< SYSTEM DESCRIPTION >

[MANUAL AIR CONDITIONING]

HAC

• 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.

Refer to

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

, 452.4 psi) or more (When the engine speed is less than 1,500 rpm)

• 2.74 MPa (27.95 kg/cm

, 397.3 psi) or more (When the engine speed is 1,500 rpm or more)

• 0.14 MPa (1.43 kg/cm

, 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.
