System Description
Front interior room lamp timer is controlled by smart entrance control unit while interior room lamp switch is
in the ``DOOR'' position.
Smart entrance control unit does not control rear interior room lamp.
TIMER OPERATION
Interior room lamp timer keeps interior room lamp illuminated for about 15 seconds when:
+driver's door is unlocked while key is out of ignition key cylinder,
+key is withdrawn from ignition key cylinder while driver's door is closed, and
+driver's door is opened and then closed while ignition switch is not in the ``ON'' position.
The timer is cancelled, and interior room lamp turns off when:
+driver's door is locked, or
+ignition switch is turned ``ON''.
ON-OFF CONTROL
When the front driver side door, front passenger side door, rear LH door, rear RH door or back door is opened,
interior room lamp turns on.
When driver side door is opened and then closed while ignition switch is not in the ON position, interior room
lamp timer operates. (Timer does not operate when doors other than the driver side door is opened and
closed.)

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.

System Description
OUTLINE
Power door lock system with super lock and key reminder is controlled by super lock control unit. Super lock
has a higher anti-theft performance than conventional power door lock systems.
When super lock is in released condition, lock knob operation locks or unlocks door.
When super lock is in set condition, lock knob operation cannot lock nor unlock door.
NOTE: Super lock function is not applied to back door. (Power door lock only)
OPERATION
Power door lock/unlock and super lock set/release operation by door key cylinder
+With the key inserted into front door key cylinder, turning it to LOCK will lock all doors and set super lock
while all doors are closed or one or more door is open. (Super lock will not be set while key is inserted
in the ignition key cylinder.)
+With the key inserted into front door key cylinder, turning it to UNLOCK will unlock all doors and release
super lock.
Power door lock/unlock and super lock set/release operation by multi-remote controller
+Pressing multi-remote controller LOCK button will lock all doors and set super lock while all doors are
closed and key is not inserted in the ignition key cylinder.
+Pressing multi-remote controller UNLOCK button will unlock all doors and release super lock with key not
inserted in the ignition key cylinder.
Power door lock and super lock release operation (by NATS IMMU signal)
+When the super lock is set, turning ignition key switch to ON will release super lock and unlock all doors.
