almost all if these I have ran into (and this is about one of the 20 most common error codes these units pop up with) were either the relays (far most common), the connections to the relay box or the box itself not holding the connectors securely, a few were the dash itself.
It may be possible it is the controller itself, or a fuse, (hopefully you have checked all the fuses for a voltage drop first).
when you say the relays "checked out" can you describe further how you tested the relays? have you tried replacing all the relays from a "known good" unit?

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
