• Blower fan ON signal: ON
• Thermo control amp. signal: ON
• ECM judges the conditions of each sensor (Refrigerant pressure sensor signal, accelerator position signal,
etc.), and transmits the A/C compressor request signal to IPDM E/R via CAN communication line.
• By receiving the A/C compressor request signal from ECM, IPDM E/R turns the A/C relay to ON, and acti-
vates the compressor.
PCS-7, "RELAY CONTROL SYSTEM : System Description"
CONTROL BY THERMO CONTROL AMP.
Low Temperature Protection Control
• When the thermo control amp. detects that evaporator fin tempera-
ture is 2
°
C (36
°
F) or less, thermo control amp. signal becomes
OFF, and stops the compressor.
• When the air temperature returns to 3.5
°
C (38
°
F) or more, the
compressor is activated.
Operating Rate Control
• Thermo control amp. detects the positions of temperature control dial (air mix PBR) and MODE dial (MODE
switch).
• Thermo control amp. corrects the stopping temperature of A/C compressor depending on the condition of A/
C operation, and prevents too much heating by turning thermo control amp. signal ON
⇔
OFF.
CONTROL BY ECM
Compressor Protection Control at Pressure Malfunction
When the high-pressure side value that is detected by refrigerant pressure sensor is as per the following state,
ECM requests IPDM E/R to turn A/C relay OFF and stops the compressor.
• 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 Circulation 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 condition is high load, ECM transmit A/C relay OFF request to IPDM E/R, and stops the
compressor.
