FUNCTION INSPECTION
With engine stopped, discharge stored vacuum by depressing brake
pedal several times at 5 second intervals. With brake pedal fully
depressed, start the engine. Confirm that clearance between brake
pedal and floor panel decreases when engine vacuum stabilizes.
AIRTIGHTNESS INSPECTION

Run engine at idle for approximately 1 minute. Stop it after
applying vacuum to the booster. Depress brake pedal several
times with normal force to discharge the stored vacuum. Con-
firm that clearance between brake pedal and floor panel gradu-
ally increases as the brake pedal is depressed.

Run engine. Depress and hold brake pedal then stop engine.
Keep brake pedal depressed for 30 seconds or more and make
sure the pedal stroke does not change.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS005X6
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 SystemEFS004GX

Recommended fluid is brake fluid “DOT 3” or “DOT 4”.

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut torque wrench, securely tighten brake tube
flare nuts.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.

Before working, turn ignition switch OFF and disconnect har-
ness connectors of ABS actuator and electric unit (control unit)
or battery cable from negative terminal.

When installing brake piping, be sure to check torque.
Precautions for Brake ControlEFS004FV

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 compartment. 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 malfunction is indicated by ABS or another warning lamp, collect all necessary information from
customer (what symptoms are present under what conditions) and check for simple causes before start-
ing diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level,
and oil leaks.

If tyre 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.

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

DIAGNOSIS PRECAUTIONS

Before performing the trouble diagnosis, always read the general information (GI) to confirm the general
precautions. Refer to GI-4, "
General Precautions" .

After completing service, always erase the self-diagnosis results. Refer to BRC-28, "Operation Proce-
dure" .

When inspection of the continuity or voltage between units is performed, check connector terminals for
disconnection, looseness, bend, or collapse. If any non-standard condition is detected, repair or replace
applicable part.

Intermittent malfunctions may be caused by a poor connection in the harness, connector, or terminal.
Move harnesses, harness connectors, or terminals by hand to make sure all connections are solid and
undamaged.

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

While a phenomena like those shown in the following table may occur, this is not malfunction because the
system is working normally.

Before working, turn the ignition switch OFF and disconnect the
connectors for the ESP/TCS/ABS control unit and control unit or
the battery negative terminal.

Burnish the brake pad contact surfaces after refinishing or
replacing drums or rotors, after replacing pads or linings, or if a
soft pedal occurs at very low mileage. Refer to BR-31, "
BRAKE
BURNISHING PROCEDURE" .
WARNING:
Clean brakes with a vacuum dust collector to minimize risk of health hazard from powder caused
by friction.
Precautions for Brake ControlEFS0019P

During the ESP/TCS/ABS operation, the brake pedal vibrates lightly and its mechanical noise may be
heard. This is a normal condition.

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

The stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough,

If a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary infor-
mation from the customer (what symptoms are present under what conditions) and find out the possible
causes before starting the service. Besides the electrical system inspection, check the booster operation,
brake fluid level, and oil leaks.

If the tyre size and type are used in a improper combination, or the brake pads are not NISSAN genuine
parts, the stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, the ESP/TCS/
ABS function may have a malfunction.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check harnesses for pinches, open,

SYSTEM DESCRIPTION

3. During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.
CAUTION:

During TCS operation, body and brake pedal lightly vibrate and the mechanical noise may be
heard. This is a normal condition.

Depending on road circumstances, a driver may have a sluggish feel. This is not malfunction,
because the optimum traction has the highest priority by TCS operation.

When the vehicle is passing through a road where the surface friction coefficient varies, down-
shifting or depressing the accelerator pedal fully may activate TCS temporarily.
ABS FunctionEFS0019U
1. In cases of braking suddenly or braking on slippery road (ice road), ABS functions prevent wheels from
lock, improve the stability in sudden braking, and make efficient avoidance of obstacles with steering
manipulation by detecting wheel speed and controlling brake fluid pressure.
2. EBD is integrated in ESP/TCS/ABS system.
CAUTION:

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

When starting engine, or just after starting vehicle, brake pedal may vibrate or the motor operating
noise may be heard from engine compartment. This is a normal status of the operation check.

The stopping distance may be longer than that of vehicles without ABS when vehicle drives on
rough, gravel, or snowy (fresh deep snow) road.
EBD FunctionEFS004HO

Electronic Brake Distributor is a function that detects subtle slippages between front and rear wheels dur-
ing braking, and it improves handling stability by electronically controlling the brake fluid pressure which
results in reduced rear wheel slippage.

In case of electrical system break down, the fail-safe function is activated, EBD and ABS becomes inoper-
ative, and ABS warning lamp and brake warning lamp are turned on.

Electrical System Diagnosis by CONSULT-II is available.
Fail-Safe FunctionEFS004HP
ESP/ TCS SYSTEM
In case of throttle control system trouble, ESP OFF indicator lamp and SLIP indicator lamp are turned on, and
the condition of vehicle is the same as the condition of vehicles without ESP/TCS equipment. In case of trou-
ble to the throttle control system, the ABS control continues to operate normally without ESP/TCS control.
CAUTION:
If the fail-safe function is activated, then perform the self- diagnosis for ESP/TCS/ABS control system.
ABS, EBD SYSTEM
In case of electrical malfunctions with the ABS, ABS warning lamp, ESP OFF indicator lamp and SLIP indica-
tor lamp will turn on. In case of electrical malfunctions with the EBD, brake warning lamp, ABS warning lamp,
ESP OFF indicator lamp and SLIP indicator lamp will turn on. Simultaneously, the ESP/ TCS/ABS become one
of the following conditions of the fail-safe function.
1. For ABS trouble, only the EBD is activated and the condition of vehicle is the same condition of vehicles
without ESP/TCS/ABS equipment.
2. For EBD trouble, the EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without ESP/TCS/ABS, EBD equipment.
NOTE:
In condition 1 described above, an 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.
