Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS004H7
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 SystemEFS0019O
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; it may cause paint damage. If brake fluid is splashed
on painted areas, wash it away with water immediately.
Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of hydraulic system.
Using a flare nut torque wrench, securely tighten brake tube
flare nuts.
When installing brake piping, be sure to check torque.
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,
gravel, or snowy (fresh deep snow) road.
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,
and improper wiring.

ESP FunctionEFS0019W
1. The Electronic Stability Program is called the ESP for short. ESP is indicated as ESP on CONSULT-II
screen.
2. In addition to the ABS/TCS function, ESP detects a driver's steering operation amount and brake opera-
tion amount from steering angle sensor and pressure sensor. Using the information from yaw rate/side G
sensor and wheel sensors, ESP judges the driving condition (conditions of understeer and oversteer) to
improve the stability by controlling brake on 4 wheels and engine output.
3. During ESP operation, SLIP indicator lamp flashes to inform the driver of the operation.
CAUTION:
During ESP operation, body and the brake pedal lightly vibrate and their mechanical noise may be
heard. This is a normal condition.
If vehicle is rotated on a turn table, or rolled and rocked on a ship, the ABS warning lamp,
ESP OFF indicator lamp, and SLIP indicator lamp may turn on. In this case, start engine on a nor-
mal road again. If the ABS warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp turn
off after the restart, it is normal.
When driving in a steep slope such as a bank, ABS warning lamp, ESP OFF indicator lamp, and
SLIP indicator lamp may turn on. In this case, start the engine on a normal road again. If ABS
warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp turn off after the restart, it is nor-
mal.
TCS FunctionEFS0019V
1. With the wheel sensor signals from 4 wheels, the ESP/TCS/ABS control unit detects a wheel spin. If a
wheel spins, the control unit controls brake fluid pressure to the spinning wheel, and cuts the fuel to the
engine. It also closes the throttle valve to reduce the engine torque. Furthermore, throttle position is con-
trolled to the appropriate engine torque.
2. If a wheel spins, the TCS system works and function by applying brake fluid pressure to the spinning
wheel.

Basic InspectionEFS005W5
BASIC INSPECTION 1 BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake piping and around ESP actuator for leaks. If there is leaking or oozing fluid, check the follow-
ing items.
If ESP actuator connection is loose, tighten piping to the specified torque and re-perform the leak
inspection to make sure there are no leaks.
If there is damage to the connection flare nut or ESP actuator screw, replace the damaged part and re-
perform the leak inspection to make sure there are no leaks.
When there is fluid leaking or oozing from a part other than ESP actuator connection, if fluid is just ooz-
ing out, use a clean cloth to wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out,
replace the damaged part.
CAUTION:
ESP actuator body cannot be disassembled.
3. Check brake pad degree of wear. Refer to BR-27, "
PAD THICKNESS" in “Front Disc Brake” and BR-32,
"PAD WEAR INSPECTION" in “Rear Disc Brake”
BASIC INSPECTION 2 POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the cables. In addition, check the battery voltage to make sure it has not dropped and alter-
nator is normal.

REMOVAL
Pay attention to the following when removing sensor.
CAUTION:
As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.
Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts to specified torques.
When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.
When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in the figure (2 at strut and 1 at body panel). When installed, harness must not be twisted.

INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Always replace exhaust gaskets and seal bearings with new ones when reassembling.
If insulator is badly deformed, repair or replace it. If deposits such as mud pile up on insulator,
remove them.
When installing insulator avoid large gaps or interference between insulator and each exhaust
pipe.
Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.
