COMPONENT DESCRIPTION
EGR volume control valve
The EGR volume control valve uses a step motor to control the
flow rate of EGR from exhaust manifold. This motor has four
winding phases. It operates according to the output pulse signal
of the ECM. Two windings are turned ON and OFF in sequence.
Each time an ON pulse is issued, the valve opens or closes,
changing the flow rate. When no change in the flow rate is
needed, the ECM does not issue the pulse signal. A certain
voltage signal is issued so that the valve remains at that particu-
lar opening.

System Description
UNIFIED CONTROL METER
+Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit.
+Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
+Odo/trip meter segment can be checked in diagnosis mode.
+Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
Note:
Turn ignition switch to the ªONº position to operate odo/trip meter.

Segment Check in Diagnosis Mode
DIAGNOSIS FUNCTION
+Odo/trip meter segment can be checked in diagnosis mode.
+Meters/gauges can be checked in diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch to ON and change odo/trip meter to
ªTRIP Aº or ªTRIP Bº.
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter
switch.
4. Confirm that trip meter indicates ª000.0º.
5. Push odo/trip meter switch more than three times within 5
seconds.
6. All odo/trip meter segments should be turned on.
NOTE: If some segments are not turned on, unified meter
control unit with odo/trip meter should be replaced.
At this point, the unified control meter is turned to diagnosis
mode.
7. Push odo/trip meter switch. Indication of each meter/gauge
should be as shown left during pushing odo/trip meter switch
if it is no malfunctioning.
NOTE: It takes about a few seconds for indication of fuel
gauge to become stable.

ID Code Entry Procedure
Activation of the registration mode:
The vehicle must have been unlocked by either the multi-remote controller or a transponder OK signal (TPOK)
from the vehicle's immobilizer.
Preparation: - Make sure all doors unlock.
- Make sure all multi-remote controllers to be registered are available.
- Make sure the batteries of all multi-remote controllers are in a good condition.
- Make sure all transmitting sources are out of the neighbourhood of the vehicle.
- Make sure the battery of the vehicle is in a good condition.b
Switch ignition-switch exactly six times from the ªLOCKº to the ªONº position within 10 seconds and return the
ignition switch to the ªLOCKº position (leaving the key in the ignition switch).b
After 2 seconds the registration mode is activated. The turn signal lamps will flash twice.
OKNG
Proceed with the registration mode.
NOTE
The registration mode is operated when:+The ignition-switch is turned to the ªONº position.
+4 multi remote controllers have been learned.
+No multi-remote controller or ignition switch input is received within 120 sec-
onds.
Registration mode
Press and hold the ªUNLOCKº button of the multi-remote controller.b
Press the ªLOCKº button 3 times.
Release the ªUNLOCKº button.cIf the multi-remote controller
code is registered correctly,
the turn signal lamp will flash

After registration of the requested No. of multi-remote controller(s),
confirm the ID-code(s) by switching the ignition switch to the ªONº
position.cIf the multi-remote controller
registration is performed
correctly, the turn signal lamp
will flash twice.
Take the ignition key out of the ignition switch and confirm the func-
tioning of all multi-remote controllers by locking and unlocking the

C/U INITIALIZATION When replacing any of the following components, C/U initialization is necessary.
[NATS ignition key/IMMU/ECM/Dongle unit]
SELF-DIAG RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialization is performed, all ID previously registered will be erased. So all NATS ignition
keys must be registered again.
The engine cannot be started with an unregistered key. In this case, the system may show ªDIFFER-
ENCE OF KEYº or ªLOCK MODEº as a self-diagnostic result on the CONSULT-II screen.
When initialization is performed (for RHD models), security indicator will flash six times to demon-
strate recognition of dongle unit ID.
