P Description
The link with the NATS IMMU implies that the AV control unit can basically only be operated if connected to the
matching NATS IMMU to which the AV control unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted, theft of the AV control unit is basi-
cally useless since special equipment is required to reset the AV control unit.
Initialization Process for AV control units That Are Linked to the NATS IMMU
New AV control units will be delivered to the factories in the “NEW” state, i.e. ready to be linked with the vehi-
cle's NATS. When the AV control unit in “NEW” state is first switched on at the factory, it will start up communi-
cation with the vehicle's immobilizer control unit (IMMU) and send a code (the “AV control unit Code”) to the
IMMU. The IMMU will then store this code, which is unique to each AV control unit, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the AV control unit code to the
AV control unit. Hereafter, the AV control unit will operate as normal.
During the initialization process, “NEW” is displayed on the AV control unit display. Normally though, communi-
cation between AV control unit and IMMU takes such a short time (300 ms) that the AV control unit seems to
switch on directly without showing “NEW” on its display.
Normal Operation
Each time the AV control unit is switched on afterwards, the AV control unit code will be verified between the
AV control unit and the NATS before the AV control unit becomes operational. During the code verification pro-
cess, “WAIT” is shown on the AV control unit display. Again, the communication takes such a short time (300
ms) that the AV control unit seems to switch on directly without showing “WAIT” on its display.
When The Radio Is Locked
In case of the AV control unit being linked with the vehicle's NATS (immobilizer system), disconnection of the
link between the AV control unit and the IMMU will cause the AV control unit to switch into the lock
(“SECURE”) mode in which the AV control unit is fully inoperative. Hence, repair of the AV control unit is basi-
cally impossible, unless the AV control 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 AV control unit back to the “NEW” state, enabling the AV control unit to be switched on after which repair
can be performed. Subsequently, when the repaired AV control unit is delivered to the final user again, it will
be in the “NEW” state to enable re-linking the AV control unit to the vehicle's immobilizer system. As a result of
the above, repair of the AV control 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
Item Service procedure Description
Battery disconnection No additional action required. –
Radio needs repair Repair needs to be done by authorized rep-
resentative of radio manufacturer since ra-
dio cannot be operated unless it is reset to
NEW state, using special decoding equip-
ment.–
Replacement of radio by new part No additional action required. Radio is delivered in “NEW” state.
Transferring radio to another vehicle/re-
placement of radio by an old partRadio needs to be reset to NEW state by
authorized representative of radio manu-
facturer.–
Replacement of IMMU Radio needs to be reset to NEW state by
authorized representative of Clarion.After switching on the radio, it will display
“SECURE” after 1 minute.
No communication from IMMU to radio 1. Check NATS system if NATS is mal-
functioning.
2. Reset radio to “NEW” state by autho-
rized representative of Clarion after
NATS is repaired.The radio will display “SECURE” after 1
minute after switching on the radio. Further
use of radio is impossible until communica-
tion is established again, or after radio is re-
set by authorized representative of Clarion.
When initialized between ECM and IMMU. Radio needs to be reset to “NEW” status by
authorized representative of Clarion.It will display “SECURE” after 1 minute after
switching on the radio.

CAN COMMUNICATION SYSTEM
System DescriptionINFOID:0000000001162753
 CAN communication is a multiplex communication system. This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with two communication lines (CAN-H and
CAN-L).
 Control units on the CAN network transmit signals using the CAN communication control circuit. They
receive only necessary signals from other control units to operate various functions.
 CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
System DiagramINFOID:0000000001162754
Each control unit passes an electric current to the termination circuits when transmitting CAN communication
signal. The termination circuits produce an electrical potential difference between CAN-H and CAN-L. CAN
communication system transmits and receives CAN communication signals by the potential difference.

Component Description
Main line CAN communication line between splices
Branch line CAN communication line between splice and a control unit
Splice A point connecting a branch line with a main line
