Parameters
dtcnum
The number TermDSM associates with a particular DTC. The DTC
command lists each DTC with its assigned number. This list is also
printed when you make a mistake while typing in a DTC number.
cardnum
Number of the interface card within the DTC to which the device is
connected. The cards are numbered from zero beginning at the bottom
of the DTC.
portnum
Number of the port on the interface card. As you face the back of the
DTC, the ports are numbered from zero beginning at the left of the
board.
Description
This diagnostic cannot test all the functions that are possible with a hood (loopback
connector), since the DTC connection itself cannot be tested without a hood. However,
this diagnostic has the advantage that no cables need to be disconnected from or
additional equipment connected to the port.
When the subcommand is entered you will be asked:
Do you want to stop looping if an error is found (yes/no)?
If you answer yes, the series of loopback tests will stop if an error is encountered. For
example, you specified you want the test to run 10 times and an error is encountered in
the third test. If you answered yes to the above question, the remaining seven loopback
tests will not be run. If you answered no, all 10 loopback tests will be executed regardless
of the results of each test. The following question is then printed on the terminal:
How many times so you want to repeat this operation?
You should then enter how many times you want to run this diagnostic function. Enter a
number between 1 and 65535. The following is then displayed:
Type CONTROL_Y to stop the looping.
Any time that you want to stop the diagnostic, press
[CTRL]-Y
. The diagnostics prompt
will be printed and you will be allowed to enter another subcommand.
If TermDSM knows that this test has failed, an error message will be printed listing the
reason for the failure and how many milliseconds the test ran before failing.
The diagnostics prompt will be printed and you will be allowed to enter another
subcommand.
