NORMAL OPERATING CONDITION

Description

INFOID:0000000006941647

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.)

REMOVAL

Be careful with the following when removing sensor.

CAUTION:

• Never twist sensor harness as much as possible, when removing it. Pull sensors out without pulling

sensor harness.

• Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before remov-

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

• When you see the harness of the wheel sensor from the front side of the vehicle ensure that the

white lines (B) are not twisted.

INSTALLATION

Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
• When installing, make sure there is no foreign material such as iron chips on and in the mounting hole of the

wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.

PRECAUTIONS

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

INFOID:0000000007258389

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• 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.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution for Battery Service

INFOID:0000000007258390

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Service Procedure Precautions for Models with a Pop-up Roll Bar

INFOID:0000000007258391

WARNING:

Always observe the following items for preventing accidental activation.
• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll

over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.

• Before removing and installing the pop-up roll bar component parts and harness, always turn the

ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)

• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS

AIR BAG CONTROL warnings in the Service Manual.

Precaution for Power Generation Voltage Variable Control System

INFOID:0000000007258392

CAUTION:

Revision: 2012 March

2011 Murano CrossCabriolet

CHG-4

< PRECAUTION >

PRECAUTIONS

For this model, the battery current sensor that is installed to the battery cable at the negative terminal
measures the charging/discharging current of the battery, and performs various controls. If the electri-
cal component or the ground wire is connected directly to the battery terminal, the current other than
that being measured with the battery current sensor is charging to or discharging from the battery.
This condition causes the malfunction of the control, and then the battery discharge may occur. Do
not connect the electrical component or the ground wire directly to the battery terminal.
