WARNING:
For vehicles equipped with a Supplemental Inflatable Restraint Air Bag System:

Service on or around Air Bag System Components or Wiring must be performed only by an authorized
Suzuki dealer. Please observe all WARNINGS and SERVICE PRECAUTIONS in Section 9J under “On-
Vehicle Service” and the Air Bag System Component and Wiring Location view in Section 9J before
performing service on or around Air Bag System Components or Wiring. Failure to follow WARNINGS
could result in unintended air bag deployment or could render the air bag inoperative. Either of these
two conditions may result in severe injury.

SDM can maintain sufficient voltage to cause a deployment of air bags for up to 15 seconds after igni-
tion switch is turned to “LOCK” position, battery is disconnected or fuse powering SDM is removed.
Work must be started after 15 seconds from the time.
NOTE:
For the descriptions for vehicle without warm up three way catalytic converter (WU TWC), refer to the same
section of the Service Manual mentioned in the FOREWORD of this manual.

FUEL INJECTOR
ON-VEHICLE INSPECTION
1) With battery negative cable disconnected, disconnect injector
coupler.
2) Connect ohmmeter to each injector terminal and measure resis-
tance.
Resistance of injector: 0.5 – 1.5 Ω at 20C (68F)

3) Connect injector coupler.
4) Remove air cleaner assembly without disconnecting IAT sensor
coupler.
5) Check that fuel is injected out in conical shape from fuel injector
when cranking or running engine.
If no fuel is injected, check wiring harness for continuity and cou-
plers for proper connection referring to “DIAGNOSTIC FLOW
TABLE B-1”.
If fuel is not injected out in conical shape, replace injector.
6) Check injector for fuel leakage after injection is stopped (i.e., af-
ter cranking or engine stop).
Replace if leakage exists.
Fuel leakage: Less than 1 drop/min.
7) Install air cleaner assembly.
