2002 NISSAN TERRANO key

Service Notice or Precautions
FAIL-SAFE
The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs in third gear even with a shift lever position of ª1º, ª2º or ªDº. Cus-
tomer may complain of ªsluggish or poor accelerationº.
When the Fail-Safe operation occurs the next time the key is turned to the ªONº position, the SPORT indica-
tor lamp will blink for about 8 seconds. (For diagnosis, refer to AT-33.)
Fail-Safe may activate without electrical circuit damages if the vehicle is driven under extreme conditions (such
as excessive wheel spins and emergency braking immediately afterwards). In this case, turn the ignition key
ªOFFº for 5 seconds and then ªONº to recover normal shift pattern.
The blinking of the SPORT indicator lamp for about 8 seconds will appear only once and be cleared. The cus-
tomer may resume normal driving conditions by chance.
Always follow the ªWORK FLOWº (Refer to AT-26).
The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate the damage of the vehicle speed sensor or the revolution sensor.
During the next SELF-DIAGNOSIS performed after checking the sensor, no damages will be indicated.

Throttle (accelerator) position switch
Closed throttle position switch (idle position)
ICheck continuity between terminalsq
5andq6.
Accelerator pedal condition Continuity
Released Yes
Depressed No
ITo adjust closed throttle (accelerator) position switch, refer to
EC section (ªBasic Inspectionº, ªTROUBLE DIAGNOSIS Ð
Basic Inspectionº).
Wide open throttle position switch
ICheck continuity between terminalsq
4andq5.
Accelerator pedal condition Continuity
Released No
Depressed Yes
A/T fluid temperature switch
1. Make sure the A/T fluid warning lamp lights when the key is
inserted and turned to ªONº.
2. Make sure the A/T fluid warning lamp goes off when turning the
ignition switch to ªONº.
3. For removal, refer to AT-113.
4. Check resistance between terminalq

ACTIVE TEST PROCEDURE
IWhen conducting Active test, vehicle must be stationary.
IWhen ABS warning lamp stays on, never conduct Active test.
1) Turn ignition switch to the ªLOCKº position.
2) Connect CONSULT-II to Data Link Connector.
3) Start engine.
1) Touch ªSTARTº on CONSULT-II screen.
2) Touch ªABSº.
3) Touch ªACTIVE TESTº.
1) Select active test item by touching screen.
2) Touch ªSTARTº.
Carry out the active test by touching screen key.

TROUBLE DIAGNOSES
CONSULT-II Inspection Procedure (Cont'd)
BR-63

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.
