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
When this subcommand is entered, the following question is displayed on the terminal:
Do you want to stop looping if an error is found (yes/no)?
If the answer is yes, the series of loopback tests will stop if an error is encountered. For
example, you specified you want the loopback 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 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 is then printed on the terminal:
Please put a loopback hood on the Port, before answering
the “How many times?” question. (TDSM 113)
How many times do you want to repeat this operation?
At this time, go to the DTC and connect a loopback hood to the port. Then return and
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.
