PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012430820
The Supplemental Restraint System such as “A IR 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 SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 three minutes before performing any service.
Precaution for Brake SystemINFOID:0000000012430821
WARNING:
Clean any dust from the front brake and rear brake using a vacuum dust collector. Do not blow by
compressed air.
• Brake fluid use refer to MA-11, "
Fluids and Lubricants".
• Do not reuse drained brake fluid.
• Do not 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.
• Always confirm the specified tightening torque when installing the brake pipes.
• After pressing the brake pedal more deeply or harder t han normal driving, such as air bleeding, check each
item of brake pedal. Adjust brake pedal if it is outside the standard value.
• Do not use mineral oils such as gasoline or light oil to clean. 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 connect the battery terminal when moving the vehicle.
• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) harness connector or the battery negative
terminal before performing the work.
• Check that no brake fluid leakage is present after replacing the parts.

Precaution for Brake Control SystemINFOID:0000000012430822
• Just after starting vehicle after ignition switch is ON, brake pedal may vibrate or motor operating noise may be heard from engine compartment. This is a 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 simple causes before starting diagnostic
servicing. Besides electrical system inspection, c heck brake booster operation, brake fluid level and oil
leaks.
• If tire size and type are used in an improper combinati on or brake pads are not Genuine NISSAN parts, stop-
ping 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 indi cator 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.), tire s, 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.
Precaution for Harness RepairINFOID:0000000012430823
• Solder the repair part, and wrap it with tape. [Twisted wire fray
must be 110 mm (4.33 in) or less.]
• Do not bypass the repair point with wire. (If it is bypassed, the turn- out point cannot be separated and the twisted wire characteristics
are lost.)

Switches the fluid pressure line to increase or hold according to signals from control unit.
ABS OUT Valve
Switches the fluid pressure line to increase, hold or decrease according to signals from control unit.
Cut Valve 1, Cut Valve 2
Shuts off the ordinary brake line from master cylinder, when VDC function and TCS function are activated.
Suction Valve 1, Suction Valve 2
Supplies the brake fluid from master cylinder to the pump, when VDC function and TCS function are activated.
Return Check Valve
Returns the brake fluid from brake caliper and wheel cyli nder to master cylinder by bypassing orifice of each
valve when brake is released.
Reservoir
Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreases when
decreasing pressure of brake caliper and wheel cylinder.
Yaw rate/side/decel G sensor
Calculates the following information that affects the v ehicle, and transmits a signal to ABS actuator and elec-
tric unit (control unit) via communication lines:
• Vehicle rotation angular velocity (yaw rate signal)
• Vehicle lateral acceleration (side G signal) and longitudinal acceleration (decel G signal)
Pressure Sensor
Detects the brake fluid pressure and transmits signal to ABS actuator and electric unit (control unit).
Wheel Sensor and Sensor RotorINFOID:0000000012430829
NOTE:
• Wheel sensor of front wheel is installed on steering knuckle.
• Sensor rotor of front wheel is integrated in wheel hub assembly.
• Wheel sensor of rear wheel is installed on back plate of rear brake.
• Sensor rotor of rear wheel is installed on rear brake drum.
• Never measure resistance and voltage value using a tester because sensor is active sensor.
• Downsize and weight reduction is aimed. IC for detection portion
and magnet for sensor rotor are adopted.
• Power supply is supplied to detection portion so that magnetic field
line is read. Magnetic field that is detected is converted to current
signal.
• When sensor rotor rotates, magnetic field changes. Magnetic field
change is converted to current signals (rectangular wave) and is
transmitted to ABS actuator and electric unit (control unit). Change
of magnetic field is pr oportional to wheel speed.
Stop Lamp SwitchINFOID:0000000012430830
Detects the operation status of brake pedal and transmits converted electric signal to ABS actuator and elec-
tric unit (control unit).
Steering Angle SensorINFOID:0000000012430831
Detects the following information and transmits steering angle signal to ABS actuator and electric unit (control
unit) via CAN communication:
• Steering wheel rotation amount
• Steering wheel rotation angular velocity
• Steering wheel rotation direction

Front RH brake caliper
• Brake fluid is conveyed to the pump from the master cylinder through suction valve 1 and is pressurized by
the pump operation. The pressurized brake fluid is supplied to the front RH brake caliper through the ABS IN
valve. For the left caliper, brake fluid pressure is maintained because the pressurization is unnecessary. The
pressurization for the left caliper is cont rolled separately from the right caliper.
Front LH brake caliper• Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by
the pump operation. The pressurized brake fluid is suppl ied to the front LH brake caliper through the ABS IN
valve. For the right caliper, brake fluid pressure is maintained because the pressurization is unnecessary.
The pressurization for the right caliper is controlled separately from the left caliper.
Rear RH wheel cylinder
• Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by
the pump operation. The pressurized brake fluid is supplied to the rear RH wheel cylinder through the ABS
