Troubleshooting Tip:
Even if you are not planning to use the CV Lock feature, it can still be
accidentally activated by inadvertently programming CV 15 or 16 with a
non‑default value. If you have a decoder that is otherwise working properly
(i.e., making sound and responding to throttle commands) but has suddenly
stopped accepting CV changes, then first run through the procedure under “If
you Forget the Lock Code” to determine if the decoder has been locked.
Resetting the CVs or Starting Over
Occasionally, something goes wrong and the SoundCar DSD will not respond
as expected. Usually this is caused by one or more CVs being programmed
to an unacceptable value. CVs can easily be reset to their factory default
values as follows:
1.
Place the model on a powered section of track. Using either Service
Mode or Operations Mode, program CV 8 to 8, or CV 30 to 2.
2. If the model is already on the mainline, cycle power to the DSD by
turning power to the track off and then back on again.
Note:
If you have a SoundTraxx CurrentKeeper™ or other device
intended to maintain power to the decoder, remove power for at least
2 minutes to ensure that it is fully discharged.
3.
If sounds start immediately after power is restored, the decoder did
not reset. Repeat Steps 1 and 2.
4.
Approximately 6 seconds after power is restored, startup sounds
should begin, and the headlight and backup light (if connected) will
blink 16 times, indicating that CVs were successfully reset.
5.
Your SoundCar DSD should now respond to primary address 3 just
like it did out of the package.
6.
If you cannot get the decoder to reset, make sure it has not been
inadvertently locked (see “Locking and Unlocking CVs” for more
information).
