Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000CK
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 and SB section 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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake SystemBFS000CL
Recommended fluid is brake fluid “DOT 3” or “DOT 4”. Refer to MA-14, "RECOMMENDED FLUIDS AND
LUBRICANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas.
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 system.
Using a flare nut wrench when removing flare nuts, and use a
flare nut torque wrench when tighten brake tube flare nuts.
When installing brake tubes, be sure to check torque.
Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
battery negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlBFS000CM
During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal condition 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 cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
If there is a radio, antenna, or antenna lead-in wire (including 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, and improper wiring.

CAN CommunicationBFS000G4
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped on a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. Refer to LAN-49, "
CAN Sys-
tem Specification Chart" .

TROUBLE DIAGNOSIS
TROUBLE DIAGNOSISPFP:00004
How to Perform Trouble Diagnosis For Quick and Accurate RepairBFS000CU
INTRODUCTION
Most important point to perform diagnosis is to understand systems (control and mechanism) in vehicle
thoroughly.
It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check symptoms by driving vehicle
with the customer.
NOTE:
Customers are not professionals. Do not assume “maybe the
customer means...” or “maybe the customer mentioned this
symptoms”.
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptoms based on an interview with customers and past
examples. Do not perform inspection on ad hoc basis. Most
intermittent malfunctions are caused by poor contacts. In this
case, it will be effective to shake suspected harness or connec-
tors by hand. When repairs are performed without any symptom
check, no one can judge if malfunction has actually been elimi-
nated.
After diagnosis, make sure to perform “erase memory”. Refer to
BRC-17, "
ERASE MEMORY" .
For an intermittent malfunction, move harness or harness connectors by hand to check poor contacts or
false open circuit.
Always read “GI section” to confirm general precautions. Refer to GI-4, "General Precautions" .

CONSULT-II MAIN FUNCTION
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II SETTING PROCEDURE
Refer to GI-34, "CONSULT-II Start Procedure" .
Self-Diagnosis BFS000D0
DESCRIPTION
If an error is detected in the system, ABS warning lamp on combination meter turn on. In this case, perform
self- diagnosis as follows.
OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Perform “CONSULT-II Starting Procedure”. Refer to GI-34, "
CONSULT-II Start Procedure" .
3. Turn ignition switch ON.
4. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping vehicle, with the engine running, touch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-II screen.
CAUTION:
If “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on the
ignition switch, “ABS” might not be displayed in the System Selection screen. In this case, repeat
the operation from step 1. If it cannot be shown after several attempts, ABS actuator and electric
unit (control unit) may have malfunctioned.
6. The self-diagnostic results are displayed. (Touch “PRINT” to print out self-diagnostic results, if necessary.)
Check ABS warning lamp if “NO FAILURE” is displayed.
7. Perform the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:
When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning
lamp will not turn off even when the system is normal unless the vehicle is driving at approxi-
mately 30 km/h (19 MPH) or more for approximately 1 minute.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE MEMORY” in order on the CONSULT-II
screen to erase the error memory.
CAUTION:
If the error memory is not erased, re-perform the operation from step 4.
3. Perform self-diagnosis again, and make sure that diagnostic memory is erased.
4. Drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make
sure that the ABS warning lamp is off.
