Hello

I have a Opel Corsa D 1.3 CDTI 75hp from 2007. where i swapped the IPC to a one with the big screen, so it has trip computer.
The IPC is fully adopted with PIN and VIN and works fine - No DTCs in IPC, BCM and ECU.

I have changed the wiper stalk to one with buttons at the end to control the IPC. But the new buttons do nothing and cant figure out whats wrong.
So it is not possible to scroll through the trip computer menu with MPG, trip, total gallons and fuel remaining.

In my search and what i can see in other forums the stalk use pin 22 in CIM to BCM to the new buttons, but the car has this wire. So it is not like when you retrofit cruise control and pin 20 is missing.
I have tried to change the Code index in IPC to 006 02 and 008 00 but that is removing i trip computer line from the cluster. The IPC come with code index 046 00 from the scrap car.

I think the problem is in the BCM, but i can not find any information in BCM with OP-COM about trip computer, only about the board computer in canbus is present or not - But that is to GID and do nothing when i change it to present.
The BCM is part nr. 13142241 KS - Code index: 003 04

What setting are am missing to get the wiper stalk to work with the IPC?
