PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006L7
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WAR NIN G:
To 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.
Improper 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.
Do 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 System EFS006L8
CAUTION:
Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" for recommended brake fluid.
Never reuse drained brake fluid.
Be 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.
To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.
Use flare nut wrench when removing and installing brake
tube.
If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
Turn the ignition switch OFF and remove the connector of
the ABS actuator and electric unit (control unit) or the bat-
tery terminal before performing the work.
Always torque brake lines when installing.
Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage. Refer to BR-29, "
Brake Burnishing Procedure" .
WAR NIN G:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions When Using CONSULT-IIEFS006L9
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
If YES, GO TO 2.
If NO, GO TO 5.

TROUBLE DIAGNOSES FOR SYMPTOMSPFP:99999
ABS Works FrequentlyEFS006LW
1. CHECK WARNING LAMP ACTIVATION
Make sure warning lamp remains off while driving.
OK or NG
OK >> GO TO 2.
NG >> Carry out self-diagnosis. Refer to BRC-20, "
SELF-DIAGNOSIS" .
2. CHECK WHEEL SENSORS
Check the following.
Wheel sensor mounting for looseness
Wheel sensors for physical damage
Wheel sensor connectors for terminal damage or loose connections
Sensor rotor and mount for physical damage
OK or NG
OK >> GO TO 3.
NG >> Repair or replace as necessary.
3. CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FA X -5 , "
FRONT WHEEL BEARING INSPECTION" or RAX-4,
"REAR WHEEL BEARING INSPECTION" .
OK or NG
OK >> GO TO 4.
NG >> Repair as necessary.
4. CHECK BRAKE FLUID PRESSURE
Check brake fluid pressure distribution.
Refer to BRC-17, "
Basic Inspection" .
Is brake fluid pressure distribution normal?
YES >> Inspection End.
NO >> Perform Basic Inspection. Refer to BRC-17, "
Basic Inspection" .

Unexpected Pedal ActionEFS006LX
1. CHECK WARNING LAMP ACTIVATION
Make sure warning lamp remains off while driving.
OK or NG
OK >> GO TO 2.
NG >> Carry out self-diagnosis. Refer to BRC-20, "
SELF-DIAGNOSIS" .
2. CHECK BRAKE PEDAL STROKE
Check brake pedal stroke.
Is brake pedal stroke excessive?
YES >> Perform Basic Inspection. Refer to BRC-17, "Basic
Inspection" .
NO >> GO TO 3.
3. CHECK CONNECTOR AND BRAKING PERFORMANCE
1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check brake operation.
NOTE:
Stopping distance may be longer than vehicles without ABS when road condition is slippery.
Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
4, "SYSTEM DESCRIPTION" .
OK or NG
OK >> GO TO 4.
NG >> Perform Basic Inspection. Refer to BRC-17, "
Basic Inspection" .
4. CHECK WHEEL SENSORS
Check the following.
Wheel sensor mounting for looseness
Wheel sensors for physical damage
Wheel sensor connectors for terminal damage or loose connections
Sensor rotor and mount for physical damage
OK or NG
OK >> Check ABS actuator and electric unit (control unit) connector terminals for deformation, discon-
nection, looseness or damage. Reconnect ABS actuator and electric unit (control unit) harness
connector. Then retest.
NG >> Repair or replace as necessary.

2. Without disassembling the hydraulic lines, remove the torque member bolts using power tool. Then repo-
sition the torque member and brake caliper assembly aside with wire. Refer to BR-24, "
FRONT DISC
BRAKE" .
CAUTION:
Do not depress brake pedal while brake caliper is removed.
3. Put alignment marks on disc rotor and wheel hub and bearing
assembly, then remove disc rotor.
4. Remove wheel sensor from steering knuckle. Refer to BRC-33, "
WHEEL SENSORS" .
CAUTION:
Do not pull on wheel sensor harness.
5. Loosen steering outer socket (1) nut.
6. Remove steering outer socket (1) from steering knuckle (2) so
as not to damage ball joint (3) boot using ball joint remover or
suitable tool.
CAUTION:
Temporarily leave the outer socket nut installed to prevent
damage to threads and to prevent the ball joint remover or
suitable tool from suddenly coming off.
7. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
8. Remove cotter pin, then loosen hub lock nut using power tool.
CAUTION:
Temporarily leave the hub lock nut installed to prevent damage to threads.
9. Separate the drive shaft from the wheel hub and bearing assem-
bly by lightly tapping the end of the drive shaft using a hammer
or suitable tool, and then remove hub lock nut.
NOTE:
Use a suitable puller if wheel hub and bearing assembly and
drive shaft cannot be separated after performing the above pro-
cedure.
10. Remove the drive shaft from the wheel hub and bearing assem-
bly and support the drive shaft.
CAUTION:
Do not apply an excessive angle to drive shaft joint when
removing from the wheel hub and bearing assembly,
Do not excessively extend slide joint.
Do not allow drive shaft to hang down. Support the entire drive shaft.
11. Remove wheel hub and bearing assembly bolts, and then remove splash guard and wheel hub and bear-
ing assembly from steering knuckle.

PERIODIC MAINTENANCE
Revision: June 20062007 Versa
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. [ ]: At the mileage intervals only
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.
