< PRECAUTION >
PRECAUTIONS
• Before starting repairs which do not require battery power:Turn off ignition switch.
Disconnect the negative battery terminal.
• If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
• To prevent serious burns: Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
• Dispose of drained oil or the solvent used for cleaning parts in an
appropriate manner.
• Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
• Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
• Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
• After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.
• Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.

SYSTEM
Control by ECM- Cooling fan control
Refer to EC-60, "COOLING FAN CONTROL : System Description (with manual air conditioner)"
(QR25DE)
or EC-575, "COOLING FAN CONTROL : System Description"
(VQ35DE).
- Air conditioning cut control Refer to EC-57, "AIR CONDITIONING CUT CONTROL : Sy stem Description (with manual air conditioner)"
(QR25DE) or EC-573, "AIR CONDITIONING CUT CONTROL : System Description" (VQ35DE).
Control by IPDM E/R
- Relay control
Refer to PCS-6, "RELAY CONTROL SYSTEM : System Description"
.
- Cooling fan control
Refer to EC-60, "COOLING FAN CONTROL : System Description (with manual air conditioner)"
(QR25DE)
or EC-575, "COOLING FAN CONTROL : System Description"
(VQ35DE).
Air Flow ControlINFOID:0000000009463196
DESCRIPTION
• Front air control changes duty ratio of front blower mo tor control signal to control air flow continuously. When
air flow is increased, duty ratio of front blower mo tor control signal gradually increases to prevent a sudden
increase in air flow.
• In addition to manual control, air flow control is composed of fan speed control at door motor operation.
FAN SPEED CONTROL AT DOOR MOTOR OPERATION
When mode door motor is activated while air flow is more than the specified value, front air control temporarily
reduces fan speed so that mode door moves smoothly.
Air Inlet ControlINFOID:0000000009463197
The intake door position is automatically controlled in MAX A/C and DEF modes. The intake door is controlled
by customer input in the other modes.
Air Outlet ControlINFOID:0000000009463198
Air outlet control is controlled by customer input. When t he A/C is turned off by turning the blower control dial
fully counterclockwise, the front air control retains the current selections and returns to these selections the
next time the blower control dial is turned to any fan position.
NOTE:
If ambient temperature is excessively low, D/F is se lected to prevent windshield fogging when air outlet is set
to FOOT.
Compressor ControlINFOID:0000000009463199
DESCRIPTION
In order for the IPDM E/R to complete a compress or ON request, the following conditions must be met:
1. The BCM detects a Fan ON signal from the front air control. The front air control grounds the fan ON sig-
nal monitored by the BCM when the blower speed dial is in any of the fan speed positions.
2. The BCM detects an A/C ON signal from the front air control. The front air control grounds the A/C ON sig-
nal monitored by the BCM when:
- The A/C switch is pressed. The A/C switch LED ill uminates and the front air control grounds the A/C ON
signal monitored by the BCM. Any mode c ontrol button except D/F may be selected.
- The A/C switch is OFF, and the MAX A/C button is pr essed. The A/C switch LED will automatically illumi-
nate and the front air control grounds the A/C ON signal monitored by the BCM.
- The A/C switch is OFF, and the mode button for either D/F or DEF is selected. The front air control
grounds the A/C ON signal monitored by the BCM, but it does not illuminate the A/C switch LED
NOTE:
If the compressor was engaged by pressing the D/F or DE F mode buttons, and the time spent in either mode
exceeds 1 minute, then the compressor stays reques ted, even when modes other than D/F or DEF are
selected, until either:
1. The ignition switch is turned OFF.

UIT FOR FRONT AIR CONTROL
DescriptionINFOID:0000000009463219
COMPONENT DESCRIPTION
Front air control.
The front air control has a built-in microcomputer that processes inform ation sent from various sensors
needed for air conditioner operation. The air mix door motor, the mode door motor, the intake door motor, the
blower motor and the A/C compressor are then controlled.
Component Function CheckINFOID:0000000009463220
1.CHECK OPERATION
1. Turn the blower motor dial clockwise and verify t he blower speed increases and that one of the LEDs illu-
minates on the mode switch.
2. Press the mode switches and verify that the modes change, the LEDs illuminate, and that air flows from
the various vents.
3. Turn the temperature control dial and verify the temperature changes at the selected vents.
4. Press the DEF and REC buttons and verify air flow changes.
Does it operate normally?
YES >> Inspection End.
NO >> Perform trouble diagnosis for the front air control system. Refer to HAC-152, "Diagnosis Proce-
dure".
