Ultimately, I directly wired the relay to the low beam signal,
bypassing the controller, and miraculously the fog lamps illuminated
whenever the low beams were on.
My assessment on this system:
Fog lamps okay. Control module junk.
My dear Hyundaitech,
Have we entered an age in which "accessories" are no longer
controlled by regular switches via wires, or are we dealing with
a single universal power feed to all components, which are remote
switched by switching modules that are activated by signals in a
universal data stream throughout the vehicle? This sort of system
would require both complex "smart switches" as well as "smart"
local controllers at each device.
If it's data, in your opinion, are we now in an awful knotty
territory in which data can buffet between incompatible systems,
causing components to mysteriously fail for no reason?
I gotta hear this from your mouth, er, fingers.
