IIf the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
IErasing the emission-related diagnostic information using CONSULT-II is easier and quicker than
switching the diagnostic test mode using the data link connector.
NATS (Nissan Anti-Theft System)
IIf the security indicator lights up with the ignition switch in
the ªONº position or ªNATS MALFUNCTIONº is displayed
on ªSELF-DIAG RESULTSº screen, perform self-diagnostic
results mode with CONSULT-II using NATS program card.
Refer to ªNATS (Nissan Anti-Theft System)º in EL section.
IConfirm no self-diagnostic results of NATS is displayed
before touching ªERASEº in ªSELF-DIAG RESULTSº mode
with CONSULT-II.
IWhen replacing ECM, initialization of NATS system and
registration of all NATS ignition key IDs must be carried out
with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.
Malfunction Indicator (MI)
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
IIf the MI does not light up, refer to EL section (ªWARNING
LAMPS AND CHIMEº) or see EC-291.
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
If MI illuminates or blinks irregularly after starting engine,
water may have accumulated in fuel filter. Drain water from
fuel filter. Refer to MA section.

System Description
NATS has the following immobiliser functions:
IThis version of NATS has dongle control unit to improve its anti-theft performance (RHD models). Dongle
control unit has its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization
must be carried out.
IWhen malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
Ð When dongle control unit has a malfunction, and the indicator lamp is illuminated, engine can not be
started. However engine can be started only one time when security indicator lamp turns off in about
15 minutes after ignition switch is turned to ON.
ISince only NATS ignition keys, whose ID nos. 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.
IAll of the originally supplied ignition key IDs have been NATS registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NATS compo-
nents.
IThe NATS security indicator (NATS security ind.) blinks when the ignition switch is in ªOFFº or ªACCº
position. Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
IWhen NATS detects trouble, the security indicator lamp lights up as follows.

INATS trouble diagnoses, system initialisation and additional registration of other NATS ignition key IDs
must be carried out using CONSULT-II hardware and CONSULT-II NATS software.
Regarding the procedures of NATS initialisation and NATS ignition key ID registration, refer to CONSULT-II
operation manual, NATS.
IWhen servicing a malfunction of the NATS (indicated by lighting up of security Indicator Lamp) or
registering another NATS ignition key ID no., it may be necessary to re-register original key iden-
tification. Therefore, be sure to receive all keys and the PIN code from vehicle owner.

The maintenance items listed here should be checked periodically, unless otherwise specified.
TiresCheck the pressure with a gauge weekly when at a service station, including the spare,
and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive
wear.Ð
Windshield wiper bladesCheck for cracks or wear if not functioning correctly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
