Precautions for Brake ControlNFS000Q1
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is normal condition.
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 oil 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.
ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in
wire near the control unit.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
–When replacing the following parts with parts other than genuine parts or making modifications: Suspen-
sion-related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-
related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-
related parts (roll bar, tower bar, etc.).
–When driving with worn or deteriorated suspension, tires and brake-related parts.

SYSTEM DESCRIPTION
Revision: 2006 January2006 M35/M45
from 4 wheel sensors. When ABS actuator and electric unit (control unit) detects a spin at drive wheels
(rear wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid
pressure are controlled, while fuel being cut to engine and throttle valve being closed to reduce engine
torque by the control unit. Further more, throttle position is continuously controlled to ensure the optimum
engine torque at all times.
During TCS operation, it informs driver of system operation by flashing SLIP indicator lamp.
Electrical system diagnosis by CONSULT-II is available.
VDC
Vehicle Dynamics Control system detects driver's steering operation amount and brake pedal travel from
steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel
sensor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving
stability by controlling brake application to 4 wheels and engine output.
During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
Electrical system diagnosis by CONSULT-II is available.
ECD
Receives deceleration degree commandment value signal from ICC sensor integrated unit, and controls brake
fluid pressure with the motor (built-in ABS actuator and electric unit (control unit)).
Operation That Is Not "System Error" NFS000Q7
ABS
When starting engine or just after starting vehicle, brake pedal may vibrate or the motor operating sound
may be heard from engine room. This is a normal states of the operation check.
During ABS operation, brake pedal lightly vibrates and a mechanical sound may be heard. This is normal.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
TCS
Depending on road circumstances, driver may have a sluggish feel. This is normal, because optimum
traction has highest priority under TCS operation.
When vehicle is passing through a road where surface friction varies, downshifting or depressing acceler-
ator pedal fully may activate TCS temporarily.
VDC
During VDC operation, body and brake pedal lightly vibrate and mechanical sounds may be heard. This is
normal.
If vehicle is rotated on turn table, or rolled and rocked on ship, ABS warning lamp, VDC OFF indicator
lamp, and SLIP indicator lamp may turn on. In this case, start engine on normal road again. If ABS warn-
ing lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off after restart, it is normal.
When starting TCS or VDC under rapid acceleration or hard turn, operating sound by brake pedal is gen-
erated. However, this is not malfunction. This is because TCS and VDC are functioning normally.
VDC may not operate normally or ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp
may turn on when driving special roads with extremely steep slant (banks on circuit road and so on.) How-
ever, it is not malfunction when returning to a normal state after restarting the engine. In that case, be sure
to erase the memory of self-diagnosis. Refer to BRC-23, "
ERASE MEMORY" .
Yaw rate /side G sensor malfunction may occur under hard turn like spin turn, rapid acceleration turn, drift
run, etc., when VDC function is OFF (VDC OFF switch is turned on). It is not malfunction if it is possible to
return to a normal position after restarting engine. Then erase the memory of self-diagnosis. Refer to
BRC-23, "
ERASE MEMORY" .
VDC OFF indicator lamp and SLIP indicator lamp may simultaneously turn on when low tire pressure
warning lamp turns on. This is not a VDC system error but results from characteristic change of tires.
Fail-Safe FunctionNFS000Q8
ABS, EBD SYSTEM
In the event there is a malfunction with the electrical system, the ABS warning lamp, VDC OFF indicator lamp,
and SLIP indicator lamp will turn on when it is the ABS that is malfunctioning, and the brake warning lamp,
ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp will turn on when it is the EBD that is

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
For Fast and Accurate DiagnosisNFS000QJ
PRECAUTIONS FOR DIAGNOSIS
Before performing diagnosis, always read General Information (GI) to confirm general precautions. Refer
to GI-4, "
General Precautions" .
If steering angle sensor, steering system parts, suspension system parts, ABS actuator and electric unit
(control unit) or tires have been replaced, or if wheel alignment has been adjusted, be sure to adjust neu-
tral position of steering angle sensor before driving. Refer to BRC-6, "
Adjustment of Steering Angle Sen-
sor Neutral Position" .
After diagnosis is finished, be sure to erase memory. Refer to BRC-23, "ERASE MEMORY" .
When checking continuity and voltage between unit, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfunction is found, repair or replace connector terminals.
For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.
If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
The following symptoms may be caused by normal operations.
Symptom Symptom description Result
Motor operation soundThis is sound of motor inside VDC actuator. Slight sound may occur
during VDC, TCS, and ABS operation.
Normal
Just after engine starts, the motor operating sound may be heard. This
is a normal condition of the system operation check.
System operation check
soundWhen engine starts, slight “click” sound may be heard from engine
room. This is normal and is part of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp ON)TCS may activate momentarily if wheel speed changes when driving
over location where friction varies, when downshifting, or when fully
depressing accelerator pedal.Normal
Cancel the VDC/TCS
function for the
inspection on a chas-
sis dynamometer. When checking speed meter etc. with a 2-wheel-drive chassis dyna-
mometer, vehicle speed is not increased by pressing down on the accel-
erator.
ABS operation (Longer stop-
ping distance)On roads with low friction, such as snowy roads or gravel roads, vehi-
cles with ABS may require a longer stopping distance. Therefore, when
driving on such roads, avoid overconfidence and keep speed sufficiently
low.Normal
Insufficient feeling of accel-
erationDepending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.Normal

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Revision: 2006 January2006 M35/M45
ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
IntroductionNBS004SL
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
The above information can be checked using procedures listed in the table below.
: Applicable —: Not applicable
*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-108,
"Fail-Safe Chart" .)
Two Trip Detection LogicNBS004SM
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic items will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.
: Applicable —: Not applicable
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is
malfunction on engine control system.
