Or it means there was a code at one time, it got cleared on it's own, but the 1693 was left behind.
Autozone should be able to see if there is another one present, or clear the 1693 for you.
As long as you aren't seeing any problems, go for it.
If you are seeing problems, there are some codes that Autozones scanners can't see,
only the Dealer's fancy schmanzy proprietary code reader can see.

I have a OBDII code reader and it only retrieved a 1693 DTC.....I cleared it and it never returned.

How about this reasoning:
The Dodge PCM is ODBII compliant, meeting the passenger vehicle requirement.
The Cummins ECM isn't so much, as it's a medium duty engine, not a "passenger car" engine.
You connect your basic code reader to the connector, this connects it to the PCM.
The PCM is responsible for storing and passing all the codes thrown by the myriad of computers controlling everything from the airbags, antilock brakes, automatic transmission, instrument cluster, lights, etc.
Sometimes the ECM doesn't communicate well with the PCM, hence the mysterious 1693 code:
"Hey, ECM here I have a code but you won't understand it, so lets just say I have a code and leave it at that."
Same communication errors might exist between the other computers and the PCM.
Now you have the Dodge DRB Scan Tool, specifically made to communicate with the PCM as well as the ECM, even the individual computers themselves, not relying on the PCM to translate it all.
Hence it's prohibitive cost (thousands of $$) compared the the relatively cheap off the shelf code readers (couple hundred $$)
I sleep better thinking that's how it works.

you can go to autozone and have it read there...
But I do have a nice neighbor that lets me barrow his code reader when I need it!
But this a just a reminder that not all of us have a Autozone in the state.

....Well, a good nights sleep is important!
To some degree, that does make sense since the code reader only communicates with the PCM and not the ECM...
