PRECAUTIONS
[TCS/ABS]
PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EFS0034L

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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. C
WARNING:
q 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. D
q 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. E
q 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. BRC
Precautions for Brake System EFS0034M

CAUTION: G
q Refer to MA-10, "RECOMMENDED FLUIDS AND LUBRICANTS" for recommended brake fluid.
q Never reuse drained brake fluid.
q Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is H
splashed on painted areas, wash it away with water immediately.
q To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
q Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic I
system.
q Use flare nut wrench when removing and installing brake
tube. J
q 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.
K
q Turn the ignition switch OFF and remove the connector of
the ABS actuator control unit or the battery terminal before
performing the work.
L
q Always tighten brake lines to specified torque when install-
ing.
SBR686C
q Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage. M
Refer to BR-31, "Brake Burnishing" (front disc brakes) or BR-37, "Brake Burnishing" (rear disc
brakes).
WARNING:
q Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions When Using CONSULT-II EFS0034N

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 carries out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
q If YES, GO TO 2.

q If NO, GO TO 5.

Revision: September 2004 BRC-3 2005 Quest
PRECAUTIONS
[TCS/ABS]
2. Is there any indication other than indications relating to CAN communication system in the self-diagnosis
results?
q If YES, GO TO 3.

q If NO, GO TO 4.

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.
5. Diagnose CAN communication system. Refer to LAN-5, "CAN COMMUNICATION" .
Precautions for Brake Control EFS0034O

q During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
q Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from
engine compartment. This is a normal status of operation check.
q Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
q 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 booster operation, brake fluid level, and fluid leaks.
q 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.
q If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or
error.
q If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits or improper wiring.
Precautions for CAN System EFS0034P

q Do not apply voltage of 7.0V or higher to terminal to be measured.
q Maximum open terminal voltage of tester in use must be less than 7.0V.
q Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.
q 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).

PKIA0306E

q Do not make a bypass connection to repaired area. (If the circuit
is bypassed, characteristics of twisted wire will be lost.)

ABS Function EFS0034U

q The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during H
sudden braking by electrically preventing wheel lockup. Maneuverability is also improved for avoiding
obstacles.
q If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and I
the ABS warning lamp turns on.
q The electrical system can be diagnosed using CONSULT-II.
q During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is J
normal.
q Just after starting the vehicle, the brake pedal may vibrate or a motor operating noise may be heard from
engine compartment. This is a normal status of operation check. K
q Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
L
EBD Function EFS0034V

q Electronic Brake Distribution is a function that detects subtle slippages between the front and rear wheels
during braking, and it improves handling stability by electronically controlling the brake fluid pressure
M
which results in reduced rear wheel slippage.
q If the electrical system malfunctions, the Fail-Safe function is activated, the EBD and ABS become inoper-
ative, and the ABS warning lamp and BRAKE warning lamp are turned on.
q The electrical system can be diagnosed using CONSULT-II.
q During EBD operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
q Just after starting the vehicle, the brake pedal may vibrate or a motor operating noise may be heard from
engine compartment. This is a normal status of operation check.
TCS Function EFS0034W

q Spinning of the drive wheels is detected by the ABS/TCS control unit using inputs from the wheel speed
sensors. If wheel spin occurs, engine fuel cut is conducted while the throttle value is restricted to reduce
the engine torque and decrease the amount of wheel spin. In addition, the throttle opening is controlled to
achieve the optimum engine torque.
q Depending on road condition, the vehicle may have a sluggish feel. This is normal, because optimum trac-
tion has the highest priority during TCS operation.

Revision: September 2004 BRC-7 2005 Quest
SYSTEM DESCRIPTION
[TCS/ABS]
q TCS may be activated during sudden vehicle acceleration, wide open throttle acceleration, sudden trans-
mission shifts or when the vehicle is driven on a road with a varying surface friction coefficient.
q The SLIP indicator lamp flashes to inform the driver of TCS operation.
Wheel Sensors EFS0034X

Each wheel sensor unit consists of a wheel hub with a series of inter-
nal magnets and a sensor element. The wheel sensors are installed
on the inner side of the wheel knuckles. As the wheel rotates, the
sensor generates a square-wave signal. The frequency increases as
the wheel speed increases.

WFIA0033E

Fail-Safe Function EFS0034Y

CAUTION:
If the Fail-Safe function is activated, perform the Self Diagnosis for ABS/TCS system.
ABS/EBD SYSTEM
In case of an electrical malfunction with the ABS, the ABS warning lamp and SLIP indicator lamp will turn on.
In case of an electrical malfunction with the EBD system, the BRAKE warning lamp, ABS warning lamp and
SLIP indicator lamp will turn on.
The system will revert to one of the following conditions of the Fail-Safe function.
1. For ABS malfunction, only the EBD is operative and the condition of the vehicle is the same condition of
vehicles without ABS/TCS system.
2. For EBD malfunction, the EBD and ABS become inoperative, and the condition of the vehicle is the same
as the condition of vehicles without ABS/TCS and EBD system.
TCS SYSTEM
In case of TCS system malfunction, the SLIP indicator lamp is turned on and the condition of the vehicle is the
same as the condition of vehicles without TCS system. In case of an electrical malfunction with the TCS sys-
tem, the ABS control continues to operate normally without TCS control.

How to Perform Trouble Diagnoses for Quick and Accurate Repair EFS00351

INTRODUCTION
The ABS/TCS system has an electronic control unit to control major B
functions. The control unit accepts input signals from sensors and
controls actuator operation. It is also important to check for conven-
tional problems such as air leaks in the booster or lines, lack of
brake fluid, or other problems with the brake system. C
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electrical connections or faulty wiring. In this case, D
careful checking of suspicious circuits may help prevent the replace-
ment of good parts.
A visual check only may not find the cause of the problem, so a road
test should be performed.
SEF233G
E
Before undertaking actual checks, take just a few minutes to talk with
a customer who approaches with an ABS/TCS complaint. The cus-
tomer is a very good source of information on such problems, espe- BRC
cially intermittent ones. Through the talks with the customer, find out
what symptoms are present and under what conditions they occur.
Start your diagnosis by looking for "conventional" problems first. This
is one of the best ways to troubleshoot brake problems on an ABS/ G
TCS equipped vehicle. Also check related Service Bulletins for infor-
mation.

Basic Inspection EFS00355

BRAKE FLUID LEVEL, FLUID LEAK, AND BRAKE PAD INSPECTION
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.
q If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and recheck for leaks.
q If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) threads,
replace the damaged part and recheck for leaks.
q 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
actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assem-
bly.
CAUTION:
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.
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.
ABS WARNING LAMP, SLIP INDICATOR LAMP AND TCS OFF INDICATOR LAMP INSPECTION
1. Make sure ABS warning lamp, SLIP indicator lamp and TCS OFF indicator lamp (when TCS OFF switch
is off), turn on for approximately 1 second when the ignition switch is turned ON. If they do not, check the
TCS OFF indicator lamp and the TCS OFF switch. Refer to BRC-35, "TCS OFF SWITCH" . Check CAN
communications. If there are no errors with the TCS OFF switch or the CAN communication system,
check combination meter. Refer to DI-5, "COMBINATION METERS" .
2. Make sure the lamps turn off approximately 1 second after the ignition switch is turned ON. If the lamp
does not turn off, conduct self-diagnosis.
3. With the engine running, make sure the TCS OFF indicator lamp turns on and off when the TCS OFF
switch is turned on and off. If the indicator lamp status does not correspond to switch operation, check the
TCS OFF switch. Refer to BRC-35, "TCS OFF SWITCH" .
4. Make sure ABS warning lamp, SLIP indicator lamp and TCS OFF indicator lamp turn off approximately 2
seconds after the engine is started. If ABS warning lamp, SLIP indicator lamp or TCS OFF indicator lamp
have not turned off 10 seconds after the engine has been started, conduct self-diagnosis of the ABS actu-
ator and electric unit (control unit).
5. After conducting the self-diagnosis, be sure to erase the error memory. Refer to BRC-23, "CONSULT-II
