Mark V alarm

We have been getting a spurious diagnostic alarm on our T core. The alarm is "DCC I/O card objID #5 reset". When this happens we get a bunch of voter mismatch alarms on the C core. All of these alarms are contact inputs on QD2 DTBA. We checked for loose wiring and did not find anything. We changed the T core TCDA card for QD2. This did not fix our problem. The only other thing I see of note is the P125/N125 voltage on the T core is 60/-65v.

Anyone have any thoughts on this?

Thanks
