Power Gear Leveling Communication issue

Okay, did a little more checking with my DVM and coach running. My control box is providing +12v dc on pins 1-3 when the service manual says pins 1 & 2 should measure 5-7v dc. I sent a message to PG to see if they can validate the control box is bad (may have blown the touch pad as well)before I order any parts. Hopefully they will say its okay to have 12v dc on those, but I'm thinking their response is going to say control box is putting out to much dc on pins 1 & 2.

Got to love fixing stuff on these things.. :)
