NORMAL OPERATING CONDITION

NORMAL OPERATING CONDITION

Description

INFOID:0000000003766858

Symptom

Result

Slight vibrations are felt on the brake pedal and the operation noises occur, when ABS is activated. 

This is a normal condi-
tion due to the ABS acti-
vation.

Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or 
snow-covered (fresh, deep snow) roads.

The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and 
just after the vehicle starts.

This is a normal, and it is 
caused by the ABS op-
eration check.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000003893848

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 AIRBAG” and
“SEAT BELT” 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 performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000003928740

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

Precaution for Brake System

INFOID:0000000003766860

WARNING:

Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
• Only use “DOT 3” or “DOT 4” brake fluid. Refer to 

MA-11, "Fluids and Lubricants"

.

• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off

immediately and wash with water if it gets on a painted surface.

• Never use mineral oils such as gasoline or light oil. They may damage rubber parts and cause improper

operation.

• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with a flare

nut torque wrench (A).

• Always conform the specified tightening torque when installing the

brake pipes.

• 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.

• Turn the ignition switch OFF and disconnect the ABS actuator and

electric unit (control unit) connector or the battery negative terminal
before performing the work.

PRECAUTIONS

Precaution for Brake Control

INFOID:0000000003766861

• When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor

operating noise may be heard from engine compartment. This is normal condition.

• When an error is indicated by ABS or another warning lamp, collect all necessary information from customer

(what symptoms are present under what conditions) and check for estimate causes before starting diagnos-
tic servicing. Besides electrical system inspection, check brake booster operation, brake fluid level, and oil
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.

• ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in wire

near the control unit.

• If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness

pinches, open circuits, and improper wiring.

Precautions for Harness Repair

INFOID:0000000003859437

COMMUNICATION LINE

• Solder the repaired area and wrap tape around the soldered area.

NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).

• Bypass connection is never allowed at the repaired area.

NOTE:
Bypass connection may cause communication error as spliced
wires that are separate from the main line or twisted lines lose
noise immunity. 

• Replace the applicable harness as an assembly if error is detected

on the shield lines of communication line.

ing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.

INSTALLATION

Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
Refer to 

BRC-57, "FRONT WHEEL SENSOR : Exploded View"

.

CAUTION:

• When installing, make sure there is no foreign material such as iron chips on and in the mounting
