Jed, Looks like we had one over-voltage detection event last night. I found out something today with the hardware so I need to tell you what I did when I first encountered this problem last week: I first exchanged ADSP II boards, then COMM boards, and the problem was still on the right side. Then I removed the MSYNC board from the right side and installed another MSYNC board and the problem was still on the right side. I figured the MSYNC board was ok so I assumed it was harnessing or power supply related. Well, this morning I exchanged complete board sets between the right and left sides and the problem changed to the left side! I looked at the rams on the MSYNC board and I noticed that 5K,15K,25K, and 35K are -10 instead of -12 which are on the development system boards. Can this be a problem? Glenn

-10 (100 ns) RAMs should be ok unless they are our old friends the standard power Hyundai parts. (Part number does not say 'LP').
