Injector Solenoid Test
The purpose of the injector solenoid test is to
diagnose injector wiring and injector solenoid
functionality.
This test identifies an open circuit or a short circuit in
the circuit for the injector solenoids. The test
activates the injector solenoids one at a time when
the engine is not running. A good solenoid will create
an audible click when the solenoid is activated. The
electronic service tool indicates the status of the
solenoid as “OK” , “Open” , or “Short” .
The injectors must be powered to enable the
automatic test to be run. To start the test, select the
“Start” button. The automatic test will continually
cycle through the injectors until the “Stop” button is
selected.
There are no test results if the “Change” button is
selected to power or cutout an individual injector.
When selected, the “Power All” and “Cutout All”
buttons do not give test results.
