Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must equip positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite to the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers do
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. The hose fitting must
be 1/2″-16 ACME if the scale controls refrigerant flow electronically.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale each three month.
To calibrate the weight scale on the ACR4:
1. Press “Shift/Reset” and “Enter” at the same time.
2. Press “8787”. “A1” is displayed.
3. Remove all weight from the scale.
4. Press “0”, then press “Enter”. “0.00” is displayed and change to “A2”.

PRECAUTIONS
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb.) on the center
of the weight scale.
6. Enter the known weight using four digits. (Example 10 lb. = 10.00, 10.5 lb. = 10.50)
7. Press “Enter”— the display returns to the vacuum mode.
8. Press “Shift/Reset” and “Enter” at the same time.
9. Press “6”— the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00” is displayed.
11. Press “Shift/Reset” to return the ACR4 to the program mode.
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 accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

The set temperature is increased or decreased with this dial.
Temperature Control Dial (Passenger Side)
 The set temperature is increased or decreased with this dial.
 When the temperature control dial is turned, DUAL switch indicator is turned ON.
AUTO Switch
 The compressor, intake door, air mix doors, mode doors and blower speed are automatically controlled so
that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the operator.
 When pressing the AUTO switch, air inlet, air outlet, fan speed, and discharge air temperature are automati-
cally controlled.
Defroster (DEF) Switch
Mode doors are set to the defrost position with this switch. Also, intake door is set to the outside air position,
and compressor turns ON.

A/C AUTO AMP.
A/C AUTO AMP.
DescriptionINFOID:0000000003941321
COMPONENT DESCRIPTION
A/C Auto Amp. (Air Conditioner Automatic Amplifier)
The A/C auto amp. (1) has a built-in microcomputer that processes
information sent from various sensors needed for air conditioner
operation. The air mix door motors, the mode door motor, the intake
door motor, the blower motor and the compressor are then con-
trolled.
When the various switches and temperature control dial are oper-
ated, data is input to the A/C auto amp. from the A/C control.
Component Function CheckINFOID:0000000003940728
1.CHECK OPERATION
1. Press the AUTO switch, and then check that “AUTO” is shown on the display.
2. Operate the temperature control dial (driver side). Check that the fan speed or outlet changes. (The dis-
charge air temperature or fan speed varies depending on the ambient temperature, in-vehicle tempera-
ture, and temperature setting.)
Does it operate normally?
YES >> INSPECTION END
NO >> Perform trouble diagnosis for the A/C system. Refer to HAC-192, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003940729
1.INSPECTION BY FAIL-SAFE FUNCTION
1. Turn the ignition switch ON.
2. After approximately 30 seconds, check that the air conditioner is operated by the fail-safe function (the
operation display of air conditioner is not performed). Refer to HAC-211, "
WITHOUT INTELLIGENT AIR
CONDITIONER SYSTEM : Fail-Safe" (WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM) or HAC-
223, "WITH INTELLIGENT AIR CONDITIONER SYSTEM : Fail-Safe" (WITH INTELLIGENT AIR CONDI-
TIONER SYSTEM).
Is the fail-safe function operated?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK A/C AUTO AMP. POWER SUPPLY CIRCUIT AND GROUND
Check A/C auto amp. power supply circuit and ground circuit. Refer to HAC-192, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace parts according to the inspection results.
3.CHECK PRESET SWITCH
Check the preset switch. Refer to AV-164, "
Symptom Table" (BASE AUDIO AND DISPLAY SYSTEM), AV-372,
"Symptom Table" (BOSE AUDIO WITHOUT NAVIGATION) or AV-640, "Symptom Table" (BOSE AUDIO WITH
NAVIGATION).
Is the inspection result normal?
YES >> Replace the A/C auto amp.
NO >> Repair or replace parts according to the inspection results.
