Topic: FIS-Control seems malfuntion when shipped.
My friend bought a FIS-Control and I helped to install it on his Golf MK4 R32. After the installation, we switched on the ignition and found the up/down/set button on the wiper stalk did not work. No response at all. I tried flash the firmware to latest 2018/01/28 version and some old 2016 version which works on my MK4 R32, but the 3 button on wiper stalk still not work.
I tried use Android APP to config all kinds of coding of FIS Control, the button still not function.
At last, from the manual, I saw that it says Cable C bridges the wiper buttons, I tried disconnect the Cable C and used wires to connect C1 to C4, C2 to C5, C3 to C6. My up/down/set buttons works again!!
From various test I have done, the wiper is OK, the cluster is OK, the FIS-Control cable seems fine. It seems the FIS-Control accepted the coding, but every time I switched on the ignition, it was always in configuration mode. I don't have to hold the down button in the wiper stalk.
My friend bought two FIS-Control, we will test another set tomorrow to check if the issue only happen on current set.
Could you please help? Is there any other issues that I have to check? Thank you.
