Hi all, I am new to this forum, and I am glad to know so many guys love EVO!
I just bought a EVO VIII, but now my EVO VIII got all three ACD lights on, and the error code is ‘81’, which means there might be a relay problem (and I tested the ACD pump by myself — it will working if you directly charge it by 12v battery). However, I searched online and find nothing about it. Is there anyone met this kind of problem? I am in FL, is there any great EVO shop to recommend? Any suggestions will be appreciated!
On the other hand, I bought a non-ACD transfer case for my EVO as a backup. Bad things always happen — when I tried to replace the center diff as a QUAIFE center LSD, I found I cannot use this part as a direct replacement for the OEM VISCOUS LSD. Is there anyone had successfully replace the center LSD as QUAIFE center LSD? Any reply will be helpful!

Ive got a 9 w/ACD but have not had the privilege of having to mess w/an error. I certainly like your idea of just eliminating it w/non ACD center diff (less BS. Keep it simple)
Hoping the other members can offer some constructive advice on how to proceed?
Cheers, Joe

Thanks for your reply! Yah I totally agree your idea — I hate the drama caused by electrical component. However, I am still interesting in ACD system, which is almost the best AWD system back to that time. So, I am willing to fix it and at least, I can drive an EVO with ACD for once. After that, I will swap the nonACD transfer case into my EVO for a long time keep.
Also, if you get three lights on right after starting the car it is the pump pressure sensor problem. Pump problem manifests itself as 3 lights after some 15 sec or so..

The thing is: The three lights always on, from ignition on till start the engine. By the way, I had already failed using throttle to activate the ACD pump when ignition on. Thus, I thought there must be some electrical (relay) problem.

could be, but failed pressure sensor produces identical symptoms
