TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

System DescriptionEIS00DAP
NATS (Nissan Anti-Theft System) has the following immobilizer functions:
lSince only NATS ignition keys, whose ID No. s have been registered into the ECM and IMMU of NATS,
allow the engine to run, a vehicle operation without a registered key in NATS is prevented by NATS.
That is to say, NATS will immobilize the engine if someone tries to start it without the registered key of
NATS.
lThis version of NATS has dongle unit to improve its anti-theft performance (RHD models). Dongle unit has
its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization must be per-
formed.
lWhen malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
–When dongle unit has a malfunction and the indicator lamp is illuminated, engine cannot be started. How-
ever engine can be started only one time when security indicator lamp turns off in about 15 minutes after
ignition switch is turned to ON.
lAll of the originally supplied ignition key IDs have been NATS registered in NATS.
If the vehicle owner requests, a maximum of four key IDs can be registered into the NATS components.
lThe security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, NATS
warns outsiders that the vehicle is equipped with the anti-theft system.
lWhen NATS detects malfunction, the security indicator lamp lights up as follows.
lNATS trouble diagnoses, system initialization and additional registration of other NATS ignition key IDs
must be performed using CONSULT-II hardware and CONSULT-II NATS software.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
lWhen servicing a malfunction of the NATS (indicated by lighting up of Security Indicator Lamp) or
registering another NATS ignition key ID no., it may be necessary to re-register original key identi-
fication. Therefore, be sure to receive ALL KEYS from vehicle owner.

System DiagramEFS005TJ
FunctionsEFS005TK
ABS
lThe Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheels lock. Maneuverability is also
improved for avoiding obstacles.
lElectrical system diagnosis by CONSULT-II is available.
EBD
lElectronic Brake Distributor is a function that detects subtle slippages between the front and rear tyre dur-
ing braking, and it improves handling stability by electrically controlling the brake fluid pressure which
results in reduced rear tyre slippage.
lElectrical system diagnosis by CONSULT-II is available.
Operation That Is Not “System Error”EFS005TL
ABS
lWhen starting engine or just after starting vehicle, brake pedal may vibrate or the motor operating noise
may be heard from engine room. This is a normal states of the operation check.
lDuring ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionEFS005TM
ABS, EBD SYSTEM
In case of electrical malfunction with ABS, ABS warning lamp will turn on. In case of electrical incidents with
EBD, brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of following
conditions of Fail-Safe function.
1. For ABS malfunction, only EBD is activated and condition of vehicle is same condition of vehicles without
ABS system.
NOTE:
ABS self-diagnosis sound may be heard.That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
2. For EBD malfunction, EBD and ABS become inoperative, and condition of vehicle is same as condition of
vehicles without ABS, EBD system.

PRECAUTIONS FOR DIAGNOSIS
lBefore performing diagnosis, always read precautions. Refer toBRC-17, "CONSULT- II Functions".
lAfter diagnosis is finished, be sure to erase memory. Refer toBRC-18, "ERASE MEMORY".
lWhen checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.
lFor intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.
lIf a circuit tester is used for check, be careful not to forcibly extend any connector terminal.
lABS system electrically controls brake operation and engine output. Following symptoms may be caused
by normal operations:
Basic InspectionEFS005TY
BASIC INSPECTION 1 BRAKE FLUID LEVEL, LEAKS, AND BRAKE PADS
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake tube and around ABS actuator and electric unit (control unit) for leaks. If leakage or seepage
is found, check the following items.
lIf ABS actuator and electric unit (control unit) connection is loose, tighten brake tube to the specified
torque and re-conduct the leak inspection to make sure there are no leakage.
lIf there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leakage.
lIf there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm than there
is on leakage.
lIf there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).
CAUTION:
ABS actuator and electric unit (control unit) body cannot be disassembled.
3. Check brake pad degree of wear. Refer toBR-24, "
PAD WEAR INSPECTION"in “Front Disc Brake” and
BR-32, "
Lining Thickness Inspection"in “Rear Drum Brake”.
BASIC INSPECTION 2 POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cable and ground connection are not loose. In addition, check the
battery voltage to make sure it has not dropped and alternator is normal.
Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ABS actuator and electric unit (control unit). Slight
noise may occur during ABS operation.
Normal
Just after engine starts, motor operating noise may be heard. This is a normal
status of the system operation check.
System operation check noiseWhen engine starts, slight “click” noise may be heard from engine compart-
ment. This is normal and is part of system operation check.Normal
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads
or gravel roads, the stopping distance is sometimes longer for vehicles
equipped with ABS. Therefore, when driving on such roads, drive at a suffi-
ciently reduced speed to be safe.Normal
