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).

blown, ignition switch mal-
function, “BLK/WHT” circuit
between “IG” fuse and com-
bination meter or poor cou-

2 1) Turn ignition switch OFF and disconnect
connectors from ECM.
2) Check for proper connection to ECM at ter-
minal G02-12.
3) If OK, then using service wire, ground termi-
nal G02-12 in connector disconnected.
Does immobilizer indicator lamp turn on at igni-
tion switch ON?Substitute a known-
good ECM and
recheck.Bulb burned out or “PNK”

NOTE:
After replacing with a known-good Immobilizer Control Module, register ECM/Immobilizer Control
Module code in ECM and Transponder code and ECM/Immobilizer Control Module code in Immobilizer
Control Module by performing procedure described in “PROCEDURE AFTER IMMOBILIZER CON-
TROL MODULE REPLACEMENT” in this section.

Service on or around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in this section before performing service on or around the air bag system compo-
nents or wiring. Failure to follow WARNINGS could result in unintended activation of the system or
could render the system inoperative. Either of these two conditions may result in severe injury.
The procedures in this section must be followed in the order listed to disable the air bag system
temporarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures
could result in possible activation of the air bag system, personal injury or otherwise unneeded air
bag system repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
If the correct part number fastener is not available, a fastener of equal size and strength (or stronger)
may be used. Fasteners that are not reused, and those requiring thread-locking compound, will be
called out. The correct torque value must be used when installing fasteners that require it. If the above
conditions are not followed, parts or system damage could result.
