Fantastic Big Red

Thanks

Where are the I'd numbers on the new style? Just curious . I will check mine out next tire change. Hats of to those that made another option possible.

It looks like they may have hid it in the barcode. There's no hex number anywhere from the pics I've looked at. However, if you disregard the first 4 digits of the barcode, you do end up with a 8 digit hex number like the old sensors. I'd love to mess with one to see if I could read it and compare the transmitted hex to the barcode. If someone has a new model TPMS with a battery going bad that I could play with, let me know.

My concours don't read Mazda TPMS by spinning on bicycle wheel, but reads after install on my front wheel.
Maybe spinning + tire pressure can wake TPMS

Did you have the engine running when you tested the sensors. I noticed on my 2010 it wasnt reading just spinning the wheel, but starting the engine it read ok.

[Big Red]

If I put it on the center stand, key on engine off and spin the tire mounted, it reads. Doesn't really matter, as I was trying to prove it before installing. Didn't matter as it is verified to work.

The Autel MX3 TPMS Sensors are tiny compared to the stock or other OEM Mazda sensors. That should help minimize the centrifugal weight & the balancing of the wheels with less weight.

[Big Red]

I've been rolling around for about 3.5 months, and they're working great. They read about 2 psi low, but it's plenty close enough.

Waiting for new tire time, soon.....

[BruceR]

Anyone know a good technique to pinch a tire bead?  i'd like to be able to remove the sensors without dismounting the tires (if possible).

Haha.  I was trying to complicate the issue.  That will be easy enough.  My bike still has the original '08 sensors.  I don't remember what a good tire pressure reading looks like anymore.
Good info in this post.  Thanks for doing the legwork on this.

Just mounted up some Dunlop Mutants and changed out the sensors for Autel MX programmable sensors. They work just fine with the Mazda 3 protocol and the Hex code was on the original gen1 sensors. Easy peasy

[deepseamdv]

What are you planning to do with your old sensors? I’d like to get them for some testing if possible.

[dbird29]

They are 1st gen from 2010 but I have no real plans for them after I see if the programmable ones keep working. Which I'm sure they will..

When i talked to the guy at AUTEL technical help he told a new AUTEL MX "universal" sensor don't come programmed with an ID.

He also said they don't support LDL sensors because AUTEL doesn't support motorcycle applications.  So LDL must have a corner on the motorcycle market.   I know besides Kawasaki,  Honda and Triumph uses LDL sensors.   

He also said when programming a new AUTEL MX sensor besides programming in the ID,  you are also setting up the new AUTEL sensor to conform to a certain protocol so that's what needing to tell the MAXI PAD what make & model is all about ( as has been explained previously ).

I have an issue with my 16 Tacoma with a sensor gone bad.  Fine in the summer months but once it gets cold it flakes out (much like me).  I bought an Autel MaxiTPMS TS408 along with an MX universal metal valve.  They offer a rubber MX valve as well.  The claim is that you only need to stock two types of sensors.  I bought their metal one for the Tacoma.  I went in through my OBD2 scanner (Carista) and documented the sensors in the computer.  I then used the TS408 on each wheel to see which one was partly dead.  All wheels replied except the left front and by process of elimination determined the id of the offending unit.  I programmed the MX metal sensor with the id of the failed unit.  I'll be taking the truck in on Tuesday to get the tire people to change it out.  I don't have any way to break the bead on the tire to put it in myself unfortunately.  I don't see why the TS408 wouldn't work on a C14 as all I need to do is put in the Mazda year that works. 

[Big Red]

I'm reasonably sure it WILL work. It's just a matter of finding another compatible protocol. I find it hard to believe that Kawasaki would go to a completely unique standard. It just doesn't make sense when there are so many decent ones out there already. Just a matter of sitting by a working newer model sensor and pinging it with a bajillion protocols to see how it reports back.

[VirginiaJim]

So there are several considerations when working with these sensors...  ID, Frequency, and protocol ?   The MX sensors will do both 315Mhz and 433Mhz.  My TS408 needs an input of what vehicle you are doing.  I guess that's what determines the protocol.  Kawasaki should not be doing something completely unique.  Totally unlike them.  They use other manufacturers stuff.

[VirginiaJim]

I went back into my TS408 and looked at the settings for a Mazda 3.  There are 7 broken out by years from 2004 to 2021.  2014 through 2019 are labeled indirect without a frequency designation.  They do have a 2007 through 2009 setting. 


When programming a MX sensor for my Tacoma it didn't really ask about year but I was in the 'last' test section for my Tacoma.  Now that I'm looking at it again I have these options.  Scan all sensors (which I did).  Scan a single sensor, program a sensor (which i did yesterday), Relearn procedure, and sensor information which breaks down further to OE and MX.  Nothing on MX but OE has the following:  Manufacturer (Pacific), OE Freq (315Mhz), Relearn type (C), OE part number (4260748010), Number on Sensor (PMV-C015). 


I'm just bringing this up to just add more information concerning the sensor.  I know I would love to scan an OE for the Kawi just to see what comes up.

[STC14JIM]

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.

EDIT :  Called the AUTEL tech line and the guy said " No, once programmed the MX universal sensors only transmit 1 protocaol not all possible protocols".   That makes sense to me, as far as conserving battery life.  He said the MX sensors battery should last about 7 years.  They are epoxy potted so a new sensor would ahve to be bought when the batteries are depleted.  For $30 a pop I don't see an issue with that.
