TROUBLE DIAGNOSES
CONSULT Inspection Procedure (Cont'd)
BR-60

DIAGNOSTIC TEST MODE IÐBULB CHECK
In this mode, the MALFUNCTION INDICATOR LAMP on the instrument panel should stay ON. If it remains
OFF, check the bulb. (See the WARNING LAMPS AND CHIME in the EL section. Or see EC-173, 174.)
DIAGNOSTIC TEST MODE IÐMALFUNCTION WARNING
MALFUNCTION
INDICATOR LAMPCondition
ON When the malfunction is detected (Refer to EC-1.) or the ECM's CPU is malfunctioning.
OFF No malfunction
lThese Diagnostic Trouble Code Numbers are clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC
RESULTS).
DIAGNOSTIC TEST MODE IIÐSELF-DIAGNOSTIC RESULTS
In this mode, a diagnostic trouble code is indicated by the number of blinks of the MALFUNCTION INDICA-
TOR LAMP as shown below.
Long (0.6 second) blinking indicates the number of ten digits, and short (0.3 second) blinking indicates the
number of single digits. For example, the malfunction indicator lamp blinks 4 times for about 5 seconds (0.6
sec x 8 times) and then it blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC
``43'' and refers to the malfunction of the throttle position sensor.
In this way, all the detected malfunctions are classified by their diagnostic trouble code numbers. The DTC
``55'' refers to no malfunction. (See DIAGNOSTIC TROUBLE CODE INDEX, refer to page EC-1.)
How to erase diagnostic test mode II (Self-diagnostic results)
The diagnostic trouble code can be erased from the backup memory in the ECM when the diagnostic test
mode is changed from Diagnostic Test Mode II to Diagnostic Test Mode I. (Refer to ``HOW TO SWITCH
DIAGNOSTIC TEST MODES''.)
lIf the battery terminal is disconnected, the diagnostic trouble code will be lost from the backup
memory within 24 hours.
lBe careful not to erase the stored memory before starting trouble diagnoses.
lIf the MIL blinks or ``NATS MALFUNCTION'' is displayed
on ``SELF-DIAG RESULTS'' screen, perform self-diag-
nostic results mode with CONSULT using NATS pro-
gram card (NATS-E940). Refer to EL section.
lConfirm no self-diagnostic results of NATS is displayed
before touching ``ERASE'' in ``SELF-DIAG RESULTS''
mode with CONSULT.
lWhen replacing ECM, initialisation of NATS V2.0 system
and registration of all NATS V2.0 ignition key IDs must
be carried out with CONSULT using NATS program card
(NATS-E940).
Therefore, be sure to receive all keys from vehicle
owner.
Regarding the procedures of NATS initialisation and
NATS ignition key ID registration, refer to CONSULT
operation manual, NATS V2.0.

ID Code Entry Procedure
Note:
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will
erase all ID codes previously entered. Therefore, be sure to receive all remote controllers from the
vehicle owner when any ID code entry is performed.
Enter the identity (ID) code manually when:
lremote controller or control unit is replaced.
lan additional remote controller is activated.
To enter the ID code, follow the procedures below.
PROCEDURE
Close all doors and lock driver side door.
Insert and remove the key from the ignition more than seven times within 10 sec-
onds.
Turn ignition key switch to ``ACC'' position. (The hazard warning lamps will then
flash twice.)
Turn ignition key switch to ``OFF'' and remove the key from the ignition.
Push any button on the new remote controller once. (The hazard warning lamps will
then flash twice.)
At this time, the new ID code is entered and all previous ID memory is com-
pletely erased.
b
Do you want to enter any additional remote controller ID codes?
A maximum four ID codes may be entered. (After 4th ID code is entered, the
registration mode is ended.)
No Yes
ADDITIONAL ID CODE ENTRY
Release the door lock, then lock again
with driver side knob lock switch.
Open driver side door.
END.
After entering the identity (ID) code, check the operation of multi-remote con-
trol system.
NOTE:
lIf you need to activate more than two additional new remote controllers, repeat the procedure
``Additional ID code entry'' for each new remote controller.
lAny ID codes cannot be entered after termination of the ``setting mode''.

Component Parts and Harness Connector
Location
System Description
NATS has the following immobiliser functions:
lSince only NATS ignition keys, whose IDs. have been registered into the ECM and IMMU of NATS, allow
the engine to run, operation of a stolen vehicle without a NATS registered key is prevented by NATS.
That is to say, NATS will immobilize the engine if someone tries to start it without the registered key of
NATS.
lBoth of the originally supplied ignition key IDs have been NATS registered.
If requested by the vehicle owner, a maximum of four key IDs can be registered into the NATS compo-
nents.
lThe NATS security indicator (NATS security ind.) blinks when the ignition switch is in ``OFF'' or ``ACC''
position. Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
lWhen NATS detects trouble, the malfunction indicator lamp (MIL) blinks.
lNATS trouble diagnoses, system initialisation and additional registration of other NATS ignition key IDs
must be carried out using CONSULT hardware and CONSULT NATS software.
When NATS initialisation has been completed, the ID of the inserted ignition key is automatically NATS
registered. Then, if necessary, additional registration of other NATS ignition key IDs can be carried out.
Regarding the procedures of NATS initialisation and NATS ignition key ID registration, refer to CONSULT
operation manual, NATS.
lWhen servicing a malfunction of the NATS (indicated by flashing of Malfunction Indicator Lamp)
or registering another NATS ignition key ID no., it may be necessary to re-register original key
identification. Therefore, be sure to receive all keys from vehicle owner.
