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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in FOREWORD of this manual.

•As shown in the figure, use a 12 V battery to connect its (+)
terminal to terminal “A”, and its (–) terminal to “Black” lead
wire (2).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm,
it is proper. For high speed check, connect battery (+) termi-
nal to terminal “B”, and its (–) terminal to “Black” lead wire
(2). If motor rotates at a high revolution speed of 67 to 83
rpm, it is proper.
•Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal “A” of wiper
motor and (–) terminal to Black lead wire (2) and let the
motor turn.
b) Disconnect terminal “A” from battery, and let the motor
stop.
c) Connect terminal “A” and “D” with a jumper wire (3), and
connect terminal “C” to battery (+) terminal. Observe the
motor turns once again then stops at a given position.
d) Repeat a) through c) several times and inspect if the motor
stops at the given position every time.
