3. If leakage occurs around luggage room, remove luggage room
side trim and check connecting area. Check for proper
connection, damage or tear.
4. Remove drain hoses and check visually for any damage,
cracks, or deterioration.
5. Pour water into drain hoses and find damaged portion.
+If any damaged portion is found at each step, replace the
damaged part.
WEATHERSTRIPNJBT0022S05+In the case of leakage around glass lid, close glass lid and pour
water over glass lid to find damaged or gap portion.
1. Remove glass lid assembly. (Refer to removal procedures,
BT-63, for details.)
2. Visually check weatherstrip for proper installation. If a gap
exists between glass lid and weatherstrip, check for sufficient
amount of butyl seal. If required, remove weatherstrip and

3. Check weatherstrip visually for any damage, deterioration, or
flattening.
+If any damage is found, replace weatherstrip.
CAUTION:
Do not remove weatherstrip except when replacing, or filling
up butyl seal.
LINK AND WIRE ASSEMBLYNJBT0022S06NOTE:
Before replacing a suspect part, carefully ensure it is the source of
noise being experienced.
1. Check link to determine if coating film has peeled off to such
an extent that substrate is visible. Check also to determine if
link is the source of noise. If it is, replace it.
2. Visually check to determine if a sufficient amount of petroleum
jelly has been applied to wire or rail groove. If not, add petro-
leum jelly as required.
3. Check wire for any damage or deterioration. If any damage is
found, remove rear guide (refer to removal procedures, BT-63,
for details), then replace wire.

CD AUTOCHANGERNJEL0385S06Testing Magazines and DiscsNJEL0385S06011. Confirm discs are installed correctly into the magazine (not upside down).
2. Visually inspect/compare the customer's discs with each other and other discs.
Identify any of the following conditions:
+Discs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
+Discs with rough or lipped edges.
+Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
+Discs with scratches, abrasions, or pits on the surface.
+Discs with grease/oil, fingerprints, foreign material.
+Discs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions.
Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
NOTE:
+Discs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automotive environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
+Use a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.
