DISASSEMBLY
Revision: 2005 July 2005 FX
28. Remove oil pan and oil pan gasket.
29. Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.
If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 5 , "
A/T Fluid Cooler Cleaning" .
30. Remove magnets from oil pan.
31. Disconnect A/T fluid temperature sensor 2 connector. CAUTION:
Be careful not to damage connector.
32. Straighten terminal clips to free terminal cord assembly and A/T fluid temperature sensor 2 harness.

PRECAUTIONS
Revision: 2005 July 2005 FX
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Never confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.
O-Ring Part Numbers and Specifications
WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
When the compressor is removed, store it in the same way as it is when mounted on the car. Fail-
ure to do so will cause lubricant to enter the low-pressure chamber.
When connecting tubes, always use a torque wrench and a back-up wrench.
After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
When installing an air conditioner in the vehicle, connect the pipes at the final stage of the opera-
tion. Never remove the seal caps of pipes and other components until just before required for con-
nection.
Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
Always replace used O-rings.
When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
O-ring must be closely attached to dented portion of tube.
When replacing the O-ring, be careful not to damage O-ring and tube.
Connect tube until a click can be heard, then tighten the nut or bolt by hand until snug. Make sure
that the O-ring is installed to tube correctly.

Maintenance of Lubricant Quantity in CompressorAJS00149
The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large refrigerant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:
Lack of lubricant: May lead to a seized compressor.
Excessive lubricant: Inadequate cooling (thermal exchange interference)
LUBRICANT
LUBRICANT RETURN OPERATION
Adjust the lubricant quantity according to the test group shown below.
1. CHECK LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
A/C system works properly.
There is no evidence of a large amount of lubricant leakage.
CAUTION:
If excessive lubricant leakage is noted, never perform the lubricant return operation.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS
1. Start engine, and set the following conditions:
–Engine speed: Idling to 1,200 rpm
–A/C switch: ON
–Blower speed: Max. position
–Temp. control: Optional [Set so that intake air temperature is 25 to 30 °C (77 to 86 °F).]
–Intake position: Recirculation (REC)
2. Perform lubricant return operation for about 10 minutes.
3. Stop engine.
>> GO TO 3.
3. CHECK REPLACEMENT PART
Should the compressor be replaced?

Starting Fan Speed Control
Start up from COLD SOAK Condition (Automatic mode)
In a cold start up condition where the engine coolant temperature is below 56 °C (133 °F), the blower will not
operate for a short period of time (up to 150 seconds). The exact start delay time varies depending on the
ambient and engine coolant temperature.
In the most extreme case (very low ambient) the blower starting delay will be 150 seconds as described
above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above
56 °C (133 °F), and then the blower speed will increase to the objective speed.
Start up from usual or HOT SOAK Condition (Automatic mode)
The blower will begin operation momentarily after the AUTO switch is pushed. The blower speed will gradually
rise to the objective speed over a time period of 3 seconds or less (actual time depends on the objective
blower speed).
Blower Speed Compensation
Sunload
When the in-vehicle temperature and the set temperature are very close, the blower will be operating at low
speed. The low speed will vary depending on the sunload. During conditions of low or no sunload, the blower
speed is at duty ratio 25%. During high sunload conditions, the unified meter and A/C amp. raise the blower
speed (duty ratio 49%).
Fan Speed Control Specification
COMPONENT DESCRIPTION
Brush-Less Motor
The blower motor utilizes a brush-less motor with a rotating magnet.
Quietness is improved over previous motors where the brush was
the point of contact and the coil rotated.
DIAGNOSIS PROCEDURE FOR BLOWER MOTOR
SYMPTOM: Blower motor operation is malfunctioning.

5. Disconnect one-touch joint between high-pressure pipe 1 and 2.
a. Set a disconnector (SST: 9253089908) on A/C piping.
b. Slide a disconnector toward vehicle rear until it clicks.
c. Slide A/C piping toward vehicle rear and disconnect it. CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
6. Remove high-pressure pipe 1.
7. Disconnect one-touch joint between high-pressure pipe 2 and 3.
a. Set a disconnector (SST: 9253089908) on A/C piping.
b. Slide a disconnector toward vehicle front until it clicks.
c. Slide A/C piping toward vehicle front and disconnect it.
8. Remove high-pressure pipe 2. CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
Replace O-rings of high-pressure pipe with new ones, and then apply compressor oil to it when
installing it.
Connection point for female-side piping is thin. So, when inserting male-side piping, take care not
to deform female-side piping. Slowly insert in axial direction.
Insert one-touch joint connection point securely until it clicks.
After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.
When recharging refrigerant, check for leaks.
Removal and Installation of Low-Pressure Pipe 2 and High-Pressure Pipe 3AJS001BI
REMOVAL
1. Set the temperature (passenger side) at 18 °C (60 °F), and then disconnect the battery cable from the neg-
ative terminal.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
3. Remove cowl top cover. Refer to EI-23, "
COWL TOP" .
4. Remove mounting bolts from low-pressure pipe 1 bracket and low-pressure flexible hose bracket.

UNIFIED METER AND A/C AMP
Revision: 2005 July 2005 FX
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionAKS005N8
For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.
Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to AT C - 3 0 , "
AIR CONDITIONER CONTROL" in ATC section.
Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.
And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.
The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) display control unit (with NAVI) using
CAN communication.
Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.
The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor, data monitor).
