c. While pulling outer socket slowly in±11 . 5 m m (±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
d. If rack sliding force is not within specification, overhaul steering
gear assembly.
CHECKING FRONT WHEEL TURNING ANGLE
lCheck front wheel turning angle after toe-in inspection. Place
front wheels on turning radius gauges and rear wheels on
stands. Check the maximum inner and outer wheel turning
angles for LH and RH road wheels.
lWith the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.
lMeasure rack stroke if angles are outside the specified value.
lDisassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.
lSteering angles are not adjustable. Check steering gear assem-
bly, steering column assembly and front suspension compo-
nents for wear or damage if any of the turning angles are
different from the specified value. Replace any of them, if any
non-standard condition exists.Rack sliding force: 210 - 270 N

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EDS003IE
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:
lTo 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.
lImproper 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.
lDo 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 Differential Case Assembly and Differential Lock Control Unit
Replacement
EDS003AG
lWhen replacing differential case assembly or differential lock control unit, check the DIFF LOCK indicator
pattern and adjustment of the position between differential case assembly and differential lock control unit
if necessary.
CHECK DIFF LOCK INDICATOR LAMP
1. Start engine. Run engine for at least 10 seconds.
2. Turn 4WD shift switch to “4LO” and confirm 4LO indicator lamp is turned on. Refer toTF-16, "
4WD SHIFT
SWITCH AND INDICATOR LAMP".
3. Stop vehicle and turn differential lock mode switch to “ON”.
4. Drive vehicle at 7 km/h (4 MPH) or less.
NOTE:
Differential case assembly must be given a rotation from rear left wheel and rear right wheel.
5. Check if DIFF LOCK indicator lamp flashes to turn on.
6. Check if DIFF LOCK indicator lamp and 4LO indicator lamp are changed properly as follows.
lIf each indication and state is OK, rear final drive assembly and differential lock control unit is working cor-
rectly.
lIf each indication and state is NG, rear final drive assembly and differential lock control unit is not working
correctly. Refer toRFD-34, "
METHOD FOR ADJUSTMENT".

COMPONENTS FUNCTION DESCRIPTION
CAN CommunicationEDS003AT
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
For details, refer toDI-65, "
CAN Communication Unit".
