COMPONENTS
REMOVAL
Be careful of the following:
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.

Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.

Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.

When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.

ACTUATOR AND ELECTRIC UNIT (ASSEMBLY)

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 ABS actuator and electric unit (control unit) mounting bolts.
4. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).

If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) cannot be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, may turn ON or ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.

Before servicing, disconnect both 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 wrench (commercial service tool) and tighten
with the specified torque.

Do not apply excessive impact to actuator, such as dropping it.

Do not remove and install ABS actuator and electric unit (control unit) by holding harness.
INSTALLATION
Install is in the reverse order of the removal.
CAUTION:
Be careful of the following when installing ABS actuator and electric unit (control unit).

Tighten the mounting bolts and nuts with the specified torque.

After the work, bleed air from brake piping. Refer to BR-10, "Bleeding Brake System" .

After installing body harness connector in the actuator, make sure connector is securely locked.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000G3
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:

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 SystemBFS000DL

Recommended fluid is brake fluid “DOT 3” or “DOT 4”. Refer to MA-14, "RECOMMENDED FLUIDS AND
LUBRICANTS" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas.

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.

Using a flare nut wrench when removing flare nuts, and use a
flare nut torque wrench when tighten brake tube flare nuts.

When installing brake tubes, be sure to check torque.

Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
battery negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlBFS000DM

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

If the following components are replaced with non-genuine components or converted, the VDC OFF indi-
cator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Compo-
nents related to suspension (Shock Absorber, Strut, Spring, Bush, etc.), Tires, wheels (exclude specified

size), components related to brake (Pad, Rotor, Caliper, etc.), Components related to engine (Muffler,
ECM, etc.), Components related to body reinforcement (Roll bar, Tower bar, etc.).

Driving in the condition of breakage or excessive wear of the suspension, tires or components related to
the brakes may cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC
system may not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or the VDC OFF indicator lamp and the
SLIP indicator lamp may turn on. However, this is not a incident if normal operation can be resumed after
restarting the engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc; when VDC function is OFF (VDC OFF
switch ON), may cause that the yaw rate/side/decel G sensor system indicate a incident. However this is
not a incident if normal operation can be resumed after restarting the engine.
