BRC-106

< PRECAUTION >

[TYPE 1]

PRECAUTIONS

5. When the repair work is completed, return the ignition switch to the 

LOCK

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT. 

Precaution for Brake System

INFOID:0000000007356805

CAUTION:

• Refer to 

MA-18, "FOR USA AND CANADA : Fluids and Lubricants"

 (United States and Canada), 

MA-

20, "FOR MEXICO : Fluids and Lubricants"

 (Mexico) for recommended brake fluid.

• Never reuse drained brake fluid.

• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is

splashed on painted areas, wash it away with water immediately. 

• To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.

• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic sys-

tem. 

• Use flare nut wrench when removing and installing brake

tube. 

• If a brake fluid leak is found, the part must be disassembled

without fail. Then it has to be replaced with a new one if a

defect exists. 

• Turn the ignition switch OFF and remove the connector of the

ABS actuator and electric unit (control unit) or the battery ter-

minal before performing the work. 

• Always torque brake lines when installing.

• Burnish the brake contact surfaces after refinishing or replac-

ing rotors, after replacing pads, or if a soft pedal occurs at

very low mileage.

Refer to 

BR-41, "Brake Burnishing"

 (front disc brake) or 

BR-46, "Brake Burnishing"

 (rear disc brake).

WARNING:

• Clean dust on caliper and brake pads with a vacuum dust collector to minimize the hazard of air-

borne particles or other materials.

Precaution for Brake Control

INFOID:0000000007356806

• 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:0000000007356807

• 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.

• 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.)
