Is there a question, Jim? Can you not get them programmed?

FYI: In our 2015, the Silverleaf VMS 645 is able to set up the TOAD's sensors with NO modifications. Just a simple pairing in the DIAG screen.

I did get them programmed using the Bridge.  I tried without the Bridge, no joy, that would have been nice.  Perhaps you are using a newer version of sending units on the tire, mine are the old originals?

Well, interestingly enough, you say your's is a 650, whereas my notes are for a 645; you'd think our dash would be "newer" if anything.

As for the sensors, they haven't changed models. HOWEVER...they DO lose their battery strength; have you bought NEW ones? If not, well it's entirely possible they're dead...or too weak to pair. They normally will only last for 5 years before getting weak; the battery is NOT replaceable on them.

For people who don't know, when 1 or 2 flake out, I say to drive the TOAD up close to the front of the coach or along side and see if the dash picks up all the sensors.

Otherwise, I'd buy a new set from:

I've attached the order form, just in case.
