As some have said, you can do it with LEAFspy Pro under the hidden menu BUT the procedure requires that you fill the four tires to different levels. 28, 30, 32, 34 and start the search and drive for 10 minutes above 25MPH. maybe tomorrow morning I can try.

You are describing the manual reset method and that will not address unregistered sensors

I bought 4 brand new tires and wheels from a 2017 SL that went under a tractor trailer at 1000 miles.

Tires look brand new and wheels as well. I just changed my bald fronts with two of these and now the tire warning came on.

How so I sync the 2 new tires with my car.

I have LEAF spy pro as well if that helps.

Thanks,

UBUYGAS



Well the process would be to go to settings and enable maintenance screen which is not on by default. This gives you 5 dots over the standard 4. Then register TPMS sensors. They will only read when moving so after registering, you will need to drive a few blocks going at least 20+ mph

Settings in the car or LS ?


I don't know of a car that can register new sensors...

Yes, as is the case for most all late model vehicles. Hardly a difficult task, i.e. self-learning, for a well designed algorithm of a TPMS ECU.
Obviously the sensor has to be compatible with the vehicle. It's a standard off-the-shelf system available from many automotive subsystem
suppliers.

How is that determined other than transmit frequency ?
Are there competing protocols in the market ?

The TPMS ECU reads the data stored in each sensor, e.g. the tire pressure, the sensor's ID, the battery status, etc.
Each ECU vendor can design its own algorithm for determining the sensor's position. The frequencies are somewhat
standard as are the communications protocols from each sensor's manufacturer.

Heh. Now where have I heard that before ?

You are leaving me with the impression that I cannot buy a generic TPMS at the right frequency and have much expectation of plug&play compatibility.

Generic sensors or the "universal" type needs to be programmed.

Then you DON'T buy that type unless you have the tool to program them, right? It's that simple.
