NORMAL OPERATING CONDITION

Description

INFOID:0000000003132995

Symptom

Result

Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is acti-
vated. 

This is a normal condi-
tion due to the VDC, 
TCS or ABS activation.

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 moves and generates noises, when TCS or VDC is activated due to rapid acceleration or 
sharp turn.

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.

Depending on the road conditions, the driver may experience a sluggish feel. 

This is normal, because 
TCS places the highest 
priority on the optimum 
traction (stability).

TCS may activate momentarily if wheel speed changes when driving over location where friction coefficient 
varies, when downshifting, or when fully depressing accelerator pedal.

The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn ON when the vehicle is 
subject to strong shaking or large vibration, such as when the vehicle is rotating on a turntable or located on 
a ship while the engine is running. 

In this case, restart the 
engine on a normal 
road. If the normal con-
dition is restored, there 
is no malfunction. At 
that time, erase the self-
diagnosis memory.

VDC may not operate normally or the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp 
may illuminate, when running on a special road that is extremely slanted (e.g. bank in a circuit course). 

A malfunction may occur in the yaw rate/side G sensor system, when the vehicle turns sharply, such as dur-
ing a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illuminated). 

The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the 
speedometer on a 2-wheel chassis dynamometer. 

Normal (Deactivate the 
VDC/TCS function be-
fore performing an in-
spection on a chassis 
dynamometer.)

VDC OFF indicator lamp and SLIP indicator lamp may simultaneously turn on when low tire pressure warn-
ing lamp turns on.

This is not a VDC sys-
tem error but results 
from characteristic 
change of tire.

PRECAUTIONS

PRECAUTION

PRECAUTIONS

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

INFOID:0000000003132996

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
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”.

• 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 har-
ness connectors.

Precaution for Brake System

INFOID:0000000003132997

WARNING:

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

MA-10, "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 crow-

foot (A) and torque wrench (B).

• 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.

Precaution for Brake Control

INFOID:0000000003132998

• 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.

• VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light. 
- When replacing the following parts with parts other than genuine parts or making modifications: Suspension

related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-related
parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-related parts
(roll bar, tower bar, etc.).

- When driving with worn or deteriorated suspension, tires and brake-related parts.

Precautions for Harness Repair

INFOID:0000000003733509

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.
