The GIA2. The GIAs have been swapped and the problem stays.

Sounds like at this point they're going to have to build a harness and
ring out the graycode lines end-to-end from the GIA2 output through to
the AP computer connector individually. If both GIAs are producing
the issue and two AP computers are doing it, there's got to be
something going wrong in the harness. It's all that's left..

Seems logical to me.

The tech says he is talking to Garmin about the possibility that it is a
software problem, although I cannot imagine how such a thing could appear in
only one of many identical airplanes. Faulty memory chip, maybe?
