So my buddy and myself changed out a clutch to my EVO X 2010. We topped off all of the fluids, (PS) (ACD) (Trans) (TCase) with OEM fluids. We put everything together and when I start roll the 4WD Service is required warning shows up. Tried to disconnect the battery, but that didn't work. The car drives fine, but you also hear a rattling noise, like a marble is jumping around below the floor board. Any suggestions?

 

You have to bleed the ACD/AYC system and then drive it for awhile and it will go away after u bleed it or reset it after you bleed it with the MUT tool.

 

Maybe you didn't install the clutch correctly 100%? The rattling sound could also be the twin disk

 

Just a FYI. You do not need the MUT tool to bleed the ACD/AYC. I bled my own in my garage after relocating the pump.
