FLUORESCENT LEAK DETECTOR
General Precautions
INFOID:0000000003846404
CAUTION:
• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An
ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages.
• Always wear fluorescence enhancing UV safety goggles to protect 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 fluorescent dye leak detector should be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leakages.
• Read and follow all manufacture operating instructions and precautions prior to performing the work
for the purpose of safety and customer satisfaction.
• A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-
sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector
(SST: J-41995).
• Always remove any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during future service.
• Never allow dye to come into contact with painted body panels or interior components. Clean imme-
diately with the approved dye cleaner if dye is spilled. 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 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. 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 remains for three or more years 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.
IDENTIFICATION LABEL FOR VEHICLE
Vehicles with factory installed fluorescent dye have an identification label on the front side of hood.

>> GO TO 2.
NO
>> Memory function malfunction:
HAC-236, "Inspection procedure"
2.
CHECK BLOWER MOTOR SPEED
1.
Start the engine.
2.
Operate the fan control dial. Check that the fan speed changes. Check the operation for all fan speeds.
3.
Set the fan speed to speed 7.
Is the inspection result normal?
YES
