C32 AMG Supercharger Clutch P0235

I have no idea as to what's the issue, since the clutch works if you put power and it has power reaching it.
The car drives normally, but with no supercharger. Could it be a bad relay? What relays control the supercharger?
My guess is that the circuit runs as a loop, and when the supercharger is needed, it is grounded via a relay and the supercharger engages.
My car has power on both sides, and the clutch engages if i power it directly. Moreover, the IC pump is running according to my scanner, so I am out of ideas.
Update: Harness insulation was damaged - repaired harness and tightened pins. Will look into replacing the harness but this has solved my issue in the meantime.
