2001 NISSAN ALMERA N16 audio

Precautions When Working On ABSNJBR0140+Use recommended tyres in combination with ABS.
+Please fit tyres or studded tyres, etc. with the same size.
+If different sizes of tyres, or tyres other than the ones rec-
ommended for use with the ABS, are fitted, stopping dis-
tance will increase and control and stability could deterio-
rate.
+When changing brake pads, please use Nissan genuine
parts.
+When fitting radios etc, do not position the radio itself,
antenna, or antenna cables within an area of about 100
mm (3.94 in) of the control unit.
+When doing any work that requires electro-welding, first
remove the control unit.
+Please take care when taking a power supply for the
audio, lamps etc., not to take this from any ABS-related
harness. (Please refer to the electrical wiring diagrams for
ABS-related harnesses)

+Replace driver air bag module if it has been dropped or
sustained an impact.
+Do not expose the driver air bag module to temperatures
exceeding 90ÉC (194ÉF).
+Do not allow oil, grease or water to come in contact with
the driver air bag module.

3. Set steering wheel in the neutral position.
4. Disconnect horn/audio connector and remove nut.
5. Using steering wheel puller, remove steering wheel. Be care-
ful not to over-tighten puller bolt on steering wheel.
CAUTION:
+Do not tap or bump the steering wheel.
6. Remove steering column cover.

INSTALLATIONNJRS00171. Set the front wheels in the straight-ahead position.
2. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left about 3.5 revo-
lutions from the right end position. Align the two marks (
)or
make sure that the white indicator is visible in the upper part
of the indicator window, with the cable pointed downwards.
CAUTION:
+The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
+Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned up to
about 3.5 turns from the neutral position to both the right
and left.
3. Connect spiral cable connector and tighten with screws. Install
steering column cover.
4. Install steering wheel, aligning with spiral cable pin guides, and
pull spiral cable through.
5. Connect horn/audio connector and engage spiral cable with
pawls in steering wheel. Move driver air bag module connec-
tor away from steering wheel lower lid opening.
6. Tighten nut.

7. Position driver air bag module and tighten with new special
bolts.
8. Connect driver air bag module connector.
9. Install steering switches and lids.
10. Conduct self-diagnosis to ensure entire SRS operates prop-
erly. (Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery cables.
11. Turn steering wheel to the left end and then to the right end
fully to make sure that spiral cable is set in the neutral posi-
tion.
If ªAIR BAGº warning lamp blinks or stays ON (at the user
mode), it shows the spiral cable may be snapped due to its
improper position. Perform self-diagnosis again (use CON-
SULT-II or warning lamp). If a malfunction is detected, replace
the spiral cable with a new one.
12. Perform self-diagnosis again to check that no malfunction is
detected.

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

carried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the
ªNEWº state as to enable re-linking the audio unit to the vehicle's immobiliser system. As a result of the above,
repair of the audio unit can only be done by an authorized Clarion representative.
SPEED DEPENDENT VOLUME CONTROLNJEL0497S02DescriptionNJEL0497S0201If activated, the radio output volume will be automatically adjusted to compensate for increasing driving noises
at higher driving speeds.
The radio receives a speed signal from the vehicle speed sensor (VSS) and selects the output volume.
PERSONAL AUDIO SETTINGSNJEL0497S03DescriptionNJEL0497S0301The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed
dependent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be reg-
istered. During the communication as mentioned under ªNATS audio linkº, the radio will recognize the used
ignition key and select the accompanying settings.
