reset TPMS

[Kithmo]

Simplicity of install sake mostly. Replace the engine with a motor and leave the car in 2nd or 3rd gear.

Instead I used a Tesla SDU in place of my diff.

I think top gear might be less strain on the gearbox.

Tesla use an 9.X:1 reduction gear in the SDU/LDU.

Most ICE vehicles use a reduction to the diff of around 4:1. So I assume some gear reduction is required via the gearbox for the best drivability.

I know Zero EV do a motor you can connect to your gearbox, or a motor with reduction gear you can connect to the prop shaft.

Top gear (usually 1:1) through a diff (4.X:1) is too high. Tesla S/LDUs use a 9.X:1 ratio reduction box. So a lower gear in combination with the diff achieve similar.

2021 Mk1 ZS EV here. So what I can gather from this thread: it is NOT possible to reset the TPMS ourselves? Have had a good look at the manual & elsewhere ...

Apparent problem: after a service & wheel rotate, the pressure readings seem odd & wrong; in particular, the FL wheel consistently shows lower than what it should be. I'm assuming therefore that the service centre may not have bothered to reset the TPMS after the service & rotate.

PITA tho, don't really want to have to lose a day, go back to service again etc. I would have thought there would be a user way to do this. Slegehammer? Maybe disconnect the 12v battery & re-set?

Thanks in advance.

Gen 1 needs reprogramming after rotation
Gen2 auto reprograms

It gives me constant readings which is great for motorways etc.

How are pressure readings useful for motorways? What do you do with them?

All you need to do is keep the tyres at 2.8 (don't stress too much if they are 2.7 from time to time) that's all...and nothing to worry if it changes between 2.7 and 2.9 as that depends on the temperature as well and changes slightly as you drive. Tyre pressure outside recommended wears out your tyres a bit more and range might reduce a bit with under inflated tyres ... Just pump them up from time to time as needed
