EC


After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.

When 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.

Do 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.

Do not disassemble fuel pump.
If NG, take proper action.

Do not disassemble fuel injector.
If NG, replace fuel injector.

Do not depress accelerator pedal when staring.

Immediately after staring, do not rev up engine unnecessar-
ily.

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 elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standingwave
radio can be kept smaller.
–Be sure to ground the radio to vehicle body.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
IntroductionEBS011UJ
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
The above information can be checked using procedures listed in the table below.
×: Applicable —: Not applicable
*: When DTC and 1st/2nd trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator (MI) on the instrument panel lights up when the same malfunction is detected in
three consecutive trips (Three trip detection logic).
Three Trip Detection Logic and One Trip Detection LogicEBS011UK
On board diagnosis (OBD) system of this vehicle has “Three Trip Detection Logic” and “One Trip Detection
Logic”. For which logic each self-diagnosis corresponds with, refer to EC-973, "
INDEX FOR DTC" .
“Trip” of “Three Trip Detection Logic” means a driving mode in which the self-diagnosis is performed while
driving.
THREE TRIP DETECTION LOGIC
When a malfunction is detected for the first time, 1st trip DTC is stored in the ECM memory. MI does not illumi-
nate at this stage. <1st trip>
When the same malfunction is detected again during the next driving, 2nd trip DTC is stored in the ECM mem-
ory and 1st trip DTC is cleared from the ECM memory. MI does not illuminate at this stage. <2nd trip>
When the same malfunction is detected again at the third driving, DTC and Freeze Frame Data are stored in
the ECM memory and 2nd trip DTC is cleared from the ECM memory. MI illuminates at the same time when
DTC is stored. <3rd trip>
In other words, DTC and Freeze Frame Data are stored and MI illuminates when the same malfunction occurs
in 3 consecutive trips.
This is called “Three Trip Detection Logic”.
ONE TRIP DETECTION LOGIC
When a malfunction is detected for the first time, DTC and Freeze Frame Data are stored in the ECM memory
and MI lights up. This is called “One Trip Detection Logic”. Some self-diagnoses will not illuminate MI when
DTC is stored. (Refer to EC-996, "
Emission-related Diagnostic Information" .) 1st/2nd trip DTC is not stored for
one trip detection logic.

tion, DTC is stored in the ECM memory and MI lights up when the same malfunction is detected during the fol-
lowing consecutive trip (3rd trip).
The procedure for erasing DTC, 1st trip DTC, and 2nd trip DTC from the ECM memory is described in EC-999,
"HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
For malfunctions in which 1st/2nd trip DTC are displayed, Refer to EC-996, "
Emission-related Diagnostic Infor-
mation" .
1st/2nd trip DTC is specified in Service $07 of ISO15031-5. 1st/2nd trip DTC detection occurs without lighting
up MI and therefore does not warn the driver of a malfunction.
When 1st/2nd trip DTC is detected, check, print out or write down, and erase 1st/2nd trip DTC as specified
with step II of Work Flow, refer to EC-1008, "
WORK FLOW" . Then perform DTC Confirmation Procedure or
Overall Function Check to try to duplicate the malfunction. If the malfunction is duplicated, it is necessary to
investigate the cause again.
How to Read DTC and 1st/2nd Trip DTC
DTC and 1st/2nd trip DTC can be read by the following procedures.
With CONSULT-II
With GST
CONSULT-II or GST (Generic Scan Tool): Examples: P0117, P0335, P1260, etc.
These numbers are prescribed by ISO 15031-6.
(CONSULT-II also displays the malfunctioning parts and systems.)
A sample of CONSULT-II display for DTC and 1st/2nd trip DTC is
shown in the figure. DTC and 1st/2nd trip DTC are displayed in the
“SELF-DIAG RESULTS” mode of CONSULT-II.
“TIME” data shows how many times the vehicle was driven after the
last detection of DTC or 1st/2nd trip DTC. When DTC or 1st/2nd trip
DTC has been detected currently, “TIME” becomes “0”.

CONSULT-II displays for DTC and 1st/2nd trip DTC become the
same.

The output of a DTC indicates a malfunction. However, GST
does not indicate whether the malfunction is still occurring or
has occurred in the past and has returned to normal. CONSULT-
II can identify the malfunction status. Therefore the use of CON-
SULT-II (If available) is recommended.
FREEZE FRAME DATA
ECM records driving conditions such as calculated load value, engine coolant temperature, engine speed,
vehicle speed, and intake manifold pressure at the moment a malfunction is detected.
The data stored together with DTC is called Freeze Frame Data, and is displayed on CONSULT-II or GST.
When 1st/2nd trip DTC is detected, Freeze Frame Data is not recorded.
Only a set of Freeze Frame Data can be stored in the ECM memory. When ECM records Freeze Frame Data,
and another Freeze Frame Data is generated after that, the first (original) Freeze Frame Data is not updated in
ECM and it remains.
When the DTC is erased from ECM memory, Freeze Frame Data is erased with DTC. The procedure for eras-
ing DTC is described in EC-999, "
How to Erase DTC" .
HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION
How to Erase DTC
With CONSULT-II
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2. Touch “ENGINE”.
3. Touch “SELF-DIAG RESULTS”.

NATS (Nissan Anti-theft System)EBS01177

If the security indicator lights up with the ignition switch in
the ON position or "NATS MALFUNCTION" is displayed on
"SELF-DIAG RESULTS" screen, perform self-diagnostic
results mode with CONSULT-II using NATS program card.
Refer to NATS (Nissan Anti-Theft System) in BL section.

Confirm no self-diagnostic results of NATS is displayed
before touching "ERASE" in "SELF-DAIG RESULTS" mode
with CONSULT-II.

When replacing ECM, initialization of NATS system and reg-
istration 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 procedure of NATS initialization and NATS ignition key ID registration, refer to CON-
SULT-II operation manual, NATS.
Malfunction Indicator (MI)EBS01F87
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 EC-1699, "MI & DATA LINK
CONNECTORS" .
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.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.

How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-1002, "How to Set Diagnostic
Test Mode II (Self-diagnostic Results)" .
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.
DIAGNOSTIC TEST MODE I — BULB CHECK
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to EC-
1348, "MI & DATA LINK CONNECTORS" .
DIAGNOSTIC TEST MODE I — MALFUNCTION WARNING
These DTC numbers are clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)
DIAGNOSTIC TEST MODE II — SELF-DIAGNOSTIC RESULTS
In this mode, the DTC is indicated by the number of blinks of the MI as shown below. A DTC will be used as an
example for how to read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds
consisting of an ON (0.6-second) - OFF (0.6-second) cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-second ON and 0.3-second OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no mal-
function. (See EC-973, "
INDEX FOR DTC" )
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back up memory in the ECM by depressing accelerator pedal. Refer to EC-
1003, "How to Erase Diagnostic Test Mode II (Self-diagnostic Results)" .

If the battery is disconnected, the DTC will be lost from the backup memory within 24 hours.

Be careful not to erase the stored memory before starting trouble diagnoses.
MI Condition
ON When the malfunction is detected.
OFF No malfunction.
