STC14Jim,
When you talk to Autel see if there is a limit on how many programming changes the MX sensor can support.
Could be a lot of attempts at finding the protocol for newer C14 sensors (if there is a difference).
Also would be interesting if the newer C14 sensors wake up to the 125 KHz interrogation signal.
https://www.tomorrowstechnician.com/tpms-radio-frequency-theory-and-operation/"The majority of TPMS sensors are activated with a low-frequency signal (125 kHz) coming from a TPMS tool. This radio signal varies from vehicle to vehicle (some require more power than others) and forces the sensor to transmit. This signal excites the antenna coil in the sensor."
The Kawasaki sensors are made by LDL ( French Company ) as well as sensors on Honda's and Triumph's.
My guess is that all these sensors use the same protocol - why would LDL go to the trouble & expense of using different protocols in each make ? But some might use different frequencies. 315 MHz is most common in the US ( but not mandatory ) and 433 MHz is most common in Europe & Asia.
My bet is the protocol used is decided by LDL , not the various manufactures ( make ) that they supply to.
It looks to me like LDL has a corner on the motorcycle market.
I read an article that implied a universal sensor like the AUTEL MX sensor transmits all possible protocols, but I question that idea since it would drain the battery quicker/sooner : more transmissions = less battery life.
I think I may give the AUTEL tech line another call to verify that.
