Strangely, these two modules coded without errors.


But there's definitely something wrong now.
After I code these modules, the central locking, for example doesn't work. The rear hatch button doesn't work, neither on the hatch, the center console button or the key. Who knows what else doesn't work.
I suspect it's been burned again by me connecting these newer modules.
When I reconnect the old module with the fins, the central locking works.
And when I press the rear hatch button with the old GM3 module in, I at least hear a clicking inside the GM, so I know it's sending the signal, but the rear hatch actuator probably burned again.



What gives?
