As stated, the aftermarket and OE systems should play nice side by side. They should be on difference frequencies and shouldn't even see each other.
The OE sensors broadcast the whole time they're rolling down the road even with the vehicle off, I've often wondered why there isn't a system that can read the OE system as well as the aftermarket.
