It's quite a convoluted mess of logic in how the DICE decide to turn on the fans at different speeds and when depending on engine temperature and/or A/C engaged.
I could not do a write up on it shorter than what WIS have and that is a handful to read through in itself. But I'm pretty sure they come on in unison at all times so check fuses 6 and 15 in engine compartment and the three relays related to cooling fans and see if it comes on when moving the relays back and forth.
This is where the Tech 2 comes in handy where you can demand the fans on at different speeds and see if the relays click or not and go from there.
