Front brake lever, No Brake light 2010 GS

My 2010 cam head's front brake lever is not activating the Brake light i do believe that this model is activated via a pressure switch and not by a micro switch in the hand unit, And idea's and Thx in advance.

I also think that the brake lights are controlled by pressure switches in the abs module.
The wiring to the brake light is from the ZFE ecu (central electronic unit) and the switch input is from the ABS module to the ZFE.
I assume that you have the led rear light unit which seem to be reliable the early units with filament bulbs suffered from corrosion .
I would first check the fault codes with a GS911 then the wiring to and from the ZFE ecu.

My 2010 GSA, non abs, has a micro switch at the lever.
I take it just tells the ZFE to turn the brake light off or on?

The wiring diagram that I have just shows the symbols for 2 switches.
I assume they are pressure switches or micro switches depending on an ABS or non ABS system.

As an update, it is possible using a GS911 to see if the brake light switches are working .
If they are then it would narrow your search.
