Any ideas? I'm talking about the flash to pass feature, not turn signals.

 

You are talking about the flash the high beams feature? I would guess that the multifunction switch is going bad, at least that function is. Time for the multimeter to check for power if that function is that important to you

 

The switch already has some play in the physical movement of it, i.e. it's spongy not crisply clicking between positions, so I had an eye to replacing it soon anyways. Thanks for your input, I really appreciate it. Time to look for some guides on how to access it without any risk of discharging that airbag.
