Determines if a specific port is functioning properly without
disconnecting the device from the port.
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.
