OK guys, I did some research and come back.
I checked the coverage with the Autel I plan to buy, the TS508, against the current cars I have for now.
2 of them 315 Mhz, ODB relearn
1 of them 433 Mhz, Auto relearn or ODB relearn
None of the vehicles seem to care or have indication of the wheel positions.
So I wanted to do 2 things I can think of right now
1) scan the existing TPMS sensors and write down their IDs. if/when the TPMS fails in the future, I buy the autel TPMS sensors in the correct frequency and program them with the set of IDs, the vehicle won't need to relearn them. Although, it seems like the 508 can do a ODB2 reset and let the vehicle start learning NEW IDs, if for whatever reason I lost the IDs.
2) I want extra set of wheel and tires for one of my vehicles (say, snow tire), I want to get 4 Autel TPMS sensors and program them with the same IDs that as the first set.
When I swap the tires the vehicle won't notice any difference.
Can I do the above with the TS508?
Yeah I understand I am locked into the Autel sensors only, but they are not too terribly expensive.
