It is NOT an individual LEO thing, it's a company thing. It is how Lo-Jack works. It works the same in Sacramento as it does in New York City, and the alphanumeric code is only activated when the vehicle has been entered into SVS. Even if a code is accidentally triggered, absent a paired stolen vehicle report in SVS (the national stolen vehicle database in NCIC), it would not come back as valid and there would be no reason to try and triangulate ... not to mention they would not know what they are looking for.
If so, it is as I previously mentioned, it is a code that is so much meaningless gobblygook, or, it is a code of another stolen vehicle (which would seem pretty odd, but would also be a vehicle with a different description and likely would not result in your vehicle being stopped). It would also run out of juice over time. (Yes, they can lose power when they have been activated.)
And in those parts of the country, they would not even be able to see the errant device's code, much less act on it.
Many departments have gone away from it as it does not seem to be nearly as popular as it was a couple of decades ago.
I based my entire post upon this email I received.
"Hello
This is a follow up to the voice mail message I left on your cell phone just a little while ago.
This truck which is registered to your company was equipped with a LoJack stolen vehicle recovery system in 2008 at the request of the trucks first owner.
Something has affected the unit in the truck and it is now turning itself “on” and sending its homing signal to the police as if it were reported stolen, which of course it is not.
In order to prevent you or whoever drives this truck from being contacted by law enforcement and to keep this unit from sending any more false alerts to law enforcement please contact me at your earliest convenience."
