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).
NOTE:
All brake fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and / or could result in major repair expense. They must be replaced with one of same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention of all parts. There is to be no welding as it may result in extensive damage and weakening
of the metal.

checking.
NOTE:
When removing and reinstalling switch, use care not to let
dust enter transfer box inside.
Make sure to reset clamp for wiring which is located
where invisible directly.
It is recommended to work on transfer shift control lever
boot No. 1 from underside of vehicle on lift.
Identify this switch by its leg part which is different for that
of back up light switch.

WARNING:
Refrain from work while exhaust center pipe is hot.

INSPECTION OF 4WD SWITCH AND BACK UP LIGHT
SWITCH
1) Undo clamp and disconnect coupler of back up light switch
and / or 4WD switch.
2) Function of back up light switch can be checked as shown in fig-
ure.
There should be conduction at these terminals only when shift
lever is shifted to reverse position.
3) Function of transfer 4WD switch can be checked in the same
manner as back up light switch.
There should be conduction at these terminals when shift lever
is shifted to 4H, and 4L positions.
Upon completion of check, connect coupler and clamp wiring har-
ness as they were.
NOTE:
When replacing switch(es), use care not to let dust enter trans-
mission through switch hole(s).

DTC CONFIRMATION PROCEDURE
WARNING:
When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.
Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC.
3) Start engine and turn O / D cut switch ON.
4) Shift select lever to D range and start vehicle.
5) Keep vehicle speed at higher than 10 km / h (7 mph) with 1st gear in D range for 2 sec. or more.
6) Increase vehicle speed and keep it at higher than 20 km / h (13 mph) with 2nd gear in D range for 2 sec. or more.
7) Increase vehicle speed and keep it at higher than 30 km / h (20 mph) with 3rd gear in D range for 2 sec. or more.
8) Stop vehicle.
9) Check DTC and / or pending DTC.
