RUNNING AN AUTOTEST
Press REPORTS-AUTOTEST, SELECT
Run AutoTest , press NEXT, and follow the on-screen
instructions.
The AutoTest is one of the best and fastest ways to collect comprehensive engine performance
data. The Diagnostic Center will customize the AutoTest based on the ignition type selected
during Engine Setup, the signals received from the test leads, and on the choices you make
during the test. A printed report, complete with graphs, brings all of the saved data together in
a condensed form that is easy to review for signal trends and for comparing cylinder
performance tests. Diagnostic messages, generated during tests, also appear in the printout.
The AutoTest sequence steps through the Starting/Charging History, Ignition Primary ,
Secondary , Timing, and Power Balance tests, and finishes with the Electronic Compression
test. Each of the tests is described in detail in the Engine Testing section of this manual, and
can be run individually at any time. The AutoTest is not available when
Engine Setup "Ignition"
is set to Diesel .
Make sure the engine is warmed up and running, and that all necessary test leads are
connected. Enter the
AutoTest , as described above, and follow the instructions. You will be
prompted to perform a variety of actions during the test sequence, like cranking the engine
during the Starting/Charging History or pressing the NEXT key to continue a test after an action
is performed. The Diagnostic Center will do the rest, and will print a detailed report at the end
of the test.
If your Diagnostic Center is equipped for Emissions testing, you will be prompted to SELECT
whether or not you want to run an
Emissions test as part of the AutoTest .
