3 acd lights
+1 this is where i would start. if the system bleeds and the lights come on again check the manual and start going through the sensors. if thats not the problem it could be the clutch packs in the t-case or maybe even the seals in the t-case. also if the system will bleed on its own you can rule out the pump. just fyi
i'll kep all those options in mine, i heard mike at baierl is good and he is bleeding it tomorrow and pulling codes from the acd too so i will know tomorrow afternoon, i'll keep you guys informed
