due to receiving external noise, degraded operation of ICs,
etc.
IKeep ECM parts and harnesses dry.
IBefore replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-69.
IIf MI (MIL) illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
IAfter performing each TROUBLE DIAGNOSIS, perform
ªDTC Confirmation Procedureº or ªOverall Function
Checkº.
The DTC should not be displayed in the ªDTC Confirmation
Procedureº if the repair is completed. The ªOverall Func-
tion Checkº should be a good result if the repair is com-
pleted.
IWhen measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
IDo not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the
ECM's transistor. Use a ground other than ECM terminals,
such as the ground.

Air Bleeding
Pump the priming pump to bleed air.
IWhen air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop operation at that
time.
IIf it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. Then, perform the operation
described above, and make sure that fuel comes out. (Use
a pan, etc. so as not to spill fuel. Do not let fuel get on
engine and other parts.) After that, connect the hose, and
then bleed air again.

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
