Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it is important to note the position the seat is in and the load placed on the seat
when the noise occurs. These conditions must duplicated when verifying and isolating the cause of the noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

FLUORESCENT LEAK DETECTOR
FLUORESCENT LEAK DETECTOR
General PrecautionsINFOID:0000000003795892
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.
 Wear always 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). The fluo-
rescent dye leak detector should be used in conjunction with an electrical leak detector (SST) to pin-
point refrigerant leakages.
 Read and follow all manufacture’s operating instructions and precautions prior to performing the
work for the purpose of safety and customer’s 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).
 Remove always any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during a 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 the identification label on the front side of hood.

 Ignition switch ON
 Any of the following conditions with ignition switch OFF
- Engine start permission is entered.
- Intelligent Key inserted into the key slot.
- Driver door is LOCK → UNLOCK.
- Driver door is open.
Push-button Ignition Switch Illumination OFF Operation
BCM turns the push-button ignition switch illumination OFF in any of the following conditions.
 The push-button ignition switch illumination ON conditions do not satisfy.
 All of the following conditions with ignition switch OFF
- The push-button ignition switch illumination ON conditions do not change (15 seconds after the ignition
switch OFF) or the driver door is UNLOCK → LOCK.
