Well I finally went out and tried switching the sensor ports it did the same thing, beeping from one side, but not from the other. I have checked all connections made sure they are plugged in and locked, and did everything. I don't get it.
I did what you said BRD also and did the default setup. The ALP doesn't even appear to be updating settings now. Something is strange. Not sure what else to do next.
