PRECAUTIONS

Precautions for Leak Detection DyeAJS00141

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 (J-
41995) 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 (J-41995).

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
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 this identification
label on the front side of hood.
Wiring Diagrams and Trouble DiagnosisAJS00142
When you read wiring diagrams, refer to the following:

GI-15, "How to Read Wiring Diagrams" in GI section.

PG-4, "Wiring Diagram - POWER -" in PG section.
When you perform trouble diagnosis, refer to the following:

GI-11, "How to Follow Trouble Diagnoses" in GI section.

GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section.

PREPARATION

HFC-134a (R-134a) Service Tools and EquipmentAJS00144
Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or
its lubricant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubri-
cant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor malfunction will result.

Color of RGB Image is Not Proper (All Screens Looks Yellowish)" .
VEHICLE SIGNALS

A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
CAUTION:
In case of confirming light signal, set D/N mode to ON/OFF
of lighting switch (normal setting).

OFF: D (Day mode)

ON: N (Night mode)
Unless above setting, light signal (ON/OFF) may not be
accurately displayed.

If vehicle speed is NG, refer to AV- 1 5 0 , "Vehicle Speed Signal Check for Display Control Unit" .

If light is NG, refer to AV- 1 5 2 , "Illumination Signal Check for Display Control Unit" .

If IGN is NG, refer to AV- 1 5 2 , "Ignition Signal Check for Display Control Unit" .

If reverse is NG, refer to AV- 1 5 3 , "Reverse Signal Check for Display Control Unit" .
