TRANSFER ASSEMBLY
Dismounting and remounting of transfer and transmission together
as a unit is described in Section 7A for Manual Transmission or 7B1
for Automatic Transmission, but it is also possible to dismount and
remount transfer assembly by itself as described below.
DISMOUNTING
IN ENGINE ROOM
1) Disconnect negative (±) cable from battery.
2) Remove distributor assembly (if equipped).
3) Place wood block between engine and dash panel so that it
serves as stopper when engine, transmission and transfer unit
hangs down as rear mounting member is removed.
CAUTION:
Make sure to use wood block to prevent contact which
may occur between dash panel and CMP sensor case
(G16), CMP sensor (J20) or intake manifold (H25), and fan
and shroud.
IN CABIN
1) Remove console box.
2) Remove shift lever of transmission and transfer.
ON LIFT
1) Drain transfer oil.
2) Remove rear propeller shaft.
3) Remove front propeller shaft.
4) Disconnect exhaust center pipe.
5) Disconnect speed sensor coupler.
6) Place transmission jack and remove mounting member.
7) Lower transmission jack gradually and check to ensure that
wood block serves as stopper between engine and dash panel.
8) Remove bolts for gear shift lever case.

7E-2 DIFFERENTIAL (FRONT)
4WD CONTROL SYSTEM
When the 4WD switch is turned ON by shifting the transfer shift lever, ECM (PCM) (G16 and J20 engine models)
or 4WD controller (H25 engine model) actuates (energizes) the air pump assembly. Then positive pressure is sent
from the air pump assembly to the actuator installed to the differential case and causes the axle lock clutch and
the free axle hub in the differential case to be engaged, resulting in the 4WD mode. Only when running in the 4WD
mode, front axles are joined to differential case, and they become free when 2WD mode is used (or when transfer
shift lever is shifted to N position), thereby reducing the power loss.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

The wire color is abbreviated to the first (or first two) alphabet(s) of
each color.
There are two kinds of colored wire used in this vehicle. One is
single-colored wire and the other is dual-colored (striped) wire.
The single-colored wire uses only one color symbol (i.e. ªGº).
The dual-colored wire uses two color symbols (i.e. ªG / Yº). The first
symbol represents the base color of the wire (ªGº in the figure) and
the second symbol represents the color of the stripe (ªYº in the fig-
ure).
JOINT CONNECTOR (J / C)

Wiring of this vehicle employs joint connector (J / C) which divide
one wire into several different wires or combine several different
wires into one wire.

The joint connector is as shown in the figure.
