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.

Adjustment of Steering Angle Sensor Neutral PositionEFS0019R
In case of doing work that applies to the list below, make sure to adjust neutral position of steering angle sen-
sor before running vehicle.
×: Required
–: Not required
CAUTION:
To adjust neutral position of steering angle sensor, make sure to use CONSULT-II.
(Adjustment cannot be done without CONSULT-II.)
1. Stop vehicle with front wheels in straight-ahead position.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition
switch ON (do not start engine).
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
3. Touch “ABS”, “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-II screen in
this order. Refer to BRC-79, "
CONSULT-II BASIC OPERATION PROCEDURE" .
4. Touch “START”.
CAUTION:
Do not touch steering wheel while adjusting steering angle
sensor.
5. After approximately 10 seconds, touch “END”. (After approxi-
mately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to carry out above operation.
7. Run vehicle with front wheels in straight-ahead position, then
stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-II screen.
Then make sure “STR ANGLE SIG” is within 0 ±3.5 deg. If value is more than specification, repeat steps 1
to 7.
9. Erase memory of ESP/TCS/ABS control unit and ECM.
10. Turn ignition switch OFF.

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.
