2002 NISSAN TERRANO key battery

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.

How to Erase DTC (Without CONSULT-II)
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-323.)
The emission related diagnostic information in the ECM can be erased by changing the diagnostic test mode.
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.
Malfunction Indicator (MI)
1. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is a bulb check.
IIf the malfunction indicator does not light up, refer to EL sec-
tion (ªWARNING LAMPS/WIRING DIAGRAMº) or see MI &
DATA LINK CONNECTORS.
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an engine system malfunction.
If MI illuminates or flashes irregularly after starting engine,
water may have accumulated in fuel filter. Drain water from
fuel filter.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.
Diagnostic

circuit, etc.).
If the MI does not come on, check MI circuit. (See EC-452.)

malfunction, the MI will light up to inform the driver that a mal-
function has been detected.

DIAGNOSTIC TEST MODE IÐBULB CHECK
In this mode, the MALFUNCTION INDICATOR on the instrument panel should stay ON. If it remains OFF,
check the bulb. Refer to EL section (ªWARNING LAMPS/WIRING DIAGRAMº) or see EC-452.
DIAGNOSTIC TEST MODE IÐMALFUNCTION WARNING
MI Condition
ON When a malfunction is detected or the ECM's CPU is malfunctioning.
OFF No malfunction.
IThese Diagnostic Trouble Code Numbers are clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC
RESULTS).
DIAGNOSTIC TEST MODE IIÐSELF-DIAGNOSTIC RESULTS
In this mode, DTC is indicated by the number of blinks of the MI as shown below.
Long (0.6 second) blinking indicates the two LH digits of number and short (0.3 second) blinking indicates the
two RH digits of number. For example, the MI blinks 10 times for 6 seconds (0.6 sec x 10 times) and then it
blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC ª1003º.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC ª0505º refers to no
malfunction. (See TROUBLE DIAGNOSIS Ð INDEX, EC-293.)
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 repeating consecutively twice. (Refer to
ªHOW TO SWITCH DIAGNOSTIC TEST MODESº on previous page.)
IIf the battery terminal is disconnected, the diagnostic trouble code will be lost from the backup
memory within 24 hours.
IBe careful not to erase the stored memory before starting trouble diagnoses.
IIf the MI flashes or ªNATS MALFUNCTIONº is displayed on ªSELF-DIAG RESULTSº screen, perform
self-diagnostic results mode with CONSULT-II using NATS program card (NATS-E940). Refer to 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, initialisation of NATS system and registration of all NATS ignition key IDs
must be carried out with CONSULT-II using NATS program card (NATS-E940).
Therefore, be sure to receive all keys from vehicle owner.

Trouble Diagnoses
If doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.
Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains a
valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and allow
key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.
