Who knows, it might be one of those little secrets that very few people know about. Or does it damage the transmitter forward? Here is a scenario... People take their cars in to have the TPMS light taken care of, tech does this mumbo-jumbo and when your called, a whopping bill confronts you. You pay it (because you want your car back) and drive happily ever after (until the next glitch)...
I would just do the TPMS disconnect at the module near the dome light. I check my tires occasionally, as I don't trust some things to little pressure sensors that do not have replaceable batteries in them (not to mention the cost to dismount/replace and such). Just another money pit that generates big bucks for mechanics, and just as useless as a dealership with an untrained XF tech replacing parts until you go away (type of troubleshooting style).
