(d) Error Readout. E0001 is a typical error readout. There are 15 different readouts. All error readouts
start with E. An error readout is a warning that you forgot to connect the transducer, selected a wrong test
number, failed to start the engine, etc. All of the error messages mean you must correct the problem before
continuing testing. Error readouts are listed in table 2-3. If the error message does not go away after
corrective action, refer to TM 9-4910-571-12&P.
(e) Confidence Error Readouts. C004 is a typical error readout resulting from the detection of a
faulty VTM during confidence test. For detailed information concerning confidence error readouts refer to
Table 2-1. Status Readouts.
A readout of .220.127.116.11 appears for 1 to 2 seconds each time the power is applied to the VTM.
It means that there is power to the VTM, and that all elements of the readout display are
A readout of ---- indicates the following
(1) After power turn on it signifes that the VTM is ready for testing.
(2) During a compression unbalance test it signifies testing is in progress.
A readout of ..18.104.22.168 indicates that the VTM is reading a test value beyond the range of
its measurement, capability. Either (1) the wrong test number is selected for the
parameter being measured, or (2) there is a fault in the vehicle.
A PASS or FAIL readout is the result of a test that checks the condition of a component
being measured. A PASS/FAIL readout means just that the component either passes
the test or fails the test.
