Hi all,

I just finished retrofitting my trailer hitch. Everything seems to work fine, except for the brake light. Also I have issues coding the module, only the first byte can be changed (region), all other bytes are throwing an "out of range" exception.

What I have done to troubleshoot:
Replaced fuses
Checked wiring/connectors to/from the module
Tried to change the modules code without longcode helper
Changed WSC
Changed region (US -> braking is using the signal lights which is not allowed in Europe/RoW -> No brake lights)
Used meas. blocks which result in:
Group 003 - Input signals - Goes on and off
Group 005 - Output signals - Nothing happens
Group 008 - Input signals via CAN - Goes on and off

Errors when trailer is connected:
