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.
