TPMS Reset button wiring

[TheKeymeister]

Hi, I've enabled indirect TPMS on my partners 2012 Octavia. It's got the MK70 ABS pump so needed a physical reset button fitting, which I ordered from Aliexpress for not much money.

 

It's arrived, and there's an amount of de-pinning and re-pinning to the ASR OFF switch to make it come to life.  Unfortunately, none of the wire colours match up and not all of the pin numbers do either.  Although I have ElsaWin it hasn't got the Skoda data unfortunately.  Can anyone point me in the right direction please as to which wires should go where?

 

I've got the following wires in the following places. The green/black/grey ones on the TPMS plug need to join up with ones from the ASR OFF ones, I just have no idea what does what.

 

TPMS reset plug

1- no connection

2- Green

3- Black

4- Red (long wire to ABS pump)

5- no connection

6- Grey

 

ASR OFF plug

1- no connection

2- no connection

3- Grey/blue

4- Grey/black

5- no connection

6- Brown

 

If anyone can confirm the correct pin for the TPMS reset on the ABS pump as well, that would be a big help. Details of it are as follows:-

That seems about right.

 

It's pin 7 for the TPMS button with a MK70m rather than pin 35 as it only has 26 pins on the connector 

 

@Leo52 - how are you getting on with the TPMS button you're fitting at the moment?

Thanks guys, do you know if the ABS pump is looking for a +12v or an earth signal for the TPMS reset?  I'll have a mess about with the multimeter and work out the pins on the TPMS switch I've got, as it doesn't seem to correspond to the above (Chinese quality probably!)

 

This is the one I got in case anyone is interested https://www.aliexpress.com/item/32822662385.html?spm=a2g0s.9042311.0.0.6f574c4dXzFjTX

Looks like a 12v pulse when you press the button, at least based on the diagram here: 

 

Their wiring seems to match the switch you got too

Thanks, that answers it perfectly! 

I did try searching but that thread never appeared for some reason...
