PRECAUTIONS
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to an
CFC-12 (R-12) A/C system. The 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 1/2²-16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. Press “Shift/Reset”and“Enter”at the same time.
2. Press “8787”.“A1” will be displayed.
3. Remove all weight from the scale.
4. Press “0”, then press “Enter”.“0.00” will be displayed and change to “A2”.
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” will be 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.
Precautions for Leak Detection DyeEJS0062B
lThe A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
lAlways wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
lThe fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector (J-
41995) to pin-point refrigerant leaks.
lFor your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.

AIR CONDITIONER CONTROL
AIR CONDITIONER CONTROL
PFP:27500
DescriptionEJS005FW
The front air control provides regulation of the vehicle's interior temperature. The system is based on the posi-
tion of the front air controls temperature switch selected by the driver. This is done by utilizing a microcom-
puter, also referred to as the front air control, which receives input signals from the following three sensors:
lIntake sensor
lPBR (Position Balanced Resistor).
The front air control uses these signals (including the set position of the temperature switch) to control:
lOutlet air volume
lAir temperature
lAir distribution
The front air control is used to select:
lOutlet air volume
lAir temperature/distribution
OperationEJS005FX
AIR MIX DOOR CONTROL
The air mix door is controlled so that in-vehicle temperature changed based on the position of the temperature
switch.
BLOWER SPEED CONTROL
Blower speed is controlled based on front blower switch settings.
When blower switch is turned, the blower motor starts and increases air flow volume each time the blower
switch is turned counterclockwise, and decreases air flow volume each time the blower switch is turned coun-
terclockwise.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flow-
ing.
INTAKE DOORS CONTROL
The intake doors are controlled by the recirculation switch setting, and the mode (defroster) switch setting.
MODE DOOR CONTROL
The mode door is controlled by the position of the mode switch.
DEFROSTER DOOR CONTROL
The defroster door is controlled by: Turning the defroster dial to front defroster.

Operational CheckEJS005GB
The purpose of the operational check is to confirm that the system operates properly.
CHECKING BLOWER
1. Turn blower control switch clockwise. Blower should operate on
low speed. The blower symbol should have one blade lit (on dis-
play).
2. Turn the blower control switch again, and continue checking
blower speed and blower symbol until all speeds are checked.
3. Leave blower on MAX speed.
If NG, go to trouble diagnosis procedure for
