POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
Ithrough 10A fuse [No. 16, located in the fuse block (J/B)]
I to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 12, located in the fuse block (J/B)]
I to combination meter terminal 28.
Ground is supplied
I through body grounds F36, F47 (LHD models) or M33, M754 (RHD models)
I to combination meter terminal 29.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
Thermal transmitter provides a engine coolant temperature signal to combination meter for water temperature
gauge.
TACHOMETER
The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed sig-
nal to combination meter for tachometer.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
Ifrom body grounds B10 and B18
I through terminal 3 of the fuel level sensor unit and
I through terminal 2 (TD27Ti engine) or 1 (ZD30DDTi engine) of the fuel level sensor unit
I to combination meter terminal 13 for the fuel gauge.
SPEEDOMETER
The combination meter receives a signal from vehicle speed sensor. The speedometer converts the signal into
the vehicle speed displayed.
AMBIENT TEMPERATURE GAUGE
Ambient temperature sensor provides the signal for ambient temperature to combination meter.

Combination Meter Self-Diagnosis
PERFORMING SELF-DIAGNOSIS MODE
1. Turn the ignition switch to the ªLOCKº position.
2. Press both reset buttons on the combination meter and keep them depressed.
3. Turn the ignition switch to the ªONº position, while keeping the reset buttons pressed.
4. Release both reset buttons within 5 seconds after ignition switch is ªONº, then self-diagnosis will start. Thesequence (A to I) is activated by press the either reset buttons.
NOTE:
If either reset button is not pressed for 20 seconds at each step or if the ignition switch is turned OFF, the
self-diagnosis mode is exited.

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.
