not go off after activating.
1 CHECK REAR WINDOW DEFOGGER OUTPUT SIGNAL
1. Turn ignition switch to ON position.
2. Check voltage between time control unit harness terminal 13 and ground.
NEL668
OK or NG
OK©Check the following.
+Rear window defogger relay
(Refer to EL-205.)
+Rear window defogger circuit
+Rear window defogger filament
(Refer to EL-206.)
NG©GO TO 2.
2 CHECK DEFOGGER RELAY COIL SIDE CIRCUIT
1. Disconnect control unit connector.
2. Turn ignition switch to ON position.
3. Check voltage between time control unit terminal 13 and ground.
NEL669
OK or NG
OK©GO TO 3.
NG©Check the following.
+10A fuse [No. 10, located in the fuse block (J/B)]
+Rear window defogger relay
+Harness for open or short between 10A fuse [No. 10, located in the fuse block (J/B)]

Filament Check=NLEL00771. Attach probe circuit tester (in volt range) to middle portion of
each filament.
SEL122R
+When measuring voltage, wrap tin foil around the top of
the negative probe. Then press the foil against the wire
with your finger.
SEL265
2. If a filament is burned out, circuit tester registers 0 or 12 volts.
SEL266
3. To locate burned out point, move probe to left and right along
filament. Test needle will swing abruptly when probe passes
the point.

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 and verify that battery positive volt-
age 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
defogger 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 AUTOCHANGERNLEL0385S06Testing Magazines and DiscsNLEL0385S06011. 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.
Locking CD Changer Unit MechanismNLEL0385S0602CAUTION:
+Prior to removing a malfunctioning CD changer unit that will be shipped for repair, the changer
mechanism MUST BE LOCKED to prevent the mechanism from being damaged during shipping.
