This may prove useful if your tps battery is dead and you're out of warranty
http://forum.cog-online.org/index.php/topic,29847.0.html
Good thread, good idea and something that may come in time.
that's an excellent idea :yes: but useless to me now I don't have the gtr anymore :wink: that's the one thing with the gtr that wound me me up "sideways" :grin: the fact that if and when you need a new battery it was off to the stealers to remove £250 smackaroons from your wallet :angry: for the sake of a £2.00 bloody battery. what was kawasaki thinking off when they designed a tyre sensor that when the battery failed you would need to pay for a new full sensor then pay to have it programmed to the e.c.u :angry: bloody idiots... lets hope the idiot that thought of that idea as been "BINNED" and sent to the looney house :laugh:
Can anyone confirm whether the TPS have a 5 year warranty? My front one keeps telling me battery is low..

I spoke to simon chitty at kawasaki customer services about this :yes: he said he would expect the batterys to last 2 years and would be replaced if they were to fail with-in the warranty. after that, it's up to their discretion or if they would offer a discount if with-in "grace period" shortly afterwards!! to be honest it's a really bad design which lets the rest of the bike down.
The irony is that I don't think this is confined to just Kawasaki bikes
in a year or two time TPS is to be compulsory on new cars; no doubt bikes will be close behind- the argument is not just safety but carbon footprint reduction too ( yawn )
My mazda 6 had tps failure due to corrosion of the valve stems; it let go at around a ton. They were replaced under a recall ; eighty pounds each plus the fitting but mazda wiouldn't pay for my fried tyre!!
Because the air was let out so quickly the tps was in effect useless although i did slowto a stop cos i saw the warning light
the RAC chap that came out told me that they were usually useless; most tyres were damaged beyond repair (rapid failure at speed) which rendered the tyre repair kit useless too. My car had to be recovered, the tyre was unrepairable
So it seems that as technology moves forward, the price of repairs does too.
So far i am not getting any low battery warnings on the bike, despite going for a ride in the snow last week

Ok thank you 2kwacks.
I will just have to put up with it until I need a new tyre and try and replace the battery myself..
On the link Teacher posted, one of the guys 'joe in calif' (bottom of first page) said.. "Great ideas for when the unit is out of warranty, when my front sensor was replaced the dealer told me the battery had a 5 year warranty on it. So if the 08 battery goes dead it is covered until 2013. I don't plan on replacing any myself for at least 5 years"
Maybe its 1 rule for them and 1 for us. :wacko:
Hey all, here in Oz at main towns/cities there are some places that (at a price, but low enough!) you can get your tyres filled with nitrogen rather than plain old air. I'm wondering if this, being more inert, might add some life to the TPS's (as tyres warm/cool etc, some moisture will build in the tyre - and this may, if the TPS is not completely sealed, cause issue on contacts and the like). Just a thought!. So far we don't pay for air at the petrol stations, and so for now I've not tried nitrogen, but if it gets to the point where it costs and difference is little, I'd be tempted after I get my tyres replaced to let out all the air and fill them with the good gas.
I'm not sure what the tyre man will say (not the dreaded money-hungry dealer!) if I said, 'hey, by the way, while you have the tyre off do you mind if I just grab that TPS out & whiz home to replace the battery - be back in an hour', while he has a shop full of bikes to do. Solution - get a group of like-minded together & get our own tyre change station between us......
Sooner or later someone will either fit a micro-generator to their TPS, fit a solar cell or 2, or else find some way of beaming power to the TPS.
Batteries is a stupid idea for something like that, even if it is possible to change just the battery.
TPS are a good idea but the companies implementing them seem to think that people will just stump up the stupid amounts of money to keep them working.
I do my own maintenance and will be fitting new batteries myself at the next tyre change. I will also probably be powdercoating the wheels black at the same time as I am sick of cleaning them.

My wheels are minging and been thinking the same thing :yes:
Debs, why do you think that changing the colour of your wheels will help them stay cleaner
Yeah, yeah, yeah I know...only teasing...... :whistling:
In the muck on Deb's wheels I was sure I could see some Pixies :whistling: I bet Geoff can see them as well.

I actually saw Elvis in the ghetto.. does that count? :mfr_lol:
there's a chip shop in the ghetto ?????

the tyre sensor on the gtr is the "direct system type" and in cars the batterys are designed to last 10 years so kawasaki need to take their chicken :shit: design back to the drawing board :yes: my car uses an indirect system but doesn't actually measure the tire pressure. It uses the wheel speed sensor which is part of the ABS system to measure very minute differences in rotational speed between all four tires. When it senses a difference from what a nominally good tire is, it will turn on the tire pressure light. but you will need to check the tire pressure in all tires, as it doesn't indicate which tire is the problem. Once the tire pressure is adjusted and all tyres are inflated to the correct pressure you reset the system by simple holding the control button in on the dash for more than 3 seconds :smiley: it's a simple but very efficient way of monitoring tyre pressure and is maintenance and cost free :clap:

geoff it's really simple to understand :yes: there are 2 types of tyre sensor systems, the "direct system" that is similar to whats used on the gtr and in some cars, and the "indirect system" which is the type that is used on my ford focus titanium model which users the a.b.s system, I'm simple pointing out that the "indirect system" dose excatly what it say's on the tin... lets you know if your tyres loose any air pressure and this system is maintenance free :smiley:

now.. now .. geoff nice try :yes: but we all know, you never had a "scooby doo" as in clue... just in case you never knew what the meant either :whistling: what the hell I was on about :laugh:
I use my TPS as a guide or monitoring device only.
Its wise to check tyre pressures with a calibrated gauge before riding.................like we used to do in days gone by :mfr_lol:

You seem t6o forget that your car has 4 wheels and your bike only 2. :ohplease:

dam.. and double dam!! so that's why when I stop on the bike, I need to put at least foot on the ground.. doh! and your point is? I'm simple pointing out that the kawasaki t.p.s system could have been better designed, I also pointed out that my car use's the a.b.s system to inform me when air pressure is lost in either of the "four tyres" which works fine and dosen't require batteries. but thanks for pointing out the difference between the motor car and motorcycle :yes: I thought the only difference was with the motor car is.. you never got wet when it rained :grin: H0! and the steering wheel :mfr_lol:

My point is that what works on your car with 4 same size tyres doesn't necessarily work on a bike with 2 different size tyres. :smartass:
But surely the system is also comparing relative rolling diameters?Not just individual diameters.
So even if you had a trail type bike with a 21" front and a 17" rear, the system would know the diameters and constantly compare them, it would recognise when that relationship was altered.
Mecki's reasoning is correct here, not possible to use the same system on bikes with possibly different size rims at the front and back never mind different profile tyres and also when the bike is lent over during cornering giving a different sensor reading that would not enable the ABS type sensors to work.
The ABS sensor system only works by counting the revolutions of the tyres and applying the warning light if one tyre is reading a different rpm than the other 3 over a set distance. it cannot tell what pressure is in the tyres!
If you set all the tyres at 20psi and reset the system it would assume that was normal, my car has the same system and seems to bring the warning on when there is a difference of about 10psi.
That said it must be possible to create a self charging unit using kenetic energy from the rolling motion cheaper than the existing price of the sensors, they can make it in watches that never need wound up and casio make solar powered watches which never need batteries, although they may me a lower voltage than the 3v batteries in our TPS's but the technology is already there.
Although it may be annoying having the low battery warning come on I'm afraid it won't bother me to the point of taking the tyres off to replace the batteries, think it will have to wait till tyre change time...

:no: of course not... but I obviously meant the same principle of using the "indirect system" on the a.b.s pick up sensor on a motorcycle front and rear wheel "separately" :whistling: thus... sending "indivdual" front and rear tyre pressure information to the rider!
The abs type sensor system doesn't send pressure information anywhere Dave, it calculates a change in rpm as a result of a change in tyre circumference due to lower pressure in the tyre.

:yes: I gree... but it can still inform the rider of low tyre pressure. I was simple pointing out there's more than one way to skin a cat :smiley: what ever way the dam signal is sent :wink:
anyway.. bollocks to this I've got more important things to be getting on with like sorting out my sock drawer :mfr_lol:

I was thinking the same. Piezoelectric crystals come to mind.
Even replaceable batteries would be preferable, but I guess they make more money selling us new TPS units every couple of years. :death:
Can't believe it but more problems with my 1 year old GTR. Had a magnesium Brown one , that :shit: colour to you lot, and it ran brilliantly for 25,000 miles without a hitch. So traded it for a lovely Green one. Same model of bike, same journey every day, same Driver (but one year older of course). Done 15,000 miles so far, 1 year and 1 month old.
3rd set of pads, second set of discs, tyre sensor flashing, and now exhaust paint peeling off.
Mine was probably built by British Leyland on a Friday !. :2guns:
