It states clearly that the operator of a tire store can delete the TPMS if it was faulty when it entered the sop. He can,.. and it specifically states that he ca, remove all the TPMS sensors and replace with standard rubber valves if the sensors were faulty upon entering his shop. He just has to annotate it. Rip out all you want,. legally he cannot deny you service for this. Me?.. I went and spent about $150 and bought two tools,.. one reads/activates the TPMS sensors and tests them. The other plugs into your OBDII port and programs in howver many sensors you want and the pressure values. If it had not crapped snow on us,.. This is the tool I would have used this weekend to delete my spare from the On board computer as i removed my stock spare and put in my 285/17 BFG.. but had to air it down to make it fit (I always have a compressor to air it up).
