I think its just below the valve, but you have to take the tyre off to change it.

The TPS giving a low battery warning is a common fault. The battery is supposed to last five years and I don't believe you can replace the battery standalone. The whole unit needs to be replaced and sync'd with the ECU which only a dealer can do.

The good news is that its covered by warranty so shouldn't cost you anything.

You cannot change the battery, you have to replace the all sensors. Even when replaced do not be alarmed if it shows the message "low battery" in cold weather, it should be back to normal once tires have heated up.

+1 to above, it is a tab-welded CR2032 that is soldered to the circuit board inside the TPS.  They make it that way because the forces inside a rotating tire would be beyond any replaceable battery configuration.  Sucks, but kind of makes sense.

When I wrote you cannot change the batteries, this is going by the book. Some of my buddies in the US have replaced the battery but their soldering skills are excellent, for myself I follow Kawa's instructions and replaced the whole sensors.

Surprised they don't use a dyno concept to power the TPS.

When they went on my old model I quickly realised what a pain in the butt these are going to be when they do fail. In the first instance the battery can't be replaced. Secondly, there are no third party versions so you're forced to go to the dealer. Even if there were third party ones available, you'd still have to go to the dealer to get them mapped to the the ECU.

The dealer wins unless someone can figure out how to replace the battery.

I just had my front TPS replaced under warranty. Low battery error in cold weather.

Mines doing the same !!!!! front tyre low battery !!! Its only a cr2032 keyfob battery so i have Araldited a piece of wire either side of the new battery left it overnight to set solid , just checked voltage with a meter which was 3.2 volts at the end of the wires so no poor connection and i am going to solder it to the circuit board leaving the existing battery in place (in series) and i am going to to secure this to the tps with a few cable ties !!! let you know how i get on soon guys!! ;)

surely they would only be coverd with-in the standard 2 year warranty! not for the 5 years there suppose to last!

 :) well today when fitting my new tyre i took apart the TPS and managed to pry off the old 2032 battery and resolder a new one in place  ;D Only problem i had was i had to really sand down the new battery to make sure the solder would stick to it and also soldering it in the right position !!! put it all back together and works within about 50 foot !!! well impressed as i went to the dealers and the sensor was about £190 and then fitting and coding to the bikes ECU !!!!!! So it pays to have a go because at the end of the day it was knackered anyway  ;D

I'd be interested in how you did that. Did you take any pics?
Title: Re: low battery on tps
Post by: mark.fozz on February 04, 2011, 10:38:25 PM
Unfortunately i didnt take any pictures but it wasnt that difficult. The TPS was removed using a 5mm allen key and theres a little t5 (i think) torx screw hidden under a sticker on the sensor which you remove and the casing of the TPS just pries apart .I just used a very small flat bladed screwdriver to break the 2 small spot welds on either side of the battery and cleaned the 2 prongs with emery paper . With the old battery removed i tried solder on these terminals which stuck very well !! So i roughed up the new CR2032 battery both sides using the emery cloth again and applied 2 small blobs of solder to the battery which stuck aswell  ;) . So after aligning the battery in roughly the right position i soldered it on . You have to make sure that its in the right position because you have to make sure it fits again into the the little plastic box it came out of ( took me 3 attempts) :P
And low and behold it works fine !!!!!
;D

How did you get the solder under the tab? If you look at the picture the solder is between the battery and tab.  Was it solder onto the battery, place tab, and reheat solder?

 ;D It was !!!  but i only had a gas soldering iron so i had to use a blow torch to get it red hot and did it that way !! Hope this helps

That does indeed. Mine have been replaced under warranty but its good info to have.

Had the bike in for service at Cradley Kawasaki at the weekend and i mentioned that the low battery warniong has come one once.

They are going to replace them under warranty

Warranty runs out with the bike. I got mine replaced under extended warranty. There's a little known law called fit for purpose that you could use to argue your case, esp if Kawasaki say they should last for five years with average mileage.

The low battery warning will come on in winter and after a few miles disappear. It's if it come on in summer that you need to be worried. If your bike is under warranty get it replaced even if its just for peace of mind.

I only Bought mine in December a 57 plate with 1750 miles on it and mine was like this. Starting from cold it took about 3 to 5 miles to start working which was starting to do my head in as other things will not display untill this goes off . When i took the TPM apart i put a volt meter on the battery and it was indeen flat, i think it was 0.25 volts and it is a 3v cell (but would come to life after a goos run??? ) once i replaced the battery it works probably within about 10 seconds ish now ....well chuffed  :) ;) ;D

Could be the previous owner has had them changed. TBH, this issue can be categorised in a few ways:

1. Those that have a TPS failure
2. Those that have a low battery warning in cold weather
3. Those that have a low battery warning in all weather conditions

If its 1 or 3 you need to get it sorted. Cold weather isn't going to affect it for too long. Once heat starts getting into the tyre after a few miles the message disappears. If you have warranty then best to get replaced
