Software update and tpms relearning???

[parb]

Did the software update make the tpms relearn the tpms sensors?


I just put on my steelies on my Grenadier and I have the mx-sensors on them that I programmed to match the stock sensors. Because I let my brother borrow my programmer I expected the tmps to complain it couldn't find the sensors until I got my programmer back so I could program the right sensor id to the right wheel.

Yet after 10-15 minutes on the highway it read all my tires correctly. I did not put the tires in the right location, they went in randomly. There is almost zero chance I got them right by chance.

Or is possible that the software update made the tpms smarter and it learns the sensors without requiring ineos to reprogram the locations to the car?

I'm super happy about this btw. No more mess with programming and I can rotate the tires myself.

Any else seen this?

Cool! But you could have just gotten lucky with the tire mounting.

deflate one and confirm that it shows the correct one on the screens?

Good call. Will do

It's possible. But very implausible

I think i have given you all false hope.

I let air out of my left front tire but it came up as low air in the front right tire on the display. Right pressure but wrong location in the car UI.

So not great. I'll have to reprogram my tires for the right locations.

Bummer, but at least you/we know now. Thanks for checkng

Before you can use this method make sure that tires are mounted at the postions the ECU believes they are (i.e. if left and right front are mixed up, fix it by swapping them, avoid driving before you have fixed all tire positions).

There is a really cumbersome and time consuming way to swap tires if you have a spare wheel. This goes as follows (A and B are two locations on the vehicle, S is the spare wheel "location", relarning the tire position requires driving until the car reports "tire sensor lost" after which at some point it re-aquires the new sensor. I have the impression that sharp turns speed up the forgetting and re-aquiring):

Position A B S
Tire 1 2 3 --> Swap 1 and 3 and relearn
Tire 3 2 1 --> Swap 2 and 1 and relearn
Tire 3 1 2 --> Swap 2 and 3 and relearn
Tire 2 1 3

As you can see 3 is the spare wheel again, but 1 and 2 have changed location (for those that are into programming, this is "swapping two variables with a third variable")
