BRAKE TUBE AND HOSEPFP:46210
Hydraulic CircuitBFS000FY
CAUTION:

All brake tubes and hoses must be free from excessive bending, twisting and pulling.

Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.

Brake tubes and hoses is an important safety part. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe off them and wash it away with water
immediately.

Do not bend or twist brake hose sharply, or strongly pull it.

When removing components, cover brake line connections so that no dirt, no dust, or other for-
eign matter gets in.

Refill with new brake fluid “DOT 3 or DOT4”.

Do not reuse drained brake fluid.

[ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000CK
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 SystemBFS000CL

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 ControlBFS000CM

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 condition 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.

5. CHECK WHEEL SENSOR HARNESS
1. Turn ignition switch OFF and disconnect malfunctioning wheel
sensor connector E10 (FR-RH), E38 (FR-LH), C2 (RR-RH), C3
(RR-LH) and ABS actuator and electric unit (control unit) con-
nector E240.
2. Check continuity between terminals. (Also check continuity
when the steering wheel is turned right and left and when the
sensor harness inside the wheel house is moved.)
OK or NG
OK >> GO TO 6.
NG >> Repair or replace harness and connector that have malfunction.
6. CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1. Disconnect malfunctioning wheel sensor connector.
2. Turn ignition switch ON and check voltage between wheel sen-
sor harness connector power supply terminal and ground.
OK or NG
OK >> Replace wheel sensor.
NG >> Replace ABS actuator and electric unit (control unit).
