Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. T he HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2
″-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electrical scale or of quality recycle/recharge equipment.
Precaution for Leak Detection DyeINFOID:0000000001328158
 The A/C system contains a fluorescent leak detection dy e used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
 Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
 The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995). The flu-
orescent dye leak detector should be used in conjunc tion with an electrical leak detector (SST: J-41995) to
pin-point refrigerant leaks.
 For the purpose of safety and customer’s satisfacti on, read and follow all manufacture’s operating instruc-
tions and precautions prior to performing the work.
 A compressor shaft seal should not necessarily be re paired because of dye seepage. The compressor shaft
seal should only be repaired after confirming the l eak with an electrical leak detector (SST: J-41995).
 Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiagnosis during a future service.
 Never allow dye to come into contact with painted body panels or interior components. If dye is spilled, clean
immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of time
cannot be removed.
 Never spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
 Never use more than one refrigerant dye bot tle (1/4 ounce /7.4 cc) per A/C system.
 Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Never use HFC-
134a (R-134a) leak detection dye in CFC-12 (R-12) A/ C system, or CFC-12 (R-12) leak detection dye in
HFC-134a (R-134a) A/C system, or A/C system damage may result.
 The fluorescent properties of the dye will remain for thr ee years or a little over unless a compressor malfunc-
tion occurs.
IDENTIFICATION
NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.

DIAGNOSIS PROCEDURE FOR INSUFFICIENT COOLING
SYMPTOM: Insufficient cooling
1.CHECK POWER SUPPLY FOR ECV (ELECTRONIC CONTROL VALVE)
1. Disconnect compressor (ECV) connector.
2. Turn ignition switch ON.
3. Check voltage between compressor (ECV) harness connector F6 terminal 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check power supply circuit and 10A fuse [No. 12, located in the fuse block (J/B)]. Refer to PG-77
.
 If fuse is OK, check harness for open circuit. Repair or replace if necessary.
 If fuse is NG, check harness for short circuit and replace fuse.
2.CHECK ECV CONTROL SIGNAL
1. Turn ignition switch OFF.
2. Reconnect compressor (ECV) connector.
3. Perform self-diagnosis. Refer to ATC-43, "
Self-Diagnosis Function".
4. Set in self-diagnosis STEP-4 (Code No. 45). Refer to ATC-43, "
Self-Diagnosis Function".
5. Confirm ECV control signal between unified meter and A/C amp. harness connector M57 terminal 45 and ground using an oscillo-
scope.
Gauge indication Refrigerant cycle Probable cause Corrective action
Low-pressure side becomes nega-
tive. Liquid tank or front/rear side of
expansion valve’s pipe is frost-
ed or wet with dew.High-pressure side is closed
and refrigerant does not flow.
↓
Expansion valve or liquid tank
is frosted.Leave the system at rest until
no frost is present. Start it
again to check whether or not
the malfunction is caused by
water or foreign particles.
 If water is the cause, initially
cooling is okay. Then the wa-
ter freezes causing a block-
age. Drain water from
refrigerant or replace refrig-
erant.
 If due to foreign particles, re-
move expansion valve and
remove the particles with dry
and compressed air (not
shop air).
 If either of the above meth- ods cannot correct the mal-
function, replace expansion
valve.
 Replace liquid tank.
 Check lubricant for contami-
nation.

TROUBLE DIAGNOSIS
Ambient Sensor Circuit
INFOID:0000000001328196
COMPONENT DESCRIPTION
Ambient Sensor
The ambient sensor is attached on the hood lock stay. It detects
ambient temperature and converts it into a resistance value which is
then input into the unified meter and A/C amp.
AMBIENT TEMPERATURE INPUT PROCESS
The unified meter and A/C amp. includes a processing circ uit for the ambient sensor input. However, when the
temperature detected by the ambient sensor increases quickly, the processing circuit retards the unified meter
and A/C amp. function. It only allows the unified mete r and A/C amp. to recognize an ambient temperature
increase of 0.33 °C (0.6 °F) per 100 seconds.
As an example, consider stopping fo r a few minutes after high speed driving. Although the actual ambient tem-
perature has not changed, the temperature detected by t he ambient sensor will increase. This is because the
heat from the engine compartment can radiate to the front grille area, location of the ambient sensor.

NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other source s. It is not a malfunction.
 Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun- tains or buildings blocking the signal.
 Multi-path noise: This noise results from a time di fference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.

Locking CD Auto-Changer MechanismINFOID:0000000001328690
CAUTION:
 Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the changer mechanism MUST BE LOCKED to prevent the mech anism from being damaged during shipping.
 If a CD is jammed or unable to be removed from th e unit, do NOT lock the changer mechanism. If the
unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism
sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the
same disc selection button again within 5 seconds.
 The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism s ound stops), open the driver and passenger window, and
then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.
