PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003893848
The Supplemental Restraint System such as “AIR 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 “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
WARNING:
 To avoid rendering the SRS inoperative, 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 incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000003928740
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000003766860
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
 Only use “DOT 3” or “DOT 4” brake fluid. Refer to MA-11, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
 Never 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.
 Never use mineral oils such as gasoline or light oil. 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 flare
nut torque wrench (A).
 Always conform the specified tightening torque when installing the
brake pipes.
 Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.
 Turn the ignition switch OFF and disconnect the ABS actuator and
electric unit (control unit) connector or the battery negative terminal
before performing the work.

CAUTION:
Do not touch steering wheel while adjusting steering angle sensor.
3. After approximately 10 seconds, touch “END”.
NOTE:
After approximately 60 seconds, it ends automatically.
4. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to perform above operation.
>> GO TO 3.
3.CHECK DATA MONITOR
1. Run the vehicle with front wheels in straight-ahead position, then stop.
2. Select “STR ANGLE SIG” in “DATA MONITOR” and check steering angle sensor signal.
Is the steering angle within the specified range?
YES >> GO TO 4.
NO >> Perform the neutral position adjustment for the steering angle sensor again, GO TO 1.
4.ERASE THE SELF-DIAGNOSIS MEMORY
Erase the self-diagnosis memories of the ABS actuator and electric unit (control unit) and ECM.
 ABS actuator and electric unit (control unit): Refer to BRC-80, "
CONSULT-III Function".
 ECM: Refer to EC-113, "
CONSULT-III Function".
Are the memories erased?
YES >> INSPECTION END
NO >> Check the items indicated by the self-diagnosis. STR ANGLE SIG : 0±2.5°

NOTE:
1: A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.
ACTIVE TEST
CAUTION:
 Do not perform active test while driving vehicle.
 Make sure to completely bleed air from brake system.
 The active test cannot be started when ABS warning lamp, VDC OFF indicator lamp, SLIP indicator
lamp and brake warning lamp are ON.
 ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are ON
during active test.
NOTE:
 When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor.)
 “TEST IS STOPPED” is displayed 10 seconds after operation start.
 After “TEST IS STOPPED” is displayed, to perform test again.
