Precaution for Brake Control

INFOID:0000000009482877

• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is

normal.

• Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from engine

compartment. This is a normal status of operation check.

• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or

snow-covered (fresh, deep snow) roads.

• 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 simple causes before starting diagnosis.

Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid leaks.

• If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts, stop-

ping distance or steering stability may deteriorate.

• If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or

error.

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

pinches, open circuits or improper wiring.

• If the following components are replaced with non-genuine components or modified, the VDC OFF indicator

lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components

related to suspension (shock absorbers, struts, springs, bushings, etc.), tires, wheels (exclude specified

size), components related to brake system (pads, rotors, calipers, etc.), components related to engine (muf-

fler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).

• Driving with broken or excessively worn suspension components, tires or brake system components may

cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC system may not

operate properly.

• When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The

noise is a result of the normal operation of the TCS and VDC.

• When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as

sharp curves on a freeway), the VDC may not operate normally, or the VDC warning lamp and the SLIP indi-

cator lamp may turn on. This is not a problem if normal operation can be resumed after restarting the engine.

• Sudden turns (such as spin turns, acceleration turns), drifting, etc. with VDC turned off may cause the yaw

rate/side/decel G sensor to indicate a problem. This is not a problem if normal operation can be resumed

after restarting the engine.

• If battery is removed or steering angle sensor is disconnected, power to steering angle sensor is lost and the

screen goes into steering angle sensor safe mode.

• When screen goes into steering angle sensor safe mode, perform "Adjustment of Steering Angle Sensor

Neutral Position" with CONSULT and check that VDC OFF indicator turns off. Additionally, perform self-diag-

nosis, check that only "Steering Angle Sensor Safe Mode" is shown for self-diagnostic result, and then

delete the memory. (If the self-diagnostic result shows an indication other than "Steering Angle Sensor Safe

Mode", repair the relevant part and restart self-diagnosis.) The steering angle sensor is released and returns

to normal condition by performing the above operation.

• When checking, if only "Steering Angle Sensor Safe Mode" is shown in the self-diagnostic result and VDC

OFF indicator is off, delete history of malfunction. This happens when battery power supply is lost and the

screen goes into Steering Angle Sensor Safe Mode, and then screen returns to normal mode automatically

by driving the vehicle in a straight forward direction [for approximately 30 seconds at 20 km/h (12 MPH) or

more] after power is supplied again.

NOTE:

VDC OFF indicator lamp is on when VDC OFF switch is on.

Precaution for CAN System

INFOID:0000000009482878

• Do not apply voltage of 7.0V or higher to terminal to be measured.

• Maximum open terminal voltage of tester in use must be less than 7.0V.

• Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.

PRECAUTIONS

• Area to be repaired must be soldered and wrapped with tape.

Make sure that fraying of twisted wire is within 110 mm (4.33 in).

• Do not make a bypass connection to repaired area. (If the circuit is

bypassed, characteristics of twisted wire will be lost.)

REMOVAL

1. Remove the front disc rotor, if removing the front wheel sensor. Refer to 

BR-34, "Removal and Installation

of Brake Caliper and Disc Rotor"

.

2. Remove the wheel sensor bolt(s).
3. Pull the wheel sensor straight out, being careful to turn it as little as possible.

CAUTION:

• Be careful not to damage the wheel sensor edge and sensor rotor teeth.

• Do not pull on the wheel sensor harness.

4. Disconnect the wheel sensor harness connector, then remove the wheel sensor harness from the mounts

to remove the wheel sensor.

INSTALLATION

Installation is in the reverse order of removal.

• Before installing the wheel sensors do the following:

- Inspect and replace the wheel sensor if damaged.

- Clean the wheel sensor hole and mating surface with brake cleaner and a lint-free cloth. Be careful that dirt

and debris do not enter the hub and bearing assembly or the rear axle.
