TROUBLE DIAGNOSIS FOR SYSTEM

4. CHECK DATA MONITOR
1. Connect ABS actuator and electric unit (control unit) connector and steering angle sensor.
2. Perform “ST ANGLE SIG” at “DATA MONITOR” to check if the status is normal.
OK or NG
OK >> Perform self-diagnosis again.
NG >> Replace steering angle sensor, and then adjust neutral position of steering angle sensor. Refer to
BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .
Yaw Rate/Side/Decel G Sensor SystemBFS000EC
CAUTION:
When the vehicle turns sharply, such as a spin turn, accel turn, or drift driving, while the VDC function
is OFF (VDC OFF indicator lamp turns on), a malfunction may occur in the yaw rate/side/decel G sen-
sor system, so in this case, restart the engine, and if it recovers normally, there is no malfunction.
Always erase memory after that. Refer to BRC-58, "
ERASE MEMORY" .
INSPECTION PROCEDURE

Removal and InstallationBFS000EQ
COMPONENTS
REMOVAL
Be careful of the following.
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.

Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.

Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.

When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.

PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BCS001NA
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 Necessary for Steering Wheel Rotation After Battery DisconnectBCS001NB
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

SHIFT CONTROL SYSTEM

8. Remove control device assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.

The knurled surface of rib should be upward when installing the
control cable to the control device assembly. And insert the con-
trol cable securely.

After installation is completed, adjust and check CVT position.
Refer to CVT-178, "
Adjustment of CVT Position" and CVT-179,
"Checking of CVT Position" .
Adjustment of CVT PositionBCS001MN
1. Place selector lever in “P” position.
2. Loosen control cable nut and place manual lever in “P” position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park
lock.
3. Hold the control cable at the end. Push and pull it twice or three
times, and then push it with a load of 9.8N (approximately 1 kg,
2.2 lb). Temporarily tighten the lock nut with the control cable
loose.
4. Connect control cable on manual lever.
CAUTION:
No application of a force to the manual lever.
5. Tighten control cable nut.
CAUTION:
Fix the manual lever when tightening.
