PRECAUTIONS
Revision: June 20062007 Versa
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 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 oils have been used with the scale. If the scale controls refriger-
ant 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 accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precautions for Leak Detection DyeEJS00572

The 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.

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 electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pin-
point refrigerant leaks.

For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.

A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector.

Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a future service.

Do not 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.

Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).

Do not use more than one refrigerant dye bottle (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. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detector 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 over three (3) years unless a compressor malfunction
occurs.
IDENTIFICATION LABEL FOR VEHICLE
Vehicles with factory installed fluorescent dye have this identification label on the front side of hood.

Operational CheckEJS0057J
The purpose of the operational check is to confirm that the system operates properly.
CHECKING BLOWER
1. Turn blower control dial clockwise to "1" position. Blower should operate on low speed.
2. Turn blower control dial clockwise to "2" position, and continue checking blower speed until all speeds are
checked.
3. Leave blower on Maximum speed.
If NG, go to trouble diagnosis procedure for MTC-37, "
Blower Motor Circuit" .
If OK, continue the check.
CHECKING DISCHARGE AIR
1. Turn mode door control dial to each position.
2. Confirm that discharge air comes out according to the air distribution table. Refer to MTC-22, "
Discharge
Air Flow" .
If NG, go to trouble diagnosis procedure for MTC-34, "
Mode Door" .
If OK, continue the check.
CHECKING RECIRCULATION
1. Set intake door lever to REC position.
2. Operate intake door lever to FRE position.
3. Listen for intake door position change (you should hear blower sound change slightly).
If NG, go to trouble diagnosis procedure for MTC-36, "
Intake Door" .
If OK, continue the check.
CHECKING TEMPERATURE DECREASE
1. Turn temperature control dial counterclockwise to full cold position.
2. Check for cold air at discharge air outlets.
If NG, go to trouble diagnosis procedure for MTC-50, "
Insufficient Cooling" .
If OK, continue the check.
CHECKING TEMPERATURE INCREASE
1. Turn temperature control dial clockwise to full hot position.
2. Check for hot air at discharge air outlets.
If NG, go to trouble diagnosis procedure for MTC-58, "
Insufficient Heating" .
If OK, continue the check.
CHECKING A/C SWITCH (IF EQUIPPED)
1. Turn fan control dial to the desired (1 to 4 speed) position.
2. Press A/C switch.
3. A/C switch indicator will turn ON.

Confirm that the compressor clutch engages (sound or visual inspection).
If NG, go to trouble diagnosis procedure for MTC-41, "
Magnet Clutch Circuit (If Equipped)" .
If OK, continue the check.
CHECKING DEFROST A/C SWITCH (IF EQUIPPED)
1. Turn fan control dial to the desired (1 to 4 speed) position.
2. Turn mode dial to ( ) DEF.
3. Confirm that the compressor clutch engages (sound or visual inspection).
If NG, go to trouble diagnosis procedure for MTC-41, "
Magnet Clutch Circuit (If Equipped)" .
If all operational checks are OK (symptom cannot be duplicated), go to MTC-24, "
How to Perform Trouble
Diagnosis for Quick and Accurate Repair" and perform tests as outlined. If symptom appears, refer to MTC-
24, "SYMPTOM TABLE" and perform applicable trouble diagnosis procedures. Conditions : Engine running at normal operating temperature
