Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951721
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 severi ty 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 NISS AN/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:0000000009463735
WARNING:
Clean any dust from the front brake and rear br ake using a vacuum dust collector. Do not blow by
compressed air.
• Brake fluid use refer to BR-8, "Inspection"
.
• 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 flar e 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.

Work ProcedureINFOID:0000000009463769
CAUTION:
• Use “Manual Configuration” only when “TYPE ID” of ABS actuator an d electric unit (control unit)
cannot be read.
• After configuration, turn the ignition switch from OFF to ON and check that the VDC warning lamp
turns OFF after staying illuminated for approximately two seconds.
• If an error occurs during configurat ion, start over from the beginning.
1.CHECKING TYPE ID (1)
Use FAST (service parts catalogue) to search ABS ac tuator and electric unit (control unit) of the applicable
vehicle and find “Type ID”.
Is
“Type ID” displayed?
YES >> Print out “Type ID” and GO TO 2.
NO >> “Configuration” is not required for ABS actuat or and electric unit (control unit). Replace in the
usual manner. Refer to BRC-128, "Removal and Installation"
.
2.CHECKING TYPE ID (2)
CONSULT Configuration
1. Select “Before Replace ECU” of “Read/Write Configuration”.
2. Check that “Type ID” is displayed on the CONSULT screen.
Is
“Type ID” displayed?
YES >> GO TO 3.
NO >> GO TO 7.
3.VERIFYING TYPE ID (1)
CONSULT Configuration
Compare a “Type ID” displayed on the CONSULT screen with the one searched by using FAST (service parts
catalogue) to check that these “Type ID” agree with each other.
NOTE:
For the “Type ID” searched by using FA ST (service parts catalog), use the last five digits of the “Type ID”.
>> GO TO 4.
4.SAVING TYPE ID
CONSULT Configuration
Save “Type ID” on CONSULT.
>> GO TO 5.
5.REPLACING ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) (1)
Replace ABS actuator and electric unit (control unit). Refer to BRC-128, "Removal and Installation"
.
CAUTION:
Never perform the following work items:
• Air bleeding
>> GO TO 6.
6.WRITING (AUTOMATIC WRITING)
CONSULT Configuration
1. Select “After Replace ECU” of “R e/programming, Configuration” or that of “Read / Write Configuration”.
2. Select the “Type ID” agreeing with the one stored on CONSULT and the one searched by using FAST (service parts catalogue) to write the “Type ID” in to the ABS actuator and electric unit (control unit).
