PRECAUTIONS
[ABS]
PRECAUTIONS
[ABS] PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EFS004LN
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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. C
WARNING:
q 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. D
q 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. E
q 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 harness connec-
tors. BRC
Precautions for Brake System EFS004LO
q Recommended fluid is brake fluid "DOT 3" or "DOT 4". G
q Do not reuse the drained brake fluid.
q 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. H
q Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.
q Using a flare nut torque wrench, securely tighten brake tube I
flare nuts.
q Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble malfunctioning parts. If any mal- J
functioning part is found, replace the part with a new one.
q Before working, turn ignition switch OFF and disconnect con-
nectors for ABS actuator and electric unit or battery terminals.
K
q When installing brake piping, be sure to check tightening torque.
SBR820BA L
Precautions for Brake Control EFS004LP
q During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal. M
q When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.
q Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
q When an error is indicated by ABS or another warning lamp, collect all necessary information from the
customer (what symptoms are present under what conditions) and check for simple causes before start-
ing diagnostic servicing. Besides the electrical system inspection, check booster operation, brake fluid
level, and oil leaks.
q 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.
q If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, ABS system
may malfunction or return an error.
q If aftermarket parts (e.g. car stereo equipment, CD player) have been installed, check electrical harnesses
for pinches, open, and improper wiring.

PRECAUTIONS
[ABS]
Precaution for Harness Repair EFS005VW
CAN SYSTEM
q Area to be repaired shall be soldered, and wrapped with a tape
(be sure that fraying of twisted wire shall be within 110 mm 4.33
in)).
PKIA0306E
q Do not make a bypass connection to repaired area. (If it is done,
branch part will be removed and characteristics of twisted wire
will be lost.)

SYSTEM DESCRIPTION
[ABS]
ABS Function EFS004LT
A
q Anti-lock Brake System monitors wheel rotation in braking and electronically controls braking force (brake
fluid pressure) to prevent wheel locking. Thus, it improves vehicle stability in abrupt braking and allows
driver to clear obstacles more easily.
q In the event of an electric system malfunction, the fail-safe function will operate, the vehicle will enter the B
ABS non-operation state, and ABS warning lamp will come on.
q CONSULT-II can be used to diagnose the electrical system.
C
EBD Function EFS004LU
q The electronically controlled braking force distribution unit detects the minute slips that occur in front and
rear wheels during braking and uses electronic control to control rear wheel braking force (brake hydraulic D
pressure) to suppress rear wheel slipping as much as possible to improve stability during braking.
q In the event an electrical system malfunction occurs, the fail-safe function will operate and EBD and ABS
will enter non-operational states, and ABS warning lamp and brake warning lamp will come on. E
q CONSULT-II can be used to diagnose the electrical system.
Fail-Safe Function EFS004LV
BRC
q If a malfunction occurs in ABS system, "ABS warning lamp" turns ON.
q If a malfunction occurs in EBD, brake warning lamp and ABS warning lamp turn ON.

TROUBLE DIAGNOSIS
[ABS]
TROUBLE DIAGNOSIS PFP:00004
Diagnosis Procedure EFS004LX
BASIC CONCEPT
q The most important point in performing trouble diagnosis is to thoroughly understand the vehicle systems
(both control and mechanical).
q It is also important to clarify customer concerns before starting
the inspection.
First of all, reproduce the symptom, and understand it fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check the symptoms by driving the
vehicle with the customer.
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like "maybe the customer means that...," or
"maybe the customer mentions this symptom".
EFJ0028D
q It is essential to check symptoms right from the beginning in
order to repair a error completely.
For an intermittent error, it is important to reproduce the symp-
tom based on an interview with the customer and past exam-
ples. Do not perform an inspection on an ad hoc basis. Most
intermittent errors are caused by poor contacts. In this case, it
will be effective to shake the suspected harness or connector by
hand. When repairs are performed without any symptom diag-
nosis, no one can judge if the error has actually been eliminated.
q After completing trouble diagnosis, be sure to perform "erase
memory". Refer to BRC-22, "SELF-DIAGNOSIS" . SEF233G
q For an intermittent error, move the harness or harness connec-
tor by hand to check for poor contact or false open circuit.
q Always read the GI section to be aware of the general precautions. Refer to GI-4, "General Precautions" .

QUESTIONNAIRE
q Complaints against a malfunction vary depending on each per-
son. It is important to clarify the customer complaints.
q Ask the customer about what symptoms are present and under
what conditions. Use the information to reproduce the symptom
while driving.
q It is also important to use the diagnosis sheet so as not to miss
the information.
