NOTE:
If the radio has anti-theft function, check the anti-theft function of the radio before circuit inspection.
(Radios which have anti-theft function are equipped with a code indicator. For details, refer to EL-173.)
Speaker inspection
1. Disconnect speaker harness connector.
2. Measure the resistance between speaker terminalsj
1andj2.
+The resistance should be2-4W.
3. Using jumper wires, momentarily connect a 9V battery between speaker terminalsj
1andj2.
+A momentary hum or pop should be heard.
Antenna inspection
Using a jumper wire, clip an auxiliary ground between antenna and body.
+If reception improves, check antenna ground (at body surface).
+If reception does not improve, check main feeder cable for short circuit or open circuit.
Radio inspection
All voltage inspections are made with:
+Ignition switch ON or ACC
+Radio ON
+Radio connected (If removed for inspection, supply a ground to the case using a jumper wire.)

CATS (Code) System/RHD
NOTE:
+This system is used for code indicator-equipped radios on all models except the Europe LHD
model.
+The Europe LHD model has a NATS-linked anti-theft function that renders the code system inop-
erable.
DESCRIPTION
By using a personal 4-digit code known only to the vehicle owner, the possibility of the audio unit being sto-
len is effectively reduced, because without the code the unit can not be activated. When in normal use, the
unit is unlocked and accessible in the usual way.
If however, someone attempts to remove the unit or the battery cable is disconnected, the anti-theft system
activates and the unit ``locks''. The only way it can be unlocked is by entering a personal code number known
only by the owner.
UNLOCKING THE UNIT (How to enter a personal code number)
+If the battery supply to the vehicle is interrupted by accident for some reason, the unit will lock.
To unlock the unit, proceed as follows:
1. Press the power/volume control knob to turn the unit on.
2. ``CODE IN'' is displayed.
3. Input your personal code by pressing the preset buttons (1 to 4).
4. Press the
button.
5. If the entered code number is correct, the radio turns on.
When the code is incorrect
1. If the entered code is incorrect, the unit becomes inoperable for 10 seconds for the ®rst three attempts,
then the code input mode is automatically set (``CODE IN'' is displayed).
2. If the code is incorrect the fourth time, the unit becomes inoperable for 60 minutes and ``
'' is displayed.
After 60 minutes, the code input mode is automatically set (``CODE IN'' is displayed).
NOTE:
If the above is repeated 17 times, the unit will lock and ``LOCKED'' is displayed.
3. After ``LOCKED'' is displayed, radio can be returned to the code input mode only within three attempts as
follows. (Only three attempts are allowed to unlock the unit.)
a. Press the power/volume control knob while pushing both the MOD and TA switches.
b. The unit then returns to the code input mode.
CAUTION:
If the third attempt is unsuccessful, the unit will lock permanently.

NATS Audio Link/LHD
DESCRIPTION
The link with the NATS IMMU implies that the radio can basically only be operated if connected to the match-
ing NATS IMMU to which the radio was initially ®tted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the radio unit is basically
useless since special equipment is required to reset the radio.
Initialisation process for radios that are linked to the NATS IMMU
New radios will be delivered to the factories in the ``NEW'' state, i.e. ready to be linked with the vehicle's NATS.
When the radio in ``NEW'' state is ®rst switched on at the factory, it will start up communication with the vehi-
cle's immobiliser control unit (IMMU) and send a code (the ``Radio Code'') to the IMMU. The IMMU will then
store this code, which is unique to each radio, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will con®rm correct receipt of the radio code to the radio.
Hereafter, the radio will operate as normal.
During the initialisation process, ``NEW'' is displayed on the radio display. Normally though, communication
between Radio and IMMU takes such a short time (300 ms) that the radio seems to switch on directly with-
out showing ``NEW'' on its display.
Normal operation
Each time the radio is switched on afterwards, the radio code will be veri®ed between the radio unit and the
NATS before the radio becomes operational. During the code veri®cation process, ``WAIT'' is shown on the
radio display. Again, the communication takes such a short time (300 ms) that the radio seems to switch on
directly without showing ``WAIT'' on its display.
When the radio is locked
In case of a radio being linked with the vehicle's NATS (immobiliser system), disconnection of the link between
the radio and the IMMU will cause the radio to switch into the lock (``SECURE'') mode in which the radio unit
is fully inoperative. Hence, repair of the radio is basically impossible, unless the radio is reset to the ``NEW''
state for which special decoding equipment is required.
Both Blaupunkt and Clarion have provided their authorized service representatives with so called ``decoder
boxes'' which can bring the radio unit back to the ``NEW'' state, enabling the radio to be switched on after which
repair can be carried out. Subsequently, when the repaired radio is delivered to the ®nal user again, it will be
in the ``NEW'' state as to enable re-linking the radio to the vehicle's immobiliser system. As a result of the
above, repair of the radio can only be done by an authorized Blaupunkt or Clarion representative.
Note:
Radio manufacturer of Nissan Y61 models for Europe is ``Clarion''.
SERVICE PROCEDURE
Item Service procedure Description
Battery disconnection No additional action required. Ð
Radio needs repair Repair needs to be done by authorized represen-
tative of radio manufacturer since radio cannot
be operated unless it is reset to NEW state,
using special decoding equipment.Ð
Replacement of radio by new
partNo additional action required. Radio is delivered in NEW state.
Transferring radio to another
vehicle/replacement of radio
by an ``old'' partRadio needs to be reset to NEW state by autho-
rized representative of radio manufacturer.Ð
Replacement of IMMU by
new partNo additional action required. The new IMMU will be recognized by the radio
since a `blank' code is stored in the memory of
the IMMU. In case the radio recognizes this
`blank' code, it will request for input of the correct
CATS code after which the radio will switch back
to the initialisation process.

EL-174

Item Service procedure Description
Replacement of IMMU by old
partRadio needs to be reset to NEW state by autho-
rized representative of radio manufacturer.If a radio code has already been stored in
memory of the IMMU, the radio cannot be linked
to it. After switching on the radio, it will display
``SECURE'' after 1 minute.
No communication from
IMMU to radio1. If NATS is malfunctioning, check NATS sys-
tem.
2. After NATS is repaired, reset radio to NEW
state by authorized representative of radio
manufacture.After switching on the radio, the radio will display
``SECURE'' after 1 minute. Further use of radios
impossible until communication is established
again, or after radio is reset by authorized repre-
sentative of (radio) manufacturer.
NOTE: Authorized radio manufacturer representatives in Europe are listed in the technical bulletin
TB-EL 96-001 issued by Nissan Europe N.V.
