Honda Jazz - TPMS warning light

Poulgorm

A relative of mine has a Honda Jazz (bought new - 2017). She is annoyed with the tyre pressure warning symbol coming on - I check the tyres, reset the system (through the menu): the warning symbol stays off for a few days and then comes back on.

The main dealer (where we bought the car) has reset it a few times, but each time it is only a temporary fix.

Quite frankly, they don't seem too interested in the problem

I assume it is an indirect (ABS based) system - it gives no indication of actual pressures, or which tyre is causing the problem.

Any ideas, anyone?

Would this warning symbol be a fail, in an NCT test?

Yes, its a malfunction indicator in any car registered after Jan 1 2015

Are the tyre pressures ok when you check them? Does it have a spare, does that have a TPMS sensor, have you checked the pressure in that?

Could be the battery gone in one of them, you would think the dealer would have hooked it up to the computer to see which tyre it is and next step would be battery replacement (if it's one that can be replaced), then if that fails sensor replace and recode new sensor to the car.

Easy reset AFAIK ,on you tube or go to a the honda fit forum,I'm on my 2 nd import honda, All the relevant information is there, worth spending an hour or so

It’s a 2 year old car on warranty with a fault. It’s up to Honda to sort it out. OP shouldn’t have to put up with that.

Of course not ,but it makes sens to learn about ones motor, warranty doesent last forever

Yes, I check the tyre pressures - no problem there. I am fairly certain that the Jazz does not have pressure sensors fitted to each wheel - it operates via the ABS system. If a wheel is turning at a different rate to the others, the ABS system detects it and triggers the low tyre pressure symbol on the dash. No batteries are involved.

My own car (Vitara) has sensors fitted in the wheels and the one time the symbol came on, it showed the pressure in each tyre (in a little diagram) with the pressure flashing at one tyre. And sure enough, it was correct (3 psi lower than the others). When I inflated that tyre to the correct pressure, the warning disappeared.

The system in the Jazz gives no indication of the actual pressures or where the problem lies.

As one contributor said, the main dealer has to sort it out. If, again, he does not show any interest in sorting it out, I will have to point out to him that it will be illegal to drive the car when it is 4 years old - in 15 months (no NCT cert).

No Hondas have tyre sensors in the tyres.
The system works off the resonation of the tyres plus the "wobble" for want of a better word of the wheels.

The issue is that when tyres start to wear there is an imbalance in the system that throws the light on.
It can also be caused by people hitting footpaths ,potholes etc which is damaging the tyres and causing this wobble to be more pronounced.

It can also be caused if your relative got a single tyre fitted--depending on the tyre that was fitted then that can also throw the system off.

If the light is staying off for a few days and coming back on then you have an underlying issue like Ive mentioned above.

Resetting the light every time isn't fixing the issue--the problem needs to be fixed first and Id say its probably sidewall damage doing it.

Have you checked the tyres for damage?
Did you ever get a tyre fitted?

"Instead of directly measuring the pressure in each tyre, the deflation warning system on this vehicle monitors and compares the rolling radius and rotational characteristics of each wheel and tyre while you are driving, to determine if one or more tyres are significantly under-inflated".

The above is a direct quote from the 2017 Honda Jazz manual (page 443).

That is why I think that there are no pressure sensors fitted to each tyre and that the system is linked to the ABS system.

Also, the valve stems are made of rubber: where pressure sensors are fitted, they are metallic (I have been told). The valve stems on my Vitara (which has pressure sensors) are metallic.

The Honda Fit Forum (referred to earlier by Corks Finest) states that, post 2015, the Honda Fit switched to an ABS based system. That is a USA forum, so I appreciate that it may or may not be 100% relevant to the Jazz.

Anyway, I have checked the tyres again: all seem ok - all seem undamaged, wearing evenly and plenty of thread left.

I am bringing the car again to the Honda dealer next Thursday, so I will see what they come up with.

I just said that--I happen to know someone that works for Honda

Tell them to program the system for "non oem" tyres if they haven't done so already.
That usually fixes it once and for all assuming the tyres are ok.

Thank you Hellrazer. I read your first line as "No, Hondas have tyre sensors in the tyres". My brain inserted a comma after "No", so I totally misinterpreted what you said. Sorry!

Thank you for your tip about programming for "non oem" tyres. I will certainly tell them that.

Thank you for your help. Hope your suggestion sorts it.

I brought the car to the Honda dealer this morning and they assure me that they now have programmed the system for "non oem" tyres.

This is the 3rd time I brought the car to them with this issue: they did not do that on the first 2 occasions they attempted to fix the problem. I suspect that they never knew of the "non oem" TPMS programming option, given their reaction when I suggested it to them, this morning.

I appreciate the advice you gave, Hellrazer. Fingers crossed, I hope this is the end of problem.

Good to hear. They really should have known about it if they are a Honda dealer.
Fingers crossed it keeps the light off.

It's now nearly a month since the Honda dealer programmed the TPMS to "non oem" and the TPMS warning symbol has not appeared since then.

It looks af if the problem is solved.

Thanks for your advice, Hellrazer.

Poulgorm

It is now 5 months since the TPMS was programmed to "Non oem" tyres and the problem has not re-occurred. It is definitely sorted now.

Incidentally, another relative of mine owns a Honda Civic - now 2 years old. Still has the original tyres on the car - loads of thread left - his mileage is low. He phoned me yesterday evening with the same problem as we had - that damn TPMS warning light, which kept coming on. In and out many times to the honda main dealer that he bought the car from - they would reset it and it would come back on again. He is totally exasperated by the problem.

I told him about Hellrazer's solution and he is going back to the garage on Monday.

It is amazing that the non oem solution is not offered by Honda dealers, as a matter of course, when the problem keeps re-occurring.

A serious black mark against them.
