B&G ACP Error Code 15 buffers full - how to clear

[Moontide]

Making some progress on my autopilot - hoping not to have to ship it back to the US.

I was able to get it to come up long enough to get an error code 15. This error code indicates the buffers are full. Says this can happen when the Network data line is shorted to ground. I put a used display in the system and am pretty sure it was defective and that it caused the short.

Question being, does anyone know how to clear the buffers, or other steps to resolve this without sending it to the hospital.

Factory reset (and if so how) or ?
