a. Error messages. Error messages indicate the VTM needs additional or corrected information before testing
can continue or additional procedures are required.
All error messages are displayed as an E followed by three numbers (for example, E003).
VTM has been asked for information that it does not have. For example, you have
requested the vehicle/equipment ID and it has not been entered.
A test number which does not exist has been entered on the TEST SELECT switches.
The required transducer is not connected.
Test number wrong for DCA connected. This can occur if test selected does not apply to
the class of vehicle/equipment under test or if the DCA harness does not have the
No longer used. If message appears turn in test set.
Required offset test was not performed.
The VID number and number-of-cylinders information entered do not agree.
VTM is not receiving required voltage signal for selected test. This message can occur on
tests, 14, 15, and 72 through 79.
VTM is not receiving engine speed signal. This applies only to engine power test and SI
full power simulation.
A wrong VID) number was entered. The VTM will only accept numbers between 01 and
99. If E010 is displayed when the VID entered was between 01 and 99, it means that
the VID) does not agree with the identity of the DCA harness powering the VTM. The
VTM will accept this, allowing you to power through the DCA while testing another
Throttle control was operated incorrectly. It was taking too long to accelerate or decelerate
during power test.
The SI ignition adapter, TK item 30, or CI pulse tachometer, TK item 34, is missing or
is not connected to the VTM.
VTM is unable to use data received.
The wrong number of cylinders was entered.
No longer used. If message appears, turn in test set.
