Given your original A pack the only way to verify which fuse is in it would be to drop the pack and open the fuse cover. At which point you might as well replace it even if it is an original unpowered fuse.

Pyro Fuse Fuss

I can't say this enough.
if you get the warning, wait!
There was a bug in the fw that was triggering the alert which cleared after 5 or so days.
My car alerted but I knew it didn't have the fuse as I have dropped the pack to replace contactors. The warning cleared.
I wonder how many of these Tesla have replaced without needing to?

I have simlar age battery back on mine and the service did confirmed that they had internal error and the system should now be corrected. You should get the proper warning when the fuse NEEDS to be changed. The false message was a warning to change it soon.
Just got the repair estimate for the appointment that’s scheduled for 09/21 of $501.60. This includes a $200 diagnostic fee… yet I’m taking it in to them because of the code.. but whatever. Not only that, but Tesla will not honor the 3rd party bumper to bumper warranty I purchased with the car. I love the car, but this has to be the absolute worst service I’ve ever had. And with more people buying Tesla’s from 3rd party dealers, they really should rethink this. Then again, they probably just don’t care.

@Tracy Anderson bring up that diagnostic fee... they don't have anything to "diagnose" as this is a message generated by Tesla based on the age of the pyro fuse installed in the battery pack, and not due to anything the car is detecting. They had that on my estimate, but removed it today when I brought it up to them.
They just finished replacing the pyro fuse, $312 with taxes included.
While that might be true in some cases, we don't know how many that are false because frankly we don't know the parameters for which the alert is suppose to trigger. Similarly, many pre-refresh Model S owners are also getting THC errors related to no feedback of the radiator shutters. We don't know how many of those are actual issues versus how many are a result of a bad patch in the software update that is looking for a non-existent component (as some have theorized). It would be helpful to owners if Tesla was forthcoming with these issues because it leaves us guessing.
The fact that this warning can disappear after 5 days is reassuring. What year and what car do you have?
MX 75D 4/2017 just got the message, so 6.5 years and 44K miles. I'll wait out the 5 days.

I knew it was a false alert as I have previously dropped the pack and had the fuse in my hand.
Sure enough, around4 days later, alert gone.
Tesla are scamming people with this.
We should know how many are false if people wait.
We know the fuse has no data connectivity to the car and its purely time based (as the warning indicates, 6 months left).
I knew my car didn't have the fuse and sure enough the alert disappeared after 4 days.
