Without CONSULT-II
1. Turn ignition switch OFF.
2. Check voltage between combination meter (security indicator
lamp) connector M23 terminal 39 and ground.
OK or NG
OK >> Security indicator lamp is OK.
NG >> GO TO 2.
2.CHECK SECURITY INDICATOR LAMP POWER SUPPLY CIRCUIT
1. Disconnect combination meter connector.
2. Check voltage between combination meter connector M23 ter-
minal 3 and ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open or short between fuse and com-
bination meter.

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.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006DL
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.
Precautions for Brake SystemEFS005SD
lClean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed
on painted areas, wash it away with water immediately.
lTo clean or wash all parts of master cylinder, disc brake caliper, wheel cylinder, use new brake fluid.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse a flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
lAlways tighten brake lines to the specified torque when install-
ing.
lBefore working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
the battery cables.
lBurnish the new brake surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer toBR-29, "
BRAKE BURNISHING PROCEDURE".
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.SBR820BA

CAUTION:
lWhile bleeding, pay attention to master cylinder fluid level.
lBefore working, disconnect electrical connector of ABS actuator and electric unit (control unit) or
the battery cable from the negative terminal.
LHD MODEL
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.
3. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
4. Repeat steps 3, 4 until no more air comes out.
5. Tighten bleed valve to specified torque. Refer toBR-24, "
Components"(front disc brake),BR-30, "Com-
ponents"(rear drum brake).
6. From the steps 1 to 5 above, with master cylinder reservoir tank filled at least half way, bleed air from the
front left, rear left, and front right brake, in that order.
