System Description=NJEL0497Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times
+through 15A fuse (No. 32, located in the fusible link and fuse block)
+to audio unit terminal 9
+to CD auto changer terminal 32.
With the ignition switch in the ACC or ON position, power is supplied
+through 10A fuse [No. 1, located in the fuse block (J/B)]
+to audio unit terminal 3,
+to CD auto changer terminal 36 and
Ground is supplied through the case of the audio unit.
Audio signals are supplied
+through audio unit terminals 7, 10, 11, 12, 13, 14, 15, 16
+to terminals 1 and 2 of front door speaker LH and RH,
+to terminals 1 and 2 of rear door speaker LH and RH and
+to terminals 1 and 2 of pillar tweeter LH and RH (with 6 speakers)
When the navigation system is triggered,
power is supplied
+through navi control unit terminal 46
+to speaker relay terminal 2
Ground is supplied
+through navi control unit terminal 44
+to speaker relay terminal 1
With power and ground supplied, the relay is energized, and then audio signal is interrupted to front door
speaker LH (LHD models) or RH (RHD models), and pillar tweeter LH (LHD models) or RH (RHD models)

NATS AUDIO LINKNJEL0497S01DescriptionNJEL0497S0101The 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 ªNEWº state, i.e. ready to be linked with the vehicle's
NATS. When the audio unit in ªNEWº state is first switched on at the factory, it will start up communication
with the vehicle's immobiliser control unit (IMMU) and send a code (the ªaudio unit Codeº) 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 initialisation process, ªNEWº 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 ªNEWº 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, ªWAITº 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 ªWAITº 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 (ªSECUREº) 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 ªNEWº state for which special decoding equipment is required.
Clarion has provided their authorized service representatives with so called ªdecoder boxesº which can bring
the audio unit back to the ªNEWº state, enabling the audio unit to be switched on after which repair can be

System DescriptionNJEL0480FUNCTIONNJEL0480S01Multi-remote control system has the following function.
+Door lock (and set super lock)
+Door unlock (and release super lock)
+Hazard reminder
LOCK OPERATIONNJEL0480S02To lock door by multi-remote controller, the key switch must be at OFF.
When the LOCK signal is input to time control unit (the antenna of the system is combined with time control
unit)
Then time control unit controls to lock doors and set super lock (models with super lock).
UNLOCK OPERATIONNJEL0480S03When the UNLOCK signal is input to time control unit (the antenna of the system is combined with time con-
trol unit)
Time control unit controls to unlock driver's door and release super lock (models with super lock).
Then, if an unlock signal is sent from the remote controller again within 5 seconds, all other doors will be
unlocked.
HAZARD REMINDERNJEL0480S04When the doors are locked or unlocked by multi-remote controller, supply power to turn lamps hazard reminder
flashes as follows
+Lock operation: Flash once
+Unlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRYNJEL0480S05A maximum of four remote controllers can be entered.
To enter ID code entry, the following signals must be input to the time control unit.
+Ignition switch (ON)
+Signal from remote controller

RHD ModelsNJEL0523S0301By integrating the Navigation System in the vehicle's interior and linking it to the vehicle's immobilizer system,
the possibility of the Navigation unit being stolen is effectively reduced. Each time the Navigation System is
switched on, the Navigation System will start up communication with the vehicle's immobilizer control unit
(IMMU) and verify an identification code. If communication cannot be established, or the verified code is
incorrect, the Navigation System will lock up showing ªANTI-THEFT FUNCTIONº on the Navigation display.
