I'd like to see how they rig THAT wire. That fan clutch is filled with a fluid that changes viscosity with temperature. HOW will a software update do ANYTHING to adjust the fan clutch...
I didn't realize they were electro-vicous controlled clutch fans, I thought it was still thermo-viscous like on my truck.
As usual, a very informative and helpful post!

Hey, neither did I, until I had to pull an engine out of one of these vehicles. It was very strange to see a bundle of wires going into the center of the viscous clutch.
