Finally got hit with the RCM/No start issue! The three 'twin' pins spots near PCB top left edge (looking at PCB bottom with fuses facing away under where the Air Pump relay is), center one and right one, cold solder joints. VERY hard to see, hardly visible fine cracks completely around the pins, had to use a magnifying headband. I suspect IF more solder was in the 'tray' when this slid along during production, it would have not separated. Regardless, this was not visible with a naked eye. Thought mine was immune to this due to improvements in design/fixes in production BUT, there WAS this black 'magic marker' letters/numbers on top of PCB board where that 6th relay position was. COULD this RCM have been an older one either in stock or returned/fixed (and then installed during vehicle assembly)? Down below diode, an 'ou' was there (at @ neg band) and something like a '97h' (really could not make it out exactly) was about centered on where the relay would have been mounted. Anyway, after the freeflow of new solder (prepped by sucking most of old out), beautifully bright silver across all three 'twin' pins spots. Started right up as 'start' was engaged. Inspection and continuity testing of all relay coils and contacts, passed 100%. Another successful job well done (patting back)!
