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, the stolen 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 initialization process, ªNEWº is displayed on the audio unit display. Normally though, communica-
tion between audio unit and IMMU takes such a short time 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 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 (immobiliser 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.

Service instruction
ItemRadio linked with IMMU and/or SECU
Battery disconnection No additional action required
Radio needs repair Repair needs to be done by authorised 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 Radio is delivered in NEW state. If possible, the radio will automatically link up with the immobiliser system. If this appears not possible, CATS code needs to be manually input
Transferring radio to another vehicle/
replacement of radio by an ªoldº part Radio needs to be reset to NEW state by authorised representative of radio manufac-
turer
Replacement of IMMU by new part Radio will request for CATS code input prior to establishing the link with the IMMU
Replacement of IMMU by old part If a radio code has already been stored in memory of the IMMU, the radio cannot be linked to it. After switching on the radio, it will display ªSECUREº after 1 minute. Opera-
tion can only be established after resetting the ratio by an authorised representative of
radio manufacturer
CATS code input procedure
1. Radio displays ªCODE INº after the power is switched ON.
2. Enter CATS code (4-digits) by pressing the preset buttons (using 1 to 4).Press the preset buttons for the necessary amount of times for the number of each digits.
e.g. CATS code is ª5432º
Press No. 1 preset button for 5 times
Press No. 2 preset button for 4 times
Press No. 3 preset button for 3 times
Press No. 4 preset button for 2 times
3. Press the
button.
4. If the code is OK, the radio will power ON. If the code is NG, the radio will be locked up as below. After the lock up, the radio will display ªCODE INº
again.
1st to 3rd attempt: The radio will be locked for 10 seconds after each attempt
4th to 20th attempt: The radio will be locked for 60 minutes after each attempt
Over 20th attempt: The radio will be locked completely
SPEED DEPENDENT VOLUME CONTROL
Description
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 out-
put volume.

Trouble Diagnoses
If doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains a valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and allow
key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.

Trouble Diagnosis
The Time Control Unit includes software to help during development testing, manufacturing and service.
It allows the technician to put it into Diagnostic Mode. In this mode, all switch inputs can be tested for conti-
nuity and if so equipped, alarm triggers identified.
When the time control unit is in Diagnostic Mode, the control unit tests the component and indicate the result
by the hazard lamp flashing.
On vehicles with a theft warning system, the TCU will first indicate the source of the last three alarm triggers
by flashing the hazard lamp. (Refer to ªTHEFT WARNING SYSTEMº, EL-243.)
ESTART
NOTE: Before entering diagnostic mode, make sure the vehicle is fully unlocked, the ignition is switched off and the hazard switch is off.
Press the rear defogger switch exactly 6 times within 10 seconds.
FNG The hazard lamp flash at 3 Hz for 1 second to confirm step I.
OK
Within 10 seconds after confirmation of step I, turn the ignition ON.
FNG The hazard lamp flash at 3 Hz for 1 second to confirm step II.
OK
Within 10 seconds after confirmation of step II, turn the ignition off,
remove the ignition key and press the rear defogger switch for at least 5 seconds.
NGThe hazard lamp flash at 3 Hz for 3 seconds to confirm diagnostic mode is entered.
