TROUBLE DIAGNOSIS FOR SYMPTOMS
Excessive ABS Function Operation FrequencyINFOID:0000000001327692
1.CHECK FRONT AND REAR AXLE
Make sure there is no excessive looseness in the front and rear axles.
OK or NG
OK >> GO TO 2.
NG >> Check front or rear axle system.
2.CHECK WHEEL SENSOR
Perform following inspection for wheel sensor:
 Sensor mount and damage inspection
 Sensor rotor mount and damage inspection
 Sensor connector connection inspection
 Sensor harness inspection
OK or NG
OK >> GO TO 3.
NG >> Replace sensor or sensor rotor.
3.CHECK ABS WARNING LAMP DISPLAY
Make sure warning lamp turns off approximately 2 seconds after the ignition switch is turned ON or when driv-
ing.
OK or NG
OK >> Normal
NG >> Perform self-diagnosis. Refer to BRC-26, "
Self-Diagnosis".
Unexpected Pedal ReactionINFOID:0000000001327693
1.CHECK BRAKE PEDAL STROKE
Check brake pedal stroke.
Is the stroke too long?
YES >>  Bleed air from brake piping.  Check brake pedal, brake booster, and master cylinder mount for play, looseness, and brakesystem for fluid leaks, etc. If any malfunctions are found, make repair.
NO >> GO TO 2.
2.CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) c onnector E56 and make sure that braking force is suf-
ficient when ABS in not operating. After the inspection, reconnect connector.
OK or NG
OK >> CHECK WHEEL SENSOR. Refer to BRC-49, "Excessive ABS Function Operation Frequency".
NG >> Check brake system.
The Braking Distance Is LongINFOID:0000000001327694
CAUTION:
On slippery road surfaces, the st opping distance might be longer wi th the ABS operating than when
the ABS is not operating.
1.CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector E56 to deactivate ABS. In this condition,
check stopping distance. After inspection, connect connector.
OK or NG
OK >>  Bleed air from brake piping.  Check brake system.
NG >> CHECK WHEEL SENSOR. Refer to BRC-49, "
Excessive ABS Function Operation Frequency".

Removal and InstallationINFOID:0000000001327698
REMOVAL
1. Disconnect wheel sensor connector.
2. Remove wheel sensor mounting bolts, grommets (front sensor) and clip.
3. Remove wheel sensor.
CAUTION:
Be careful of the followin
g when installing sensor.
 As much as possible, avoid rotati ng sensor when removing it. Pull sensors out without pulling on
sensor harness.
 Take care to avoid damaging sensor edges or roto r teeth. Remove wheel sensor first before remov-
ing front wheel hub and bearing assembly and rear fina l drive. This is to avoid damage to sensor wir-
ing and loss of sensor function.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the follow ing when installing sensor. Tighten in stallation bolts to specified torques.
 When installing, make sure there is no foreign material such as iron chips on pick-up and mounting
hole of sensor. Make sure no foreign material h as been caught in the sensor rotor. Remove any for-
eign material and clean the mount.
 When installing front sensor, be sure to press rubber grommets in until they lock at the three loca-
tions shown in the figure (2 at shock absorbers and 1 at body pa nel). When installed, harness must
not be twisted. White line on ha rness must be visible from front.
 When installing rear sensor, attach harness at rear suspension member securely. Besides, harness
must not be twisted when installed.

Removal and InstallationINFOID:0000000001327700
REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes
from ABS actuator and electric unit (control unit).
3. Remove LH side fender protector. Refer to EI-24
.
4. Remove ABS actuator and electric unit (control unit) mounting nuts.
5. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following wh en removing ABS actuator and electric unit (control unit).
 If the part number on the part number label (p asted on actuator upper surface) is the same, ABS
actuator and electric unit (c ontrol unit) can not be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator lamp
may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator an d electric unit (control unit), must use new service parts.
 Before servicing, disconnect battery cables.
 To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from being
damaged. To install, use a flare nut torque wren ch (commercial service tool) and tighten to the spec-
ified torque.
 Do not apply excessive impact to actuator, such as dropping it.
 Do not remove and install ABS actuator and el ectric unit (control unit) by holding harness.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the following wh en installing ABS actuator and electric unit (control unit).
 Tighten the mounting bolts and nuts to the specified torque.
 After the work, bleed air from brake piping. Refer to BR-8, "
Bleeding Brake System".
 After installing vehicle harness connector in th e actuator, make sure connector is securely locked.
 When replacing ABS actuator and el ectric unit (control unit), calibrate steering angle sensor neutral
position and decel G sensor. Refer to BRC-8
.

SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612910
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Liquid GasketINFOID:0000000001325839
REMOVAL OF LIQUID GASKET SEALING
 After removing mounting nuts and bolts, separate the mating sur- face using the seal cutter (SST) and remove old liquid gasket seal-
ing.
CAUTION:
Be careful not to damage the mating surfaces.
 Tap the seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.
 In areas where seal cutter is difficult to use, use a plastic hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
 Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur- face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

PRECAUTIONS
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
4. Apply liquid gasket without breaks to the specified location with the specified dimensions.
 If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.
 As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
 Within five minutes of liquid gasket application, install the mat-
ing component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten after mounting bolts and nuts the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.
