"Stored Code" - during a dealer inspection a stored code was found but no operational problem with related code. What gives?

[SmokyMtnsJeepGirl]

Post-purchase, I took my new-to-me '21 JLU Sahara to a local dealership for a full inspection needed for a Maxcare Extended Warranty. (I purchased the jeep from an out of a state Jeep dealership.)
Upon inspection, I was told by my local dealership that I had a "stored code" related to the passenger-side blind spot detection feature. Since purchase, I have never had any problem with the passenger blind-spot detection feature.
The local service advisor said that the code was "stored" and since I wasn't having any current problems it probably corrected itself or for piece of mind I could leave it for diagnostics. Since I had not noticed any issues I chose to forego the diagnostics and the cost for the diagnostics. I need a clean bill of health though to get the MAXCARE warranty so this "stored code" is not excluded as a "pre-existing condition."
What exactly are stored codes and if the issue is functioning correctly how do I reconcile the code with actual functionality?
Of course, I'd rather have a clean extended warranty vs one with a pre-existing non-covered feature.

Leave it for diagnostics if they don't find anything they clear the code and you're good to go.

It's either that or you have an exception on your warranty.

Is it possible that when the blind spot code showed up the dealership fixed the problem but didn't clear the code?
I only ask because the blind spot detection has worked like a charm as long as I've owned it.

If you remove the door, the disconnected mirror will trip a blind spot error The yellow blind spot lights illuminate when you start the jeep as a test No mirror, it will set a code. It Should clear when the doors are put back on, Do your yellow blind spot lights both illuminate for a few seconds when you start your jeep? If so they're testing ok and the code might just be stored from the doors being removed

Here's a mini deep-dive. Hopefully it provides a bit of additional context for you.

I just went out and checked and yes, the yellow lights appear on the side mirrors at startup.
I know the doors were taken off by the previous owner - the bottom bolts on the hinges were gone when I purchased it.
It's not been warm enough here yet to take the doors off.

Thank you! The info was very helpful!
@2timing asked me if the blind spot lights were coming on upon startup and they are. Also, I know the previous owner took the doors off because the bottom bolts are missing from the hinges. He mentioned that would cause the code to be thrown.
Without paying a ton for labor, diagnostics, etc and seeing how they seem to be functioning as they should upon start up, how do I get this code cleared for a clean inspection? Am I just stuck with paying for diagnostics, etc.?
And will I have to clear this code every time after I remove my doors?

if you saw how many codes our Italian vehicles throw just by existing you'd lose your mind lol. my alfa would have 20-25 random stored codes at any point in time. same goes for a lot of our vehicles like the renegade or compass

generally if you aren't experiencing an issue and you've got no warning lights a code can be ignored as erroneous

Unfortunately I can't ignore this one as I am about to purchase a MACXARE extended warranty and with the code still there the blind spot function (and I guess everything that goes with it) will be noted as a "pre-existing condition" and excluded from the warranty.
I drove my '08 Sahara with the check engine light on for 7 years - lol

Sounds to me like you only have one option.

Removing doors could cause that code. Dirty sensors can cause that code.
Normally these need to be aimed and calibrated. Since the Jeep radar is part of the light I don’t think there’s much aiming involved.
Id just clear the code. Go for a drive and see if it comes back. But I have a Autel scanner. If you don’t have one see if the dealer could do it.

 

[JustDucky]

Although I could be wrong (and it would be Jeep's fault) I would think that other scanners would also be able to clear any/all codes, not just the Autel's. iCarSoft being one. Anyone with one, the other or even others could plug in and clear the codes. It doesn't need to be a dealer/shop. A neighbor, friend, other family member, the guy down the street... got a scanner? done in less than 5 minutes.

JScan will do the job at a good price.

It’s fairly common for the blind spot sensors to temporarily fail when driving on a dusty trail. Left dirty long enough results in a code. Normally the code clears after the sensors are cleaned and a few drive cycles, but is stored longer under previous drive cycles. JScan will clean up the codes, but your smog readiness will be reset, requiring some driving for all system checks to complete.

That's not how maxcare works. Pre-existing conditions are for physical damage. We get codes for all kinds of nonsense that we don't act on because they are indeed nonsense. If your blind spot is working without issue it can safely be ignored. Our software error handling is generally horrendous.
