Ford Historic Self-Test Routines
If no DTC is present, continue with the
paragraph following the note below. If
any DTC(s) are present, the Cyl
Balance Test stops and the tool displays
the screen to the right.
Select YES to review the DTC(s), then turn engine off. Record them and make
repairs before repeating the Cyl Balance Test.
In the next step, Do Not touch any
vehicle or tool keys while the test is
running. Allow engine to idle. Engine
speed may drop or become uneven —
this is normal.
With no DTCs present, the tool prompts
the user to Depress and release the
Throttle Halfway within the next 1.5
minutes. Press ENTER to continue. Do
not move the throttle.
If throttle is moved, after depressing and releasing the throttle the tool will
display an error message indicating that the test failed due to throttle
movement. It prompts the user to retest the vehicle or return to the Ford
Function List.

screen to the right displays. Press
ENTER to continue.
If a problem exists with one or more
cylinders, the tool displays a list of failed
cylinder(s). Press ENTER to continue.
Refer to the applicable vehicle service
manual for cylinder numbering
sequence. Cylinder failure may be caused by faulty injectors, sparks plugs, or
wiring.
Turn the ignition key Off and press ENTER to continue — the tool prompts the
user to retest (up to three times). If required, rerun the test to double check the
results, or to check for weaker or dead cylinders.
When done, press FUNC to return to the Ford Function List.
