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
The on board diagnostic system has the following three functions.

OK >> GO TO 5.
NG >> Change the vehicle for booster.
5.PERFORM DTC CONFIRMATION PROCEDURE AGAIN

2. Touch “ERASE”.
3. PerformEC-203, "
DTC Confirmation Procedure",again.
4. Is DTC P0563 displayed again?
Without CONSULT-II
1. Erase the Diagnostic Test Mode II (Self-diagnostic results) memory. Refer toEC-27
.
2. PerformEC-203, "
DTC Confirmation Procedure",again.
3. Is DTC 0563 displayed again?
Ye s o r N o
Yes >>GOTO6.
No >> GO TO 7.
6.REPLACE ECM
1. Replace ECM.
2. Perform initialization of NATS system and registration of all NATS ignition key IDs. Refer toBL-172, "
ECM
Re-communicating Function".
3. Perform Fuel Pump Learning Value Clearing. Refer toEC-24, "
Fuel Pump Learning Value Clearing".
4. Perform Injector Adjustment Value Registration. Refer toEC-25, "
Injector Adjustment Value Registration".

When a signal is received by BCM, power is supplied
lthrough BCM terminal 42
lto key ring lamp terminal 1
lto front map lamp terminal 1 and
lto room lamp terminal 2.
SWITCH OPERATION
When front map lamp switch is ON, ground is supplied
lto front map lamp terminal 2
lthrough grounds M21, M80 and M83.
When room lamp switch is ON, ground is supplied through room lamp case ground.
ROOM LAMP TIMER OPERATION
When lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer control
(maximum 30 seconds) for interior room lamp and map lamp ON/OFF.
Power is supplied
lthrough 10A fuse [No. 22, located in fuse block (J/B)]
lto key switch terminal 2.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 5.
At the time that driver's door is opened, BCM detects that driver's door is unlocked. It determines that room
lamp timer operation conditions are met, and turns the interior room lamps ON for 30 seconds.
Key is in ignition key cylinder (key switch ON), power is supplied
lthrough key switch terminal 1
lto BCM terminal 5.
When key is removed from key switch (key switch OFF), power supply to BCM terminal 5 is terminated. BCM
detects that key has been removed, determines that room lamp timer conditions are met, and turns the interior
room lamps ON for 30 seconds.
When driver's door opens®closes, and the key is not inserted in the key switch (key switch OFF), BCM ter-
minal 15 changes between 0V (door open)®12V (door closed). The BCM determines that conditions for
room lamp operation are met and turns the room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
lDriver's door is opened [front door switch (driver side)].
lIgnition switch ON.

INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left ON, it will not be turned off even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls interior lamps listed below:
lFront map lamp
lRoom lamp
lKey ring lamp
After lamps turn OFF by the battery saver system, the lamps illuminate again when
lsignal received from keyfob or key cylinder is locked or unlocked,
ldoor is opened or closed,
lkey is removed from ignition key cylinder or inserted in ignition key cylinder.
Interior lamp battery saver control period can be changed by the function setting of CONSULT-II. Refer toLT-

2.BATTERY VOLTAGE INSPECTION
1. Turn ignition switch OFF.
2. Disconnect alternator connector.
3. Turn ignition switch ON.
4. Check voltage between alternator connector terminal 4 and
ground.
Is the inspection result 12V or more?
YES >> Replace alternator. (Alternator power generation error)
NO >> GO TO 3.
3.CHECK FUSE
Check if any of the following fuses in the alternator are blown.
lCheck 15A fuse
OK or NG
OK >> Repair the harnesses.
NG >> If fuse is blownout, be sure to eliminate cause of malfunction befer installing new fuse.
DARK CURRENT INSPECTION
Dark Current: Small current while ignition switch is “OFF”.
NOTE:
lIf battery ground cable is disconnected from battery terminal, a large dark current may not be reproduced.
When battery discharge occurs, never disconnect battery terminal while using ammeter.
lDo not connect CONSULT-II CONVERTER to data link connector when measuring dark current. CON-
SULT-II power should be supplied using AC adapter or internal battery.
1. Attach current measurement probe for CONSULT-II to battery
ground cable. Refer toSC-22, "
OPERATION PROCEDURE OF
CURRENT MEASUREMENT PROBE FOR CONSULT-II".
2. Check that all electrical equipment is turned OFF.
3. Remove key. Close and lock doors. Check that room lamp turns
off.
4. Measure dark current. Is it 50mA or less? Refer toSC-22,
"OPERATION PROCEDURE OF CURRENT MEASUREMENT
PROBE FOR CONSULT-II".
NOTE:
Dark current stable time is different due to equipment and use of
the vehicle. If it is not 50mA or less after leaving for 1 minute, measure dark current again after leaving for
30 minutes or more.
If YES, GO TO 7. If NO, GO TO 5.
5. Remove and install fuses one by one. Search for the fuse that greatly changes dark current.
NOTE:
If dark current is greatly reduced when removing the fuse, and even if dark current is not greatly increased
when installing it again, the fuse circuit may be the cause.
6. Check that dark current changes when moving the suspect circuit harness. If dark current changes, check
harness for short. If dark current does not change, electronic unit in the circuit may not be entering the
energy-saving mode when it turns OFF. If it does not enter the energy-saving mode, replace electronic
unit.
7. No malfunction for alternator and electrical equipment. Electric load may be larger than alternator generat-
ing ability. Check the customer's usage.4 - Ground : 12V or more
