I
through 10A fuse [No. 10, located in the fuse block (J/B)]
I
to the rear window defogger relay terminal 1 and
I
to smart entrance control unit terminal 29.
With the ignition switch in the ACC or ON position, power is supplied
I
through 10A fuse [No. 1, located in the fuse block (J/B)]
I

Ground is supplied
I
to terminal 1 of the multi-function switch (rear window defogger switch)
I
through body grounds M28, M48, M109 (QG engine) or F51 (YD engine).
When the rear defogger switch is turned ON, ground is supplied
I
through terminal 9 of the multi-function switch (rear defogger switch)
I
to smart entrance control unit terminal 22.
Terminal 31 of smart entrance control unit then supplies ground to the rear window defogger relay terminal 2.
With power and ground supplied, the rear window defogger relay is energized.

REPAIRING PROCEDURE
NLEL0078S02
1.
Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2.
Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3.
Place ruler on glass along broken line. Deposit conductive sil-
ver composition on break with drawing pen. Slightly overlap
existing heat wire on both sides [preferably 5 mm (0.20 in)] of
the break.
SEL012D
4.
After repair has been completed, check repaired wire for con-
tinuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
SEL013D
5.
Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area
and hot air outlet. If a heat gun is not available, let the repaired
area dry for 24 hours.

Navigation system of guidance voice will be sounded.
NATS AUDIO LINK
NLEL0542S05
Description
NLEL0542S0501
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
I
Perform initialization with CONSULT-II
I
For initialization, refer to “CONSULT-II operation manual NATS”.
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.
When the radio is locked
When NATS link problems occur “SECURE” message will be displayed in three ways indicating three differ-
ent NATS link malfunctions.
“SECURE” on a red background indicates that there is a malfunction in the link between NAVI control unit and
audio, suggesting that there is either a Navigation system malfunction or the NAVI control unit has previously
AUDIO
System Description
EL-186
been fitted in another vehicle.
“SECURE” on a green background indicates that there is a malfunction in the link between NATS IMMU and
audio, suggesting that there is an audio malfunction or the audio unit has previously been fitted in another
vehicle.
“SECURE” on a yellow background indicates that the transponder (NATS key) is not working correctly or it
has previously been fitted in another vehicle.
When a “SECURE” message (of any type) is displayed, it can be cleared by re-initializing the NATS system
using CONSULT-II and the associated Immobilizer PIN code (there is no need to return the audio to a Clarion
service centre). If re-initializing fails to clear a “SECURE” message then the component (identified by back-
ground color) is malfunction and should be replaced.
NOTE:
When the “SECURE” is displayed on VFD display or audio unit, the communication of IMMU and radio, radio
unit or transponder has malfunction.
Service Procedure
NLEL0542S0502
Item
Service procedure
Description
Battery disconnection
No additional action required.
—
Radio needs repair
Repair needs to be done by authorized
representative of radio manufacturer since
radio cannot be operated unless it is reset
to NEW state, using special decoding
equipment.
—
Replacement of radio by new part
No additional action required.
Radio is delivered in NEW state.
Transferring radio to another vehicle/
replacement of radio by an “old” part
Radio needs to be reset by using CON-
SULT-II and the associated immobilizer
PIN code (there is no need to return the
audio or NAVI units to a Clarion service
center).
—
Replacement of IMMU
The communication between IMMU and
radio need to be reset by using CON-
SULT-II and the associated immobilizer
PIN code.
After switching on the radio, it will display
“SECURE” on a green background.
No communication from IMMU to radio
1. If NATS is malfunctioning, check NATS
system.
2. After NATS is repaired, reset radio to
“SECURE” on a green background
state by using CONSULT-II and the
associated immobilizer PIN code (there
is no need to return the audio to a
Clarion service center).
After switching on the radio, the display
unit will display “SECURE” on a green
background. Further use of radio is
impossible until communication is estab-
lished again, or after radio is reset by
using CONSULT-II and the associated
Immobilizer PIN code (there is no need to
return the audio to a Clarion service cen-
tre).
SPEED DEPENDENT VOLUME CONTROL
NLEL0542S06
Description
NLEL0542S0601
If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds.
The radio receives a speed signal from the combination meter and selects the output volume.
PERSONAL AUDIO SETTINGS
NLEL0542S07
Description
NLEL0542S0701
The 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 mentioned under “Anti-Theft System”, the radio will recognize the used
ignition key and select the accompanying settings.
