PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EFS0068W

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
G 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.
G 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.
G 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 System EFS004P9

CAUTION:
G Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" for recommended brake fluid.
G Never reuse drained brake fluid.
G Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
G To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
G Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.
G Use flare nut wrench when removing and installing brake
tube.
G If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
G Turn the ignition switch OFF and remove the connector of
the ABS actuator and electric unit (control unit) or the bat-
tery terminal before performing the work.
G Always torque brake lines when installing.
G Burnish the brake contact surfaces after refinishing or SBR686C
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to BR-28, "BRAKE BURNISHING PROCEDURE" (front disc brake) or BR-34, "BRAKE BUR-
NISHING PROCEDURE" (rear disc brake).
WARNING:
G Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions When Using CONSULT-II EFS004PA

When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
G If YES, GO TO 2.

Revision: August 2006 BRC-4 2007 Titan
PRECAUTIONS
[ABS]
G If NO, GO TO 5.
2. Is there any indication other than indications relating to CAN communication system in the self-diagnosis A
results?
G If YES, GO TO 3.

G If NO, GO TO 4. B
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefor, erase the self-diagnosis results. C
5. Diagnose CAN communication system. Refer to LAN-5, "TROUBLE DIAGNOSIS" .
Precautions for Brake Control EFS004PB D
G During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
G Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from E
engine compartment. This is a normal status of operation check.
G Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads. BRC
G 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
diagnosis. Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid G
leaks.
G If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate. H
G If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or
error.
G If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness I
pinches, open circuits or improper wiring.
Precautions for CAN System EFS004PC

G Do not apply voltage of 7.0V or higher to terminal to be measured. J
G Maximum open terminal voltage of tester in use must be less than 7.0V.
G Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.
K
G Area to be repaired must be soldered and wrapped with tape.
Make sure that fraying of twisted wire is within 110 mm (4.33 in).

How to Perform Trouble Diagnoses for Quick and Accurate Repair EFS004PM

INTRODUCTION
The ABS system has an electronic control unit to control major func-
tions. The control unit accepts input signals from sensors and con-
trols actuator operation. It is also important to check for conventional
malfunctions such as air leaks in the booster or lines, lack of brake
fluid, or other malfunctions with the brake system.
It is much more difficult to diagnose a malfunction that occurs inter-
mittently rather than continuously. Most intermittent malfunctions are
caused by poor electrical connections or wiring. In this case, careful
checking of suspicious circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the malfunction, so a
SEF233G
road test should be performed.
Before undertaking actual checks, take just a few minutes to talk with
a customer who approaches with an ABS complaint. The customer
is a very good source of information, especially for intermittent mal-
functions. Through the talks with the customer, find out what symp-
toms are present and under what conditions they occur.
Start your diagnosis by looking for "conventional" malfunctions first.
This is one of the best ways to troubleshoot brake malfunctions on
an ABS equipped vehicle. Also check related Service Bulletins for
information.

Basic Inspection EFS004PQ

BRAKE FLUID LEVEL, FLUID LEAK, AND BRAKE PAD INSPECTION A
1. Check fluid level in the brake fluid reservoir. If fluid level is low, add fluid.
2. Check the brake piping and around the ABS actuator and electric unit (control unit) for leaks. If there is
leaking or seeping fluid, check the following items. B
G If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and recheck for leaks.
G If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) threads, C
replace the damaged part and recheck for leaks.
G When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and
recheck for leaks. If fluid is still seeping out, replace the damaged part. If the fluid is leaking at the ABS D
actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assem-
bly.
CAUTION: E
The ABS actuator and electric unit (control unit) cannot be disassembled and must be replaced
as an assembly.
3. Check the brake pads for excessive wear. BRC
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, make
sure the battery is sufficiently charged. G
ABS WARNING LAMP INSPECTION
1. Make sure ABS warning lamp turns on for approximately 2 seconds when the ignition switch is turned ON.
If it does not, check CAN communications. If there are no errors with the CAN communication system, H
replace the combination meter. Refer to DI-5, "COMBINATION METERS" .
2. Make sure the lamp turns off approximately 2 seconds after the ignition switch is turned ON. If the lamp
does not turn off, conduct self-diagnosis of ABS actuator and electric unit (control unit). If no malfunctions I
are detected in self-diagnosis, replace combination meter. Refer to DI-5, "COMBINATION METERS" .
3. After conducting the self-diagnosis, be sure to erase the error memory. Refer to BRC-22, "CONSULT-II
