PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EBS01KC5
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
On Board Diagnostic (OBD) System of EngineEBS01KC6
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
lBe sure to turn the ignition switch OFF and disconnect the battery negative cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MI to light up.
lBe sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
lCertain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector. For description and how to disconnect, refer toPG-75, "
HAR-
NESS CONNECTOR".
lBe sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.
lBe sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel system, etc.
lBe sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.
PrecautionsEBS01KC7
lAlways use a 12 volt battery as power source.
lDo not attempt to disconnect battery cables while engine is
running.
lBefore connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect battery
negative cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
lBefore removing parts, turn ignition switch OFF and then
disconnect battery negative cable.

EC
lDo not disassemble ECM.
lWhen connecting ECM harness connector, fasten it
securely with levers as far as they will go as shown in the
figure.
lWhen 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.
lSecurely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to IC's.
lKeep engine control system harness at least 10cm (4 in)
away from adjacent harness, to prevent engine control sys-
tem malfunctions due to receiving external noise, degraded
operation of IC's, etc.
lKeep engine control system parts and harness dry.
lBefore replacing ECM, perform ECM Terminals and Refer-
ence Value inspection and make sure ECM functions prop-
erly. Refer toEC-52, "
ECM Terminals And Reference Value"
.
lHandle mass air flow sensor carefully to avoid damage.
lDo not disassemble mass air flow sensor.
lDo not clean mass air flow sensor with any type of deter-
gent.
lEven a slight leak in the air intake system can cause seri-
ous incidents.
lDo not shock or jar the camshaft position sensor, crank-
shaft position sensor.

ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
DTC Detection LogicEBS01KCN
When a malfunction is detected, the malfunction (DTC) and freeze frame data are 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 toEC-6, "
INDEX FOR DTC".
Diagnostic Trouble Code (DTC)EBS01KCO
HOW TO READ DTC
The DTC can be read by the following methods.
With CONSULT-II
CONSULT-IIdisplaystheDTCin"SELF-DIAGRESULTS"mode.Example:P0117,P0335,P1268,etc.These
DTCs are prescribed by ISO15031-5.
(CONSULT-II also displays the malfunctioning component or system.)
Without CONSULT-II
The number of blinks of the MI in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0117, 0335, 1260, etc.
lOutput of a DTC indicates a malfunction. However, the Diagnostic Test Mode II does not indicate
whether the malfunction is still occurring or has occurred in the past and has returned to normal.
CONSULT-II can identify malfunction status as shown below. Therefore, using CONSULT-II (if avail-
able) is recommended.
HOW TO ERASE DTC
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”.
4. Touch “ERASE”. (The DTC in the ECM will be erased.)
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
Without CONSULT-II
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once.
2. Wait at least 10 seconds and then turn it ON (engine stopped) again.
3. Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to
EC-29, "
HOW TO SWITCH DIAGNOSTIC TEST MODE".
PBIB2452E

EC-28
ON BOARD DIAGNOSTIC (OBD) SYSTEM
lIf the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.
lThe following data are cleared when the ECM memory is erased.
–Diagnostic trouble codes
–Freeze frame data
–Fuel pump learning value
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures.
Freeze Frame DataEBS01KCP
The ECM records the 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 the DTC data, are called freeze frame data and displayed on CONSULT-II. For
details, seeEC-28, "
Freeze Frame Data".
Only one set of freeze frame data can be stored in the ECM. If freeze frame data is stored in the ECM memory
and another freeze frame data occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clear-
ing the ECM memory are described inEC-27, "
HOW TO ERASE DTC".
NATS (Nissan Anti-theft System)EBS01KCQ
lIf 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 toBL-170, "
NATS(Nissan Anti-Theft System)".
lConfirm no self-diagnostic results of NATS is displayed
before touching "ERASE" in "SELF-DAIG RESULTS" mode
with CONSULT-II.
lWhen 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)EBS01KCR
DESCRIPTION
The MI is located on the combination meter.
1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
lIf the MI does not light up, refer toEC-354, "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
