2. Disconnect fuel level sensor unit harness connector B29.
3. Connect a resistor (80W) between fuel level sensor unit har-
ness connector terminals 4 and 1.
4. Turn ignition switch ªONº.
The fuel warning lamp should come on.
NOTE:
For QG Engine Only
ECM might store the DTC P0180 during this inspection. If the DTC
is stored in ECM memory, erase the DTC after reconnecting the
fuel level sensor unit and fuel pump harness connector. Refer to

DIODE CHECKNJEL0051S03+Check continuity using an ohmmeter.
+Diode is functioning properly if test results are as shown in the
figure at left.
+Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer to
EL-108, ªWARNING LAMPº wiring diagrams.
NOTE:
Specification may vary depending on the type of tester. Before
performing this inspection, be sure to refer to the instruction

Trouble DiagnosesNJEL0385AUDIO UNITNJEL0385S05
Symptom Possible causes Repair order
Audio unit inoperative (no
digital display and no
sound from speakers).1. 10A fuse
2. Poor audio unit case ground
3. Audio unit1. Check 10A fuse [No. 1, located in fuse block (J/B)].
Turn ignition switch ON and verify that battery posi-
tive voltage is present at terminal 3 of audio unit.
2. Check audio unit case ground.
3. Remove audio unit for repair.
Audio unit presets are lost
when ignition switch is
turned OFF.1. 15A fuse
2. Audio unit1. Check 15A fuse [No. 32, located in fuse block (J/B)]
and verify that battery positive voltage is present at
terminal 9 of audio unit.
2. Remove audio unit for repair.
Individual rear speaker is
noisy or inoperative.1. Each speaker
2. Output circuit to each speaker1. Check speaker.
2. Check the output circuits to each speaker
+between audio unit and speaker amp.
+between speaker amp. and each speaker.
AM/FM stations are weak
or noisy.1. Roof antenna
2. Audio unit ground
3. Audio unit1. Check roof antenna.
2. Check audio unit ground condition.
3. Remove audio unit for repair.
Audio unit generates noise
in AM and FM modes with
engine running.1. Poor audio unit ground
2. Loose or missing ground bonding straps
3. Ignition condenser or rear window defog-
ger noise suppressor condenser
4. Ignition coil or secondary wiring
5. Audio unit1. Check audio unit ground.
2. Check ground bonding straps.
3. Replace ignition condenser or rear window defogger
noise suppressor condenser.
4. Check ignition coil and secondary wiring.
5. Remove audio unit for repair.
Audio unit generates noise
in AM and FM modes with
accessories on (switch
pops and motor noise).1. Poor audio unit ground
2. Antenna
3. Accessory ground
4. Faulty accessory1. Check audio unit ground.
2. Check antenna.
3. Check accessory ground.
4. Replace accessory.
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.
