RDC error: controller 0x6810, fault code 58635

[Elwin]

Hello,

I've successfully learned a new RDC sensor for my rear wheel, after replacing the battery, using a TMPS activator and GS911.

Attempting the same on the front wheel, I couldn't get the sensor to connect.

I don't remember exactly what I might have done to cause this, but on the next attempt, GS911 said there was "no controller to connect to".

Controller 0x6810, fault code 58635

And now my bike displays both currently mounted, and previously working RDC's as dead.

Any help is greatly appreciated.
