... light up more than 1 DTC code?

I got a 42 4 module H. I cleared it, started diags running for a couple minutes, and it didn't light up again (I hate problems that go away by themselves).

FSM says first 'Intermittent' is to check MEM-Cal module for seating.

If it's not seated, won't it cause ALWAYS at least SEVERAL DTC's, instead of just one??
