DescriptionECS004SM
The vehicle speed sensor·MTR is built into the speedometer assem-
bly. The sensor functions as an auxiliary device to the revolution sen-
sor when it is malfunctioning. The TCM will then use a signal sent
from the vehicle speed sensor·MTR.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EDS001W1
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.
PrecautionsEDS001V6

Before connecting or disconnecting the 4WD control unit
harness connector, turn ignition switch “OFF” and discon-
nect battery ground cable. Because battery voltage is
applied to 4WD control unit even if ignition switch is turned
“OFF”.

When connecting or disconnecting pin connectors into or
from 4WD control unit, take care not to damage pin termi-
nals (bend or break).
When connecting pin connectors, make sure that there are
no bends or breaks on 4WD control unit pin terminal.

Before replacing 4WD control unit, perform 4WD control
unit input/output signal inspection and make sure whether
4WD control unit functions properly or not. Refer to TF-30,
"4WD Control Unit Input/Output Signal Reference Values" .

System DescriptionEDS001VB
ELECTRIC CONTROLLED COUPLING
Operation Principle
1. The 4WD control unit supplies command current to electric con-
trolled coupling (4WD solenoid).
2. The control clutch is engaged by electromagnet and torque is
detected in control clutch.
3. The cam operates in response to control clutch torque and
applies pressure to main clutch.
4. The main clutch transmits torque to front wheels according to
pressing power.

Transmission torque to the rear wheels is determined accord-
ing to command current.
4WD CONTROL UNIT

4WD controls distribution of drive power between front-wheel
drive (100:0) and 4WD (50:50) conditions according to signals
from sensors.

Self-diagnosis can be done with CONSULT-II.

ALL MODE 4X4 SYSTEM

4WD MODE SWITCH
AUTO Mode

Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.

4WD mode makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.

On roads which do not require 4WD, AUTO mode contributes to improved fuel economy by driving in con-
ditions close to front-wheel drive.

Sensor inputs determine the vehicle's turning condition, and tight cornering/braking are controlled by dis-
tributing optimum torque to rear wheels.
LOCK Mode

Front/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.

Vehicle will switch automatically to AUTO mode if vehicle speed increases. If vehicle speed then
decreases, the vehicle automatically returns to direct 4-wheel driving conditions.

LOCK mode will change to AUTO mode automatically, when the vehicle speed exceeds approx. 30 km/h
(19 MPH). The LOCK indicator light keeps illuminating.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
LOCK mode may be prohibited, or speeds at which LOCK mode is enabled may be restricted detecting tire
conditions.
2WD Mode
Vehicle is in front-wheel drive.
NOTE:

If front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for
the system.

Even if the 4WD mode switch is in 2WD mode, the 4WD control unit occasionally automatically change to
AUTO mode depending on the driving condition (For example; Depressing the acceleration firmly). This is
not malfunction. However, 4WD indicator lamp dose not illuminate.
4WD INDICATOR LAMP AND LOCK INDICATOR LAMP
The following is the indications of indicator lamp.
4WD WARNING LAMP
Turns ON when there is a malfunction in 4WD system. It indicates that the vehicle is in fail-safe mode and
change to front-wheel drive or shifting driving force-4WD (Rear-wheels still have some driving torque).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1
seconds after the engine starts if system is normal.
