4.PERFORM INITIALIZATION WITH CONSULT-II AGAIN
1. Replace BCM.
2. Perform initialization with CONSULT-II.
For initialization, refer to “CONSULT-II Operation Manual
NATS”.
NOTE:
If the initialization is not completed or malfunctions, CONSULT-II
shows the message on the screen.
Can the system be initialized?
Yes >>SystemisOK.(BCMismalfunctioning.)
No >> ECM is malfunctioning.
lReplace ECM.
lPerform initialization with CONSULT-II
lFor initialization, refer to “CONSULT-II Operation
Manual NATS”
Removal and Installation of NATS Antenna AmpEIS00DB7
REMOVAL
CAUTION:
Before servicing SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
1. Remove the cluster lid A. Refer toIP-10, "
INSTRUMENT PANEL ASSEMBLY".
2. Disconnect the NATS antenna amp connector, remove the
screw and antenna amp.
INSTALLATION
Install in the reverse order of removal.
NOTE:
lIf NATS antenna amp. is not installed correctly, NATS system will not operate properly and SELF-
DIAG RESULTS on CONSULT-II screen will show “LOCK MODE” or “CHAIN OF IMMU-KEY”.
lInitialization is not necessary only when NATS antenna amp. is replaced with a new one.

1.CHECK CHIME OPERATION
1. Select “BUZZER” of “BCM”.
2. Perform “LIGHT WARN ALM”, “IGN KEY WARN ALM” of
“ACTIVE TEST”.
Does chime sound?
YES >> Check battery power supply of combination meter. Refer
toDI-19, "
Power Supply and Ground Circuit Inspec-
tion"in combination meter.
NO >> GO TO 2.
2.CHECK COMBINATION METER SIGNAL
1. Select “METER”.
2. With “DATA MONITOR”, confirm “BUZZER” under the condition
of buzzer input. (Turn signal lamp operate, etc.)
OK or NG
OK >> Replace combination meter.
NG >> Replace BCM. Refer toBCS-17, "
Removal and Installa-
tion of BCM".
Symptom Diagnoses/Service procedure
All warning chime systems do not activate. PerformDI-61, "
Meter Buzzer Circuit Inspection".

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
The on board diagnostic system has the following three functions.

OK or NG
OK >> GO TO 4.
NG >> Reconnect jumper cables properly.
4.CHECK BATTERY FOR BOOSTER
Check that the battery for the booster is a 12V battery.
OK or NG
OK >> GO TO 5.
NG >> Change the vehicle for booster.
5.PERFORM DTC CONFIRMATION PROCEDURE AGAIN
With CONSULT-II
1. Select “SELF DIAG RESULTS” mode with CONSULT-II.
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".
