Piwis coding, TPMS

Recommended Posts

Hi, had a non working tpms in Cayenne turbo s 2006. It was just saying learning and System inactive.

Replaced my sensor valves, made no difference.

Purchased a piwis 2 clone, messed around and found the front left antenne had a bad plug connection.

Fixed this, but now getting error 1487. Says to 'Change coding from 12339 to 10339' 

I have no idea what is meant. Is it done in the Piwis? 

Can anyone enlighten me?

Change coding in TPMS from 12339 to 10339 as it told you!

Hi Danny, Thanks for your quick reply. 

I'm a beginner with the Piwis, just got it today, so I have no clue on where this "Change coding" from something to something else is located.

I believe that i have been through all the pages and functions, but have not seen any such option as they instruct me to do.

Would you be able to point me in a direction?

On the first page "Overview" I select Tire Pressure Monitoring System. Then it takes me to the identification page which lists module found and I select that.

After that it is in the TPMS section where I select tabs: Fault codes, live values, Drive links check, coding adaptation maintenance repairs and programming.


Under coding adaptations it only says General coding and in there i can do "System ON" which is on currently, or i can change instrument cluster type..


Under Programming tab I have nothing and it says "No programming rules are available".

With the mouse or pen highlight the item - then the F8 button should show up for changes.


I feel like a dumbdumb.... Went through all the pages again, can't see anywhere to input numbers, besides the wheel ID page..

Do you know what exactly this is about?

update, I have gone into Developer mode E. Now i see a text field labelled "Coding" with a value of 0B28B1.

Here I can't input the 10339 value, because it states that the field must be 3 digits only.

So stuck again 😞
