Performing the STE Self-test
The STE-M1/FVS has a built-in self-testing capability that is used to
determine that the test set is ready for use.  The self-test is also
used to identify fault symptoms within the test set and to confirm
that maintenance actions have corrected any previous problem in the
test set.  The self-test should always be performed before using the
test set on the vehicle.
The STE self-test consists of making various entries into the VTM or
SETCOM unit and receiving appropriate responses on the displays of
those two units.
If, at any time during the self-test, the proper
response is NOT displayed by the test equipment, then the test set or
a component of the test set is faulty.
a. Powering Up the Test Set.
Once the STE has been properly
hooked up to the vehicle, the power must be turned on.
