E033
Error in entry of power test constants.
Status Messages
Status messages keep the operator informed of what is happening.
DISPLAY
MEANING
.8.8.8.8
There is power to the VTM, and the display is working properly. This appears only
for a short period after power is turned on.
.9.9.9.9
VTM is reading a test value beyond its range.
PASS
Unit under test has passed test, or VTM has accepted a control function entry.
FAIL
Unit under test has failed test.
CON
Accepted control function input.
AUE
Numerical display is an average value.
LO
Engine speed below 1600 rpm during SI power test indicates the engine failed the
power test.
–1–1–1–1–1
VTM is busy.
Numerical Readouts
Units of measurement (psi, rpm, Volts, etc.) are not displayed. Numerical readouts indicate the measured value in units of the
measurement being made. For example, if you are measuring 0–45 volts dc, 12.7 is volts dc. If you are measuring 0–25 psig
pressure, 12.7 is psig. The units for each test are listed on the flip cards. Also, the readout will alternate between displaying
values and displaying vehicle identification data (VID).
Prompting Messages
Prompting messages tell the operator to do something. After the operator action is completed, testing will continue. Some of
the prompting messages and their meanings are as follows:
DISPLAY
MEANING
UEH
Tells the operator to enter VID on the TEST SELECT switches.
CYL
Tells the operator to enter the number-of-cylinders into the VTM.
GO
Tells the operator to crank engine.
0066
Tells the operator to set TEST SELECT switches to 99 during confidence test.
CAL
Tells the operator to release the TEST button during an offset test.
CIP
Tells the operator to apply full throttle in a CI power test.
Confidence Test Error Messages
Confidence test messages are displayed either as PASS or by a C followed by three numbers (#). A C### is an error message
used by VTM repair personnel as an aid in troubleshooting.
If a C### message appears during confidence test or during normal operation, go to confidence test fault isolation, TM
9-4910-571-12&P, for the necessary corrective action.
