A. RH front of engine compartment B. Behind LH side of front fascia No. Component Description
1. ECM The ECM sends a compressor ON request to the IPDM E/R based on the status of engine
operation and load as well as refrigerant pressure information. If all the conditions are met for
A/C operation, the ECM transmits the compressor ON request to the IPDM E/R.
2. IPDM E/R A/C relay is integrated in IPDM E/R. IPDM
E/R operates A/C relay when receiving A/C com-
pressor request signal from ECM via CAN communication line.
3. A/C compressor Vaporized refrigerant is drawn into the A/C compressor from the evaporator, where it is com-
pressed to a high pressure, high temperature vapor. The hot, compressed vapor is then dis-
charged to the condenser.
4. Refrigerant pressure sensor Refer to EC-27, "
Refrigerant Pressure Sensor".

No. Component Description
1. BCM The BCM receives the fan ON and A/C ON signals from the front air control and sends a com-
pressor ON request to the ECM.
2. Fuse Block (J/B) Located in the passenger compartment, behind the left lower IP, the Fuse Block (J/B) con-
tains the front blower motor relay and several fuses required for the air conditioner control
system.
3. Blower relay The blower relay controls the flow of current to fuse 20, 21 and 22 in the Fuse Block (J/B).
The relay is connected directly to ground, and is energized when the ignition switch is in the
ON or START position.
4. Front blower motor The front blower motor varies the speed at which the air flows through the ventilation system.
5. Front blower motor resistor Ground for the blower is supplied through blower resistor and the blower speed switch. As
the switch is moved from position 1 through 4, more current is allowed to flow through the
motor, for a higher speed. This is because less resistors are in the path as the switch is
moved to a higher position. When the switch is on the highest position, all resistors are by-
passed.
6. Thermo control amp. Thermo control amp. is composed of thermistor and amplifier. When the A/C switch signal is
received from the front air control, the thermo control amp. transmits the A/C ON signal to the
BCM according to evaporator fin temperature. When the thermistor detecting temperature of
the air that passes through evaporator is extremely low, the thermo control amp. sends the
A/C OFF signal to BCM, and stops the compressor.
7. Front air control The front air control controls the operation of the A/C and heating system.

DESCRIPTION
• When A/C switch signal is received from front air control, the thermo control amp. transmits A/C ON signal to
the BCM according to evaporator fin temperature.
• When the front blower motor is operated, the front air control transmits blower fan ON signal to the BCM.
• BCM transmits the A/C ON signal and blower fan ON signal to ECM via CAN communication line. Refer to LAN-25, "
CAN COMMUNICATION SYSTE M : System Description"
• 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 EC M, IPDM E/R turns the A/C relay to ON, and acti-
vates the compressor. Refer to PCS-5, "
RELAY CONTROL SYSTEM : System Description".

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".

MAGNET CLUTCH
DescriptionINFOID:0000000012430746
SYSTEM DESCRIPTION
When the blower speed dial is in one of the fan speed pos itions, the front air control outputs a fan ON signal to
the BCM. When the A/C switch is pressed, the A/C switch LED illuminat es and the front air control outputs a
compressor ON signal to the BCM. Any mode control button can be selected. As long as the BCM receives a
compressor ON signal and a fan ON signal from the front air control, the conditions required for the BCM to
transmit a compressor ON request to the ECM have been met.
The BCM sends a compressor ON signal to ECM, via CAN communication line.
The ECM judges whether the compressor can be turned ON, based on each sensor status (refrigerant pres-
sure sensor signal, throttle angle sensor, etc.). If it judges the compressor can be turned ON, it sends a com-
pressor ON signal to IPDM E/R, via CAN communication line.
Upon receipt of a compressor ON signal from ECM, IPDM E/R turns the A/C relay ON to operate the compres-
sor.

The BCM controls power and ground to all interior lamps.
After the battery saver system turns the la mps OFF, the lamps will illuminate again when
• a signal is received from a key fob, main power window and door lock/unlock switch, power window and
door lock/unlock switch RH or when the front door lock assembly LH (key cylinder switch) is locked or
unlocked
• a door is opened or closed
• the key is removed from or inserted into t he ignition switch (without Intelligent Key system).
The interior lamp battery saver control time per iod can be changed with the function setting of CONSULT.
ILLUMINATION CONTROL SYSTEM
ILLUMINATION CONTROL SYSTEM : System DescriptionINFOID:0000000012432723
SYSTEM DIAGRAM
OUTLINE
The illumination lamps operation is dependent upon the posit ion of the combination switch (lighting and turn
signal switch). When the combination switch (lighting and turn signal switch) is placed in the 1ST or 2ND posi-
tion the BCM (body control module) receives input requesting the parking lamps to illuminate. This input is
communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communica-
tion lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized,
this relay directs power to the parking and illumination lamps, which then illuminate.
BATTERY SAVER CONTROL
When the combination switch (lighting and turn signal switch) is in the 1st or 2nd position and the ignition
switch is turned from ON or ACC to OFF, the battery saver control feature is activated. Under this condition,
the illumination lamps remain illuminated for 10 minutes unless the combination switch (lighting and turn signal
switch) position is changed. If the combination switch (lighting and turn signal switch) position is changed, then
the illumination lamps are turned off after a 15 second delay. When the combination switch (lighting and turn
signal switch) is turned from OFF to 1st or 2nd position after illumination lamps have been turned off by the
battery saver control, the illumination lamps illuminate again.
