Lesson 3/Learning Event 4
An error message indicates that the VTM needs additional or corrected information before testing
can continue, or that additional procedures are required.
Error messages are displayed as an E followed by three numbers (for example, E003).
Error Message Displays
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
The required transducer is not connected.
Test number wrong for DCA connected. This happens if the test selected
does not apply to the class of vehicle/equipment under test, or if the DCA
harness does not have the required transducers.
A vehicle identification (VID) number or number-of-cylinders information
has not been entered. It can also occur if a VID has been entered that the
VTM has not been programmed to recognize.
Required offset test was not performed.
The VID number and number-of-cylinders information do not agree.
VTM is not receiving required voltage signal for selected test. This message
can occur on tests 14, 15, 19, 20, and 72 through 79.
VTM is not receiving engine speed signal. This applies only to engine power
test and SI full power simulation.
