Ok so the Tech Sheet I have... same as the one posted here. Problem is I cannot perform ANY tests as the touch pads are completely unresponsive. I tried the user interface / display board as well as the main control module to no avail. Now Im guessing that the actual touchpads are bad but since there is no matrix map for the touchpads I cant test the buttons for continuity. So I've ordered the 3rd item, the touchpad, hoping for the best.
