My TPMS went bad, not just low battery. I try Mazda 3 TPMS on my front wheel and it works.
1. Get Mazda 3 TPMS from eBay $15, P/N BBM2-37-140B
2. Read TPMS ID by autel maxitpms pad
3. Register TPMS ID by KDS3
4. Install TPMS
Done
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

Wow thanks for sharing especially an alternate and less expensive TPMS!
Curious though to get the TPMS ID from this device Autel MaxiTPMS pad-- what is this and what's the cost of that since that will probably need to be factored in?
I'm assuming the Mazda 3 TPMS is similar in size and no issues mounting into the C14 wheel. Hopefully you can share pictures of said device and Mazda TPMS.

How did you figure that out?!
This gives me an idea. I have my old TPMS sensors and a benchtop power supply. I could power my old sensors, clone the ID to a new one and it SHOULD work. Interesting...

The Autel TPMS pad is less than $70 from Amazon. And while Autel sensors are $32 a piece, that may negate needing to take the bike in for re-programming if you have the old sensors.

Are you kidding? You mean like this:

Seriously? $42 for FOUR of them? And they work? This is *MAJOR* since they cost a fortune from Kawasaki. Looks like they are always sold in 4's but at that cheap you can store the other two in the freezer for future use. How in the world did you discover this???
But why would you need to buy the $52 "Autel MaxiTPMS PAD TPMS Sensor Programming Accessory Device Tire Pressure Tool"? Wouldn't the ID be printed on the sensor? It looks like the pad will create a compatible ID for the appropriate vehicle, so it might be required.

Maxtog,
The Autel pad is for cloning the sensor ID, so that you don't need to take the bike in for programming. As far as the bike is concerned, it thinks it's the old sensor.
I've got stuff arriving today. If it works, I'll post about it in a new thread. I'm being quick about it because I've already ordered a new front tire. We shall see.

Oh! That would be even MORE awesome.

Great! I can't wait to see/hear the details. At lot of us wish this stuff were around forever ago.

So I successfully cloned my ID to a new sensor. I’m going to roll the $30 dice and have it installed on my front tire when I change my front.

Yes, I use this TPMS
Autel MaxiTPMS PAD is to read ID on new TPMS which will not come with ID printed outside.
Any TPMS programmer should be able to read ID from this TPMS.

Just want to save some money... haha..
With programmable TPMS should work, I bought Mazda TPMS long time ago, I can register ID to C14, I never read PSI from this sensor by spinning it, but C14 shows 0PSI when I wake TPMS by tool, so the only problem is that I cannot make sure how to wake TPMS without tool.
This time my C14 TPMS dead, just try to install Mazda TPMS and it works...
-

You can turn C14 key on, wait for 2 mins, wake TPMS by tool or read this TPMS by tool.
C14 should alert the Front tire low pressure.
-

Does the currently installed sensor weak battery?
When I bought my bike, it came with the original sensors, not installed. I got some “universal” TPMS sensors that were $30 a piece. There is no currently installed sensor. I believe the sensors have been dead so long that there has been component failure. There is the ID tag on it, though.
I’ll try the two minutes, then wake the sensor tomorrow before I head to work.
-
Thank you both for the updates!
How easy is it to replace the TPMS battery? And what size/type? That was the problem with the 2nd gen C14 TPMS where it was difficult to replace the battery compared to the 1st gen TPMS.
-
Subscribed to this for future needs.
-
So turning the bike on, waiting, then waking the sensor yielded no results. I'm going to install the sensor anyway. If still nothing, then I'll have my Kawi dealer program the ECU for the sensor. It's possible the sensors I got weren't the original ones to the bike. You never know. I am not giving up, though. My new front tire should be here today. I might get it installed this weekend. Dunno.

May I know how do you program universal TPMS? Program it as Mazda3 model?
Another debug suggestion.
1. Copy your rear wheel sensor to universal TPMS by choosing Mazda3 model. (Rear sensor works when you are riding C14 right)
2. Turn on C14, wait for 2 mins (service manual says 3 mins), Wake universal TPMS and you should see rear tire low pressure.
a. If you see rear tire low pressue, Front TPMS ID in KIPASS does not match with the sensor come with your C14.
b. If you see nothing, we sould figure out what happens on your universal TPMS and programmer.
BTW, I just come back after 100mile riding, Mazda3 TPMS working no problem.
If you are in SF bay area, maybe I can help to read ID, my KDS3 SW was old, not sure if I can read newer model after 2011.
-

Good for you for offering to help if people are in the area. I don't think BigRed is, but it's good to offer.
-
Thanks for the offer. I'm not in your area, though. I'll get it figured out, one way or another.
-
Definitely of interest to me.
My '12 is starting to show a Low TPMS Battery indication and I may try this for an experiment. I recently came into possession of a KDS3 and can go the ECU registration route if need be.
Question about the Autel MaxiTPMS pad: Which OSes are supported by its software?
-
I believe the pad only supports Windows. Worked fine on my Windows 10 Surface.
-
Ok I'm going to try the Mazda sensors and Autel pad. Figured I can get the ID from the stock sensors before they go completely dead and change them at the next tire change or do the zip tie tire bead break and change them right away.
-

I thought you just had to read the Mazda sensors to get a number to program in with the KDS?
-
I guess Autel Programmable Universal TPMS also works
Just copy from Kawasaki TPMS by choosing Mazda3 model so don't need to modify ID by KDS3
Will try when I have chance.
-
Is there a Mazda 3 sensor of the "sled" style (like the C14 uses) - rather than the "flag" style like I'm finding most places online? The latter is made to lie parallel to the tire tread when used in an automotive rim. Putting them in a Concours rim is IMHO cutting tolerances a mite too close, as they'll protrude out of the rim well and may be damaged in the event the bike hits a large obstruction.
-
My understanding is that you clone the Kawasaki IDs into the Mazda 315MHz sensors so there is no need for KDS.
Also wonder if the universal type that is a "sled" shape would work with the Autel programmer.
Hmmmm
I thought you just had to read the Mazda sensors to get a number to program in with the KDS?
-
I dunno is there's a sled one that'll work. If anyone finds one, I'll be willing to give it a try. I've got my new TPMS programmed and I'm going to try to get it installed this weekend. Lots of projects at home.
-
What was your procedure?
Just looking for the order of the steps, etc.

The OEM sensors I have (which I still don't know if they're the original sensors for the bike) had the ID# sticker on them. I used the Autel pad and programmed the ID into the universal Mazda compatible sensor. Then I'll have the sensor installed with the tire.
-
So the Mazda sensors are if you have a KDS.
I am trying to get the Autel MaxiPAD to read the Kawasaki (Schrader) sensors but it has not worked with the bike on for a few minutes.
I need to take the bike around the block to get the sensors turned on (or they have gone dead and are not reading).
I did some Googling and the Mazda (Continental FCC ID KR5S180052015B) sensors have a different emissions designator than the Kawasaki (Schrader FCC ID MRXKAW4) OEM sensors.
Mazda = Emissions Designator 138KF1D. 138Khz FM modulation
Kawasaki = Emissions Designator 99K0L1D 99kHz Pulse Width Modulation
Hmmmm....
My understanding is that you clone the Kawasaki IDs into the Mazda 315MHz sensors so there is no need for KDS.
Also wonder if the universal type that is a "sled" shape would work with the Autel programmer.

You don't need to ride C14 to turn on TPMS, Kawasaki TPMS can be waked up by Autel MaxiPAD, just place it close to sensor and test it, you will get ID form sensor.
-

I thought the sensors (Kawasaki, anyway) went into deep sleep and would not respond to anything until the motion sensors physically activated them. If it had to "listen" for a signal all the time, I would think that would degrade the batteries pretty badly.... especially since in normal operation, I thought they never listen, only transmit.
-
I will try to wake the sensor with the pad again after the F1 race and then do a ride around the block if that doesn't work.
I wonder if the Kawasaki sensor uses a "roll switch" to turn on.
(from Wiki)
The acceleration sensor may be a simple switch rather than an analog transducer (accelerometer). This is usually referred to as a roll switch. The acceleration sensor allows the TPM to be placed in a low-power communication device mode, when the vehicle is stationary which can extend the battery life. The advantage of a roll switch over an accelerometer is that the switch is purely mechanical and doesn't use any power to take a measurement.

No go on the Autel Maxi Pad reading the Kawasaki sensors whether I just turned on stationary or rode the bike (pressure di display on dash after riding). The Ebay Mazda sensors and the other vehicles in the garage read fine.
Stumped in Utah.

Dropped my tire off today for install. I’ll have it back tomorrow afternoon.

What protocol did you use to try to read the sensor?
-
I used the Mazda 3 setting. This bike is a 2010 model and I wonder if that LDL Technology sensor doesn't support the 125 kHz wake function.
-
Maybe. I couldn't read mine either, but I think that's because they'd been dead a long time before I tried to power them back up. I'm using the ID code on the sensor itself to program the new sensor. If the bike doesn't see it, I'll take it down to my Kawi dealer and they'll hook the bike up and check the programming.
-
Holy $h!tballs!!! It works! I took the sensor number off of the OEM sensor and programmed the Mazda sensor with the pad!

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.

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

It CAN transmit most protocols. Once you program it, it only transmits the one you've selected.
-
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."

Just want to put it out there again, if anyone has a newer model sensor, I'd love to borrow it to try to ping it.
-
Is there anyone local to you that could ride their bike over to get pinged?
You don't need it removed from the rim do you?

-
No, I don't need the sensor removed, but I would have to know someone who had one. Not much of a social rider, so I don't know any newer gen C14 guys. Heck, I only sorta know one other older gen guy.

STC said: My bet is the protocol used is decided by LDL , not the various manufactures (make) that they supply to.
Only the early version of Kaw TPMS sensors were made by LDL as we know - the ones with fairly easily replaceable batteries.
A few years ago I 'played with' a couple different LDL sensor for non-Kaw bikes using 433MHz. I have KDS and entered the ID number into KIPASS - they did not work. I contacted LDL in France to ask why. They graciously replied by saying that the 'baud rate' - (the rate at which information is transferred in a communication channel) is different.
-
Freddy : Do you know who makes the newer ( potted ) sensors ?
And do you mean the 433 MHz sensors wouldn't work in a late model C-14 or and early model C-14 ? I would think the later model sensors would also operate on 315 MHz so a different immobilzer/TPMS module wouldn't be required. If so, I'm not surprised the 433 MHz sensors wouldn't work. But I don't think it has anything to do with the "baud rate".
-
The new sensors are 315MHz sensors too so there is no 433 MHz issue. Otherwise any old sensor bike would be out of luck for replacement or the KIPASS ECU would need replaced to accomodate the 433 MHz sensors.

BigRed :
A guy ( T800XC ) on the Triumph Trophy Forum has got the MX sensor to work on his Triumph but he said the stem diameter of the MX sensor is different than the Triumph stem diameter.
Is this an issue on the Concours ??
-
STC14Jim,
When you talk to Autel see if there is a limit on how many programming changes the MX sensor can support.
SNIP ........
A guy on the Triumph Trophy Forum ( T800XC ) has progrmmed a MX sensor many times w/o any problems - so apparently that's not an issue.
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."
BTW, The short coil inside the sensor is used to transmit the 315 or 433 MHz. The 125 KHz receiver just uses a tank circuit to tune to that frequency. At that lower frequency ( wavelength is about 2,400 meters ) an antenna isn't practical. The signal strength is high enough at 125 KHz for a tank circuit to work just fine.
-
Yep an antenna for 125Mhz would be kind of hard to package in the sensor as the wavelength is over 2 km.
Also you wouldn't want an etire garge of vehicles to respond to the inquiry signal for the TPMS. :-) so a tank circuit is sensitive enough.
I'm just happy that Freddy and Big Red have found an answer to dead sensors that doesn't cost hundreds of dollars and a dealer trip.
Easily available too.
-
+1 for sure !!

Is this an issue on the Concours ??
The metal stem MX sensor fits perfect.

That's very good to know - thanks for your reply.
Just saw on the Trophy Forum T800XC is going to fit a AUTEL MX sensor to a Triumph rim today and test the sensor on the bike.

This is the id I got using this tool. I had to choose a vehicle so I chose the Mazd ::)a 3. This is the old style. I could not get a read on the front.. i tried warming up the tire thinking the battery may be low but could get nothing. The front is the later style. Not sure if I have learned anything
-
This is the number on the sensor
-
KZZ, so you're reading the sensor you took the pic of and it's transmitting a different ID code?
-
Yes. I tried to read it again later, twice. I got the pressure but no temp or id.
At this point I am going to have a autel sensor on hand when I pull the front wheel for a tire change this spring and Hope I can
Pull a number from it.

The 315mHz ID is supposed to be the one that is programmed into the bike. I just went back and checked mine to verify. I would try the code on the sticker first, then if that doesn't work, try the one you pulled with the scanner second. Upside is they're reprogrammable, so nothing really lost.
-
Yep, thats my plan. The one with the sticker is the old sstule sothat one is good. The front one is the new style so I hope I can get a number off it. Wished I would have looked at it before. .Thanks
-
Mystery solved! The old sensor was in the front, so the id I had a pic of was for the front not the rear. My reading may be correct!
I pulled the tire to the side and removed the front today. Installed a new battery and tested it with the twirling method. Autel is on the way. Plan is to program it to the front and then test. If it works I will have a backup. Sorry for the confusion and thanks for all the help.
-
Awesome. Hope it works well.
-
Keep you posted Red. Thanks

I put a new battery in the sensor. I could ping it and read it but I could not copy it to the Autel sensor. Took the machine home and updated it (my buddy said he has had it for awhile). Reread the stock sensor and copied to the new in a minute or two! It was so fun I rewrote it to the rear sensor. Not able to ride yet but I think I will be good to go.
I didnt realize that you dont need the bike on or even be neat it to ping it. This means if you have your sensors out and know someone in a tie shop you could just stop by with the old and new and get them programed.
