I would look at the design of the F box on ealier years then attempt top match the layout.

Honda Jazz Mk4 2020 - / Re: Spacesaver spare wheel
« Last post by Peter5145 on May 02, 2024, 09:51:22 AM »I carry a full sized spare in my Mk4, strapped down in the boot space.It takes up quite a bit pf space but I can still fit a medium sized suitcase laying on top of the tyre and quite a lot of luggage to its side. More remaining volume than the total boot space in my 2007 Yaris.That seems quite an extreme solution, but I suppose if you're set on that particular model but feel a spare is essential you don't have any alternative. Fewer and fewer cars on the market now even seem to have provision for a spare, let alone having one as standard.

Honda Jazz Mk3 2015 - 2020 / Re: Tyre deflation false alarms
« Last post by Peter5145 on May 02, 2024, 09:43:43 AM »When this first happened to me, just two weeks after taking delivery of my Jazz, I immediately pulled over and checked the tyres and discovered that there was no sign of loss of pressure in any of the tyres. It's happened a few times since then but if the car feels OK I've felt confident enough to drive carefully to the next convenient services. I thought the false alarms could be due to the tyres warming up and the pressures increasing but the handbook says "The low tyre pressure indicator will not come on as a result of over inflation." I just recalibrate the system and the warning goes away - until the next time! I also recalibrate after any routine check and adjustment of tyre pressures.Good to know I'm not the only one!
I do as you say, but it's inconvenient having to stop and check the pressures on what seems like every other longish journey I make.
I can't just assume it's a false alarm, as I did have a genuine alert where there was a puncture and fairly rapid deflation. On this occasion I ended up driving about six miles before stopping to check. Perhaps with hindsight I should have stopped sooner, but obviously if you're on a motorway without hard shoulders that's impossible.
I might try the suggestion of resetting after a fast run to see if that makes any difference.

Honda Jazz Mk4 2020 - / Re: Battery fan loud at speed over 60 km/h
« Last post by Lord Voltermore on May 02, 2024, 09:26:49 AM »I have never noticed mine . Sometimes once you become aware of a noise you tend to concentrate on it and it seems to get worse. Was your check of the vent enough to say nothing has been sucked into the fan such as a leaf or sweet wrapper?
You could ask the dealer to have a listen. They might have a way of getting the fan to run without a test drive. Or try doing a sound recording using your phone that they could listen to.

Honda Jazz Mk4 2020 - / Fuse Boxes Information.
« Last post by Don21 on May 02, 2024, 08:57:02 AM »Hello, Purchased a new Jazz Advance for the wife. Some may wonder why I am asking this question, it relates to an event with the last car she had. The fuse boxes under the bonnet and inside the car ( Passenger footwell ). They have identification like IG Main, IG Main 2 etc. I know IG means Ignition but how do I find out what circuit each fuse protects. Years ago fuse box identifications would say accessories, lights, wipers etc so I knew what a fuse protected. So is there any way I can find a diagram, picture whatever for what each fuse protects. I understand the potential hazards of doing anything in this area but my qualifications and knowledge means I have a complete understanding of modern car electrics. Many thanks for any replies.

Honda Jazz Mk4 2020 - / Battery fan loud at speed over 60 km/h
« Last post by bearer on May 02, 2024, 08:33:20 AM »Hi, I have had a Jazz MK4 for about a year. Recently, my attention has been drawn to the fact that as soon as I exceed 60 kilometers per hour the battery fan (near right rear seat) runs noticeably loud. Not in intervals, just blowing/pulling evenly all the time (at slow speeds it is quiet). Depending on the occupied position in the car it is more or less audible, but in the driving position I can hear it very well.
I'm wondering if by some chance I just didn't pay attention to it before, or if there was some change in the fan's operation after all. I checked the battery vent duct at the right rear seat, it looks OK, the seals seem fine. Is the behavior in your cars the same as mine or is there a defect after all?
Thanks

Honda Jazz Mk3 2015 - 2020 / Re: Tyre deflation false alarms
« Last post by Lord Voltermore on May 02, 2024, 07:27:57 AM »I still think the Honda indirect TPMS system has its advantages. With a direct system the pressure sensor transmitters in the tyre may need to be replaced or serviced if their battery runs low. In which case its sensible to get all 4 done. Also a faulty sensor would be a malfunction that would fail the MOT. Here is a paste from the official MOT testers manual
Tyre pressure monitoring system (TPMS)
The inspection of the tyre pressure monitoring system (TPMS) is for M1 vehicles first used on or after 1 January 2012.
The TPMS warning lamp (see diagram 3) will generally illuminate and go off again when the ignition is switched on. If the system has identified a previous pressure loss, the lamp will remain illuminated. This does not automatically mean the system has a malfunction. In the event of a system malfunction, the lamp may flash a number of times and then remain on.
Warning messages on dashboard displays are not a defect in their own right, but may assist the tester in determining that the warning lamp is illuminated because a malfunction exists.
If it is unclear the warning lamp is indicating a system malfunction and not a simply indicating that one or more tyre pressures are low, then advisory information should be added to the test result.
If the Honda system gives a false alarm it is technically still working as a warning device, albeit over sensitive .
A false alarm is a nuisance, but its only a matter of stopping, checking the tyres are ok, and then resetting the system. Even if you have TPMS you should still check the condition and pressure of your tyres regularly ,although you might not chose to do it on a rainy night in a layby.
