3. CHECK VEHICLE SPEED SIGNAL
1. Connect audio unit and unified meter and A/C amp. connectors.
2. Start engine and drive vehicle at more than 40 km/h (25 MPH).
3. Check the signal between audio unit harness connector M60 terminal 22 and ground with CONSULT-II or oscilloscope.
OK or NG
OK >> INSPECTION END (System is OK.)
NG >> Replace unified meter and A/C amp.
Locking CD Auto-Changer MechanismNKS003B1
CAUTION:

Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the
changer mechanism MUST BE LOCKED to prevent the mechanism from being damaged during
shipping.

If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the same disc selection button again within 5 seconds.

The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.

ANTENNAPFP:28200
System DescriptionNKS003LP
With the ignition switch in ACC or ON, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to audio unit terminal 10.
Ground is supplied through the case of the antenna amp.
When the radio switch is turned ON, antenna signal is supplied

through audio unit terminal 5

to the antenna amp.
Then the antenna amp. is activated.
The amplified radio signals are supplied to the audio unit through the antenna amp.
