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).

Intermittent Wiper Relay Circuit
1) Disconnect negative cable at battery.
2) Disconnect combination switch lead wire coupler.
3) Turn the front wiper switch to INT position.
4) Turn the intermittent time control switch to FAST position.
5) Connect battery positive terminal to terminal ªB3º and battery
negative terminal to terminal ªEº.
6) Connect voltmeter positive lead to terminal ª+1º and negative
lead to terminal ªEº.
Check that the voltmeter indicates the battery voltage (10 ±
14 V).
7) Connect terminal ªAsº and terminal ªB3º by a jumper wire. Then
move jumper wire end connected to terminal ªB3º to terminal ªEº.
Observe the voltmeter voltage drops to 0 V right after connecting
the jumper wire from terminal ªB3º to ªEº. Then the voltage rises
to battery voltage (10 ± 14 V) within the time shown in the table
below.

2) TESTING AUTOMATIC STOP ACTION
a) First, connect battery (+) terminal to terminal ªDº and battery
(±) terminal to black lead wire (2) and let the motor (1) turn.
b) Then disconnect terminal ªDº from battery and let the motor
stop.
c) Next connect terminal ªDº and terminal ªAº with a jumper wire
(3) and connect terminal ªBº to battery (+) terminal. Observe the
wiper motor turns once again, then stops at a given position.
d) Repeat these steps several times, and inspect if the motor
stops at the given position every time.
Rear Wiper Intermittent Relay
[ON circuit]
1) Connect positive terminal of battery to terminals ª1º and ª4º of
relay, negative terminal to terminal ª5º of relay and check voltage
between terminals ª6º and ª5º of relay.
If measured voltage is battery voltage, relay is in good condition.
If not, replace relay.
2) Connect positive terminal of battery to terminal ª2º of relay, then
disconnect positive terminal from terminal ª4º of relay and check
voltage between terminals ª6º and ª5º of relay.
If measured voltage is battery voltage, relay is in good condition.
If not, replace relay.
3) Disconnect positive terminal from terminal ª2º of relay and check
voltage between terminals ª6º and ª5º of relay.
If measured voltage is about 0 V, relay is in good condition.
If not, replace relay.
[WASH circuit]
1) Connect positive terminal of battery to terminal ª1º of relay and
negative terminal to terminal ª5º of relay. Then connect positive
terminal to terminal ª7º checking voltage between terminals ª6º
and ª5º of relay.
If measured voltage changes from about 0 V to battery voltage
0.6 to 1.5 seconds after connecting positive terminal to terminal
ª7º, relay is in good condition. If not, replace relay.

2) Disconnect positive terminal from terminal ª7º checking voltage
between terminal ª6º and ª5º of relay.
If measured voltage changes from battery voltage to about 0 V
2.7 to 4.6 seconds after disconnecting positive terminal from ter-
minal ª7º, relay is in good condition.
If not, replace relay.
[INT circuit]
1) Connect positive terminal of battery to terminals ª1º of relay and
negative terminal to terminal ª5º of relay. Then positive terminal
to terminal ª3º of relay checking voltage between terminals ª6º
and ª5º of relay.
If measured voltage changes from about 0 V to battery voltage
when connecting positive terminal to terminal ª3º, relay is in
good condition.
If not, replace relay.
2) Connect positive terminal of battery to terminal ª2º of relay, then
disconnect positive terminal from terminal ª2º of relay checking
voltage between terminals ª6º and ª5º of relay.
If measured voltage changes from battery voltage to about 0 V
when disconnecting positive terminal from terminal ª2º and
about 0 V to battery voltage 8
2 seconds after disconnecting
positive terminal from terminal ª2º, relay is in good condition.
If not, replace relay.

1) Disconnect power door lock controller coupler.
2) Connect (+) wire and (±) wire of 12 V battery to terminal ªAº, ªEº
and ªFº as shown in figure.
3) Disconnect cord from terminal ªEº and connect it to terminal ªGº.
4) Repeat Steps 2) and 3) several times and if relay operation is
heard every time, it means that controller is operating.
POWER DOOR LOCK CONTROLLER (HARD TOP MODEL)
1) With the driver side door key turned LOCK, check all power
doors are locked.
2) With the driver side door key turned UNLOCK, check only the
driver side power door is unlocked.
Turn the driver side door key to UNLOCK again within 5 se-
conds, check all power doors are unlocked.
If check result of Step 1) and Step 2) is satisfactory, power door lock
controller is OK. If check result is not satisfactory, go to next Step 3).
3) Disconnect negative cable at battery.
4) Disconnect coupler of power door lock controller.
5) Use a 12 V battery to connect its (+) terminal to terminal E02-1,
and its (±) terminal to terminal E02-2 and E02-3. Check all power
doors are locked.
If check result is not satisfactory, repair circuit and recheck.
If check result is satisfactory, go to next Step 6).
