kg/cm
2, 452.4 psi) or more (When the engine speed is less than 1,500 rpm)
• 2.74 MPa (27.95 kg/cm
2, 397.3 psi) or more (When the engine speed is 1,500 rpm or more)
• 0.14 MPa (1.43 kg/cm
2, 20.3 psi) or less
Compressor Oil Cir culation Control
When the engine starts while the engine coolant temperature is 56 °C (133° F) or less, ECM activates the com-
pressor for approximately 6 seconds and circulates the compressor oil once.
Air Conditioning Cut Control
When the engine is under a high load condition, the ECM transmits an A/C relay OFF request to IPDM E/R,
and stops the compressor. Refer to EC-37, "
AIR CONDITIONING CUT CONTROL : System Description".
