PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00ECJ
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Wiring Diagrams and Trouble Diagnosis EKS00ECK
When you read wiring diagrams, refer to the followings:
Refer to GI-14, "How to Read Wiring Diagrams" in GI section
Refer to PG-2, "POWER SUPPLY ROUTING" for power distribution circuit in PG section
When you perform trouble diagnosis, refer to the followings:
Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in PG section
Refer to GI-23, "How to Perform Efficient Diagnosis for an Electrical Incident" in PG section

WITH CASETTE DECK
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times
through 15A fuse [No. 32, located in the fuse and fusible link box]
to audio unit terminal 6.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 4, located in the fuse block (J/B)]
to audio unit terminal 10.
When audio switch is pushed, audio signals are supplied
through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16
to terminals 1 and 2 of Front door speaker LH and RH
to terminals 1 and 2 of Rear speaker LH and RH
to terminals 1 and 2 of tweeter LH and RH.
When one of audio steering wheel switches is pushed to volume up, seek up, or source, resistance in steering
switch circuit changes depending on which button is pushed. This will change voltage. Power is supplied
from audio unit terminal 26
through combination switch (spiral cable) terminal 4 and 13
to audio steering wheel switch terminal 3.
Ground is supplied
from audio steering wheel switch
through combination switch (spiral cable) terminal 15 and 7
to audio unit terminal 29.
When one of audio steering wheel switches is pushed to volume down, seek down, or special, resistance in
steering switch circuit changes depending on which button is pushed. This will change voltage. Power is sup-
plied
from audio unit terminal 27
through combination switch (spiral cable) terminal 5 and 14
to audio steering wheel switch terminal 4.
Ground is supplied
from audio steering wheel switch
through combination switch (spiral cable) terminal 15 and 7
to audio unit terminal 29.
SPEED SENSITIVE VOLUME SYSTEM
Volume level of this system gone up and down automatically in proportion to the vehicle speed. And the con-
trol level can be selected by the customer.

NATS AUDIO LINK
Description
The link with the NATS IMMU implies that the audio unit can basically only be operated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU
New audio units will be delivered to the factories in the “NEW” state, i.e. ready to be linked with the vehicle's
NATS. When the audio unit in “NEW” state is first switched on at the factory, it will start up communication with
the vehicle's immobilizer control unit (IMMU) and send a code (the “audio unit Code”) to the IMMU. The IMMU
will then store this code, which is unique to each audio unit, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the audio unit code to the audio
unit. Hereafter, the audio unit will operate as normal.
During the initialization process, “NEW” is displayed on the audio unit display. Normally though, communica-
tion between audio unit and IMMU takes such a short time (300 ms) that the audio unit seems to switch on
directly without showing “NEW” on its display.
Normal operation
Each time the audio unit is switched on afterwards, the audio unit code will be verified between the audio unit
and the NATS before the audio unit becomes operational. During the code verification process, “WAIT” is
shown on the audio unit display. Again, the communication takes such a short time (300 ms) that the audio
unit seems to switch on directly without showing “WAIT” on its display.
When the radio is locked
In case of a audio unit being linked with the vehicle's NATS (immobilizer system), disconnection of the link
between the audio unit and the IMMU will cause the audio unit to switch into the lock (“SECURE”) mode in
which the audio unit is fully inoperative. Hence, repair of the audio unit is basically impossible, unless the
audio unit is reset to the “NEW” state for which special decoding equipment is required.
Clarion has provided their authorized service representatives with so called “decoder boxes” which can bring
the audio unit back to the “NEW” state, enabling the audio unit to be switched on after which repair can be car-
ried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the “NEW”
state to enable re-linking the audio unit to the vehicle's immobilizer system. As a result of the above, repair of
the audio unit can only be done by an authorized Clarion representative (when the owner of the vehicle
requests repair and can show personal identification).

Service Procedure
PERSONAL AUDIO SETTILNG
Description
The radio is designed to store several settings (volume, bass, treble, preset stations ) with every NATS
ignition key used. Up to a maximum of 4 NATS keys can be registered. During the communication men-
tioned under “Anti-Theft System”, the radio will recognize the used ignition key and select the accompany-
ing settings.

“SECURE” after 1 minute.
No communication from IMMU to radio 1. If NATS is malfunctioning, check NATS
system.
2. After NATS is repaired, reset radio to
NEW state by authorized representative
of Clarion.After switching on the radio, the radio will
display “SECURE” after 1 minute. Further

tion is established again, or after radio is
reset by authorized representative of Clar-
ion.
