Self-diagnosis
FUNCTION
+When a problem occurs in the ABS, the warning lamp on the
instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData Link Connectorº. The location of the mal-
function is indicated by the warning lamp flashing.
+While DIFF-LOCK is on, anti-lock warning light flashes.
SELF-DIAGNOSIS PROCEDURE
Turn off DIFF-LOCK switch.
Drive vehicle over 30 km/h (19 MPH) for
at least one minute.
Turn ignition switch ªOFFº.
Ground terminal ª9º of ªData link connec-
torº with a suitable harness.
Turn ignition switch ªONº while ground-
ing terminal ª9º.
Do not depress brake pedal.
After 3.0 seconds, the warning lamp
starts flashing to indicate the malfunction
code No. (See NOTE.)
Verify the location of the malfunction
with the malfunction code chart. Refer to
the original Service Manual. Then make
the necessary repairs following the diag-
nostic procedures.
After the malfunctions are repaired,
erase the malfunction codes stored in
the control unit. Refer to the original Ser-
vice Manual.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have
been erased.
Disconnect the check terminal from the
ground. The self-diagnostic results mode
is now complete.NOTE: The indication terminates
after five minutes.
However, when the ignition
switch is turned from
ªOFFº to ªONº, the indica-
tion starts flashing again.

TROUBLE DIAGNOSES

Precautions
+Always use a 12 volt battery as power source.
+Do not attempt to disconnect battery cable while engine
is running.
+Before connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect
negative battery terminal. Failure to do so may damage
the ECM because battery voltage is applied to ECM even
if ignition switch is turned off.
+Before removing parts, turn off ignition switch and then
disconnect battery ground cable.
+Do not disassemble ECM.
+If a battery terminal is disconnected, the memory will
return to the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is
disconnected. However, this is not an indication of a
problem. Do not replace parts because of a slight varia-
tion.
+When ECM is removed for inspection, make sure to
ground the ECM mainframe.
+When connecting ECM harness connector, tighten
securing bolt until the gap between the orange indica-
tors disappears.
: 3.0 - 5.0 Nzm (0.3 - 0.5 kg-m, 26 - 43 in-lb)
+When connecting or disconnecting pin connectors into
or from ECM, take care not to damage pin terminals
(bend or break).
Make sure that there are not any bends or breaks on
ECM pin terminal, when connecting pin connectors.
+Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in the circuit, thus resulting in dam-
age to ICs.
+Keep ECM harness at least 10 cm (3.9 in) away from
adjacent harnesses, to prevent an ECM system malfunc-

+Do not disconnect pump harness connector with engine
running.
+Do not disassemble electronic fuel injection pump.
If NG, take proper action.
+Do not disassemble injection nozzle.
If NG, replace injection nozzle.
+Even a slight leak in the air intake system can cause
serious problems.
+Do not shock or jar the crankshaft position sensor
(TDC).
+Do not depress accelerator pedal when starting.
+Immediately after starting, do not rev up engine unnec-
essarily.
+Do not rev up engine just prior to shutdown.
+When installing C.B. ham radio or a mobile phone, be
sure to observe the following as it may adversely affect
electronic control systems depending on its installation
location.
1) Keep the antenna as far as possible away from the ECM.
2) Keep the antenna feeder line more than 20 cm (7.9 in)
away from the harness of electronic controls.
Do not let them run parallel for a long distance.
3) Adjust the antenna and feeder line so that the standing-
wave ratio can be kept smaller.
4) Be sure to ground the radio to vehicle body.

DTC and MI Detection Logic
When a malfunction is detected, the malfunction (DTC) is stored in the ECM memory.
The MI will light up each time the ECM detects malfunction. For diagnostic items causing the MI to light up,
refer to ªTROUBLE DIAGNOSIS Ð INDEXº, EC-1006.
Diagnostic Trouble Code (DTC)
HOW TO READ DTC
The DTC can be read by the following methods.
Without CONSULT-II
ECM displays the DTC by a set of four digit numbers with MI illumination in the diagnostic test mode II
(Self-diagnostic results). Example: 0102, 0407, 1004, etc.
With CONSULT-II
CONSULT-II displays the DTC in ªSELF-DIAG RESULTSº mode. Examples: ªCRANK POS SEN (TDC)º, etc.
+Output of the trouble code means that the indicated circuit has a malfunction. However, in the
Mode II it does not indicate whether the malfunction is still occurring or occurred in the past and
returned to normal.
CONSULT-II can identify them. Therefore, using CONSULT-II (if available) is recommended.
HOW TO ERASE DTC
How to erase DTC (
With 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. Touch ªENGINEº.
3. Touch ªSELF-DIAG RESULTSº.
4. Touch ªERASEº. (The DTC in the ECM will be erased.)
The emission related diagnostic information in the ECM can be erased by selecting ªERASEº in the ªSELF-
DIAG RESULTSº mode with CONSULT-II.

2. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See
EC-1035.)
The emission related diagnostic information in the ECM can be erased by changing the diagnostic test mode.
+If the battery is disconnected, the emission-related diagnostic information will be lost after
approx. 24 hours.
+Erasing 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)
+If the security indicator lights up with the ignition switch
in the ªONº position or ªNATS MALFUNCTIONº is dis-
played on ªSELF-DIAG RESULTSº screen, perform self-
diagnostic results mode with CONSULT-II using NATS
program card. Refer to ªNATS (Nissan Anti-Theft Sys-
tem)º in EL section.
+Confirm no self-diagnostic results of NATS is displayed
before touching ªERASEº in ªSELF-DIAG RESULTSº
mode with CONSULT-II.
+When 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 CON-
SULT-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
without the engine running. This is a bulb check.
+If the MI does not light up, refer to EL section (ªWARNING
LAMPS AND CHIMEº) or see EC-1276.
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.
