REAR WIPER MOTOR
INSPECTION
Wiper Motor
Use a 12 V battery to connect its (+) and (-) terminals to terminal
“L” and terminal “E” respectively. Then motor should rotate at 35
to 45 rpm.
Automatic Stop Operation

ative terminal to terminal “E” and let the motor turn.
2) Disconnect terminal “L” from battery positive terminal and let
the motor stop.
3) Connect terminal “B” to battery positive terminal. Observe
the motor turns once again then stops at a specified position.
4) Repeat Step 1) to 3) several times, and check that the motor
stops at the specified position every time.

HOW TO REGISTER IGNITION KEY ........... 8G-23 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).
