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.

UNEXPECTED PEDAL REACTION
UNEXPECTED PEDAL REACTION
Diagnosis ProcedureINFOID:0000000012430919
1.CHECK BRAKE PEDAL STROKE
Check brake pedal stroke. Refer to BR-9, "
Inspection and Adjustment".
Is the stroke too big?
YES >> • Bleed air from brake line and hose. Refer to BR-13, "Bleeding Brake System".
• Check brake pedal, brake booster, and master cylinder for mount play, looseness, brake system fluid leakage, etc. Refer to brake pedal: BR-9, "
Inspection and Adjustment" or brake booster
assembly BR-15, "
Inspection".
NO >> GO TO 2.
2.CHECK ABS FUNCTION
1. Disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS.
2. Check if braking force is normal in this condition.
3. Reconnect connector after inspection.
Is the inspection result normal?
YES >> Inspection End.
NO >> Check brake system.

Exploded View".
CAUTION:
Cap or wrap the joint of the A/C piping and expan sion valve with suitable material such as vinyl
tape to avoid the entry of air.
5. Remove low-pressure flexible hose. Refer to HA-28, "
LOW-PRESSURE FLEXIBLE HOSE : Removal and
Installation".
6. Loosen flare nut from brake tubes using a flare nut wrench, then remove brake tubes from ABS actuator
and electric unit (control unit). Refer to BR-22, "
FRONT : Exploded View".
7. Disconnect the harness connector from the ABS actuator and electric unit (control unit).
8. Remove ABS actuator and electric unit (control unit) bracket bolts.
9. Remove the ABS actuator and electric uni t (control unit) and bracket as an assembly.
10. Remove bracket and bushing from ABS ac tuator and electric unit (if necessary).
INSTALLATION
Installation is in the reverse order of removal.
• Bleed the brake system. Refer to BR-13, "
Bleeding Brake System".
• Adjust the neutral position of steering angle sensor. Refer to BRC-55, "
ADJUSTMENT OF STEERING
ANGLE SENSOR NEUTRAL POSITION : Special Repair Requirement".
CAUTION:
• Replace the ABS actuator electric unit (control unit) if it has been dropped or sustained an impact.
• Do not install actuator by holding harness.
• After installing harness connector in the ABS acu tator and electric until (control unit), make sure
