5.20 KOEO Injector Buzz
This test is available on some Ford trucks equipped with
a diesel engine. The KOEO Injector Buzz is a functional
test performed on demand with the ignition key on and
engine off. The test determines if the injector circuits
and solenoids are operating correctly and without faults.
All injectors are buzzed initially (audible feedback of
solenoids energizing the valves) for approximately 2
seconds. Then each injector buzzes individually for
approximately 1 second, in numerical order (1 – 8).
From the On Demand Tests Menu:
1. Select KOEO Injector Buzz.
• Use the UP and DOWN keys until KOEO
Injector Buzz is highlighted.
