Spark Fire Test
is test allows individual spark outputs to be red.
• WARNING: Engine backre and external ame can occur during
this test. As a safety precaution purge fuel vapors from the engine
before proceeding. Do not remove the ame arrestor if the engine is
equipped with one.
• IMPORTANT: Before performing this test disconnect the engine’s
Crank Position Sensor.
• This test must be performed with Key-On and Engine Off.
Upon selecting this test you will be prompted to select the spark output to re.
Spark outputs follow cylinder number order. Use the ▲ and ▼ keys to select the
desired spark output and then press the TEST key to start the test. e test will
run for approximately 10 seconds. Use an inductive pickup KV tester to verify
the spark output’s operation.
• To abort the Spark Fire test at any time, press and hold the scanner’s
NO key.
Injector Fire Test
is test allows individual fuel injectors to be pulsed. e test must be performed
with Key ON/ Engine OFF. is test is intended to be used for injector leak-
down testing and it can assist a technician in identifying clogged injectors. A fuel
pressure gauge is normally used in conjunction with this test. Refer to the engine
manufacturer’s service literature for specic details and procedures on injector
testing.
Upon selecting this test you will rst be prompted to select a fuel injector ON
time. e ON time can be adjusted from 1 to 200 milliseconds. Use the ▲ and
▼ keys to set the injector ON time and then press the YES key to proceed to the
test. Holding either the ▲ or ▼ key continuously for more than two seconds
accelerates the injector ON time adjustment.
Aer setting the time and pressing YES you will be prompted to select the fuel
injector to pulse. Use the ▲ and ▼ keys to select the desired fuel injector and
then press the TEST key to activate the injector.
Aer the injector is pulsed you will be prompted to run the engine for a short
period of time to clear out the unburned fuel from the cylinder. e test cannot
be re-run unless the fuel clear out procedure is performed.
