TROUBLE DIAGNOSIS

For Fast and Accurate DiagnosisEFS005W4
PRECAUTIONS FOR DIAGNOSIS

Before performing diagnosis, always read precautions. Refer to BRC-60, "How to Proceed With Diagno-
sis" .

If ESP/TCS/ABS control unit steering angle sensor, steering system parts or suspension system parts
have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of steering angle
sensor before driving. Refer to BRC-52, "
Adjustment of Steering Angle Sensor Neutral Position" .

After diagnosis is finished, be sure to erase memory. Refer to BRC-81, "SELF-DIAGNOSIS" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

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.

To use CONSULT-II to perform self-diagnosis of ESP/TCS/ABS control unit active tests, or work support,
first stop work, then connect CONSULT-II and select “ABS”.

While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system malfunction may be indicated. In this case, start engine to resume the normal screen.

ESP/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:

Brake Warning Lamp
×: ON –: OFF Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ESP/TCS/ABS control unit. Slight noise
may occur during ESP, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and
valves operating noise may be heard. It happens only once after ignition
switch is ON. This is a normal status of the system operation check.
System operation check
noiseWhen engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check.Normal
ESP/TCS operation
(SLIP indicator lamp blink-
ing)TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when downshifting, or
when fully depressing accelerator pedal.Normal
Cancel the ESP/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 coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, 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

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS001FF
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 Steering SystemEGS00049

In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.

Observe the following precautions when disassembling.
–Before disassembly, thoroughly clean the outside of the unit.
–Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
–For easier and proper assembly, place disassembled parts in order on a parts rack.
–Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.

CHECKING CONDITION OF INSTALLATION

Check installation conditions of steering gear assembly, front suspension, axle and steering column.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check steering gear assembly mounting bolts and nut for looseness. Refer to PS-16, "COMPONENT" .
CHECKING STEERING WHEEL PLAY

Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.

When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL

Make sure that steering gear assembly, steering column and steering wheel are installed in the correct
position.

Perform neutral position inspection after wheel alignment. Refer to FSU-6, "Wheel Alignment" .

Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80°C (122 to 176°F).]
4. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position.
NOTE:

Multiply the distance (L) from the hook of spring scale to the
center of steering wheel by the measurement value with a
spring scale.

Perform the following manner when the guideline value is
hard to be measured.
a. Park vehicle on a level and dry surface, set parking brake.
b. Remove driver air bag module. Refer to SRS-30, "
DRIVER AIR BAG MODULE" .
c. Start engine at idle, then check steering wheel turning force with
pre-load gauge [SST].
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-27,
"OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION" .

Removal and InstallationEGS001BZ
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set front wheels in the straight-ahead direction.
2. Remove driver air bag module. Refer to SRS-30, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST].
INSTALLATION
Reverse the removal procedure for installation attentive to the following operation.
NOTE:
About the neutral position, wind spiral cable lightly clockwise until it
is tightened. Turn it counterclockwise (approximately 2.5 turns and a
quarter of a turn) and stop turning it after aligning it with the adjust-
ment mark. (Since service parts are fixed with a stopper with the
neutral position adjusted, installation is possible without any adjust-
ment after removing the stopper.)
CAUTION:
Do not run spiral cable idle needlessly. And do not turn it more
than necessary (or it leads to disconnection of the cable).
